Basis of Presentation [Text Block]	1. Basis of Presentation LyondellBasell Industries N.V., together with its consolidated subsidiaries (collectively “LyondellBasell N.V.”), is a worldwide manufacturer of chemicals and polymers, a refiner of crude oil, a significant producer of gasoline blending components and a developer and licensor of technologies for production of polymers. Unless otherwise indicated, the “Company , ” “we,” “us,” “our” or similar words are used to refer to LyondellBasell N.V. The accompanying Consolidated Financial Statements are unaudited and have been prepared from the books and records of LyondellBasell N.V. in accordance with the instructions to Form 10-Q and Rule 10-1 of Regulation S-X for interim financial information. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States (“U.S. GAAP”) for complete financial statements. In our opinion, all adjustments, consisting only of normal recurring adjustments, considered necessary for a fair presentation have been included. The results for interim periods are not necessarily indicative of results for the entire year. These Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and notes thereto for the year ended December 31, 2015 .

Accounting and Reporting Changes [Abstract]
Accounting and Reporting Changes [Text Block]	2. Accounting and Reporting Changes Recently Adopted Guidance Compensation —In June 2014, the FASB issued ASU 2014-12 , Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period . Under this new guidance, entities are required to treat performance targets that affect vesting and could be achieved after the requisite service period as a performance condition. The amendments in thi s ASU were effective for annual and interim periods beginning after December 15, 201 5. Early adoption is permitted. The adoption of this amendment did not have a material impact on our Consolidated Financial Statements . Consolidation —In February 2015, the FASB issued ASU 2015-02, Co nsolidation (Topic 810) : Amendments to the Consolidation Analysis , which amends and changes the consolidation analysis currently required under U.S. GAAP. This ASU modif ies the process used to evaluate whether limited partnership s and similar entities are variable interest entities ( “ VIEs ” ) or voting interest entities ; affects the analysis performed by reporting entities regarding VIEs, particularly those with fee arrangements and related party relationships ; and provides a scope exception for certain investment funds. The amendments in this update were effective for annual and interim periods beginning after December 15, 2015. Early adoption is permitted. The adoption of this amendment did not have a material impact on our Consoli dated Financial Statements . Accounting Guidance Issued But Not Adopted as of September 30, 2016 Revenue Recognition —In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) , which supersedes the current revenue recognition re quirements in Accounting Standard Codification (“ ASC ”) 606, Revenue Recognition. Under this guidance, entities should recognize revenues to depict the transfer of promised goods or services to customers in an amount that reflects the consideration the enti ty expects to receive in exchange for those goods or services. This ASU also requires enhanced disclosures. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date , which deferred the o riginal effective date for one year to annual and interim periods beginning after December 15, 2017. Retrospective and modified retrospective application is allowed. Amendments to Revenue Recognition —In 2016 the FASB issued several amendments to Topic 606, Revenue from Contracts with Customers. ASU 2016-08, Principal versus Agent Considerations, contains amendments that clarify the implementation guidance on principal versus agent considerations. ASU 2016-10, Identifying Performance Obligations an d Licensing clarifies the guidance in the new revenue standard on identifying performance obligations and accounting for licenses of intellectual property . The FASB also issued ASU 2016-12, Narrow-Scope Improvements and Practical Expedients , whi ch further clarifies the new revenue guidance primarily in the areas of collectability, noncash consideration, presentation of sales tax, and transition. All amendments are effective with the same date as ASU 2014-09. We are currently assessing the impact of Topic 606 together with its amendments on our Consolidated Financial Statements. Going Concern— In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity ’s Ability to Continue as a Going Concern. Under this new guidance, management is required to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued (or a vailable to be issued when applicable). Additionally, the entity must provide certain disclosures if conditions or events raise substantial doubt about its ability to continue as a going concern. The amendments in this update are effective for annual perio ds ending after December 15, 2016 and interim periods thereafter. Early adoption is permitted. The application of this amendment is not expected to have a material impact on our Consolidated Financial Statements. Inventories —In July 2015, the FASB issued A SU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. Under this new guidance, entities that measure inventory using any method other than last-in, first-out or the retail inventory method will be required to measure inventory at the lower of cost and net realizable value. The amendments in this ASU, which should be applied prospectively, are effective for annual and interim periods beginning after December 15, 2016. Early adoption is permitted. The application of this amendment is no t expected to have a material impact on our Consolidated Financial Statements. Financial Instruments —In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financi al Liabilities . The new guidance in this ASU includes a requirement for equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. Prospective application of this ASU is required for public entities for annual and interim periods beginning on or after December 15, 2017. We are currently assessing the impact of this new guidance on our Consolidated Financial Statements. Lease s —In February 2016, the FASB issued ASU 2016-0 2 , Leases ( T opic 842 ) , creating Topic 842 which supersedes the existing guidance for lease accounting in ASC 840 , Leases . Under the new guidance, for leases with a term longer than 12 months a lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term . Topic 842 r etains a classification distinction between finance leases and operating leases, with the classification affecting the pattern of expense recognition in the income statement . This ASU also requires enhanced disclosures. A m odified retrospective transition approach is required for annual and interim periods beginning on or after December 15, 201 8 . Early adoption is permitted. We are currently assessing the impact of this new guidance on our Consolidated Financial Statements. Derivatives and Hedging — In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments . The ASU clarifies that in assessing whether an embedded contingent put or call option is clearly and closely related to the debt ho st, an entity is required to apply only the four-step decision sequence as described in the amended guidance. The ASU is effective for public entities for annual and interim periods beginning after December 15, 2016. Early adoption is permitted. We are cur rently assessing the impact of the amended guidance on our Consolidated Financial Statements. Investments — In March 2016, the FASB issued ASU 2016-07, Investments – Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting . This ASU simplifies the recognition and reporting requirements for investments that become qualified for the equity method of accounting as a result of an increase in the level of ownership interest or degree of influence. The amendments in this ASU are effective for all entities for annual and interim periods beginning after December 15, 2016. Prospective application is required to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Early adoption is permitted. The application of this amendment is not expected to have a material impact on our Consolidated Financial Statements. Compensation —In March 2016, the FASB issued ASU 2016-09, Compensation–Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting . This ASU simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and class ification on the statement of cash flows. The amendments in this ASU are effective for public entities for annual and interim periods beginning after December 15, 2016. Various transition methods are prescribed depending on the aspect of accounting impacte d by the amended guidance. Early adoption is permitted. We are currently assessing the impact of the amendments in this guidance on our Consolidated Financial Statements. Financial Instruments —In June 2016, the FASB issued ASU 2016-13, Financial Instrument s – Credit Losses (Topic 326) : Measurement of Credit Losses on Financial Instruments . This amendment requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected, resulting in the use of a current ex pected credit loss (“CECL”) model when measuring an impairment of financial instruments. Credit losses related to available-for-sale securities should be recorded in the consolidated income statement through an allowance for credit losses. Estimated credit losses utilizing the CECL model are based on reasonable use of historical experience, current conditions and forecasts that affect the collectability of reported financial assets. This ASU also modifies the impairment model for available-for-sale debt sec urities by eliminating the concept of “other than temporary” as well as providing a simplified accounting model for purchased financial assets with credit deterioration since their origination. The guidance will be effective for public entities for annual and interim periods beginning after December 15, 2019. Early adoption is permitted. We are currently assessing the impact of the amendments in this guidance on our Consolidated Financial Statements. Statement of Cash Flows —In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . The updated accounting requirement is intended to reduce diversity in practice in the classification of certain tr ansactions in the statement of cash flows. Such transactions include but are not limited to debt prepayment or debt extinguishment costs, settlement of zero coupon debt instruments, contingent consideration payments made after a business combination and distributions received from equity method of investments. The amendments in this ASU are effective for public entities for annual and interim periods beginning after December 15, 2018. A retrospective transition approach is required and early adoption is p ermitted. We are currently assessing the impact of this new guidance on our Consolidated Financial Statements.

These unsecured notes, which are fully and unconditionally guaranteed by LyondellBasell Industries N.V ., rank equally in right of payment to all of LYB Finance II’s existing and future u nsecured indebtedness and to all of LyondellBasell N.V.’s existing and future unsubordinated indebtedness. There are no significant restrictions that would impede LyondellBasell N.V. , as guarantor, from obtaining funds by dividend or loan from its subsidiaries. The indenture governing the se notes contains 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 ow n 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. The notes may be redeemed before the date tha t is three months prior to the scheduled maturity date at a redemption price equal to the greater of 100% of the principal amount of the notes redeemed and the sum of the present values of the remaining scheduled payments of principal and interest (discoun ted at the applicable Comparable Government Bond Rate plus 35 basis points) on the notes to be redeemed. The notes may also be redeemed on or after the date that is three months 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 accrued and unpaid interest. The notes are also redeemable upon certain tax events. Short-Term Debt Senior Revolving Credit Facility ―In June 2016 , the term of our revolving credit facility was extended for one year to June 2021 pursuant to a consent agreement. We also amended the revolving credit facility in June 2016 to increase its size to $2,500 million. All other material terms of the revol ving credit facility remained unchanged. The revolving credit facility may be used for dollar and euro denominated borrowings, has a $ 5 00 million sublimit for dollar and euro denominated letters of credit , a $1,000 million uncommitted accordion feature, a nd supports our commercial paper program . The aggregate balance of outstanding borrowings and letters of credit under this facility may not exceed $2,500 million at any given time. Borrowings under the facility bear interest at a Base Rate or LIBOR, plus a n applicable margin. Additional fees are incurred for the average daily unused commitments. The facility contains customary covenants and warranties, including specified restrictions on indebtedness and liens. In addition, we are required to maintain a l everage ratio at the end of every quarter of 3.50 to 1.00 or less for the period covering the most recent four quarters. We are in compliance with these covenants as of September 30, 2016 . At September 30, 2016 , we had $500 million of outstanding commercial paper, no outstanding letters of credit and no outstanding borrowings under this facility. Commercial Paper Program ― In June 2016, in connection with the increase of our revolving credit facility, we increased the size of our commercial paper pro gram to $2,500 million. We may issue up to $ 2,500 million of privately placed, unsecured, short-term promissory notes (“commercial paper”) under this program, which is backed by our $2,500 million Senior Revolving Credit Facility. Proceeds from the issuanc e of commercial paper may be used for general corporate purposes, including dividends and share repurchases. U.S. Receivables Securitization Facility ― Our $900 million U.S. accounts receivable securitization facility , which expires in 2018, has a purchase limit of $900 million in addition to a $ 300 million uncommitted accordion feature . 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. In the event of liquidation, the bankruptcy-remote subsidiary’s assets will be used to satisfy the claims of its creditors prior to any assets or value in the bankruptcy-remote subs idiary becoming available to us. We are responsible for servicing the receivables. This facility also provides for the issuance of letters of credit up to $ 200 million. The term of the securitization facility may be extended in accordance with the terms of the agreement. At September 30, 2016 , t here were no borrowings or letters of credit outstanding under the f acility. European Receivables Securitization Facility ―Our €450 million European receivables securitization facility expired in April 2016. Other ― A t September 30, 2016 and December 31, 2015 , our weighted average interest rate on outstanding short-term debt was 0.7 %. Debt Discount and Issuance Costs In each of the nine months ended September 30, 2016 and 2015 , amortization of debt discounts and debt issuance costs resulted in amortization expense of $ 12 million, which is included in Interest expense in the Consolidated Statements of Income.

Financial Instruments [Abstract]
Financial Instruments [Text Block]	7. Financial Instruments Cash Concentration ― Our cash equivalents are placed in high-quality commercial paper, money market funds and time deposits with major international banks and financial institutio ns. Market Risks —We are exposed to market risks, such as changes in commodity pricing, currency exchange rates and interest rates. To manage the volatility related to these exposures, we selectively enter into derivative transactions pursuant to our risk management policies. 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. For derivatives that have been d esignated as fair value hedges, the gains and losses of the derivatives and hedged instruments are recorded in earnings. For derivatives designated as cash flow and net investment hedges, the effective portion of the gains and losses is recorded in O ther c omprehensive income (loss). The ineffective portion of cash flow and net investment hedges is recorded in earnings. Marketable Securities ―We invest cash in investment-grade securities for periods generally not exceeding two years. Investments in securitie s with original maturities of three months or less are classified as Cash and cash equivalents. At September 30, 2016 and December 31, 2015 , we had marketable securities classified as Cash and cash equivalents of $ 249 million and $ 575 million, respe ctively. We also have investments in marketable securities classified as available-for-sale and held-to-maturity . These securities are included in Short-term investments on the Consolidated Balance Sheets . Investments classified as available-for-sa le are carried at estimated fair value with unrealized gains and losses recorded as a component of Accumulated other comprehensive income (“AOCI”). Investment s classified as held-to-maturity are carried at amortized cost. We periodically review our available-for-sale and held-to-maturity securities for other-than-temporary declines in fair value below the cost basis, and when events or changes in circumstances indicate the carrying value of an asset may not be recoverable, the investment is written down to fair value, establishing a new cost basis. Repurchase Agreements ― W e invest in tri-party repurchase agreements . Under these agreements, we make cash purchases of securities according to a pre-agreed profile from our counterparties . The counterparties have an obligation to repurchase, and we have an obligation to sell, the same or substantially the same securities at a pre-defined date for a price equal to the purchase price plus interest . These securities, which pursuant to our internal polic ies, are held by a third-party cu stodian and must g enerally have a minimum collateral value of 102%, secure the counterparty’s obligation to repurchase the securities . Depending upon maturity, t hese tri-party repurchase agreements are treated as short-term loans receivable and are reflected in Prepaid expe nses and other current assets or as long-term loans receivable reflected in Other investments and long-term receivables on our Consolidated Balance Sheets . The balance of our investment at September 30, 2016 and December 31, 2015 was $ 296 million and $ 387 million, respectively Commodity Prices ―We are exposed to commodity price volatility related to anticipated purchases of natural gas liquids, crude oil and other raw materials and sales of our products. We selectively use over-the counter commodity swaps, options and exchange traded futures contracts with various terms to manage the volatility related to these risks. In addition, we are exposed to volatility on the prices of precious metals to the extent that we have obligations, classified as embedded derivatives, tied to the price of precious metals associated with secured borrowings. All aforementioned contracts are generally limited to durations of one year or less. At September 30, 2016 , commodity futures contracts in the notional amount of $119 millio n , maturing from October 2016 to January 2017 , were outstanding. Foreign Currency Rates ―We have significant worldwide operations. The functional currencies of our consolidated subsidiaries through which we operate are primarily the U.S. dollar and the euro. We enter into transactions denominated in currencies other than our designated functional cur rencies. As a result, we are exposed to foreign currency risk on receivables and payables. We maintain risk management control policies intended to monitor foreign currency risk attributable to our outstanding foreign currency balances. These control polic ies involve the centralization of foreign currency exposure management, the offsetting of exposures and the estimating of expected impacts of changes in foreign currency rates on our earnings. We enter into foreign currency forward contracts to reduce the effects of our net currency exchange exposures. At September 30, 2016 , foreign currency forward contracts in the notional amount of $ 28 1 million, maturing from October 201 6 through December 201 6 , were outstanding. For forward contracts that economically hedge recognized monetary assets and liabilities in foreign currencies and that are not designated as net investment hedges , no hedge accounting is applied. Changes in the fair value of foreign currency forward contracts, which are reported i n the Consolidated Statements of Income, are offset in part by the currency translation results recognized on the assets and liabilities. Foreign Currency Gain (Loss) ―Other income, net, in the Consolidated Statements of Income reflected a gain of $ 1 million and a loss of $ 5 million for the three and nine months ended September 30, 2016 , and gains of $ 3 million and $ 7 million for the three and nine months ended September 30, 2015 , respectively. Basis Swaps— In 2015, we entered into € 850 million of cross-currency floating-to-floating interest rate swaps (“basis swaps”) to reduce the volatility in stockholders ’ equity resulting from changes in currency exchange rates of our foreign subsidiaries with respect to the U.S. dollar . Under the terms of these contracts, which have been designated as net investment hedges, we will make interest payments in euros at 3 Mon th EURIBOR plus basis and will receive interest in U.S. dollars at 3 Month LIBOR. Upon the maturities of these contracts, we will pay the principal amount in euros and receive U.S. dollars from our counterparties. We use the long-haul method to assess hedg e effectiveness using a regression analysis approach under the hypothetical derivative method. We perform the regression analysis of our basis swap contracts at least on a quarterly basis over an observation period of three years, utilizing data that is re levant to the hedge duration. We use the forward method to measure ineffectiveness. The effective portion of the unrealized gains and losses on these basis swap contracts is reported within Foreign currency translation adjustments in Accumulated other comp rehensive loss and reclassified to earnings only when realized upon the sale or upon complete or substantially complete liquidation of the investment in the foreign entity. Cash flow s from basis swaps are reported in Cash flows from investing activities in the Consolidated Statement of Cash Flows. In September 2016, € 450 million of our basis swaps expired . Upon settlement of these basis swap contracts , which had a notional value of $ 500 million, we paid € 450 million ($ 506 million at the expiry spot rate) to our counterparties and received $ 500 million from our counterparties . The $ 6 million loss is reflected in foreign currency translation adjustments in Accumulated other comprehensive loss. Cash flows from the settlement of these basis swap contracts are reported in Cash flows from investing activities in the Consolidated Statement s of Cash Flows. There was no ineffectiveness recorded during the three and nine months ended September 30, 2016 and 2015 related to these basis swaps. The following table summarizes the notional and fair value of our basis swaps outstanding: September 30, 2016 December 31, 2015 Millions of dollars Notional Value Fair Value Liabilities Notional Value Fair Value Assets Basis swaps expiring in 2016 $ - $ - $ 500 $ 10 Basis swaps expiring in 2017 305 (2) 305 6 Basis swaps expiring in 2018 139 (1) 139 2 Forward Exchange Contracts— In 2015, we entered into forward exchange contracts with an aggregate notional value of € 750 million ($ 795 million) to mitigate the risk associated with the fluctuations in the Euro to U.S. d ollar exchange rate related to our investments in foreign subsidiaries. These forward exchange contracts, which were designated as net investment hedges, expired on March 31, 2016. Upon settlement of these contracts, we paid € 750 million ($ 850 million at the expiry spot rate) to our counte rparties and received $ 795 million from our counterparties. The $ 55 million difference, which includes a $ 3 0 million loss in the first quarter of 2016, is reflected within foreign currency translation adjustments in Accumulated other comprehensive loss. Ca sh flows from these forward exchange contracts are reported in Cash flows from investing activities in the Consolidated Statement of Cash Flows. There was no ineffectiveness recorded for this hedging relationship during the three months ended March 31, 2016 . Guaranteed Euro Notes Due 2022 —In March 2016, we issued euro d en ominated notes payable due 2022 (“Euro notes”) with notional amounts totaling € 750 million . To mitigate the risk to our investments in foreign subsidiaries associated with fluctuations in the euro to U.S. d ollar exchange rate, we designated the se Euro notes as a net investment hedge . We use the critical terms match to assess both prospective and retrospective hedge effectiveness by comparing the spot rate change in the Euro notes and the spot rate change in the designated net investment . We use the hypothetical derivative method to measure hedge ineffectiveness. The effective portion of the gain or loss is recorded within foreig n currency translation adjustments in Accumulated other comprehensive loss and will be reclassified to earnings only when realized upon the sale of or the complete or substantially complete liquidation of the investment in the foreign entity. In periods wh ere the hedging relationship is deemed ineffective, changes in remeasurement of the Euro notes due to changes in the spot exchange rate will be recorded directly to Other income, net in the Consolidated Statements of Income. Cash flows related to our Euro notes are reported in Cash flows from financing activities and related interest payments are reported in Cash flows from operating activities in the Consolidated Statement of Cash Flows. There was no ineffectiveness recorded for this hedging relationship in the three and nine months ended September 30, 2016 . Cross - Currency Swaps — We have cross-currency swap contracts that reduce our exposure to the foreign currency exchange risk associated with certain intercompany loans. Under the terms of these contracts, which have been designated as cash flow hedges, 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 use the long-haul method to assess he dge effectiveness using a regression analysis approach under the hypothetical derivative method. We perform the regression analysis over an observation period of three years, utilizing data that is relevant to the hedge duration. We use the dollar offset m ethod under the hypothetical derivative method to measure ineffectiveness. The effective portion of the unrealized gains and losses on these cross-currency swap contracts is reported in Accumulated other comprehensive loss and reclassified to earnings ove r the period that the hedged intercompany loans affect earnings based on changes in spot rates. The ineffective portion of the unrealized gains and losses is recorded directly to Other income, net in the Consolidated Statements of Income. In addition, the swaps are marked-to-market each reporting period with the euro notional values measured based on the current foreign exchange spot rate. There was no ineffectiveness recorded during the three and nine months ended September 30, 2016 and the year ended D ecember 31, 2015 . The following table summarizes our cross-currency swaps outstanding: September 30, 2016 December 31, 2015 Millions of dollars, except Expiration Average Notional Fair Notional Fair expiration date and rates Date Interest Rate Value Value Value Value Pay Euro 2021 4.55% $ 1,000 $ 117 $ 1,000 $ 141 Receive U.S. dollars 6.00% Pay Euro 2024 4.37% 1,000 113 1,000 145 Receive U.S. dollars 5.75% Pay Euro 2027 3.69% 300 (5) 300 14 Receive U.S. dollars 5.49% Forward-Starting Interest Rate Swaps— In March 2015, we entered into forward-starting interest rate swaps to mitigate the risk of adverse changes in the benchmark interest rates on the anticipated refinancing of our senior notes due 2019 . These interest rate swaps will be terminated upon debt issuance. The total notional amount of these forward-starting interest rate swaps was $ 1,000 million at September 30, 2016 . The ineffectiveness recorded for this hedging relationship were losses of less than $1 million an d $1 million during the three and nine months ended September 30, 2016 , respectively , and losses of less than $1 million during each of the three and nine months ended September 30, 2015. In January 2015, we entered into forward-starting interest rate s waps with a total notional value of $ 750 million to mitigate the risk of adverse changes in the benchmark interest rates on the Company’s planned issuance of fixed-rate debt in 2015. These forward-starting interest rate swaps were ter minated upon issuance of the $ 1,000 million senior notes due 2055 in March 2015. The ineffectiveness recorded for this hedging relationship was less than $1 million during the nine months ended September 30, 2015 . W e elected to designate these forward-starting interest rate swaps as cash flow hedges. The effective portion of the gain or loss is recorded in Accumulated other comprehensive loss. In periods where the hedging relationship is deemed ineffective, the ineffective portion of the changes in the fair value will be recorded as Interest expense in the Consolidated Statements of Income. We use a regression analysis approach under the hypothetical derivative method to assess both prospective and retrospective hedge effectiveness. We use the dollar-offset method under the hypothetic al derivative method to measure hedge ineffectiveness. There was no settlement of our forward-starting swap agreements during the three and nine months ended September 30, 2016 . W e recognized a gain of $ 15 million in A ccumulated other comprehensive loss related to the settlement of our forward-starting interest rate swap agreements in 2015. The related deferred gains and losses recognized in A ccumula ted other comprehensive loss are amortized to interest expense over the original term of the related swaps using the effective interest method. As of September 30, 2016 , less than $1 million (on a pretax basis) is scheduled to be reclassified as an increase to interest expense over the next twelve months . Fixed-for-Floating Interest Rate Swap s — W e have U.S. dollar fixed-for-floating interest rate swaps with third party financial institution s to mitigate changes in the fair value of our $ 2,000 million 5 % senior notes due 2019 associated with the risk of variability in the 3 Month U SD LIBOR rate (the benchmark interest rate) . T hese interest rate swaps are used as part of our current interest rate risk management strategy to achieve a desired proportion of variable versus fixed rate debt . Under these arrang ements, we exchange fixed-rate for floating-rate interest payments to effectively convert our fixed - rate debt to floating rate - debt . The fixed and variable cash payments related to the interest rate swaps are net settled semi-annually and classified as Oth er, net, in the Cash flows from operating activities section of the Consolidated Statements of Cash Flows . W e have elected to designate these fixed-for-floating interest rate swaps as fair value hedges . We use the long-haul method to assess hedge effective ness using a regression analysis approach. We perform the regression analysis over an observation period of three years, utilizing data that is relevant to the hedge duration. We use the dollar offset method to measure ineffectiveness. C hanges in the fair value of the derivatives and changes in the value of the hedged items based on changes in the benchmark interest rate are recorded as Interest expense in our Consolidated Statements of Income . We evaluate the effectiveness of the hedging relationship perio dically and calculate the change s in the fair value of the derivatives and the underlying hedged item s separately . W e recognized a net loss of $ 8 million and a net gain of $ 26 million for the three and nine months ended September 30, 2016 , respectively, and net gains of $ 10 million and $ 32 million for the three and nine months ended September 30, 2015 , respectively, related to the ineffectiveness of our hedging relationships . At September 30, 2016 , we had outstanding interest rate swap agreements with notional amounts of $ 2,000 million, maturing o n April 15, 2019 . Investments in marketable securities — Our investments in marketable securities are reflected in the following table.

The amounts presented in this table are intended to facilitate reconciliation to the Consolidated Balance Sheets. There were no transfers between Level 1 and Level 2 during the nine months ended September 30, 2016 and the year ended December 31, 2015 . The following table presents the carrying value and estimated fair value of our financial instruments that are not measured at fair value on a recurring basis as of September 30, 2016 and December 31, 2015 . Short-term loans receivable , which represent our repurchase agreements , and short-term and long-term debt, are recorded at amortized cost in the Consolidated Balance Sheets. The carrying and fair values of shor t-term and long-term debt exclude capital leases.

Current assets include Cash and cash equivalents, Restricted cash, held-to-maturity time deposits and Accounts receivable. We use the following inputs and valuation techniques to estimate the fair valu e of our financial instruments: Basis Swaps― The fair value of our basis swap contracts is calculated using the present value of future cash flows discounted using observable inputs such as known notional value amounts, yield curves, spot and forward exchange rates . 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 with the foreign currency leg revalued using publis hed spot and future exchange rates on the valuation date. Forward-Starting Interest Rate Swaps —The fair value of our forward-starting interest rate swaps is calculated using the present value of future cash flows method and based on observable inputs such as benchmark interest rates. Fixed-for-Floating Interest Rate Swaps —The fair value of our fixed-for-floating interest rate swaps is calculated using the present value of future cash flows method and based on observable inputs such as interest rates and ma rket yield curves. Commodity and Embedded Derivatives —The fair value s of our commodity derivatives classified as Level 1 and embedded derivatives are measured using closing market price s at the end of the reporting period obtained from the New York Mercan tile Exchange 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 valu es 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 regre ssion 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. Foreign Currency Derivatives and Forward Exchange Contracts ― The fair value of our foreign currency derivatives is based on forward market rates. Available-for-Sale Securities— Fair value is calculated using observable market data for similar securities and broker quotes from recognized purveyors of market data or the net asset value for limited partnership investments provided by the fund administrator. Performance Share Awards— Fair value is determined using the quoted market price of our stock. Short-Te rm and Long-Term Loans Receivable — Valuations are based on discounted cash flows, which consider prevailing market rates for the respective instrument maturity in addition to corroborative support from the minimum underlying collateral requirements. Short -T erm Debt —Fair value s of short-term borrowings related to precious metal financing arrangements are determined based on the current market price of the associated precious metal. Long-Term Debt —Fair value is calculated using pricing data obtained from well -established and recognized vendors of market data for debt valuations.

Income Taxes [Abstract]
Income Taxes [Text Block]	10. Income Taxes Our effective income tax rate for the third quarter of 2016 was 25.4% compared with 29.1% for the third quarter of 2015 . For the first nine months of 2016 , the effective income tax rate was 26.4% compared with 28.5% for the first nine months of 2015 . Our effective tax rate fluctuates based on, among other factors, changes in pretax income in countries with varying statutory tax rates, the U.S. domestic production activity ded uction, changes in valuation allowances and changes in unrecognized tax benefits associated with uncertain tax positions. Compared with the third quarter of 2015 , the lower effective tax rate for the third quarter of 2016 was primarily attributab le to an in crease in exempt income, changes in pretax income in countries with varying statutory tax rates, and changes in return to accrual adjustments, partially offset by a decrease in the U.S. domestic production activity deduction . Compared with the f irst nine months of 2015, the lower effective tax rate for the first nine months of 2016 was primarily attributable to an increase in exempt income, the impact of a change in tax law on our deferred tax liabilities , and changes in pretax income in countries with varying statutory tax rates, partially offset by adjustments to our deferred tax liabilities and an increase in foreign exchange gains . A portion of the Company’s interest income from internal financing is either untaxed or taxed at rates s ubstantially lower than the U.S. statutory rate. In September , 2016 , the UK enacted provisions (the so called “anti-hybrid provisions”), effective for years beginning January 1, 2017, that will impact our internal financing structure. In addition, in October , 2016 the U.S. Treasury issued final Section 385 debt-equity regulations th at may also impact our internal financings . We are currently evaluating the impacts of both these measures , but, currently do not believe that they will have a material effect on our Consolidated Financial Statements. We monitor income tax developments (including, for example, the European Union’s state aid investigations) in countr ies where we conduct business . New or proposed changes to tax laws could affect our tax liabilities in the future.

Commitments and Contingencies [Abstract]
Commitments and Contingencies [Text Block]	11. Commitments and Contingencies 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 instr uments 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 difficulty in obtaining the required financial assurance instruments for our current operations. Environmental Remediation —Our accrued liability for future environmental remed iation costs at current and former plant sites and other remediation sites totaled $105 million and $106 million as of September 30, 2016 and December 31, 2015 , respectively. At September 30, 2016 , the accrued liabilities for individual sites range fr om less than $ 1 million to $22 million . The remediation expenditures are expected to occur over a number of years, and not to be concentrated in any single year. In our opinion, it is reasonably possible that losses in excess of the liabilities recorded ma y 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 r eassess 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 : Nine Months Ended September 30, Millions of dollars 2016 2015 Beginning balance $ 106 $ 106 Additional provision 3 6 Changes in estimates 10 (3) Amounts paid (16) (6) Foreign exchange effects 2 (6) Ending balance $ 105 $ 97 Access Indemnity Demand ―In December 2010, one of our subsidiaries received demand letters from affiliates of Access Industries (collectively, “Access Entities”), a more than five percent shareholder of the Company , demanding indemnity for losses, including attorney’s fees and expenses, arising out of a pending lawsuit styled Edward S. Weisfelner, as Litigation Trustee of the LB Litigation Trust v. Leonard Blavatnik, et al., Adversary Proceeding No. 09-1375 (REG), in the United States Bankruptcy Cou rt, Southern District of New York. In the Weisfelner lawsuit, the plaintiffs seek to recover from Access the return of all amounts earned by the Access Entities related to their purchase of shares of Lyondell Chemical prior to its acquisition by Basell AF S.C.A.; distributions by Basell AF S.C.A. to its shareholders before it acquired Lyondell Chemical; and management and transaction fees and expenses. A trial began in October 2016 and is currently ongoing . The Ac cess Entities have also demanded $ 100 million in management fees under a 2007 management agreement between an Access affiliate and the predecessor of LyondellBasell AF, as well as other unspecified amounts relating to advice purportedly given in connection with financing and other strategic transactions. In June 2009, an Access affiliate filed a proof of claim in Bankruptcy Court against LyondellBasell AF seeking “no less than ” $ 72 3 thousand for amounts allegedly owed under the 2007 management agreement . In April 2011, Lyondell Chemical filed an objection to the claim and brought a declaratory judgment action for a determination that the demands are not valid. The declaratory judgment action is stayed pending the outcome of the Weisfelner lawsuit. We do not believe that the 2007 management agreement is in effect or that the Company or any Company-affiliated entity owes any obligations under the management agreement, including for management fees or for indemnification. We intend to vigorously defend our posit ion in any proceedings and against any claims or demands that may be asserted. We cannot at this time estimate the reasonably possible loss or range of loss that may be incur red in the Weisfelner lawsuit ; therefore , we cannot estimate the loss that may be sought by way of indemnity. 409A Matter —Certain of the Company’s current and former executives are being audited by the Internal Revenue Service for the 2012 tax year. The IRS has issued proposed assessments of additional taxes to these individuals for wag es and penalties under Section 409A of the Internal Revenue Code. The IRS has argued that stock options awarded to the individuals in 2010 in connection with the Company’s emergence from bankruptcy should not have used the exercise price set under the bank ruptcy court approved plan of reorganization but instead should have used an exercise price based on pre-emergence trading by parties not controlled by the Company. If the individuals are unsuccessful in their defenses against these audits, or any audits f or subsequent tax years, the Company believes it is reasonably possible that it may be liable to the individual executive taxpayers for the additional amounts they may owe to the IRS as a result of the stock options allegedly not meeting the exemption from Section 409A. Any amount that may be owed by the Company is dependent on the ultimate resolution of the IRS audits, but the Company believes that such amount could range from no liability to up to $ 165 million. The Company intends to vigorously defend its compensation practices. 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/o r 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 p rovisions pertaining to third party claims relating to environmental and tax matters and various types of litigation. As of September 30, 2016 , we had not accrued any significant amounts for our indemnification obligations, and we are not aware of other c ircumstances 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 h ave a stated maximum amount and generally cover a period of five to ten years .
