Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	2. Summary of Significant Accounting Policies Basis of Preparation and Consolidation The accompanying Consolidated Financial Statements have been prepared from the books and records of LyondellBasell N.V. under accounting principles generally accepted in the United States (“U.S. GAAP”). Subsidiaries are defined as being those companies over which we, either directly or indirectly, have control through a majority of the voting rights or the right to exercise control or to obtain the majority of the benefits and be exposed to the majority of the risks. Subsidiaries are consolidated from the date on which control is obtained until the date that such control ceases. All intercompany transactions and balances have been eliminated in consolidation. Cash and Cash Equivalents Our cash equivalents consist of highly liquid debt instruments such as certificates of deposit, commercial paper and money market accounts with major international banks and financial institutions. Cash equivalents include instruments with maturities of three months or less when acquired and exclude restricted cash. Short-Term Investments Our investments in debt securities are classified as available-for-sale and held-to-maturity on the basis of our intent and ability to hold the investments. Investments classified as available-for-sale are carried at fair value with changes reflected in other comprehensive income. Credit-related impairment, measured using the expected cash flows and limited to the amount by which the amortized cost basis of a security exceeds its fair value, is recognized through an allowance for expected credit losses, and adjusted subsequently if conditions change, with a corresponding impact in earnings. Where there is an intention or a requirement to sell an impaired available-for-sale debt security, the entire impairment is recognized in earnings with a corresponding adjustment to the amortized cost basis of the security. Investments classified as held-to-maturity are carried at amortized cost less allowance for credit losses recorded through net income. Trade Receivables Trade receivables are amounts due from customers for merchandise sold or services performed in the ordinary course of business and are carried at transaction price net of allowance for credit losses. Allowance for credit losses is measured using historical loss rates for the respective risk categories and incorporating forward-looking estimates. The corresponding expense for the loss allowance is reflected in Selling, general and administrative expenses. Inventories Cost of our raw materials, work-in-progress and finished goods inventories is determined using the last-in, first-out (“LIFO”) method and is carried at the lower of cost or market value. Cost of our materials and supplies inventory is determined using the moving average cost method and is carried at the lower of cost and net realizable value. Inventory exchange transactions, which involve fungible commodities, are not accounted for as purchases and sales. Any resulting volumetric exchange balances are accounted for as inventory, with cost determined using the LIFO method. Property, Plant and Equipment Property, plant and equipment are recorded at historical cost. Historical cost includes expenditures that are directly attributable to the acquisition of the items. Costs may also include borrowing costs incurred on debt during construction of major projects exceeding one year, costs of major maintenance arising from turnarounds of major units and legally obligated decommissioning costs. Routine maintenance costs are expensed as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of assets to their residual values. The residual values and useful lives of assets are reviewed, and adjusted if appropriate, whenever events or circumstances indicate that a revision is warranted. Land is not depreciated. We evaluate property, plant and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Long-lived assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets, which, for us, is generally at the plant group level (or, at times, individual plants in certain circumstances where we have isolated production units with separately identifiable cash flows). If it is determined that an asset or asset group’s carrying value exceeded its undiscounted estimated pre-tax cash flows and estimated fair value, the asset is written down to its estimated fair value. Gain or loss on retirement or sale of property, plant and equipment is recognized in Other income (expense), net. Equity Investments We account for equity method investments (“equity investments”) using the equity method of accounting if we have the ability to exercise significant influence over, but not control of, an investee. Significant influence generally exists if we have an ownership interest representing between 20% and 50% of the voting rights. Under the equity method of accounting, investments are stated initially at cost and are adjusted for subsequent additional investments and our proportionate share of profit or losses and distributions. We record our share of the profits or losses of the equity investments, net of income taxes, in the Consolidated Statements of Income. When our share of losses in an equity investment equals or exceeds the carrying amount of our investment including advances made by us, we do not recognize further losses, unless we have guaranteed obligations or are otherwise committed to provide further financial support to the investee. We assess our equity investments for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment may not be recoverable. If the decline in value is considered to be other-than-temporary, the investment is written down to its estimated fair value. Investments in PO Joint Ventures and the Louisiana Joint Venture —We share ownership with Covestro PO LLC, a subsidiary of Covestro AG (collectively “Covestro”), in a U.S. propylene oxide (“PO”) manufacturing joint venture (the “U.S. PO Joint Venture”). The U.S. PO Joint Venture owns a PO/styrene monomer (“SM” or “styrene”) and a PO/tertiary butyl alcohol (“TBA”) manufacturing facility. Covestro’s ownership interest in Series A partnership units represents an undivided interest in certain U.S. PO Joint Venture assets with correlative PO capacity reservation that resulted in ownership of annual in-kind cost-based PO production of approximately 680 thousand tons in 2021 and 2020. Our ownership interest in Series A and Series B partnership units conveys us an undivided interest in certain U.S. PO Joint Venture assets with correlative PO and co-product capacity, respectively, resulting in the ownership of annual in-kind cost-based PO and co-product production. In addition, each partner has a 50% interest in a separate manufacturing joint venture (the “European PO Joint Venture”), which owns a PO/SM plant at Maasvlakte near Rotterdam, The Netherlands. In substance, each partner’s ownership interest represents an undivided interest in all of the European PO Joint Venture assets with correlative capacity reservation resulting in ownership of annual in-kind cost-based PO and SM production. We do not share marketing or product sales under the U.S. PO Joint Venture. We operate the U.S. PO Joint Venture’s and the European PO Joint Venture’s (collectively the “PO Joint Ventures”) plants and arrange and coordinate the logistics of product delivery. The partners’ share in the cost of production and logistics is based on their product off-take. During the fourth quarter of 2020, we executed a joint venture agreement with Sasol Chemicals (USA) LLC (“Sasol”) to form the Louisiana Integrated PolyEthylene JV LLC joint venture (the “Louisiana Joint Venture”). Under this arrangement, we acquired a 50% ownership interest in an ethane cracker, a low-density and linear-low density polyethylene plants, and associated infrastructure. Under the terms of the joint venture agreement, each partner provides pro-rata share of ethane feedstocks and off-takes pro-rata shares of cracker and polyethylene products. We operate the Louisiana Joint Venture assets and market the polyethylene off-take for all partners through our global sales team. We account for the PO Joint Ventures and the Louisiana Joint Venture using the equity method. We report the cost of our product off-take as inventory and the equity loss as cost of sales in our Consolidated Financial Statements. Related production cash flows are reported in the operating cash flow section of the Consolidated Statements of Cash Flows. Our equity investment in the PO Joint Ventures and the Louisiana Joint Venture represents our share of the manufacturing plants and is decreased by recognition of our share of equity loss, which is equal to the depreciation of the assets of these joint ventures. Other changes in the investment balance are principally due to our additional capital contributions to these joint ventures to fund capital expenditures. Such contributions are reported in the investing cash flow section of the Consolidated Statements of Cash Flows. Our product off-take of PO and its co-products from the PO Joint Ventures was 2.6 million tons in 2021, 2.6 million tons in 2020 and 2.4 million tons in 2019. Our product off-take of ethylene and polyethylene produced from the Louisiana Joint Venture in 2021 was 1.1 million tons. The product off-take in 2020 for the period subsequent to the formation of the joint venture was immaterial. Redeemable Non-controlling Interests Our redeemable non-controlling interests relate to shares of cumulative perpetual special stock (“redeemable non-controlling interest stock”) issued by our consolidated subsidiary, formerly known as A. Schulman, Inc. (“A. Schulman”). Holders of redeemable non-controlling interest stock are entitled to receive cumulative dividends at the rate of 6% per share on the liquidation preference of $1,000 per share. Redeemable non-controlling interest stock may be redeemed at any time at the discretion of the holders and is reported in the Consolidated Balance Sheets outside of permanent equity. The redeemable non-controlling interests were recorded at fair value at the date of acquisition and are subsequently carried at the greater of estimated redemption value at the end of each reporting period or the initial amount recorded at the date of acquisition adjusted for subsequent redemptions. Dividends on these shares are deducted from or added to the amount of Income (loss) attributable to the Company shareholders if and when declared by the Company. Goodwill Goodwill is tested for impairment annually in the fourth quarter or whenever events or changes in circumstances indicate that the fair value of a reporting unit with goodwill is below its carrying amount. We first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. Qualitative factors assessed for each of the reporting units include, but are not limited to, changes in long-term commodity prices, discount rates, competitive environments, planned capacity, cost factors such as raw material prices, and financial performance of the reporting units. If the qualitative assessment indicates that it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value, a quantitative test is required. If the carrying value of the reporting unit including goodwill exceeds its fair value, an impairment charge equal to the excess would be recognized up to a maximum amount of goodwill allocated to that reporting unit. For 2021 and 2020, management performed qualitative impairment assessments of our reporting units, which indicated that the fair value of our reporting units was greater than their carrying value including goodwill. Based on this assessment, our historical assessment for impairment and forecasted demand for our products, a quantitative goodwill impairment test was not required and no goodwill impairment was recognized. Intangible Assets Intangible assets consist of customer relationships, trade names and trademarks, know-how, emission allowances, various contracts, in-process research and development costs and software costs. These assets are amortized using the straight-line method over their estimated useful lives or over the term of the related agreement. We evaluate definite-lived intangible assets with the associated long-lived asset group for impairment whenever impairment indicators are present. Research and Development Research and development (“R&D”) costs are expensed when incurred. Subsidies for R&D are included in Other income (expense), net. Depreciation expense related to assets employed in R&D is included as a cost of R&D. Income Taxes The income tax for the period comprises current and deferred tax. Income tax is recognized in the Consolidated Statements of Income, except to the extent that it relates to items recognized in other comprehensive income or directly in equity. In these cases, the applicable tax amount is recognized in other comprehensive income or directly in equity, respectively. Deferred income taxes reflect the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts recognized for income tax purposes, as well as the net tax effects of net operating loss carryforwards. Valuation allowances are provided against deferred tax assets when it is more likely than not that some portion or all of the deferred tax asset will not be realized. We recognize uncertain income tax positions in our financial statements when we believe it is more likely than not, based on the technical merits, that the position or a portion thereof will be sustained upon examination. For a position that is more likely than not to be sustained, the benefit recognized is measured at the largest cumulative amount that is greater than 50 percent likely of being realized. Other Provisions Environmental Remediation Costs —Environmental remediation liabilities include liabilities related to sites we currently own, sites we no longer own, as well as sites where we have operated that belong to other parties. Liabilities for anticipated expenditures related to investigation and remediation of contaminated sites are accrued when it is probable a liability has been incurred and the amount of the liability can be reasonably estimated. Only certain post-remediation monitoring costs, the timing of which can be determined with reasonable certainty, are discounted to present value. Asset Retirement Obligations— At some sites, we are legally obligated to decommission our plants upon site exit. Asset retirement obligations are recorded at the fair value using the present value of the estimated costs to retire the asset at the time the obligation is incurred. That cost, which is capitalized as part of the related long-lived asset, is depreciated on a straight-line basis over the remaining useful life of the related asset. Accretion expense in connection with the discounted liability is also recognized over the remaining useful life of the related asset. Such depreciation and accretion expenses are included in Cost of sales. Foreign Currency Translation and Remeasurement Functional and Reporting Currency —Items included in the financial information of each of LyondellBasell N.V.’s entities are measured using the currency of the primary economic environment in which the entity operates (“the functional currency”) and then translated to the U.S. dollar (“the reporting currency”) as follows: • Assets and liabilities for each balance sheet presented are translated at the closing rate at the date of that balance sheet; • Income and expenses for each income statement are translated at monthly average exchange rates; and • All resulting exchange differences are recognized as a separate component within Other comprehensive income (foreign currency translation adjustments). Transactions and Balances —Foreign currency transactions are recorded in their respective functional currency using exchange rates prevailing at the dates of the transactions. Exchange gains and losses resulting from the settlement of such transactions and from remeasurement of monetary assets and liabilities denominated in foreign currencies at the balance sheet date are recognized in earnings. Revenue Recognition Substantially all our revenues are derived from contracts with customers. We account for contracts when both parties have approved the contract and are committed to perform, the rights of the parties and payment terms have been identified, the contract has commercial substance and collectability is probable. Revenue is recognized when obligations under the terms of a contract with our customer are satisfied. This generally occurs at the point in time when performance obligations are fulfilled and control transfers to the customer. In most instances, control transfers upon transfer of risk of loss and title to the customer, which usually occurs when we ship products to the customer from our manufacturing facility. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods. Customer incentives are generally based on volumes purchased and recognized over the period earned. Sales, value-added, and other taxes that we collect concurrent with revenue-producing activities are excluded from the transaction price as they represent amounts collected on behalf of third parties. We apply the practical expedient to recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that we otherwise would have recognized is one year or less. Shipping and handling costs are treated as a fulfillment cost and not a separate performance obligation. We have marketing arrangements to off-take and sell the production of some of our joint ventures in return for a percentage of the price realized on the sales to the end customer. In such arrangements, when we obtain control of the product, revenue and cost of sales are presented on a gross basis. Otherwise, we recognize revenue, net of amounts due to the joint venture, which represents commissions earned. Payments are typically required within a short period following the transfer of control of the product to the customer. We occasionally require customers to prepay purchases to ensure collectability. Such prepayments do not represent financing arrangements, since payment occurs within a short time frame. We apply the practical expedient which permits us to disregard the effects of a significant financing component when, at contract inception, we expect the period between the payment and fulfillment of the performance obligation will be one year or less. Contract balances typically arise when a difference in timing between the transfer of control to the customer and receipt of consideration occurs. Our contract liabilities, which are reflected in our Consolidated Financial Statements as Accrued liabilities and Other liabilities, consist primarily of customer payments for products or services received before the transfer of control to the customer occurs. Share-Based Compensation The Company recognizes compensation expense in the financial statements for equity-classified share-based compensation awards based upon the grant date fair value over the vesting period. See Note 15 to the Consolidated Financial Statements for additional information. Leases Leases with a term longer than 12 months are recorded on the balance sheet as a lease asset and lease liability. If at inception of a contract, a lease is identified, we recognize a lease asset and a corresponding lease liability based on the present value of the lease payments over the lease term, discounted using our incremental borrowing rate, unless an implicit rate is readily determinable. Lease payments include fixed and variable lease components derived from usage or market-based indices, such as the consumer price index. Other variable lease payments may fluctuate for a variety of reasons including usage, output, insurance or taxes. These variable amounts are expensed as incurred and not included in the lease assets or lease liabilities. Options to extend or terminate a lease are reflected in the lease payments and lease term when it is reasonably certain that we will exercise those options. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the Consolidated Statements of Income. The majority of our leases are operating leases for which we recognize lease expense on a straight-line basis over the lease term. We apply the practical expedient to account for lease and associated non-lease components as a single lease component for all asset classes with the exception of utilities and pipeline assets within major manufacturing equipment. For these assets, non-lease components are separated from lease components and accounted for as normal operating expenses. Leases with an initial term of 12 months or less are recognized in the Consolidated Statements of Income on a straight-line basis over the lease term. Financial Instruments and Hedging Activities Pursuant to our risk management policies, we selectively enter into derivative transactions to manage market risk volatility associated with changes in commodity pricing, currency exchange rates and interest rates. Certain derivatives used for this purpose are designated as net investment hedges, cash flow hedges or fair value hedges. Derivative instruments are recorded at fair value on the balance sheet. Gains and losses related to changes in the fair value of derivative instruments not designated as hedges are recorded in earnings. Cash flows from derivatives designated as hedges are reported in our Consolidated Statements of Cash Flows under the same category as the cash flows from the hedged items unless the derivative contract contains a significant financing element. Cash flows for derivatives with a significant financing element are classified as Cash flows from financing activities. Cash flows related to economic hedges are classified consistent with the cash flows of the economic hedged items. Net Investment Hedges— We enter into foreign currency derivatives and foreign currency denominated debt to reduce the volatility in shareholders’ equity resulting from changes in currency exchange rates of our foreign subsidiaries with respect to the U.S. dollar. Our foreign currency derivatives consist of cross-currency contracts and forward exchange contracts. We use the critical terms approach through the application of the spot method to assess hedge effectiveness at least quarterly. For derivatives designated as net investment hedges, gains or losses attributable to changes in spot foreign exchange rates over the designation period are reflected in foreign currency translation adjustments within Other comprehensive income (loss). Recognition in earnings is delayed until the net investment is sold or liquidated. At that time, the amount recognized is reported in the same line item as the gain or loss on the liquidation of the hedged foreign operations. For our cross-currency swaps, the associated interest receipts and payments are recorded in interest expense. For our foreign currency forward contracts, we amortize initial forward point values on a straight-line basis to interest expense over the life of the hedging instrument. We monitor on a quarterly basis for any over-hedged positions requiring re-designation and re-designation of the hedge to remove such over-hedged condition. Cash Flow Hedges— We enter into cash flow hedges to manage the variability in cash flows of a future transaction. Our cash flow hedges include cross currency swaps, forward starting interest rate swaps and commodity futures, options and swaps. For derivatives designated as cash flow hedges, the gains and losses are recorded in other comprehensive income (loss) and released to earnings in the same line item and in the same period during which the hedged item affects earnings. We use the critical terms and the quantitative long-haul methods to assess hedge effectiveness and monitor, at least quarterly, any change in effectiveness. We have cross-currency swap contracts designated as cash flow hedges to reduce our exposure to the foreign currency exchange risk associated with certain intercompany loans. Under the terms of these contracts, we make interest payments in euros and receive interest in U.S. dollars. Upon the maturities of these contracts, we will pay the principal amount of the loans in euros and receive U.S. dollars from our counterparties. We enter into forward-starting interest rate contracts to mitigate the risk of adverse changes in benchmark interest rates on future anticipated debt issuances. We also execute commodity futures, options and swaps to manage the volatility of the commodity price related to anticipated purchases of raw materials and product sales. We enter into over-the-counter commodity swaps and options with one or more counterparties whereby we pay a predetermined fixed price and receive a price based on the average monthly rate of a specified index for the specified nominated volumes. Fair Value Hedges— We use interest rate swaps as part of our current interest rate risk management strategy to achieve a desired proportion of variable versus fixed rate debt. Under these arrangements, we exchange fixed-rate for floating-rate interest payments to effectively convert our fixed-rate debt to floating-rate debt. For derivatives that have been designated as fair value hedges, the gains and losses of the derivatives and hedged items are recorded in earnings. We use the long-haul method to assess hedge effectiveness using a regression analysis approach at least quarterly. We perform the regression analysis over an observation period of three years, utilizing data that is relevant to the hedge duration. Fair Value Measurements We categorize assets and liabilities, measured at fair value, into one of three different levels depending on the observability of the inputs employed in the measurement. Level 1 inputs are quoted prices for identical instruments in active markets. Level 2 inputs are quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs or significant value-drivers are observable. Level 3 inputs are model-derived valuations in which one or more significant inputs or significant value-drivers are unobservable. Fair value measurements are classified according to the lowest level input or value-driver that is significant to the valuation. A measurement may therefore be classified within Level 3 even though there may be significant inputs that are readily observable. Changes in Fair Value Levels —Management reviews the disclosures regarding fair value measurements at least quarterly. If an instrument classified as Level 1 subsequently ceases to be actively traded, it is transferred out of Level 1. In such cases, instruments are reclassified as Level 2, unless the measurement of its fair value requires the use of significant unobservable inputs, in which case it is reclassified as Level 3. We use the following inputs and valuation techniques to estimate the fair value of our financial instruments disclosed in Note 13 to the Consolidated Financial Statements: Cross-Currency Swaps —The fair value of our cross-currency swaps is calculated using the present value of future cash flows discounted using observable inputs such as known notional value amounts, yield curves, basis curves, as applicable, and with the foreign currency leg revalued using published spot and forward exchange rates on the valuation date. Forward-Starting and Fixed-for-Floating Interest Rate Swaps —The fair value of our forward-starting and fixed-for-floating interest rate swaps is calculated using the present value of future cash flows using observable inputs such as benchmark interest rates and market yield curves. Commodity Derivatives —The fair values of our commodity derivatives are measured using closing market prices of public exchanges and from third-party broker quotes and pricing providers. The fair value of our commodity swaps classified as Level 2 is determined using a combination of observable and unobservable inputs. The observable inputs consist of future market values of various crude and heavy fuel oils, which are readily available through public data sources. The unobservable input, which is the estimated discount or premium used in the market pricing, is calculated using an internally-developed, multi-linear regression model based on the observable prices of the known components and their relationships to historical prices. A significant change in this unobservable input would not have a material impact on the fair value measurement of our Level 2 commodity swaps. Forward Exchange Contracts —The fair value of our forward exchange contracts is based on forward market rates. Available-for-Sale Debt Securities— The fair value of our available-for-sale debt securities is calculated using observable market data for similar securities and broker quotes from recognized purveyors of market data. Equity Securities— The fair value of our investment in equity securities is based on the net asset value provided by the fund administrator. Short-Term Debt —The fair value of short-term borrowings related to precious metal financing arrangements accounted for as embedded derivatives are determined based on the future price of the associated precious metal. Long-Term Debt —The fair value of our senior and guaranteed notes is calculated using pricing data obtained from well-established and recognized vendors of market data for debt valuations. The fair value of our term loan was determined based on a discounted cash flow model using observable inputs such as benchmark interest rates and public information regarding our credit risk. We use the following inputs and valuation techniques to estimate the fair value of our pension assets disclosed in Note 14 to the Consolidated Financial Statements: Common and Preferred Stock— Valued at the closing price reported on the market on which the individual securities are traded. Fixed Income Securities— Certain securities that are not traded on an exchange are valued at the closing price reported by pricing services. Other securities are valued based on yields currently available on comparable securities of issuers with similar credit ratings. Commingled Funds— Valued based upon the unit values of such collective trust funds held at year end by the pension plans. Unit values are based on the fair value of the underlying assets of the fund derived from inputs principally from, or corroborated by, observable market data by correlation or other means. Real Estate— Valued on the basis of a discounted cash flow approach, which includes the future rental receipts, expenses, and residual values as the highest and best use of the real estate from a market participant view as rental property. Hedge Funds— Valued based upon the unit values of such alternative investments held at year end by the pension plans. Unit values are based on the fair value of the underlying assets of the fund. Private Equity— Valued based upon the unit values of such alternative investments held at year end by the pension plans. Unit values are based on the fair value of the underlying assets of the fund. Certain securities held in the fund are valued at the closing price reported on an exchange or other established quotation service for over-the-counter securities. Other assets held in the fund are valued based on the most recent financial statements prepared by the fund manager. Convertible Securities— Valued at the quoted prices for similar assets or liabilities in active markets. U.S. Government Securities— Certain securities are valued at the closing price reported on the active market on which the individual securities are traded. Other securities are valued based on yields currently available on comparable securities of issuers with similar credit ratings. Cash and Cash Equivalents— Valued at the q

Revenue from Contract with Customer [Abstract]
Revenues [Text Block]	3. Revenues Contract Balances— Contract liabilities were $169 million and $194 million at December 31, 2021 and 2020, respectively. Revenue recognized in each reporting period, included in the contract liability balance at the beginning of the period, was immaterial. Disaggregation of Revenues —We participate globally across the petrochemical value chain and are an industry leader in many of our product lines. Our chemicals businesses consist primarily of large processing plants that convert large volumes of liquid and gaseous hydrocarbon feedstocks into plastic resins and other chemicals. Our chemical products tend to be basic building blocks for other chemicals and plastics. Our plastic products are used in large volumes as well as smaller specialty applications. Our refining business consists of our Houston refinery, which processes crude oil into refined products such as gasoline and distillates. Revenues disaggregated by key products are summarized below: Year Ended December 31, Millions of dollars 2021 2020 2019 Sales and other operating revenues: Olefins & co-products $ 5,008 $ 2,432 $ 2,957 Polyethylene 10,134 5,842 6,070 Polypropylene 7,994 4,525 5,010 Propylene oxide and derivatives 2,885 1,714 1,924 Oxyfuels and related products 3,587 2,278 3,116 Intermediate chemicals 3,415 2,080 2,516 Compounding and solutions 4,132 3,223 4,096 Advanced polymers 1,001 680 750 Refined products 7,178 4,346 7,599 Other 839 633 689 Total $ 46,173 $ 27,753 $ 34,727 The following table presents our revenues disaggregated by geography, based upon the location of the customer: Year Ended December 31, Millions of dollars 2021 2020 2019 Sales and other operating revenues: United States $ 22,526 $ 12,113 $ 16,349 Germany 3,395 2,113 2,708 China 2,322 1,474 1,225 Italy 1,828 1,175 1,435 Mexico 1,572 1,197 1,634 France 1,431 875 1,345 Japan 1,417 876 1,039 The Netherlands 1,390 785 929 Poland 1,169 926 960 Other 9,123 6,219 7,103 Total $ 46,173 $ 27,753 $ 34,727 Transaction Price Allocated to the Remaining Performance Obligations —We have elected to exclude contracts which have an initial term of one year or less from this disclosure. Our contracts with customers are commodity supply arrangements that settle based on market prices at future delivery dates; therefore, transaction prices are entirely variable. Transaction prices are known at the time revenue is recognized since they are generally determined by the commodity price index at a specific date, at month-end or at the month average once products are shipped to our customers. Future estimates of transaction prices for disclosure purposes are substantially constrained as they are highly susceptible to factors outside our influence, including volatility in commodity markets, industry production capacities and operating rates, planned and unplanned industry operating interruptions, foreign exchange rates and worldwide geopolitical trends.

Inventories Inventories consisted of the following components at December 31: Millions of dollars 2021 2020 Finished goods $ 3,329 $ 2,816 Work-in-process 178 144 Raw materials and supplies 1,394 1,384 Total inventories $ 4,901 $ 4,344 At December 31, 2021 and 2020, approximately 80% and 81%, respectively, of our inventories were valued using the last in, first out (“LIFO”) method and the remaining inventories, consisting primarily of materials and supplies, were valued at the moving average cost method. At December 31, 2021 and 2020, our LIFO cost exceeded current replacement cost under the first-in first-out method. The excess of our inventories at estimated net realizable value over LIFO cost after lower of cost or market (“LCM”) charges was approximately $2,503 million and $601 million at December 31, 2021 and 2020, respectively. We recognized an LCM inventory valuation charge of $16 million and $33 million during 2020 and 2019, respectively. These charges primarily related to the decline in pricing for our raw material and finished goods inventories and in domestic polyethylene prices, respectively.

In 2021, 2020 and 2019, we capitalized interest of $97 million, $40 million and $87 million, respectively. Intangible Assets —The components of identifiable intangible assets, at cost, and the related accumulated amortization are as follows at December 31: 2021 2020 Millions of dollars Cost Accumulated Net Cost Accumulated Net Emission allowances $ 740 $ (504) $ 236 $ 846 $ (611) $ 235 Various contracts 435 (357) 78 456 (351) 105 Customer relationships 303 (68) 235 308 (51) 257 In-process research and development costs 109 (97) 12 117 (96) 21 Trade name and trademarks 104 (93) 11 108 (88) 20 Know-how 83 (37) 46 86 (27) 59 Software costs 158 (81) 77 122 (68) 54 Total intangible assets $ 1,932 $ (1,237) $ 695 $ 2,043 $ (1,292) $ 751 Amortization of these identifiable intangible assets for the next five years is expected to be $83 million in 2022, $76 million in 2023, $67 million in 2024, $64 million in 2025 and $46 million in 2026. Impairments —During the fourth quarter of 2021 and during the third quarter of 2020, we identified impairment triggers relating to our Houston refinery’s asset group which resulted in non-cash impairment charges of $624 million and $582 million, respectively. In September 2021, we announced we were weighing strategic options, including a potential sale, for our Houston refinery. The subsequent evaluation of strategic options during the fourth quarter of 2021 increased the likelihood of the asset’s disposal prior to the end of its expected useful life. As a result of this impairment indicator, we assessed the Houston refinery for impairment in the fourth quarter of 2021 and determined that its carrying value exceeded its estimated undiscounted pre-tax cash flows. We estimated the fair values of the Houston refinery’s property, plant and equipment, materials and supplies and intangible assets were all zero as of December 31, 2021. Given this, our Refining segment recognized a $624 million non-cash impairment charge in the fourth quarter of 2021 that includes a $549 million impairment of property, plant and equipment, a $43 million impairment of materials and supplies and a $32 million impairment of intangible assets, which reduced the assets’ carrying values to their fair values. The fair values of the impaired assets were determined using market information provided by unrelated third parties. The fair value measurement for the asset group is classified as Level 3. During 2020, prior to the Company’s evaluation of strategic options for the Houston refinery, we identified impairment triggers relating to our Houston refinery’s asset group as a result of significant negative impacts to the Refining segment forecasted cash flows resulting from the COVID-19 pandemic. We assessed the Houston refinery for impairment and determined that the asset group carrying value exceeded its undiscounted estimated pre-tax cash flows. As of September 30, 2020, we estimated the fair value of the Houston refinery’s property, plant and equipment to be $550 million, and fair value of contract intangible assets to be $10 million, which was less than the carrying value. As a result, our Refining segment recognized a non-cash impairment charge in the third quarter of 2020 of $582 million, which included a $570 million impairment of property, plant and equipment and a $12 million impairment of contract intangible assets, which reduced the assets’ carrying values to their fair values. The fair value of the impaired assets was determined using an income approach that was based on significant inputs that were not observable in the market. The fair value measurement for the asset group is classified as Level 3. Depreciation and Amortization Expense —Depreciation and amortization expense is summarized as follows: Year Ended December 31, Millions of dollars 2021 2020 2019 Property, plant and equipment $ 1,146 $ 1,143 $ 1,092 PO Joint Ventures and Louisiana Joint Venture 156 72 49 Emission allowances 12 58 63 Various contracts 20 20 32 Customer relationships 20 20 24 In-process research and development costs 8 8 8 Trade name and trademarks 8 45 30 Know-how 11 11 12 Software costs 12 8 2 Total depreciation and amortization $ 1,393 $ 1,385 $ 1,312 Asset Retirement Obligations —In certain cases, we are contractually obligated to decommission our plants upon site exit. In such cases, we have accrued the net present value of the estimated costs. The majority of our asset retirement obligations are related to facilities in Europe. The changes in our asset retirement obligations are as follows: Year Ended December 31, Millions of dollars 2021 2020 Beginning balance $ 64 $ 65 Payments (3) (6) Changes in estimates 3 (2) Accretion expense 2 2 Effects of exchange rate changes (4) 5 Ending balance $ 62 $ 64 Although we may have asset retirement obligations associated with some of our other facilities, the present value of those obligations is not material in the context of an indefinite expected life of the facilities. We continually review the optimal future alternatives for our facilities. Any decision to retire one or more facilities may result in an increase in the present value of such obligations. Discontinued Operations —We began reporting the Berre refinery as a discontinued operation in the second quarter of 2012. The estimated cost and associated cash flows pertaining to the final closure and dismantlement of our Berre refinery from the Prefect of Bouches du Rhone are not deemed to be material. Goodwill —The changes in the carrying amount of goodwill in each of the Company’s reportable segments for the years ended December 31, 2021 and 2020 were as follows: Millions of dollars O&P – O&P – I&D APS Technology Total December 31, 2019 $ 162 $ 112 $ 228 $ 1,380 $ 9 $ 1,891 Foreign currency translation adjustments — 30 31 (1) 2 62 December 31, 2020 162 142 259 1,379 11 1,953 Foreign currency translation adjustments — (33) (34) (8) (3) (78) December 31, 2021 $ 162 $ 109 $ 225 $ 1,371 $ 8 $ 1,875

Long-Term Debt Senior Revolving Credit Facility— In November 2021, we entered into a second amendment and restatement of our credit agreement (the “Amended and Restated Credit Agreement”) to provide for a $3,250 million senior unsecured revolving credit facility (the “Senior Revolving Credit Facility”) that matures in November 2026. Our Senior Revolving Credit Facility which may be used for dollar and euro denominated borrowings, has a $200 million sub-limit for dollar and euro denominated letters of credit, a $1,000 million uncommitted accordion feature, and supports our commercial paper program. Borrowings under the facility bear interest at either a base rate, LIBOR rate or EURIBOR rate, plus an applicable margin. Additional fees are incurred for the average daily unused commitments. At December 31, 2021, we had no borrowings or letters of credit outstanding and $3,046 million of unused availability under this facility. The facility contains customary covenants and warranties, including specified restrictions on indebtedness and liens. Additionally, we are required to maintain a maximum leverage ratio (calculated as the ratio of total net funded debt to consolidated earnings before interest, taxes and depreciation and amortization, both as defined in the Amended and Restated Credit Agreement) financial covenant of (i) 4.00 to 1.00 for the fiscal quarter ending March 31, 2022; and (ii) 3.50 to 1.00 for the fiscal quarter ending June 30, 2022 and thereafter. In the event an acquisition meeting certain thresholds is consummated at any time after March 31, 2022 we can elect to increase the maximum leverage ratio for each of the first six fiscal quarters ending after such acquisition as indicated in the Amended and Restated Credit Agreement. The Amended and Restated Credit Agreement also removes minimum liquidity requirements for dividends and share repurchases contained in the previous agreement. Term Loan due 2022— In March 2019, LYB Americas Finance Company LLC (“LYB Americas Finance”), a wholly owned subsidiary of LyondellBasell Industries N.V., entered into a $4,000 million senior unsecured delayed draw term loan credit facility that matures in March 2022. Borrowings under the credit agreement were available through December 31, 2019, subsequent to which no further borrowings could be made under the agreement. In October 2020 we repaid $500 million of the indebtedness outstanding under this Term Loan, using the proceeds from guaranteed notes issued in October 2020 as discussed below. In 2021, we repaid the remaining $1,450 million outstanding under our Term Loan due 2022. Outstanding borrowings bore interest at either a base rate or LIBOR rate, as defined, plus in each case, an applicable margin determined by reference to LyondellBasell N.V.’s current credit ratings. The credit agreement contained customary representations and warranties and contained certain restrictive covenants regarding, among other things, secured indebtedness, subsidiary indebtedness, mergers and sales of assets. Covenants and Provisions— Our $300 million 8.1% Guaranteed Notes due 2027, which are guaranteed by LyondellBasell Industries Holdings B.V., a wholly owned subsidiary of LyondellBasell Industries N.V., contain certain restrictions with respect to the level of maximum debt that can be incurred and security that can be granted by certain operating companies that are direct or indirect wholly owned subsidiaries of LyondellBasell Industries Holdings B.V. These notes contain customary provisions for default, including, among others, the non-payment of principal and interest, certain failures to perform or observe obligations under the Agreement on the notes, the occurrence of certain defaults under other indebtedness, failure to pay certain indebtedness and the insolvency or bankruptcy of certain LyondellBasell Industries N.V. subsidiaries. The indentures governing all other notes contain limited covenants, including those restricting our ability and the ability of our subsidiaries to incur indebtedness secured by significant property or by capital stock of subsidiaries that own significant property, enter into certain sale and lease-back transactions with respect to any significant property or enter into consolidations, mergers or sales of all or substantially all of our assets. We may redeem some of our notes in whole or in part, prior to their respective maturity dates, at a redemption price equal to the greater of (i) 100% of the principal amount of the notes redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest (discounted at the applicable treasury yield or comparable government bond rate plus their respective basis points) on the notes to be redeemed. S ome of our notes may also be redeemed prior to their respective maturity dates, at a redemption price equal to 100% of the principal amount of the notes redeemed plus accrued and unpaid interest. Certain notes are also redeemable upon certain tax events. Additionally, our Senior Notes due 2024 may be redeemed and repaid, in whole at any time or in part from time to time prior to the date that is 90 days prior to the scheduled maturity date of the notes at a redemption price equal to 100% of the principal amount of the notes redeemed plus a premium for each note redeemed equal to the greater of 1.00% of the then outstanding principal amount of the note and the excess of: (a) the present value at such redemption date of (i) the principal amount of the note at maturity plus (ii) all required interest payments due on the note through maturity (excluding accrued but unpaid interest), computed using a discount rate equal to the Treasury Rate as of such redemption date plus 50 basis points; over (b) the outstanding principal amount of the note. These notes may also be redeemed, in whole or in part, at any time on or after the date which is 90 days prior to the final maturity date of the notes, at a redemption price equal to 100% of the principal amount of the notes redeemed plus accrued and unpaid interest. As of December 31, 2021, we are in compliance with our debt covenants. Guaranteed Notes— In June 2021, we redeemed $325 million of the outstanding $750 million 4.0% guaranteed notes due 2023. In conjunction with the partial redemption, we recognized $25 million of debt extinguishment costs which are reflected in Interest expense in the Consolidated Statements of Income. The debt extinguishment costs include $23 million paid for make-whole premiums and non-cash charges of $2 million for the write-off of unamortized debt discount and issuance costs. In September 2021, we redeemed the entire $500 million outstanding of 2.875% guaranteed notes due 2025.

The debt extinguishment costs include $71 million paid for make-whole premiums and non-cash charges of $7 million for the write-off of unamortized debt discount and issuance costs, partially offset by $36 million in gains resulting from the write-off of the cumulative fair value hedge accounting adjustments.

We used the net proceeds from the sale of the notes for general corporate purposes, including to increase our liquidity and manage short-term debt maturities. In October 2020, LYB Finance III, issued $3.9 billion of guaranteed notes. The notes included $500 million of 1.25% guaranteed notes due 2025 (the “1.25% 2025 Notes”) at a discounted price of 99.683%; $500 million of 2.25% guaranteed notes due 2030 (the “2.25% 2030 Notes”) at a discounted price of 99.203%; $750 million of 3.375% guaranteed notes due 2040 (the “2040 Notes”) at a discounted price of 99.77%; $1,000 million of 3.625% guaranteed notes due 2051 (the “2051 Notes”) at a discounted price of 99.707%; $500 million of 3.8% guaranteed notes due 2060 (the “2060 Notes”) at a discounted price of 99.166% and $650 million of guaranteed floating rate notes due 2023 (the “Floating Rate Notes”).

We used the proceeds to repay debt as discussed below and the remaining proceeds were used to fund a portion of the purchase price for the Louisiana Joint Venture. In October 2020, we used $500 million of the net proceeds to repay a portion of the indebtedness outstanding under our Term Loan due 2022. In November 2020, proceeds from the October Notes were used to redeem €750 million aggregate principal amount of our 1.875% guaranteed notes due 2022.

Short-Term Debt U.S. Receivables Facility— Our U.S. Receivables Facility has a purchase limit of $900 million in addition to a $300 million uncommitted accordion feature. In June 2021, we extended the term of the facility to June 2024 in accordance with the terms of the agreement. This facility provides liquidity through the sale or contribution of trade receivables by certain of our U.S. subsidiaries to a wholly owned, bankruptcy-remote subsidiary on an ongoing basis and without recourse. The bankruptcy-remote subsidiary may then, at its option and subject to a borrowing base of eligible receivables, sell undivided interests in the pool of trade receivables to financial institutions participating in the facility (“Purchasers”). The sale of the undivided interest in the pool of trade receivables is accounted for as a secured borrowing in the Consolidated Balance Sheets. We are responsible for servicing the receivables. We pay variable interest rates on our secured borrowings. Additional fees are incurred for the average daily unused commitments. In the event of liquidation, the bankruptcy-remote subsidiary’s assets will be used to satisfy the claims of the Purchasers prior to any assets or value in the bankruptcy-remote subsidiary becoming available to us. This facility also provides for the issuance of letters of credit up to $200 million. Performance obligations under the facility are guaranteed by LyondellBasell Industries N.V. The term of the facility may be extended in accordance with the terms of the agreement. The facility is also subject to customary warranties and covenants, including limits and reserves and the maintenance of specified financial ratios. Under the terms of the U.S. Receivable Facility we are required to maintain a maximum leverage ratio consistent with the terms of the Senior Revolving Credit Facility as discussed above. At December 31, 2021, there were no borrowings or letters of credit outstanding and $900 million unused availability under the facility. Commercial Paper Program —We have a commercial paper program under which we may issue up to $2,500 million of privately placed, unsecured, short-term promissory notes (“commercial paper”). This program is backed by our $3,250 million Senior Revolving Credit Facility. Proceeds from the issuance of commercial paper may be used for general corporate purposes, including dividends and share repurchases. Interest rates on the commercial paper outstanding at December 31, 2021 are based on the terms of the notes and range from 0.11% to 0.21%. At December 31, 2021, we had $204 million of outstanding commercial paper. Precious Metal Financings —We enter into lease agreements for precious metals which are used in our production processes. All precious metal borrowings are classified as Short-term debt.

Additional Information Debt Discount and Issuance Costs— Amortization of debt discount and debt issuance costs resulted in amortization expense of $35 million, $21 million and $11 million for the years ended December 31, 2021, 2020 and 2019, respectively, which is included in Interest expense in the Consolidated Statements of Income. Other Information —LYB International Finance B.V., LYB International Finance II B.V., LYB International Finance III, LLC and LYB Americas Finance Company LLC (“LYB Finance subsidiaries”) are wholly owned finance subsidiaries of LyondellBasell Industries N.V., as defined in Rule 3-10(b) of Regulation S-X.

We present the gross assets and liabilities of our derivative instruments on the Consolidated Balance Sheets. Financial Instruments Not Measured at Fair Value on a Recurring Basis —Our derivative instruments are recorded at fair value and precious metal financings are recorded at amortized cost. Our other financial instruments classified within Current assets and Current liabilities have a short maturity and their carrying value generally approximates fair value. Our Long-term debt is recorded at amortized cost. The following table presents the carrying value and estimated fair value of our Precious metal financings and Long-term debt: December 31, 2021 December 31, 2020 Carrying Fair Carrying Fair Millions of dollars Precious metal financings $ 155 $ 130 $ 140 $ 154 Long-term debt 11,218 12,756 15,266 17,290 Total $ 11,373 $ 12,886 $ 15,406 $ 17,444 The financial instruments in the table above are classified as Level 2. Derivative Instruments: We are exposed to market risks, such as changes in commodity prices, interest rates and currency exchange rates. We enter into derivative contracts pursuant to our risk management policies to manage these risks. Commodity Prices —We are exposed to commodity price volatility related to purchases of various feedstocks and sales of our products. We use over-the-counter commodity swaps, options and exchange traded futures contracts to manage these risks, including through cash flow hedging relationships. The following table presents the notional amounts of our outstanding commodity derivative instruments: December 31, 2021 December 31, 2020 Millions of dollars Notional Amount Notional Amount Maturity Date Derivatives designated as hedges: Cash flow hedges $ 41 $ 60 2022 Derivatives not designated as hedges: Commodity contracts 245 184 2022 Interest Rates —We are exposed to interest rate risk with respect to our fixed-rate and variable-rate debt. Fluctuations in interest rates impact the fair value of fixed-rate debt and expose us to the risk that we may need to refinance debt at higher rates. Fluctuations in interest rates also impact interest expense from our variable-rate debt. We use forward-starting interest rate swaps that are designated as cash flow hedges to mitigate the risk that benchmark rates will increase in connection with future financing activities. As of December 31, 2021 and 2020, Other assets included $238 million of collateral related to these forward-starting interest swaps, representing the maximum amount of collateral that may be required under these contracts. We also use interest rate swaps that are designated as fair value hedges to mitigate the changes in the fair value of our fixed-rate debt by effectively converting it to variable-rate debt. See Note 11 to the Consolidated Financial Statements for additional information. The following table presents the notional amounts of our outstanding interest rate derivative instruments: December 31, 2021 December 31, 2020 Millions of dollars Notional Amount Notional Amount Maturity Date Cash flow hedges $ 1,000 $ 1,000 2023 to 2024 Fair value hedges 1,163 122 2025 to 2030 Foreign Currency Rates —We have significant worldwide operations. The functional currencies of our operating subsidiaries are primarily the U.S. dollar and the euro. We enter into transactions denominated in currencies other than our designated functional currencies that create foreign currency exposure. We enter foreign currency contracts to economically hedge foreign currency risk related to recognized foreign currency monetary assets and liabilities. Changes in the fair value of such forward and swap contracts are reported in the Consolidated Statements of Income and offset, in part, currency remeasurement results. In the past, we have entered euro-denominated debt that was designated as a net investment hedge. Other income, net, in the Consolidated Statements of Income reflected foreign currency losses of $2 million, losses of $7 million and gains of $9 million in 2021, 2020 and 2019, respectively. We enter foreign currency contracts that are designated as net investment hedges to manage the impacts of foreign currency translation of our net investments in foreign operations. We also enter foreign currency contracts that are designated as cash flow hedges to manage the variability in cash flows associated with intercompany debt balances.

As of December 31, 2021, on a pre-tax basis, $6 million is scheduled to be reclassified from Accumulated other comprehensive loss as an increase to interest expense over the next twelve months. Other Financial Instruments: Cash and Cash Equivalents —At December 31, 2021 and 2020, we had marketable securities classified as Cash and cash equivalents of $438 million and $682 million, respectively. Investments in Available-for-Sale Debt Securities— The following table summarizes the cost basis, gross unrealized gains and losses, and fair value of our outstanding available-for-sale debt securities: Millions of dollars Cost Gross Gross Fair Debt securities at December 31, 2021 $ — $ — $ — $ — Debt securities at December 31, 2020 348 1 — 349 No allowance for credit losses related to our investments in available-for-sale debt securities was recorded for the years ended December 31, 2021, 2020 and 2019.

Retirement Benefits [Abstract]
Pension and Other Postretirement Benefits [Text Block]	14. Pension and Other Post-retirement Benefits We have defined benefit pension plans which cover employees in the U.S. and various other countries. We also sponsor post-retirement benefit plans other than pensions that provide medical benefits to certain of our U.S., Canadian and French employees. In addition, we provide other post-employment benefits such as early retirement and deferred compensation severance benefits to employees of certain non-U.S. countries. We use a measurement date of December 31 for all of our benefit plans. Pension Benefits —The following tables provide a reconciliation of projected benefit obligations, plan assets and the funded status of our U.S. and non-U.S. defined benefit pension plans: Year Ended December 31, 2021 2020 Millions of dollars U.S. Non-U.S. U.S. Non-U.S. Change in benefit obligation: Benefit obligation, beginning of period $ 2,039 $ 2,159 $ 1,965 $ 2,017 Service cost 60 42 63 46 Interest cost 36 20 53 21 Actuarial loss (gain) (29) (107) 133 (21) Plan amendments — 1 — — Benefits paid (71) (50) (140) (47) Participant contributions — 2 — 2 Settlement (119) (8) (35) (11) Curtailment — — — (4) Foreign exchange effects — (135) — 156 Benefit obligation, end of period 1,916 1,924 2,039 2,159 Change in plan assets: Fair value of plan assets, beginning of period 1,548 1,168 1,637 1,058 Actual return on plan assets 229 (29) 76 26 Company contributions 156 62 10 64 Benefits paid (71) (50) (140) (47) Participant contributions — 2 — 2 Settlement (119) (8) (35) (11) Foreign exchange effects — (63) — 76 Fair value of plan assets, end of period 1,743 1,082 1,548 1,168 Funded status of continuing operations, end of period $ (173) $ (842) $ (491) $ (991) Amounts recognized in the Consolidated Balance Sheets consists of the following: December 31, 2021 December 31, 2020 Millions of dollars U.S. Non-U.S. U.S. Non-U.S. Prepaid benefit cost, long-term $ 7 $ 60 $ — $ 23 Accrued benefit liability, current — (31) — (33) Accrued benefit liability, long-term (180) (871) (491) (981) Funded status of continuing operations, end of period $ (173) $ (842) $ (491) $ (991) Amounts recognized in Accumulated other comprehensive loss include the following: December 31, 2021 December 31, 2020 Millions of dollars U.S. Non-U.S. U.S. Non-U.S. Actuarial and investment loss $ 450 $ 273 $ 655 $ 353 Prior service cost — 29 1 29 Balance, end of period $ 450 $ 302 $ 656 $ 382 The following additional information is presented for our U.S. and non-U.S. pension plans: December 31, 2021 December 31, 2020 Millions of dollars U.S. Non-U.S. U.S. Non-U.S. Accumulated benefit obligation for defined benefit plans $ 1,854 $ 1,783 $ 1,961 $ 2,003 Pension plans with projected benefit obligations in excess of the fair value of assets are summarized as follows: December 31, 2021 December 31, 2020 Millions of dollars U.S. Non-U.S. U.S. Non-U.S. Projected benefit obligations $ 1,909 $ 1,152 $ 1,899 $ 1,276 Fair value of assets 1,729 250 1,408 261 Pension plans with accumulated benefit obligations in excess of the fair value of assets are summarized as follows: December 31, 2021 December 31, 2020 Millions of dollars U.S. Non-U.S. U.S. Non-U.S. Accumulated benefit obligations $ 1,086 $ 1,005 $ 1,826 $ 1,123 Fair value of assets 966 215 1,408 231 Components of net periodic pension costs for our U.S. and non-U.S. plans are as follows: U.S. Plans Year Ended December 31, Millions of dollars 2021 2020 2019 Service cost $ 60 $ 63 $ 53 Interest cost 36 53 70 Expected return on plan assets (114) (115) (112) Settlement loss 27 4 — Actuarial loss amortization 35 29 18 Net periodic benefit cost $ 44 $ 34 $ 29 Non-U.S. Plans Year Ended December 31, Millions of dollars 2021 2020 2019 Service cost $ 42 $ 46 $ 36 Interest cost 20 21 33 Expected return on plan assets (17) (19) (24) Settlement loss 1 2 1 Curtailment gain — (4) — Prior service cost amortization 3 3 2 Actuarial loss amortization 15 23 12 Net periodic benefit cost $ 64 $ 72 $ 60 The actual and target asset allocations for our plans are as follows: 2021 2020 Actual Target Actual Target Canada Fixed income 100 % 100 % 100 % 100 % United Kingdom—Lyondell Chemical Plans Equity securities 39 % 38 % 37 % 37 % Fixed income 61 % 62 % 63 % 63 % United Kingdom—Basell Plans Equity securities 40 % 40 % 40 % 40 % Fixed income 60 % 60 % 60 % 60 % United Kingdom—A.

These assumptions vary for the different plans, as they are determined in consideration of local conditions. The weighted average assumptions used in determining the net benefit liabilities for our pension plans were as follows at December 31: 2021 2020 U.S. Non-U.S. U.S. Non-U.S. Discount rate 2.80 % 1.45 % 2.54 % 0.99 % Rate of compensation increase 4.74 % 2.64 % 4.63 % 2.55 % Cash balance interest credit rate 1.78 % — % 1.58 % — % The weighted average assumptions used in determining net benefit costs for our pension plans were as follows: Year Ended December 31, 2021 2020 2019 U.S. Non-U.S. U.S. Non-U.S. U.S. Non-U.S. Discount rate 2.54 % 0.99 % 3.16 % 1.03 % 4.51 % 2.07 % Expected return on plan assets 7.25 % 1.44 % 7.25 % 1.79 % 7.50 % 2.79 % Rate of compensation increase 4.63 % 2.55 % 4.83 % 2.59 % 4.83 % 2.54 % The discount rate assumptions reflect the rates at which the benefit obligations could be effectively settled, based on the yields of high quality long-term bonds where the term closely matches the term of the benefit obligations. We measure service and interest costs by applying the specific spot rates along that same yield curve to the projected cash flows of the plans. This approach provides a more precise measurement of service and interest costs. The weighted average expected long-term rate of return on assets in our U.S. plans of 7.25% is based on the average level of earnings that our independent pension investment adviser had advised could be expected to be earned over a fifteen to twenty year time period consistent with the target asset allocation of the plans, historical capital market performance, historical plan performance (since the 1997 inception of the U.S. Master Trust) and a forecast of expected future asset returns. The weighted average expected long-term rate of return on assets in our non-U.S. plans of 1.44% is based on expectations and asset allocations that vary by region. We review these long-term assumptions on a periodic basis. Actual rates of return may differ from the expected rate due to the volatility normally experienced in capital markets. Assets are externally managed by professional investment firms over the long term to achieve optimal returns with an acceptable level of risk and volatility in order to meet the benefit obligations of the plans as they come due. Our pension plans have not directly invested in securities of LyondellBasell N.V., and there have been no significant transactions between any of the pension plans and the Company or related parties thereof. The pension investments that are measured at fair value are summarized below: December 31, 2021 Millions of dollars Fair Value Level 1 Level 2 Level 3 U.S. Common and preferred stock $ 279 $ 279 $ — $ — Commingled funds measured at net asset value 523 Real estate measured at net asset value 113 Hedge funds measured at net asset value 171 Private equity measured at net asset value 203 U.S. government securities 401 401 — — Cash and cash equivalents 64 64 — — Total U.S. Pension Assets $ 1,754 $ 744 $ — $ — December 31, 2021 Millions of dollars Fair Value Level 1 Level 2 Level 3 Non-U.S. Insurance arrangements $ 737 $ — $ — $ 737 Commingled funds measured at net asset value 341 Cash and cash equivalents 2 2 — — Total Non-U.S. Pension Assets $ 1,080 $ 2 $ — $ 737 December 31, 2020 Millions of dollars Fair Value Level 1 Level 2 Level 3 U.S. Common and preferred stock $ 281 $ 281 $ — $ — Commingled funds measured at net asset value 555 Real estate measured at net asset value 100 Hedge funds measured at net asset value 114 Private equity measured at net asset value 137 U.S. government securities 339 339 — — Cash and cash equivalents 43 43 — — Total U.S. Pension Assets $ 1,569 $ 663 $ — $ — December 31, 2020 Millions of dollars Fair Value Level 1 Level 2 Level 3 Non-U.S. Insurance arrangements $ 825 $ — $ — $ 825 Commingled funds measured at net asset value 339 Cash and cash equivalents 2 2 — — Total Non-U.S. Pension Assets $ 1,166 $ 2 $ — $ 825 Certain non-U.S. plans have investments in a pooled asset portfolio which are treated as a nonparticipating insurance contract. The associated plan assets underlying the insurance arrangement are measured at the cash surrender value, which is derived primarily from an actuarial determination of the discounted benefits cash flows. As such, these assets are considered as using significant unobservable inputs (Level 3). These defined benefits pension plan assets at December 31, 2020 were valued at $825 million and has decreased to $737 million at December 31, 2021. The change is due primarily to the depreciation of assets as well as an increase of the discount rate from 2020 to 2021. The fair value measurements of the investments in certain entities that calculate net asset value per share as of December 31, 2021 are as follows: Millions of dollars Fair Unfunded Remaining Redemption Frequency Trade to Redemption U.S. Commingled fund investing in Domestic Equity $ 148 $ — N/A daily 1 to 3 days 3 to 4 days Commingled fund investing in International Equity 128 — N/A daily 1 to 3 days 3 days Commingled fund investing in Fixed Income 247 — N/A daily 1 to 3 days 3 to 7 days Real Estate 113 14 10 years quarterly 15 to 25 days 45 to 90 days Hedge Funds 171 — N/A quarterly 10 to 30 days 20 to 90 days Private Equity 203 72 10 years Not eligible N/A N/A Total U.S. $ 1,010 $ 86 Millions of dollars Fair Unfunded Remaining Redemption Frequency Trade to Redemption Non-U.S. Commingled fund investing in Domestic Equity $ 35 $ — N/A 1 to 7 days 1 to 3 days 1 to 3 days Commingled fund investing in International Equity 67 — N/A 1 to 7 days 1 to 3 days 1 to 3 days Commingled fund investing in Fixed Income 239 — N/A daily 1 to 3 days 3 days Total Non-U.S. $ 341 $ — The fair value measurements of the investments in certain entities that calculate net asset value per share as of December 31, 2020 are as follows: Millions of dollars Fair Unfunded Remaining Redemption Frequency Trade to Redemption U.S. Commingled fund investing in Domestic Equity $ 179 $ — N/A daily 1 to 3 days 3 to 4 days Commingled fund investing in International Equity 118 — N/A daily 1 to 3 days 3 days Commingled fund investing in Fixed Income 258 — N/A daily 1 to 3 days 3 to 7 days Real Estate 100 19 10 years quarterly 15 to 25 days 45 to 90 days Hedge Funds 114 — N/A quarterly 10 to 30 days 20 to 90 days Private Equity 137 79 10 years Not eligible N/A N/A Total U.S. $ 906 $ 98 Millions of dollars Fair Unfunded Remaining Redemption Frequency Trade to Redemption Non-U.S. Commingled fund investing in Domestic Equity $ 24 $ — N/A 1 to 7 days 1 to 3 days 1 to 3 days Commingled fund investing in International Equity 68 — N/A 1 to 7 days 1 to 3 days 1 to 3 days Commingled fund investing in Fixed Income 247 — N/A daily 1 to 3 days 3 days Total Non-U.S. $ 339 $ — Multi-employer Plan —The Company participates in a multi-employer arrangement with Pensionskasse der BASF WaG V.VaG (“Pensionskasse”) which provides for benefits to the majority of our employees in Germany. Up to a certain salary level, the benefit obligations are covered by contributions of the Company and the employees to the plan. Contributions made to the multi-employer plan are expensed as incurred. The following table provides disclosure related to the Company’s multi-employer plan: Company Contributions Millions of dollars 2021 2020 2019 Pensionskasse $ 6 $ 7 $ 8 The Company-specific plan information for the Pensionskasse is not publicly available and the plan is not subject to a collective-bargaining agreement. The plan provides fixed, monthly retirement payments on the basis of the credits earned by the participating employees. To the extent that the Pensionskasse is underfunded, the future contributions to the plan may increase and may be used to fund retirement benefits for employees related to other employers. The Pensionskasse financial statements for the years ended December 31, 2020 and 2019 indicated total assets of $10,257 million and $10,712 million, respectively; total actuarial present value of accumulated plan benefits of $9,828 million and $10,259 million, respectively; and total contributions for all participating employers of $254 million and $260 million, respectively. Our plan contributions did not exceed 5 percent of the total contributions in 2021, 2020 or 2019. Other Post-retirement Benefits —We sponsor unfunded health care and life insurance plans covering certain eligible retired employees and their eligible dependents. Generally, the medical plans pay a stated percentage of medical expenses reduced by deductibles and other coverage. Life insurance benefits are generally provided by insurance contracts.

Deferred income taxes related to amounts in Accumulated other comprehensive loss include provisions of $178 million and $246 million as of December 31, 2021 and 2020, respectively. Defined Contribution Plans —Most employees in the U.S. and certain non-U.S. countries are eligible to participate in defined contribution plans (“Employee Savings Plan”) by contributing a portion of their compensation. We make employer contributions, such as matching contributions, to certain of these plans. The Company also has a nonqualified deferred compensation plan that covers senior management in the U.S. This plan was amended in April 2013 to provide for Company contributions on behalf of certain eligible employees who earn base pay above the IRS annual compensation limit.

Share-based Payment Arrangement [Abstract]
Incentive and Share-Based Compensation [Text Block]	15. Incentive and Share-Based Compensation We are authorized to grant restricted stock units, stock options, performance share units, and other cash and stock awards under our Long-Term Incentive Plan (“LTIP”). The Compensation and Talent Development Committee oversees our equity award grants, the type of awards, the required performance measures and the timing and duration of each grant. The maximum number of shares of our common stock reserved for issuance under the LTIP is 30,000,000 shares. As of December 31, 2021, there were 10,068,676 shares remaining available for issuance assuming maximum payout for performance share units awards. Our share-based compensation awards, which are subject to customary partial or accelerated vesting or forfeiture in the event of certain termination events, are accounted for as equity awards with compensation cost recognized over the vesting period in the income statement. We use a straight-line vesting method for cliff-vested awards and a graded vesting method for step-vested awards. We have elected to recognize forfeitures as they occur for stock-based compensation. When options are exercised and awards are paid out, shares are issued from our treasury shares. Total share-based compensation expense and the associated tax benefits are as follows: Year Ended December 31, Millions of dollars 2021 2020 2019 Compensation Expense: Restricted stock units $ 30 $ 26 $ 21 Stock options 9 8 7 Performance share units 27 21 20 Total $ 66 $ 55 $ 48 Tax Benefit: Restricted stock units $ 7 $ 6 $ 5 Stock options 2 2 2 Performance share units 6 5 4 Total $ 15 $ 13 $ 11 Restricted Stock Unit Awards (“RSUs”) —RSUs entitle the recipient to be paid out an equal number of ordinary shares upon vesting. RSUs generally cliff vest on the third anniversary of the grant date. The holders of RSUs are entitled to nonforfeitable dividend equivalents settled in the form of cash payments, which are recognized as dividends in Retained earnings. The fair value of RSUs is based on the market price of the underlying stock on the date of grant. The weighted average grant date fair value for RSUs granted during the years ended December 31, 2021, 2020 and 2019 was $104.43, $79.58 and $87.36, respectively. The total fair value of RSUs vested was $27 million, $18 million and $13 million during 2021, 2020 and 2019, respectively. The following table summarizes RSU activity: Number of Weighted Average Outstanding at January 1, 2021 693 $ 88.45 Granted 390 104.43 Vested (270) 96.29 Forfeited (75) 94.38 Outstanding at December 31, 2021 738 $ 93.43 As of December 31, 2021, the unrecognized compensation cost related to RSUs was $29 million, which is expected to be recognized over a weighted average period of two years. Stock Option Awards (“Stock Options”) —Stock Options allow employees the opportunity in the future to purchase ordinary shares of stock at an exercise price equal to the market price at the date of grant. The awards generally have a three-year vesting period that vests in equal increments on the first, second and third anniversary of the grant date and have a contractual term of ten years. None of the Stock Options are designed to qualify as incentive Stock Options as defined in Section 422 of the Internal Revenue Code. The fair value of each Stock Option is estimated, based on several assumptions, on the date of grant using the Black-Scholes option valuation model. The principal assumptions utilized in valuing Stock Options include the expected stock price volatility (based on our historical stock price volatility over the expected term); the expected dividend yield; and the risk-free interest rate (an estimate based on the yield of a United States Treasury zero coupon bond with a maturity equal to the expected term of the option). The expected term of Stock Options granted in 2021 is estimated based on the weighted average of historical exercise patterns and the midpoint of the remaining expected life. Prior to 2021, the expected term of Stock Options granted was estimated based on a simplified approach, which was consistent with the historical exercise pattern. The weighted average fair value of Stock Options granted and the assumptions used in estimating those fair value are as follows: Year Ended December 31, 2021 2020 2019 Weighted average fair value $ 20.49 $ 12.18 $ 15.76 Fair value assumptions: Dividend yield 5.9 % 5.0 % 4.2 % Expected volatility 39.1-39.4% 28.3-38.4% 27.2-28.1% Risk-free interest rate 0.9-1.0% 0.3-1.4% 1.5-2.6% Weighted average expected term, in years 5.6 6.0 6.0 The following table summarizes Stock Option activity: Number of Weighted Weighted Aggregate Outstanding at January 1, 2021 2,404 $ 88.36 Granted 537 104.48 Exercised (356) 87.83 Forfeited (135) 96.89 Expired (1) 103.71 Outstanding at December 31, 2021 2,449 $ 91.50 7.4 years $ 13 Exercisable at December 31, 2021 1,741 $ 90.14 5.4 years $ 10 The aggregate intrinsic value of Stock Options exercised during the years ended December 31, 2021, 2020 and 2019 was $7 million, $1 million and less than $1 million, respectively. As of December 31, 2021, the unrecognized compensation cost related to Stock Options was $5 million, which is expected to be recognized over one year. During 2021, cash received from the exercise of Stock Options was $24 million and the tax benefit associated with these exercises was $2 million. Performance Share Units Awards (“PSUs”) —A target number of PSUs is granted to participants at the beginning of a three-year performance period. Final payout of awards, which can range from 0% to 200% of target shares granted, is determined and paid after the performance period. These awards are settled in shares of common stock, and each unit is equivalent to one share of our common stock. The payout for PSUs granted after February 2021 will be equally based on Total Shareholder Return (“TSR”) relative to our peers and a performance metric. The fair value of the portion of the award that vests based on TSR is estimated using a Monte-Carlo simulation. For the other portion of the award, the fair value is determined based on our stock price and the number of target shares expected to vest at the end of each reporting period. Prior to 2021, all our PSUs vesting was based on TSR relative to our peers, and the fair value was estimated using a Monte-Carlo simulation. Outstanding PSUs accrue dividend equivalent units, which will be converted to shares upon payment at the end of the performance period and are classified as Accrued liabilities and Other liabilities on the Consolidated Balance Sheets. Dividend equivalents for PSUs are recorded in Retained earnings. The weighted average fair value and the assumptions used in estimating those fair value using a Monte-Carlo simulation are as follows: Year Ended December 31, 2021 2020 2019 Weighted average fair value $ 169.57 $ 82.70 $ 76.35 Fair value assumptions: Expected volatility of LyondellBasell N.V. common stock 48.05 % 25.96-41.50% 24.11 % Expected volatility of peer companies 24.30-59.44% 16.13-50.42% 14.57-40.55% Average correlation coefficient of peer companies 0.59 0.45-0.58 0.50 Risk-free interest rate 0.31 % 0.23-1.35% 2.48 % The following table summarizes PSU activity assuming payout at 100% of target shares: Number of Weighted Average Outstanding at January 1, 2021 749 $ 82.07 Granted 288 130.85 Vested — — Forfeited (283) 95.99 Outstanding at December 31, 2021 754 $ 95.45 The total fair value of PSUs vested during 2020 and 2019 was $9 million and $22 million, respectively. As of December 31, 2021, the unrecognized compensation cost related to PSUs was $25 million, which is expected to be recognized over a weighted average period of two years. Employee Stock Purchase Plan —We have an Employee Share Purchase Plan (“ESPP”) which allows participants to purchase our stock at a 10% discount on the lower of the fair market value at either the beginning or end of the purchase period. As a result of the 10% discount and the look-back provision, the ESPP is considered a compensatory plan under generally accepted accounting principles. Total expense related to our ESPP for 2021, 2020 and 2019 was $3 million, $4 million and $2 million, respectively.

Income Tax Disclosure [Abstract]
Income Taxes [Text Block]	16. Income Taxes LyondellBasell Industries N.V. is tax resident in the United Kingdom pursuant to a mutual agreement procedure determination ruling between the Dutch and United Kingdom competent authorities and therefore subject solely to the United Kingdom corporate income tax system. LyondellBasell Industries N.V. has little or no taxable income of its own because, as a holding company, it does not conduct any operations. Through our subsidiaries, we have substantial operations world-wide. Taxes are paid on the earnings generated in various jurisdictions where our subsidiaries operate, including primarily the U.S., The Netherlands, Germany, France, and Italy. The Company operates in multiple jurisdictions with complex legal and tax regulatory environments and our tax returns are periodically audited or subjected to review by tax authorities. We monitor tax law changes and the potential impact to our results of operations. There continues to be increased attention to the tax practices of multinational companies, including U.S tax reform proposals, European Union’s state aid investigations, Pillar One and Two proposals by the Organization for Economic Cooperation and Development (“OECD”) with respect to base erosion and profit shifting, and European Union tax directives and their implementation. Although certain actions have occurred, there continues to be uncertainty as to the enactment and implementation of U.S. tax reform proposals and the OECD’s Pillars One and Two. Management continues to monitor these and other proposed tax law changes as they could increase our tax liabilities in the future, if enacted. The Company considered the impact of the CARES Act, enacted March 27, 2020, in the period of enactment. Several of the tax measures favorably impacted our income tax provision in 2020. Based on return filings in 2021, we recorded an overall tax benefit related to the carryback of U.S. tax net operating losses (“NOL”) of approximately $300 million and $64 million in 2020 and 2021, respectively. Our anticipated refund increased from last year after the return filing and we have received approximately $870 million and $100 million of an anticipated $1.1 billion cash refund in the fourth quarter of 2021 and first quarter of 2022, respectively. We anticipate the remaining refund to be received in 2022. The significant components of the provision for income taxes are as follows: Year Ended December 31, Millions of dollars 2021 2020 2019 Current: U.S. federal $ 669 $ (774) $ 122 Non-U.S. 617 399 296 State 75 1 21 Total current 1,361 (374) 439 Deferred: U.S. federal (103) 415 124 Non-U.S. (114) (76) 75 State 19 (8) 10 Total deferred (198) 331 209 Provision for (benefit from) income taxes before tax effects of other comprehensive income 1,163 (43) 648 Tax effects of elements of other comprehensive income: Pension and post-retirement liabilities 67 (10) (92) Financial derivatives 20 (70) (38) Foreign currency translation 45 (30) 8 Total income tax expense (benefit) in other comprehensive income $ 1,295 $ (153) $ 526 Since the proportion of U.S. revenues, assets, operating income and associated tax provisions is significantly greater than any other single taxing jurisdiction within the worldwide group, the reconciliation of the differences between the provision for income taxes and the statutory rate is presented on the basis of the U.S. statutory federal income tax rate of 21% as opposed to the United Kingdom statutory rate of 19%. Our effective tax rate for the year ended December 31, 2021 is 17.1%. Our effective income tax rate fluctuates based on, among other factors, changes in pre-tax income in countries with varying statutory tax rates, changes in valuation allowances, changes in foreign exchange gains/losses, the amount of exempt income, changes in unrecognized tax benefits associated with uncertain tax positions and changes in tax laws. The following table reconciles the expected tax expense (benefit) at the U.S. statutory federal income tax rate to the total income tax provision as calculated: Year Ended December 31, Millions of dollars 2021 2020 2019 Income (loss) before income taxes: U.S. $ 3,458 $ (456) $ 1,581 Non-U.S. 3,328 1,842 2,471 Total $ 6,786 $ 1,386 $ 4,052 Income tax at U.S. statutory rate $ 1,425 $ 291 $ 851 Increase (reduction) resulting from: Non-U.S. income taxed at different statutory rates 73 14 64 Changes in tax laws (6) (298) 1 Return to accrual adjustments (179) (50) 9 State income taxes, net of federal benefit 82 (2) 29 Exempt income (303) (144) (182) Liquidation loss — — (51) Patent box ruling — — (65) Uncertain tax positions 19 97 (42) Other, net 52 49 34 Income tax provision $ 1,163 $ (43) $ 648 Our return to accrual adjustments primarily include the tax benefits associated with an election made in 2021 to step-up of certain Italian assets to fair market value retroactively and the impact of certain retroactive elections made with respect to the CARES Act in the U.S. Our exempt income primarily includes interest income, export incentives, and equity earnings of joint ventures. Interest income earned by certain of our European subsidiaries through intercompany financings is taxed at rates substantially lower than the U.S. statutory rate. Export incentives relate to tax benefits derived from elections and structures available for U.S. exports. Equity earnings attributable to the earnings of our joint ventures, when paid through dividends to certain European subsidiaries, are exempt from all or portions of normal statutory income tax rates. We currently anticipate the favorable treatment for interest income, dividends, and export incentives to continue in the near term; however, this treatment is based on current law and tax rulings, which could change if the tax reform proposals in the U.S. and the Pillar Two proposals by the OECD are enacted. The deferred tax effects of tax loss, credit and interest carryforwards (“tax attributes”) and the tax effects of temporary differences between the tax basis of assets and liabilities and their reported amounts in the Consolidated Financial Statements, reduced by a valuation allowance where appropriate, are presented below. December 31, Millions of dollars 2021 2020 Deferred tax liabilities: Accelerated tax depreciation $ 1,838 $ 1,992 Investment in joint venture partnerships 525 532 Intangible assets 39 75 Inventory 192 323 Operating lease assets 423 335 Other liabilities 103 89 Total deferred tax liabilities $ 3,120 $ 3,346 Deferred tax assets: Tax attributes $ 182 $ 242 Employee benefit plans 339 426 Operating lease liabilities 429 341 Other assets 136 176 Total deferred tax assets 1,086 1,185 Deferred tax asset valuation allowances (126) (132) Net deferred tax assets 960 1,053 Net deferred tax liabilities $ 2,160 $ 2,293 December 31, Millions of dollars 2021 2020 Balance sheet classifications: Deferred tax assets—long-term $ 174 $ 39 Deferred tax liabilities—long-term 2,334 2,332 Net deferred tax liabilities $ 2,160 $ 2,293 Deferred taxes on the unremitted earnings of certain equity joint ventures and subsidiaries of $94 million and $89 million at December 31, 2021 and 2020, respectively, have been provided. The Company intends to permanently reinvest approximately $550 million of our non-U.S. earnings. Repatriation of these earnings to the U.S. in the future could result in a tax impact of approximately $60 million. At December 31, 2021 and 2020, we had total tax attributes available in the amount of $943 million and $1,221 million, respectively, for which a deferred tax asset was recognized at December 31, 2021 and 2020 of $182 million and $242 million, respectively. The scheduled expiration of the tax attributes and the related deferred tax assets, before valuation allowance, as of December 31, 2021 are as follows: Millions of dollars Tax Deferred Tax 2022 $ 26 $ 1 2023 8 — 2024 31 1 2025 18 1 2026 3 1 Thereafter 301 25 Indefinite 556 153 Total $ 943 $ 182 The tax attributes are primarily related to operations in The Netherlands, France, United Kingdom and United States. The related deferred tax assets by primary jurisdictions are shown below: December 31, Millions of dollars 2021 2020 2019 The Netherlands $ 81 $ 103 $ 4 United Kingdom 31 30 36 France 26 58 30 United States 25 25 68 Spain — 6 8 Other 19 20 22 Total $ 182 $ 242 $ 168 To fully realize these net deferred tax assets, we will need to generate sufficient future taxable income in the countries where these tax attributes exist during the periods in which the attributes can be utilized. Based upon projections of future taxable income over the periods in which the attributes can be utilized and/or temporary differences are expected to reverse, management believes it is more likely than not that $56 million of these deferred tax assets at December 31, 2021 will be realized. As of each reporting date, management considers the weight of all evidence, both positive and negative, to determine if a valuation allowance is necessary for each jurisdictions’ net deferred tax assets. We place greater weight on historical evidence over future predictions of our ability to utilize net deferred tax assets. We consider future reversals of existing taxable temporary differences, future taxable income exclusive of reversing temporary differences, and taxable income in prior carryback year(s) if carryback is permitted under applicable law, as well as available prudent and feasible tax planning strategies that would, if necessary, be implemented to ensure realization of the net deferred tax asset. A summary of the valuation allowances by primary jurisdiction is shown below, reflecting the valuation allowances for all the net deferred tax assets, including deferred tax assets for tax attributes and other temporary differences. December 31, Millions of dollars 2021 2020 2019 The Netherlands $ 55 $ 57 $ 3 United Kingdom 31 30 36 France 26 26 23 United States 12 14 13 Other 2 5 10 $ 126 $ 132 $ 85 During 2020, the valuation allowance in The Netherlands increased with respect to tax attributes for which we do not expect we can realize the benefit in the foreseeable future or before expiration. Tax benefits totaling $327 million, $339 million and $238 million relating to uncertain tax positions were unrecognized as of December 31, 2021, 2020 and 2019, respectively. The following table presents a reconciliation of the beginning and ending amounts of unrecognized tax benefits: Year Ended December 31, Millions of dollars 2021 2020 2019 Balance, beginning of period $ 339 $ 238 $ 269 Additions for tax positions of current year — 1 49 Additions for tax positions of prior years 20 113 20 Reductions for tax positions of prior years (21) (12) (100) Settlements (payments/refunds) (11) (1) — Balance, end of period $ 327 $ 339 $ 238 The majority of the uncertain tax positions, if recognized, will affect the effective tax rate. We operate in multiple jurisdictions throughout the world, and our tax returns are periodically audited or subjected to review by tax authorities. We are currently under examination in a number of tax jurisdictions. As a result, there is an uncertainty in income taxes recognized in our financial statements. Positions challenged by the tax authorities may be settled or appealed by us. During 2020, we accrued a $113 million non-cash tax expense to our effective tax rate as an addition for tax positions of prior years. During 2019, we recognized a $113 million non-cash benefit to our effective tax rate consisting of $100 million of previously unrecognized tax benefits as a reduction for tax positions of a prior year and the release of $13 million of previously accrued interest. These benefits were largely due to the expiration of certain statutes of limitations. These non-cash reductions in unrecognized tax benefits are reflected on our Consolidated Balance Sheets in Other liabilities and on our Consolidated Statements of Cash Flows in Other operating activities. We are no longer subject to any significant income tax examinations by tax authorities for the years prior to 2018 in The Netherlands, prior to 2014 in Italy, prior to 2005 in Germany, prior to 2019 in France, prior to 2016 in the United Kingdom, and prior to 2014 in the U.S., our principal tax jurisdictions. It is reasonably possible that, within the next twelve months, due to the settlement of uncertain tax positions with various tax authorities and the expiration of statutes of limitations, unrecognized tax benefits could decrease by up to approximately $100 million. We recognize interest associated with unrecognized tax benefits in income tax expense. Income tax expense includes an expense of interest and penalties of $25 million in 2021, an expense of interest and penalties of $1 million in 2020, and a benefit of interest and penalties of $1 million in 2019. We had accrued approximately $40 million, $16 million and $15 million for interest and penalties as of December 31, 2021, 2020 and 2019, respectively.

Commitments and Contingencies

Commitments and Contingencies	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies [Text Block]	17. Commitments and Contingencies Commitments —We have various purchase commitments for materials, supplies and services incidental to the ordinary conduct of business, generally for quantities required for our businesses and at prevailing market prices. These commitments are designed to assure sources of supply and are not expected to be in excess of normal requirements. As of December 31, 2021, we had capital expenditure commitments, which we incurred in our normal course of business, including commitments of approximately $276 million related to building our new PO/TBA plant in Houston, Texas. Financial Assurance Instruments —We have obtained letters of credit, performance and surety bonds and have issued financial and performance guarantees to support trade payables, potential liabilities and other obligations. Considering the frequency of claims made against the financial instruments we use to support our obligations, and the magnitude of those financial instruments in light of our current financial position, management does not expect that any claims against or draws on these instruments would have a material adverse effect on our Consolidated Financial Statements. We have not experienced any unmanageable difficulties in obtaining the required financial assurance instruments for our current operations. Environmental Remediation —Our accrued liability for future environmental remediation costs at current and former plant sites and other remediation sites totaled $138 million and $133 million as of December 31, 2021 and 2020, respectively. At December 31, 2021, the accrued liabilities for individual sites range from less than $1 million to $27 million. The remediation expenditures are expected to occur over a number of years, and not concentrated in any single year. In our opinion, it is reasonably possible that losses in excess of the liabilities recorded may have been incurred. However, we cannot estimate any amount or range of such possible additional losses. New information about sites, new technology or future developments such as involvement in investigations by regulatory agencies, could require us to reassess our potential exposure related to environmental matters. The following table summarizes the activity in our accrued environmental liability included in “Accrued liabilities” and “Other liabilities:” Year Ended December 31, Millions of dollars 2021 2020 Beginning balance $ 133 $ 132 Changes in estimates 25 3 Amounts paid (14) (8) Foreign exchange effects (5) 6 Other (1) — Ending balance $ 138 $ 133 Indemnification —We are parties to various indemnification arrangements, including arrangements entered into in connection with acquisitions, divestitures and the formation and dissolution of joint ventures. Pursuant to these arrangements, we provide indemnification to and/or receive indemnification from other parties in connection with liabilities that may arise in connection with the transactions and in connection with activities prior to completion of the transactions. These indemnification arrangements typically include provisions pertaining to third party claims relating to environmental and tax matters and various types of litigation. As of December 31, 2021, we had not accrued any significant amounts for our indemnification obligations, and we are not aware of other circumstances that would likely lead to significant future indemnification obligations. We cannot determine with certainty the potential amount of future payments under the indemnification arrangements until events arise that would trigger a liability under the arrangements. As part of our technology licensing contracts, we give indemnifications to our licensees for liabilities arising from possible patent infringement claims with respect to certain proprietary licensed technologies. Such indemnifications have a stated maximum amount and generally cover a period of 5 to 10 years. Legal Proceedings— We are subject to various lawsuits and claims, including but not limited to, matters involving contract disputes, environmental damages, personal injury and property damage. We vigorously defend ourselves and prosecute these matters as appropriate. Our legal organization applies its knowledge, experience and professional judgment to the specific characteristics of our cases, employing a litigation management process to manage and monitor legal proceedings in which we are a party. Our process facilitates the early evaluation and quantification of potential exposures in individual cases. This process also enables us to track those cases that have been scheduled for trial, mediation or other resolution. We regularly assess the adequacy of legal accruals based on our professional judgment, experience and the information available regarding our cases. Based on a consideration of all relevant facts and circumstances, we do not believe the ultimate outcome of any currently pending lawsuit against us will have a material adverse effect upon our operations, financial condition or Consolidated Financial Statements.

Segment Reporting [Abstract]
Segment and Related Information [Text Block]	20. Segment and Related Information Our operations are managed by senior executives who report to our Chief Executive Officer, the chief operating decision maker. Discrete financial information is available for each of the segments, and our Chief Executive Officer uses the operating results of each of the operating segments for performance evaluation and resource allocation. The activities of each of our segments from which they earn revenues and incur expenses are described below: • Olefins and Polyolefins — Americas (“O&P—Americas”). Our O&P—Americas segment produces and markets olefins and co-products, polyethylene and polypropylene. • Olefins and Polyolefins — Europe, Asia, International (“O&P—EAI”). Our O&P—EAI segment produces and markets olefins and co-products, polyethylene, and polypropylene. • Intermediates and Derivatives (“I&D”). Our I&D segment produces and markets propylene oxide and its derivatives; oxyfuels and related products; and intermediate chemicals such as styrene monomer, acetyls, ethylene oxide and ethylene glycol. • Advanced Polymer Solutions (“APS”) . Our APS segment produces and markets compounding and solutions, such as polypropylene compounds, engineered plastics, masterbatches, engineered composites, colors and powders, and advanced polymers, which includes Catalloy and polybutene-1. • Refining . Our Refining segment refines heavy, high-sulfur crude oil and other crude oils of varied types and sources available on the U.S. Gulf Coast into refined products, including gasoline and distillates. • Technology . Our Technology segment develops and licenses chemical and polyolefin process technologies and manufactures and sells polyolefin catalysts. Our chief operating decision maker uses EBITDA as the primary measure for reviewing profitability of our segments, and therefore, we have presented EBITDA for all segments. We define EBITDA as earnings from continuing operations before interest, income taxes, and depreciation and amortization. “Other” includes intersegment eliminations and items that are not directly related or allocated to business operations, such as foreign exchange gains or losses and components of pension and other post-retirement benefit costs other than service costs. Sales between segments are made primarily at prices approximating prevailing market prices. Summarized financial information concerning reportable segments is shown in the following tables for the periods presented: Year Ended December 31, 2021 O&P – O&P – I&D APS Refining Technology Other Total Millions of dollars Sales and other operating revenues: Customers $ 10,502 $ 12,685 $ 9,968 $ 5,133 $ 7,178 $ 707 $ — $ 46,173 Intersegment 4,500 805 212 12 824 136 (6,489) — 15,002 13,490 10,180 5,145 8,002 843 (6,489) 46,173 Depreciation and amortization expense 578 197 379 117 79 43 — 1,393 Other income (expense), net 28 11 (2) 7 (7) — 25 62 Income (loss) from equity investments 115 313 34 (1) — — — 461 EBITDA 5,273 1,749 1,378 409 (624) 514 (10) 8,689 Capital expenditures 319 249 1,112 85 74 91 29 1,959 Year Ended December 31, 2020 Millions of dollars O&P – O&P – I&D APS Refining Technology Other Total Sales and other operating revenues: Customers $ 5,032 $ 7,809 $ 6,144 $ 3,903 $ 4,346 $ 519 $ — $ 27,753 Intersegment 2,243 558 125 10 381 140 (3,457) — 7,275 8,367 6,269 3,913 4,727 659 (3,457) 27,753 Depreciation and amortization expense 525 214 305 152 152 37 — 1,385 Other income (expense), net 70 14 1 1 1 — (2) 85 Income (loss) from equity investments 45 186 26 (1) — — — 256 EBITDA 1,810 826 833 378 (871) 324 (15) 3,285 Capital expenditures 543 166 880 63 63 111 121 1,947 Year Ended December 31, 2019 Millions of dollars O&P – O&P – I&D APS Refining Technology Other Total Sales and other operating revenues: Customers $ 5,311 $ 8,764 $ 7,642 $ 4,846 $ 7,599 $ 565 $ — $ 34,727 Intersegment 3,124 740 192 4 652 98 (4,810) — 8,435 9,504 7,834 4,850 8,251 663 (4,810) 34,727 Depreciation and amortization expense 470 208 295 133 169 37 — 1,312 Other income, net 9 9 6 1 6 — 8 39 Income from equity investments 46 172 7 — — — — 225 EBITDA 2,302 1,062 1,557 424 (65) 411 1 5,692 Capital expenditures 1,099 213 1,064 59 149 94 16 2,694 Operating results for our APS segment include integration costs of $37 million and $116 million in 2020 and 2019, respectively, associated with our acquisition of A.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Basis of preparation and consolidation [Policy Text Block]	Basis of Preparation and Consolidation The accompanying Consolidated Financial Statements have been prepared from the books and records of LyondellBasell N.V. under accounting principles generally accepted in the United States (“U.S. GAAP”). Subsidiaries are defined as being those companies over which we, either directly or indirectly, have control through a majority of the voting rights or the right to exercise control or to obtain the majority of the benefits and be exposed to the majority of the risks. Subsidiaries are consolidated from the date on which control is obtained until the date that such control ceases. All intercompany transactions and balances have been eliminated in consolidation.
Cash and cash equivalents [Policy Text Block]	Cash and Cash Equivalents Our cash equivalents consist of highly liquid debt instruments such as certificates of deposit, commercial paper and money market accounts with major international banks and financial institutions. Cash equivalents include instruments with maturities of three months or less when acquired and exclude restricted cash.
Short-term investments [Policy Text Block]	Short-Term Investments Our investments in debt securities are classified as available-for-sale and held-to-maturity on the basis of our intent and ability to hold the investments. Investments classified as available-for-sale are carried at fair value with changes reflected in other comprehensive income. Credit-related impairment, measured using the expected cash flows and limited to the amount by which the amortized cost basis of a security exceeds its fair value, is recognized through an allowance for expected credit losses, and adjusted subsequently if conditions change, with a corresponding impact in earnings. Where there is an intention or a requirement to sell an impaired available-for-sale debt security, the entire impairment is recognized in earnings with a corresponding adjustment to the amortized cost basis of the security.
Trade receivables [Policy Text Block]	Trade Receivables Trade receivables are amounts due from customers for merchandise sold or services performed in the ordinary course of business and are carried at transaction price net of allowance for credit losses. Allowance for credit losses is measured using historical loss rates for the respective risk categories and incorporating forward-looking estimates. The corresponding expense for the loss allowance is reflected in Selling, general and administrative expenses.
Inventories [Policy Text Block]	Inventories Cost of our raw materials, work-in-progress and finished goods inventories is determined using the last-in, first-out (“LIFO”) method and is carried at the lower of cost or market value. Cost of our materials and supplies inventory is determined using the moving average cost method and is carried at the lower of cost and net realizable value.
Property, plant and equipment [Policy Text Block]	Property, Plant and Equipment Property, plant and equipment are recorded at historical cost. Historical cost includes expenditures that are directly attributable to the acquisition of the items. Costs may also include borrowing costs incurred on debt during construction of major projects exceeding one year, costs of major maintenance arising from turnarounds of major units and legally obligated decommissioning costs. Routine maintenance costs are expensed as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of assets to their residual values. The residual values and useful lives of assets are reviewed, and adjusted if appropriate, whenever events or circumstances indicate that a revision is warranted. Land is not depreciated. We evaluate property, plant and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Long-lived assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets, which, for us, is generally at the plant group level (or, at times, individual plants in certain circumstances where we have isolated production units with separately identifiable cash flows). If it is determined that an asset or asset group’s carrying value exceeded its undiscounted estimated pre-tax cash flows and estimated fair value, the asset is written down to its estimated fair value. Gain or loss on retirement or sale of property, plant and equipment is recognized in Other income (expense), net.
Equity investments [Policy Text Block]	Equity Investments We account for equity method investments (“equity investments”) using the equity method of accounting if we have the ability to exercise significant influence over, but not control of, an investee. Significant influence generally exists if we have an ownership interest representing between 20% and 50% of the voting rights. Under the equity method of accounting, investments are stated initially at cost and are adjusted for subsequent additional investments and our proportionate share of profit or losses and distributions. We record our share of the profits or losses of the equity investments, net of income taxes, in the Consolidated Statements of Income. When our share of losses in an equity investment equals or exceeds the carrying amount of our investment including advances made by us, we do not recognize further losses, unless we have guaranteed obligations or are otherwise committed to provide further financial support to the investee. We assess our equity investments for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment may not be recoverable. If the decline in value is considered to be other-than-temporary, the investment is written down to its estimated fair value. Investments in PO Joint Ventures and the Louisiana Joint Venture —We share ownership with Covestro PO LLC, a subsidiary of Covestro AG (collectively “Covestro”), in a U.S. propylene oxide (“PO”) manufacturing joint venture (the “U.S. PO Joint Venture”). The U.S. PO Joint Venture owns a PO/styrene monomer (“SM” or “styrene”) and a PO/tertiary butyl alcohol (“TBA”) manufacturing facility. Covestro’s ownership interest in Series A partnership units represents an undivided interest in certain U.S. PO Joint Venture assets with correlative PO capacity reservation that resulted in ownership of annual in-kind cost-based PO production of approximately 680 thousand tons in 2021 and 2020. Our ownership interest in Series A and Series B partnership units conveys us an undivided interest in certain U.S. PO Joint Venture assets with correlative PO and co-product capacity, respectively, resulting in the ownership of annual in-kind cost-based PO and co-product production. In addition, each partner has a 50% interest in a separate manufacturing joint venture (the “European PO Joint Venture”), which owns a PO/SM plant at Maasvlakte near Rotterdam, The Netherlands. In substance, each partner’s ownership interest represents an undivided interest in all of the European PO Joint Venture assets with correlative capacity reservation resulting in ownership of annual in-kind cost-based PO and SM production. We do not share marketing or product sales under the U.S. PO Joint Venture. We operate the U.S. PO Joint Venture’s and the European PO Joint Venture’s (collectively the “PO Joint Ventures”) plants and arrange and coordinate the logistics of product delivery. The partners’ share in the cost of production and logistics is based on their product off-take. During the fourth quarter of 2020, we executed a joint venture agreement with Sasol Chemicals (USA) LLC (“Sasol”) to form the Louisiana Integrated PolyEthylene JV LLC joint venture (the “Louisiana Joint Venture”). Under this arrangement, we acquired a 50% ownership interest in an ethane cracker, a low-density and linear-low density polyethylene plants, and associated infrastructure. Under the terms of the joint venture agreement, each partner provides pro-rata share of ethane feedstocks and off-takes pro-rata shares of cracker and polyethylene products. We operate the Louisiana Joint Venture assets and market the polyethylene off-take for all partners through our global sales team. We account for the PO Joint Ventures and the Louisiana Joint Venture using the equity method. We report the cost of our product off-take as inventory and the equity loss as cost of sales in our Consolidated Financial Statements. Related production cash flows are reported in the operating cash flow section of the Consolidated Statements of Cash Flows. Our equity investment in the PO Joint Ventures and the Louisiana Joint Venture represents our share of the manufacturing plants and is decreased by recognition of our share of equity loss, which is equal to the depreciation of the assets of these joint ventures. Other changes in the investment balance are principally due to our additional capital contributions to these joint ventures to fund capital expenditures. Such contributions are reported in the investing cash flow section of the Consolidated Statements of Cash Flows. Our product off-take of PO and its co-products from the PO Joint Ventures was 2.6 million tons in 2021, 2.6 million tons in 2020 and 2.4 million tons in 2019. Our product off-take of ethylene and polyethylene produced from the Louisiana Joint Venture in 2021 was 1.1 million tons. The product off-take in 2020 for the period subsequent to the formation of the joint venture was immaterial.
Redeemable noncontrolling interests [Policy Text Block]	Redeemable Non-controlling Interests Our redeemable non-controlling interests relate to shares of cumulative perpetual special stock (“redeemable non-controlling interest stock”) issued by our consolidated subsidiary, formerly known as A. Schulman, Inc. (“A. Schulman”). Holders of redeemable non-controlling interest stock are entitled to receive cumulative dividends at the rate of 6% per share on the liquidation preference of $1,000 per share. Redeemable non-controlling interest stock may be redeemed at any time at the discretion of the holders and is reported in the Consolidated Balance Sheets outside of permanent equity. The redeemable non-controlling interests were recorded at fair value at the date of acquisition and are subsequently carried at the greater of estimated redemption value at the end of each reporting period or the initial amount recorded at the date of acquisition adjusted for subsequent redemptions. Dividends on these shares are deducted from or added to the amount of Income (loss) attributable to the Company shareholders if and when declared by the Company.
Goodwill [Policy Text Block]	Goodwill Goodwill is tested for impairment annually in the fourth quarter or whenever events or changes in circumstances indicate that the fair value of a reporting unit with goodwill is below its carrying amount. We first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. Qualitative factors assessed for each of the reporting units include, but are not limited to, changes in long-term commodity prices, discount rates, competitive environments, planned capacity, cost factors such as raw material prices, and financial performance of the reporting units. If the qualitative assessment indicates that it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value, a quantitative test is required. If the carrying value of the reporting unit including goodwill exceeds its fair value, an impairment charge equal to the excess would be recognized up to a maximum amount of goodwill allocated to that reporting unit. For 2021 and 2020, management performed qualitative impairment assessments of our reporting units, which indicated that the fair value of our reporting units was greater than their carrying value including goodwill. Based on this assessment, our historical assessment for impairment and forecasted demand for our products, a quantitative goodwill impairment test was not required and no goodwill impairment was recognized.
Intangible assets [Policy Text Block]	Intangible Assets Intangible assets consist of customer relationships, trade names and trademarks, know-how, emission allowances, various contracts, in-process research and development costs and software costs. These assets are amortized using the straight-line method over their estimated useful lives or over the term of the related agreement. We evaluate definite-lived intangible assets with the associated long-lived asset group for impairment whenever impairment indicators are present.
Research and development [Policy Text Block]	Research and Development Research and development (“R&D”) costs are expensed when incurred. Subsidies for R&D are included in Other income (expense), net. Depreciation expense related to assets employed in R&D is included as a cost of R&D.
Income taxes [Policy Text Block]	Income Taxes The income tax for the period comprises current and deferred tax. Income tax is recognized in the Consolidated Statements of Income, except to the extent that it relates to items recognized in other comprehensive income or directly in equity. In these cases, the applicable tax amount is recognized in other comprehensive income or directly in equity, respectively. Deferred income taxes reflect the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts recognized for income tax purposes, as well as the net tax effects of net operating loss carryforwards. Valuation allowances are provided against deferred tax assets when it is more likely than not that some portion or all of the deferred tax asset will not be realized. We recognize uncertain income tax positions in our financial statements when we believe it is more likely than not, based on the technical merits, that the position or a portion thereof will be sustained upon examination. For a position that is more likely than not to be sustained, the benefit recognized is measured at the largest cumulative amount that is greater than 50 percent likely of being realized.
Environmental remediation costs [Policy Text Block]	Environmental Remediation Costs—Environmental remediation liabilities include liabilities related to sites we currently own, sites we no longer own, as well as sites where we have operated that belong to other parties. Liabilities for anticipated expenditures related to investigation and remediation of contaminated sites are accrued when it is probable a liability has been incurred and the amount of the liability can be reasonably estimated. Only certain post-remediation monitoring costs, the timing of which can be determined with reasonable certainty, are discounted to present value.
Asset retirement obligations [Policy Text Block]	Asset Retirement Obligations— At some sites, we are legally obligated to decommission our plants upon site exit. Asset retirement obligations are recorded at the fair value using the present value of the estimated costs to retire the asset at the time the obligation is incurred. That cost, which is capitalized as part of the related long-lived asset, is depreciated on a straight-line basis over the remaining useful life of the related asset. Accretion expense in connection with the discounted liability is also recognized over the remaining useful life of the related asset. Such depreciation and accretion expenses are included in Cost of sales.
Foreign currency translation [Policy Text Block]	Foreign Currency Translation and Remeasurement Functional and Reporting Currency —Items included in the financial information of each of LyondellBasell N.V.’s entities are measured using the currency of the primary economic environment in which the entity operates (“the functional currency”) and then translated to the U.S. dollar (“the reporting currency”) as follows: • Assets and liabilities for each balance sheet presented are translated at the closing rate at the date of that balance sheet; • Income and expenses for each income statement are translated at monthly average exchange rates; and • All resulting exchange differences are recognized as a separate component within Other comprehensive income (foreign currency translation adjustments). Transactions and Balances —Foreign currency transactions are recorded in their respective functional currency using exchange rates prevailing at the dates of the transactions. Exchange gains and losses resulting from the settlement of such transactions and from remeasurement of monetary assets and liabilities denominated in foreign currencies at the balance sheet date are recognized in earnings.
Revenue from contract with customer [Policy Text Block]	Revenue Recognition Substantially all our revenues are derived from contracts with customers. We account for contracts when both parties have approved the contract and are committed to perform, the rights of the parties and payment terms have been identified, the contract has commercial substance and collectability is probable. Revenue is recognized when obligations under the terms of a contract with our customer are satisfied. This generally occurs at the point in time when performance obligations are fulfilled and control transfers to the customer. In most instances, control transfers upon transfer of risk of loss and title to the customer, which usually occurs when we ship products to the customer from our manufacturing facility. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods. Customer incentives are generally based on volumes purchased and recognized over the period earned. Sales, value-added, and other taxes that we collect concurrent with revenue-producing activities are excluded from the transaction price as they represent amounts collected on behalf of third parties. We apply the practical expedient to recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that we otherwise would have recognized is one year or less. Shipping and handling costs are treated as a fulfillment cost and not a separate performance obligation. We have marketing arrangements to off-take and sell the production of some of our joint ventures in return for a percentage of the price realized on the sales to the end customer. In such arrangements, when we obtain control of the product, revenue and cost of sales are presented on a gross basis. Otherwise, we recognize revenue, net of amounts due to the joint venture, which represents commissions earned. Payments are typically required within a short period following the transfer of control of the product to the customer. We occasionally require customers to prepay purchases to ensure collectability. Such prepayments do not represent financing arrangements, since payment occurs within a short time frame. We apply the practical expedient which permits us to disregard the effects of a significant financing component when, at contract inception, we expect the period between the payment and fulfillment of the performance obligation will be one year or less.
Share-based compensation [Policy Text Block]	Share-Based Compensation The Company recognizes compensation expense in the financial statements for equity-classified share-based compensation awards based upon the grant date fair value over the vesting period. See Note 15 to the Consolidated Financial Statements for additional information.
Lessee, leases [Policy Text Block]	Leases Leases with a term longer than 12 months are recorded on the balance sheet as a lease asset and lease liability. If at inception of a contract, a lease is identified, we recognize a lease asset and a corresponding lease liability based on the present value of the lease payments over the lease term, discounted using our incremental borrowing rate, unless an implicit rate is readily determinable. Lease payments include fixed and variable lease components derived from usage or market-based indices, such as the consumer price index. Other variable lease payments may fluctuate for a variety of reasons including usage, output, insurance or taxes. These variable amounts are expensed as incurred and not included in the lease assets or lease liabilities. Options to extend or terminate a lease are reflected in the lease payments and lease term when it is reasonably certain that we will exercise those options. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the Consolidated Statements of Income. The majority of our leases are operating leases for which we recognize lease expense on a straight-line basis over the lease term. We apply the practical expedient to account for lease and associated non-lease components as a single lease component for all asset classes with the exception of utilities and pipeline assets within major manufacturing equipment. For these assets, non-lease components are separated from lease components and accounted for as normal operating expenses. Leases with an initial term of 12 months or less are recognized in the Consolidated Statements of Income on a straight-line basis over the lease term.
Financial instruments and hedging activities [Policy Text Block]	Financial Instruments and Hedging Activities Pursuant to our risk management policies, we selectively enter into derivative transactions to manage market risk volatility associated with changes in commodity pricing, currency exchange rates and interest rates. Certain derivatives used for this purpose are designated as net investment hedges, cash flow hedges or fair value hedges. Derivative instruments are recorded at fair value on the balance sheet. Gains and losses related to changes in the fair value of derivative instruments not designated as hedges are recorded in earnings. Cash flows from derivatives designated as hedges are reported in our Consolidated Statements of Cash Flows under the same category as the cash flows from the hedged items unless the derivative contract contains a significant financing element. Cash flows for derivatives with a significant financing element are classified as Cash flows from financing activities. Cash flows related to economic hedges are classified consistent with the cash flows of the economic hedged items. Net Investment Hedges— We enter into foreign currency derivatives and foreign currency denominated debt to reduce the volatility in shareholders’ equity resulting from changes in currency exchange rates of our foreign subsidiaries with respect to the U.S. dollar. Our foreign currency derivatives consist of cross-currency contracts and forward exchange contracts. We use the critical terms approach through the application of the spot method to assess hedge effectiveness at least quarterly. For derivatives designated as net investment hedges, gains or losses attributable to changes in spot foreign exchange rates over the designation period are reflected in foreign currency translation adjustments within Other comprehensive income (loss). Recognition in earnings is delayed until the net investment is sold or liquidated. At that time, the amount recognized is reported in the same line item as the gain or loss on the liquidation of the hedged foreign operations. For our cross-currency swaps, the associated interest receipts and payments are recorded in interest expense. For our foreign currency forward contracts, we amortize initial forward point values on a straight-line basis to interest expense over the life of the hedging instrument. We monitor on a quarterly basis for any over-hedged positions requiring re-designation and re-designation of the hedge to remove such over-hedged condition. Cash Flow Hedges— We enter into cash flow hedges to manage the variability in cash flows of a future transaction. Our cash flow hedges include cross currency swaps, forward starting interest rate swaps and commodity futures, options and swaps. For derivatives designated as cash flow hedges, the gains and losses are recorded in other comprehensive income (loss) and released to earnings in the same line item and in the same period during which the hedged item affects earnings. We use the critical terms and the quantitative long-haul methods to assess hedge effectiveness and monitor, at least quarterly, any change in effectiveness. We have cross-currency swap contracts designated as cash flow hedges to reduce our exposure to the foreign currency exchange risk associated with certain intercompany loans. Under the terms of these contracts, we make interest payments in euros and receive interest in U.S. dollars. Upon the maturities of these contracts, we will pay the principal amount of the loans in euros and receive U.S. dollars from our counterparties. We enter into forward-starting interest rate contracts to mitigate the risk of adverse changes in benchmark interest rates on future anticipated debt issuances. We also execute commodity futures, options and swaps to manage the volatility of the commodity price related to anticipated purchases of raw materials and product sales. We enter into over-the-counter commodity swaps and options with one or more counterparties whereby we pay a predetermined fixed price and receive a price based on the average monthly rate of a specified index for the specified nominated volumes. Fair Value Hedges— We use interest rate swaps as part of our current interest rate risk management strategy to achieve a desired proportion of variable versus fixed rate debt. Under these arrangements, we exchange fixed-rate for floating-rate interest payments to effectively convert our fixed-rate debt to floating-rate debt. For derivatives that have been designated as fair value hedges, the gains and losses of the derivatives and hedged items are recorded in earnings. We use the long-haul method to assess hedge effectiveness using a regression analysis approach at least quarterly. We perform the regression analysis over an observation period of three years, utilizing data that is relevant to the hedge duration. Fair Value Measurements We categorize assets and liabilities, measured at fair value, into one of three different levels depending on the observability of the inputs employed in the measurement. Level 1 inputs are quoted prices for identical instruments in active markets. Level 2 inputs are quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs or significant value-drivers are observable. Level 3 inputs are model-derived valuations in which one or more significant inputs or significant value-drivers are unobservable. Fair value measurements are classified according to the lowest level input or value-driver that is significant to the valuation. A measurement may therefore be classified within Level 3 even though there may be significant inputs that are readily observable. Changes in Fair Value Levels —Management reviews the disclosures regarding fair value measurements at least quarterly. If an instrument classified as Level 1 subsequently ceases to be actively traded, it is transferred out of Level 1. In such cases, instruments are reclassified as Level 2, unless the measurement of its fair value requires the use of significant unobservable inputs, in which case it is reclassified as Level 3. We use the following inputs and valuation techniques to estimate the fair value of our financial instruments disclosed in Note 13 to the Consolidated Financial Statements: Cross-Currency Swaps —The fair value of our cross-currency swaps is calculated using the present value of future cash flows discounted using observable inputs such as known notional value amounts, yield curves, basis curves, as applicable, and with the foreign currency leg revalued using published spot and forward exchange rates on the valuation date. Forward-Starting and Fixed-for-Floating Interest Rate Swaps —The fair value of our forward-starting and fixed-for-floating interest rate swaps is calculated using the present value of future cash flows using observable inputs such as benchmark interest rates and market yield curves. Commodity Derivatives —The fair values of our commodity derivatives are measured using closing market prices of public exchanges and from third-party broker quotes and pricing providers. The fair value of our commodity swaps classified as Level 2 is determined using a combination of observable and unobservable inputs. The observable inputs consist of future market values of various crude and heavy fuel oils, which are readily available through public data sources. The unobservable input, which is the estimated discount or premium used in the market pricing, is calculated using an internally-developed, multi-linear regression model based on the observable prices of the known components and their relationships to historical prices. A significant change in this unobservable input would not have a material impact on the fair value measurement of our Level 2 commodity swaps. Forward Exchange Contracts —The fair value of our forward exchange contracts is based on forward market rates. Available-for-Sale Debt Securities— The fair value of our available-for-sale debt securities is calculated using observable market data for similar securities and broker quotes from recognized purveyors of market data. Equity Securities— The fair value of our investment in equity securities is based on the net asset value provided by the fund administrator. Short-Term Debt —The fair value of short-term borrowings related to precious metal financing arrangements accounted for as embedded derivatives are determined based on the future price of the associated precious metal. Long-Term Debt —The fair value of our senior and guaranteed notes is calculated using pricing data obtained from well-established and recognized vendors of market data for debt valuations. The fair value of our term loan was determined based on a discounted cash flow model using observable inputs such as benchmark interest rates and public information regarding our credit risk. We use the following inputs and valuation techniques to estimate the fair value of our pension assets disclosed in Note 14 to the Consolidated Financial Statements: Common and Preferred Stock— Valued at the closing price reported on the market on which the individual securities are traded. Fixed Income Securities— Certain securities that are not traded on an exchange are valued at the closing price reported by pricing services. Other securities are valued based on yields currently available on comparable securities of issuers with similar credit ratings. Commingled Funds— Valued based upon the unit values of such collective trust funds held at year end by the pension plans. Unit values are based on the fair value of the underlying assets of the fund derived from inputs principally from, or corroborated by, observable market data by correlation or other means. Real Estate— Valued on the basis of a discounted cash flow approach, which includes the future rental receipts, expenses, and residual values as the highest and best use of the real estate from a market participant view as rental property. Hedge Funds— Valued based upon the unit values of such alternative investments held at year end by the pension plans. Unit values are based on the fair value of the underlying assets of the fund. Private Equity— Valued based upon the unit values of such alternative investments held at year end by the pension plans. Unit values are based on the fair value of the underlying assets of the fund. Certain securities held in the fund are valued at the closing price reported on an exchange or other established quotation service for over-the-counter securities. Other assets held in the fund are valued based on the most recent financial statements prepared by the fund manager. Convertible Securities— Valued at the quoted prices for similar assets or liabilities in active markets. U.S. Government Securities— Certain securities are valued at the closing price reported on the active market on which the individual securities are traded. Other securities are valued based on yields currently available on comparable securities of issuers with similar credit ratings. Cash and Cash Equivalents— Valued at the quoted prices for identical assets or liabilities in active markets. Non-U.S. Insurance Arrangements —Valued based upon the estimated cash surrender value of the underlying insurance contract, which is derived from an actuarial determination of the discounted benefits cash flows.
Fair value measurement [Policy Text Block]	Fair Value Measurements We categorize assets and liabilities, measured at fair value, into one of three different levels depending on the observability of the inputs employed in the measurement. Level 1 inputs are quoted prices for identical instruments in active markets. Level 2 inputs are quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs or significant value-drivers are observable. Level 3 inputs are model-derived valuations in which one or more significant inputs or significant value-drivers are unobservable. Fair value measurements are classified according to the lowest level input or value-driver that is significant to the valuation. A measurement may therefore be classified within Level 3 even though there may be significant inputs that are readily observable.
Pension plans [Policy Text Block]	Pension Plans— We have funded and unfunded defined benefit plans and defined contribution plans. For the defined benefit plans, a projected benefit obligation is calculated annually by independent actuaries using the projected unit credit method. Pension costs primarily represent the increase in the actuarial present value of the obligation for pension benefits based on employee service during the year and the interest on this obligation in respect of employee service in previous years, net of expected return on plan assets. Actuarial gains and losses arising from experience adjustments and changes in actuarial assumptions are charged or credited to equity and are reflected in Accumulated other comprehensive income in the period in which they arise.
Other post-employment obligations [Policy Text Block]	Other Post-Employment Obligations— Certain employees are entitled to post-retirement medical benefits upon retirement. The entitlement to these benefits is usually conditional on the employee remaining in service up to retirement age and the completion of a minimum service period. The expected costs of these benefits are accrued over the period of employment applying the same accounting methodology used for defined benefit plans.
Termination benefits [Policy Text Block]	Termination Benefits— Contractual termination benefits are payable when employment is terminated due to an event specified in the provisions of a social/labor plan or statutory law. A liability is recognized for one-time termination benefits when we are committed to (i) make payments and the number of affected employees and the benefits to be received are known to both parties, and (ii) terminating the employment of current employees according to a detailed formal plan without possibility of withdrawal and can reasonably estimate such amount. Benefits falling due more than 12 months after the balance sheet date are discounted to present value.
Use of estimates [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Events surrounding the COVID-19 pandemic continue to evolve and negatively impact global markets and demand for our products. We continue to assess the potential financial statement impacts of COVID-19 and commodity price volatility throughout the duration of the pandemic. The extent of the impact of the pandemic on our operational and financial performance will depend on future developments which are uncertain and cannot be predicted. An extended period of economic disruption could have a material adverse impact on our business, results of operations, access to sources of liquidity and financial condition.
New accounting pronouncements, policy [Policy Text Block]	Recently Adopted Guidance Equity Method and Joint Ventures —In January 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-01, Investments—Equity Securities (Topic 321), Investments— Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815. The guidance clarifies that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321. The standard also includes scope considerations for entities that hold certain non-derivative forward contracts and purchased options to acquire equity securities that, upon settlement of the forward contract or exercise of the purchase option, would be accounted for under the equity method of accounting. This guidance is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. The prospective adoption of this guidance from January 1, 2021 did not have a material impact on our Consolidated Financial Statements. Convertible Instruments— In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging— Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. The guidance simplifies the accounting for convertible instruments and the application of the derivatives scope exception for contracts in an entity’s own equity. The standard also amends the accounting for convertible instruments in the diluted earnings per share calculation and requires enhanced disclosures of convertible instruments and contracts in an entity’s own equity. The guidance is effective for fiscal years beginning after December 15, 2021 and may be applied on a modified or fully retrospective basis. The early adoption of this guidance on a modified retrospective basis from January 1, 2021 did not have a material impact on our Consolidated Financial Statements. Debt —In October 2021, the FASB issued ASU 2020-09, Debt (Topic 470): Amendments to SEC Paragraphs Pursuant to SEC Release No. 33-10762. This guidance amends and supersedes SEC paragraphs in the Accounting Standards Codification to reflect the issuance of SEC Release No. 33-10762 related to financial disclosure requirements for subsidiary issuers and guarantors of registered debt securities and affiliates whose securities are pledged as collateral for registered securities. The guidance is effective for annual and interim periods ending after January 4, 2021. The adoption of this guidance from January 1, 2021 did not have a material impact on our Consolidated Financial Statements. Accounting Guidance Issued But Not Adopted as of December 31, 2021 Government Assistance —In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance. The guidance requires disclosures about assistance received from the government that have been accounted for by analogizing to a grant or contribution accounting model including the nature and form of assistance, the accounting policies used to account for the assistance and its impact on the entity’s financial statements. The guidance is effective for annual periods beginning after December 15, 2021, with early application permitted. The adoption of this guidance will not have a material impact on our Consolidated Financial Statements.

Rate of compensation increase (in hundredths)	4.63%	4.83%	4.83%
Description of basis used to determine overall expected long-term rate of return, on asset assumptions	We measure service and interest costs by applying the specific spot rates along that same yield curve to the projected cash flows of the plans. This approach provides a more precise measurement of service and interest costs. The weighted average expected long-term rate of return on assets in our U.S. plans of 7.25% is based on the average level of earnings that our independent pension investment adviser had advised could be expected to be earned over a fifteen to twenty year time period consistent with the target asset allocation of the plans, historical capital market performance, historical plan performance (since the 1997 inception of the U.S. Master Trust) and a forecast of expected future asset returns. The weighted average expected long-term rate of return on assets in our non-U.S. plans of 1.44% is based on expectations and asset allocations that vary by region. We review these long-term assumptions on a periodic basis.

Share-based compensation disclosures [Line Items]
Description of award	A target number of PSUs is granted to participants at the beginning of a three-year performance period. Final payout of awards, which can range from 0% to 200% of target shares granted, is determined and paid after the performance period. These awards are settled in shares of common stock, and each unit is equivalent to one share of our common stock.The payout for PSUs granted after February 2021 will be equally based on Total Shareholder Return (“TSR”) relative to our peers and a performance metric. The fair value of the portion of the award that vests based on TSR is estimated using a Monte-Carlo simulation. For the other portion of the award, the fair value is determined based on our stock price and the number of target shares expected to vest at the end of each reporting period. Prior to 2021, all our PSUs vesting was based on TSR relative to our peers, and the fair value was estimated using a Monte-Carlo simulation.Outstanding PSUs accrue dividend equivalent units, which will be converted to shares upon payment at the end of the performance period and are classified as Accrued liabilities and Other liabilities on the Consolidated Balance Sheets. Dividend equivalents for PSUs are recorded in Retained earnings.
