Accounting Policies [Abstract]
Basis of Presentation and Major Accounting Policies	BASIS OF PRESENTATION AND MAJOR ACCOUNTING POLICIES Basis of Presentation The interim consolidated financial statements of Air Products and Chemicals, Inc. and its subsidiaries (“we,” “our,” “us,” the “Company,” “Air Products,” or “registrant”) included herein have been prepared by us, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to such rules and regulations. In our opinion, the accompanying statements reflect adjustments necessary to present fairly the financial position, results of operations, and cash flows for those periods indicated and contain adequate disclosures to make the information presented not misleading. Adjustments included herein are of a normal, recurring nature unless otherwise disclosed in the notes to the interim consolidated financial statements. These notes, unless otherwise indicated, are presented on a continuing operations basis. To fully understand the basis of presentation, the interim consolidated financial statements and related notes included herein should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended 30 September 2021 (the "2021 Form 10-K"). Results of operations for interim periods are not necessarily indicative of the results of operations for a full year. Major Accounting Policies Refer to our 2021 Form 10-K for a description of major accounting policies. There have been no significant changes to these accounting policies during the first nine months of fiscal year 2022. Segment Reorganization We reorganized our reporting segments effective 1 October 2021. Prior year segment information presented has been updated to conform with the fiscal year 2022 presentation. Refer to Note 19, Business Segment Information , for additional information. Russia's Invasion of Ukraine In March 2022, we announced our intent to divest our small industrial gas business in Russia due to Russia's invasion of Ukraine. As a result, we reclassified assets that met the held for sale criteria in our Europe segment to "Other receivables and current assets" in the second quarter of fiscal year 2022. The effect of this reclassification is excluded from our consolidated statement of cash flows for the nine months ended 30 June 2022. As of 30 June 2022, assets held for sale associated with our Russia business had a carrying value of approximately $75. Our consolidated balance sheet also includes approximately $45 as of 30 June 2022 within "Plant and equipment, net" related to a suspended project in Ukraine. Risks and Uncertainties We are subject to various risks and uncertainties, including, but not limited to, those resulting from the COVID-19 pandemic as well as from increased inflationary pressures and Russia's invasion of Ukraine. Our results of operations for the periods covered by this report were not materially impacted by these events. However, given the dynamic nature of these circumstances, uncertainty remains related to how these events may affect our business, results of operations, and overall financial performance in future periods. For example, there is uncertainty regarding our ability to recover the carrying value of our assets in Russia and Ukraine.

New Accounting Guidance

New Accounting Guidance	9 Months Ended
	Jun. 30, 2022
Accounting Standards Update and Change in Accounting Principle [Abstract]
New Accounting Guidance	NEW ACCOUNTING GUIDANCE New Accounting Guidance to be Implemented Government Assistance In November 2021, the Financial Accounting Standards Board ("FASB") issued disclosure guidance to increase the transparency of transactions an entity has with a government that are accounted for by applying a grant or contribution accounting model. This guidance is effective beginning in fiscal year 2023, with early adoption permitted. We are evaluating the impact this guidance will have on our consolidated financial statements. Acquired Revenue Contracts in a Business Combination In October 2021, the FASB issued an update for the recognition of contract assets and liabilities acquired in a business combination. Rather than recognizing such items at fair value on the acquisition date, the acquirer would measure and recognize contract assets and liabilities in accordance with ASC 606, Revenue from Contracts with Customers , as if it had originated the contract. This guidance is effective beginning in fiscal year 2024, with early adoption permitted. We are evaluating the impact this guidance will have on our consolidated financial statements. Reference Rate Reform In March 2020, the FASB issued an update to provide practical expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. This update is primarily applicable to our contracts and hedging relationships that reference the London Inter-Bank Offered Rate ("LIBOR"). The amendments may be applied to impacted contracts and hedges prospectively through 31 December 2022. To date, we have had no impacts on our hedging relationships related to reference rate reform. We will continue to evaluate the impact this guidance could have on our consolidated financial statements.

Acquisitions

Acquisitions	9 Months Ended
	Jun. 30, 2022
Business Combinations [Abstract]
Acquisitions	ACQUISITIONS Fiscal Year 2021 Gain on Exchange With Joint Venture Partner We previously held a 50% ownership interest in Tyczka Industrie-Gases GmbH ("TIG"), a joint venture in Germany with the Tyczka Group that was primarily a merchant gases business. We accounted for this arrangement as an equity method investment in our former Industrial Gases – EMEA segment. Effective 23 February 2021 (the "acquisition date"), TIG was separated into two businesses, one of which we acquired on a 100% basis. Our partner paid us $10.8 to acquire the other business. The exchange resulted in a gain of $36.8 ($27.3 after-tax), which is reflected as “Gain on exchange with joint venture partner” on our consolidated income statements for the nine months ended 30 June 2021. The gain included $12.7 from the revaluation of our previously held equity interest in the portion of the business that we retained and $24.1 from the sale of our equity interest in the remaining business. The gain was not recorded in segment results. We estimated an acquisition date fair value of $15.4 for our previously held equity interest in the acquired portion of the business using a market approach, which considered historical earnings and the application of a market-based multiple derived from comparable transactions. We accounted for the acquisition as a business combination. The results of this business are consolidated within our Europe segment.

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	REVENUE RECOGNITION The majority of our revenue is generated from our sale of gas customers within the regional industrial gases segments. We distribute gases through either our on-site or merchant supply mode depending on various factors, including the customer's volume requirements and location. The Corporate and other segment serves our sale of equipment customers. Disaggregation of Revenue The tables below present our consolidated sales disaggregated by supply mode for each of our reporting segments for the three and nine months ended 30 June 2022 and 2021. We believe this presentation best depicts the nature, timing, type of customer, and contract terms for our sales.

This amount includes fixed-charge contract provisions associated with our on-site and sale of equipment supply modes. We estimate that approximately half of this revenue will be recognized over the next five years and the balance thereafter. Expected revenue associated with new on-site plants that are not yet on stream is excluded from this amount. In addition, this amount excludes consideration associated with contracts having an expected duration of less than one year and variable consideration for which we recognize revenue at the amount to which we have the right to invoice, including energy pass-through costs. In the future, actual amounts will differ due to events outside of our control, including, but not limited to, inflationary price escalations; currency exchange rates; and amended, terminated, or renewed contracts.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	DISCONTINUED OPERATIONS Income from discontinued operations, net of tax, was $8.2 and $18.5 for the three and nine months ended 30 June 2021, respectively. In the third quarter of fiscal year 2021, we recorded a net tax benefit of $8.2 upon release of tax liabilities related to uncertain tax positions associated with our former Energy-from-Waste ("EfW") business. These liabilities were established in 2016 and released after expiration of the statute of limitations. Additionally, we recorded a tax benefit of $10.3 in the first quarter of fiscal year 2021 primarily from the settlement of a state tax appeal related to the gain on the sale of our former Performance Materials Division in fiscal year 2017. Our consolidated statement of cash flows for the nine months ended 30 June 2021 includes $6.7 received as part of the settlement.

Equity Method Investments and Joint Ventures [Abstract]
Equity Affiliates	EQUITY AFFILIATES Equity Affiliate Investment in Jazan Integrated Gasification and Power Company (“JIGPC”) On 27 October 2021, we made an initial investment of $1.6 billion in Jazan Integrated Gasification and Power Company ("JIGPC"). JIGPC is a joint venture with Saudi Aramco Power Company (a subsidiary of Aramco), ACWA Power, and Air Products Qudra in the Jazan Economic City, Saudi Arabia. Our investment represents a 55% interest in the joint venture, of which 4% is attributable to the non-controlling partner of Air Products Qudra. The $1.6 billion investment, which includes approximately $130 from the non-controlling partner, is primarily in the form of shareholder loans that qualify as in-substance common stock in the joint venture. We expect to make an additional investment in JIGPC of approximately $1 billion in 2023. We determined JIGPC is a variable interest entity for which we are not the primary beneficiary as we do not have the power to direct the activities that are most significant to the economic performance of the joint venture. Instead, these activities, including plant dispatch, operating and maintenance decisions, budgeting, capital expenditures, and financing, require unanimous approval of the owners or are controlled by the customer. Since we have the ability to exercise significant influence in the joint venture, we accounted for our investment in JIGPC under the equity method within the Middle East and India segment. Pursuant to the joint venture agreement, cash distributions include preferred distributions to some shareholders. We record our share of income considering current distributions and projections of cash available to Air Products over the life of the venture. As of 30 June 2022, the carrying value of our investment totaled $1,743.9 and is presented as “Investments in and advances to equity affiliates” on our consolidated balance sheet. Our loss exposure is limited to our investment in the joint venture. JIGPC Joint Venture On 27 September 2021, JIGPC signed definitive agreements for the acquisition of project assets from Aramco for $12 billion and entered into related project financing for the purchase. JIGPC will complete the acquisition of the project assets, which include power blocks, gasifiers, air separation units, syngas cleanup assets, and utilities, in two phases. The first phase was completed on 27 October 2021 for $7 billion. The second phase is expected to be completed in 2023. JIGPC will commission, operate, and maintain the project assets to supply electricity, steam, hydrogen, and utilities to Aramco’s refinery and terminal complex under a 25-year agreement, which commenced in the first quarter of fiscal year 2022. JIGPC accounted for the asset transfer as a financing. Accordingly, the joint venture recorded a financing receivable upon acquisition and will recognize financing income over the supply term. Jazan Gas Project Company Jazan Gas Project Company (“JGPC”), a joint venture between Air Products and ACWA Holding, entered into a 20-year oxygen and nitrogen supply agreement in 2015 to supply Aramco’s oil refinery and power plant in Jazan, Saudi Arabia. We own 26% of the joint venture. In October 2021, the supply agreement between JGPC and Aramco was terminated, and JGPC sold its air separation units to Aramco. We initially sold these assets to JGPC and deferred revenue and profit equal to our ownership percentage in the joint venture. With the termination of the supply agreement and sale of the air separation units complete, we recognized the remaining deferred profit, net of other project finalization costs, in equity affiliates’ income in the first quarter of fiscal year 2022.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	FINANCIAL INSTRUMENTS Currency Price Risk Management Our earnings, cash flows, and financial position are exposed to foreign currency risk from foreign currency-denominated transactions and net investments in foreign operations. It is our policy to seek to minimize our cash flow volatility from changes in currency exchange rates. This is accomplished by identifying and evaluating the risk that our cash flows will change in value due to changes in exchange rates and by executing strategies necessary to manage such exposures. Our objective is to maintain economically balanced currency risk management strategies that provide adequate downside protection. Forward Exchange Contracts We enter into forward exchange contracts to reduce the cash flow exposure to foreign currency fluctuations associated with highly anticipated cash flows and certain firm commitments, such as the purchase of plant and equipment. We also enter into forward exchange contracts to hedge the cash flow exposure on intercompany loans and third-party debt. This portfolio of forward exchange contracts consists primarily of Euros and U.S. Dollars. The maximum remaining term of any forward exchange contract currently outstanding and designated as a cash flow hedge at 30 June 2022 is 4.0 years. Forward exchange contracts are also used to hedge the value of investments in certain foreign subsidiaries and affiliates by creating a liability in a currency in which we have a net equity position. The primary currency pair in this portfolio of forward exchange contracts is Euros and U.S. Dollars. We also utilize forward exchange contracts that are not designated as hedges. These contracts are used to economically hedge foreign currency-denominated monetary assets and liabilities, primarily working capital. The primary objective of these forward exchange contracts is to protect the value of foreign currency-denominated monetary assets and liabilities from the effects of volatility in foreign exchange rates that might occur prior to their receipt or settlement. This portfolio of forward exchange contracts consists of many different foreign currency pairs, with a profile that changes from time to time depending on our business activity and sourcing decisions. The table below summarizes our outstanding currency price risk management instruments: 30 June 2022 30 September 2021 US$ Years US$ Years Forward Exchange Contracts: Cash flow hedges $4,640.8 0.8 $3,465.2 0.6 Net investment hedges 572.4 2.3 638.0 3.0 Not designated 486.7 0.2 692.6 0.1 Total Forward Exchange Contracts $5,699.9 0.9 $4,795.8 0.8 The increase in the notional value of cash flow hedges from 30 September 2021 to 30 June 2022 is primarily due to the origination of forward exchange contracts that hedge forecasted foreign currency costs for capital projects. We also use foreign currency-denominated debt to hedge the foreign currency exposures of our net investment in certain foreign subsidiaries. The designated foreign currency-denominated debt and related accrued interest was €1,278.1 million ($1,339.6) at 30 June 2022 and €1,297.5 million ($1,502.6) at 30 September 2021. The designated foreign currency-denominated debt is presented within "Long-term debt" on the consolidated balance sheets. Debt Portfolio Management It is our policy to identify, on a continuing basis, the need for debt capital and to evaluate the financial risks inherent in funding the Company with debt capital. Reflecting the result of this ongoing review, our debt portfolio and hedging program are managed with the intent to (1) reduce funding risk with respect to borrowings made by us to preserve our access to debt capital and provide debt capital as required for funding and liquidity purposes, and (2) manage the aggregate interest rate risk and the debt portfolio in accordance with certain debt management parameters. Interest Rate Management Contracts We enter into interest rate swaps to change the fixed/variable interest rate mix of our debt portfolio in order to maintain the percentage of fixed- and variable-rate debt within the parameters set by management. In accordance with these parameters, the agreements are used to manage interest rate risks and costs inherent in our debt portfolio. Our interest rate management portfolio generally consists of fixed-to-floating interest rate swaps (which are designated as fair value hedges), pre-issuance interest rate swaps and treasury locks (which hedge the interest rate risk associated with anticipated fixed-rate debt issuances and are designated as cash flow hedges), and floating-to-fixed interest rate swaps (which are designated as cash flow hedges). As of 30 June 2022, the outstanding interest rate swaps were denominated in U.S. Dollars. The notional amount of the interest rate swap agreements is equal to or less than the designated debt being hedged. When interest rate swaps are used to hedge variable-rate debt, the indices of the swaps and the debt to which they are designated are the same. It is our policy not to enter into any interest rate management contracts which lever a move in interest rates on a greater than one-to-one basis. Cross Currency Interest Rate Swap Contracts We enter into cross currency interest rate swap contracts when our risk management function deems necessary. These contracts may entail both the exchange of fixed- and floating-rate interest payments periodically over the life of the agreement and the exchange of one currency for another currency at inception and at a specified future date. The contracts are used to hedge either certain net investments in foreign operations or non-functional currency cash flows related to intercompany loans. The current cross currency interest rate swap portfolio consists of fixed-to-fixed swaps primarily between the U.S. Dollar and each of the Chinese Renminbi, Indian Rupee, and Chilean Peso. The table below summarizes our outstanding interest rate management contracts and cross currency interest rate swaps: 30 June 2022 30 September 2021 US$ Average Average Years US$ Average Average Years Interest rate swaps $800.0 Various 1.64 % 5.3 $200.0 LIBOR 2.76 % 0.1 Cross currency interest rate swaps $214.4 4.34 % 3.15 % 1.5 $210.2 4.32 % 3.14 % 2.2 Cross currency interest rate swaps $981.9 4.92 % 2.93 % 2.1 $1,005.7 4.98 % 2.93 % 2.7 Cross currency interest rate swaps $— — % — % 0.0 $4.2 5.39 % 3.54 % 2.2 The table below provides the amounts recorded on the consolidated balance sheet related to cumulative basis adjustments for fair value hedges: Carrying amounts of hedged item Cumulative hedging adjustment, included in carrying amount 30 June 30 September 30 June 30 September Balance Sheet Location 2022 2021 2022 2021 Current portion of long-term debt $— $400.5 $— $0.5 Long-term debt 2,044.7 — (44.9) — The table below summarizes the fair value and balance sheet location of our outstanding derivatives: Balance Sheet 30 June 30 September Balance Sheet 30 June 30 September Location 2022 2021 Location 2022 2021 Derivatives Designated as Hedging Instruments: Forward exchange contracts Other receivables and current assets $55.2 $35.1 Payables and accrued liabilities $117.8 $57.2 Interest rate management contracts Other receivables and current assets 20.9 16.0 Payables and accrued liabilities 7.8 5.2 Forward exchange contracts Other noncurrent assets 26.3 5.5 Other noncurrent liabilities 12.3 25.2 Interest rate management contracts Other noncurrent assets 29.6 18.1 Other noncurrent liabilities 73.7 27.5 Total Derivatives Designated as Hedging Instruments $132.0 $74.7 $211.6 $115.1 Derivatives Not Designated as Hedging Instruments: Forward exchange contracts Other receivables and current assets 5.6 8.7 Payables and accrued liabilities 3.5 6.4 Total Derivatives Not Designated as Hedging Instruments $5.6 $8.7 $3.5 $6.4 Total Derivatives $137.6 $83.4 $215.1 $121.5 Refer to Note 10, Fair Value Measurements , which defines fair value, describes the method for measuring fair value, and provides additional disclosures regarding fair value measurements.

The cash flows related to all derivative contracts are reported in the operating activities section of the consolidated statements of cash flows. Credit Risk-Related Contingent Features Certain derivative instruments are executed under agreements that require us to maintain a minimum credit rating with both Standard & Poor’s and Moody’s. If our credit rating falls below this threshold, the counterparty to the derivative instruments has the right to request full collateralization on the derivatives’ net liability position. The net liability position of derivatives with credit risk-related contingent features was $86.9 and $53.4 as of 30 June 2022 and 30 September 2021, respectively. Because our current credit rating is above the various pre-established thresholds, no collateral has been posted on these liability positions. Counterparty Credit Risk Management We execute financial derivative transactions with counterparties that are highly rated financial institutions, all of which are investment grade at this time. Some of our underlying derivative agreements give us the right to require the institution to post collateral if its credit rating falls below the pre-established thresholds with Standard & Poor’s or Moody’s. The collateral that the counterparties would be required to post was $68.3 and $38.1 as of 30 June 2022 and 30 September 2021, respectively. No financial institution is required to post collateral at this time as all have credit ratings at or above threshold.

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair value is defined as an exit price, or the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels as follows: Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 — Inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the asset or liability. Level 3 — Inputs that are unobservable for the asset or liability based on our own assumptions about the assumptions market participants would use in pricing the asset or liability. The methods and assumptions used to measure the fair value of financial instruments are as follows: Short-term Investments Short-term investments primarily include time deposits with original maturities greater than three months and less than one year. We estimated the fair value of our short-term investments, which approximates carrying value as of the balance sheet date, using Level 2 inputs within the fair value hierarchy. Level 2 measurements were based on current interest rates for similar investments with comparable credit risk and time to maturity. Derivatives The fair value of our interest rate management contracts and forward exchange contracts are quantified using the income approach and are based on estimates using standard pricing models. These models consider the value of future cash flows as of the balance sheet date, discounted to a present value using discount factors that match both the time to maturity and currency of the underlying instruments. These standard pricing models utilize inputs that are derived from or corroborated by observable market data such as interest rate yield curves as well as currency spot and forward rates; therefore, the fair value of our derivatives is classified as a Level 2 measurement. On an ongoing basis, we randomly test a subset of our valuations against valuations received from the transaction’s counterparty to validate the accuracy of our standard pricing models. Counterparties to these derivative contracts are highly rated financial institutions. Refer to Note 9, Financial Instruments , for a description of derivative instruments, including details related to the balance sheet line classifications. Long-term Debt, Including Related Party The fair value of our debt is based on estimates using standard pricing models that consider the value of future cash flows as of the balance sheet date, discounted to a present value using discount factors that match both the time to maturity and currency of the underlying instruments. These standard valuation models utilize observable market data such as interest rate yield curves and currency spot rates; therefore, the fair value of our debt is classified as a Level 2 measurement. We generally perform the computation of the fair value of these instruments. The carrying values and fair values of financial instruments were as follows: 30 June 2022 30 September 2021 Carrying Value Fair Value Carrying Value Fair Value Assets Derivatives Forward exchange contracts $87.1 $87.1 $49.3 $49.3 Interest rate management contracts 50.5 50.5 34.1 34.1 Liabilities Derivatives Forward exchange contracts $133.6 $133.6 $88.8 $88.8 Interest rate management contracts 81.5 81.5 32.7 32.7 Long-term debt, including current portion and related party 7,378.9 6,696.5 7,634.8 7,812.2 The carrying amounts reported on the consolidated balance sheets for cash and cash items, short-term investments, trade receivables, payables and accrued liabilities, accrued income taxes, and short-term borrowings approximate fair value due to the short-term nature of these instruments. Accordingly, these items have been excluded from the above table.

Debt	DEBT Debt Repayment In November 2021, we repaid a 3.0% Senior Note of $400, plus interest, on its maturity date. Credit Facilities 2021 Credit Agreement On 31 March 2021, we entered into a five-year $2,500 revolving credit agreement maturing 31 March 2026 with a syndicate of banks (the “2021 Credit Agreement”), under which senior unsecured debt is available to us and certain of our subsidiaries. On 31 March 2022, we amended the 2021 Credit Agreement to exercise our option to increase the maximum borrowing capacity to $2,750 and transition the benchmark rate from LIBOR to the Secured Overnight Financing Rate ("SOFR"). All other terms remain unchanged from the original agreement. No borrowings were outstanding under the 2021 Credit Agreement as of 30 June 2022.

Retirement Benefits	RETIREMENT BENEFITS The components of net periodic (benefit) cost for our defined benefit pension plans for the three and nine months ended 30 June 2022 and 2021 were as follows: Pension Benefits 2022 2021 Three Months Ended 30 June U.S. International U.S. International Service cost $4.6 $5.3 $5.3 $5.9 Interest cost 18.4 7.1 17.2 6.4 Expected return on plan assets (42.0) (16.6) (48.6) (21.2) Prior service cost amortization 0.3 — 0.3 — Actuarial loss amortization 16.6 3.6 19.6 4.8 Settlements 3.1 — — 0.5 Other — 0.2 — 0.3 Net Periodic (Benefit) Cost $1.0 ($0.4) ($6.2) ($3.3) Pension Benefits 2022 2021 Nine Months Ended 30 June U.S. International U.S. International Service cost $13.8 $16.5 $16.0 $17.5 Interest cost 55.2 22.3 51.7 18.8 Expected return on plan assets (126.2) (51.9) (145.9) (62.4) Prior service cost amortization 0.9 — 0.9 — Actuarial loss amortization 49.9 11.3 58.9 14.2 Settlements 4.9 0.2 — 0.5 Other — 1.2 — 0.8 Net Periodic (Benefit) Cost ($1.5) ($0.4) ($18.4) ($10.6) Our service costs are primarily included within "Cost of sales" and "Selling and administrative" on our consolidated income statements. The amount of service costs capitalized in the first nine months of fiscal years 2022 and 2021 were not material. The non-service related impacts, including pension settlement losses, are presented outside operating income within "Other non-operating income (expense), net." For the nine months ended 30 June 2022 and 2021, our cash contributions to funded pension plans and benefit payments under unfunded pension plans were $31.7 and $34.0, respectively. Total contributions for fiscal year 2022 are expected to be approximately $40 to $50. During fiscal year 2021, total contributions were $44.6.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Litigation We are involved in various legal proceedings, including commercial, competition, environmental, intellectual property, regulatory, product liability, and insurance matters. We do not currently believe there are any legal proceedings, individually or in the aggregate, that are reasonably possible to have a material impact on our financial condition, results of operations, or cash flows. In September 2010, the Brazilian Administrative Council for Economic Defense ("CADE") issued a decision against our Brazilian subsidiary, Air Products Brasil Ltda., and several other Brazilian industrial gas companies for alleged anticompetitive activities. CADE imposed a civil fine of R$179.2 million (approximately $34 at 30 June 2022) on Air Products Brasil Ltda. This fine was based on a recommendation by a unit of the Brazilian Ministry of Justice, following an investigation beginning in 2003, which alleged violation of competition laws with respect to the sale of industrial and medical gases. The fines are based on a percentage of our total revenue in Brazil in 2003. We have denied the allegations made by the authorities and filed an appeal in October 2010 with the Brazilian courts. On 6 May 2014, our appeal was granted and the fine against Air Products Brasil Ltda. was dismissed. CADE has appealed that ruling and the matter remains pending. We, with advice of our outside legal counsel, have assessed the status of this matter and have concluded that, although an adverse final judgment after exhausting all appeals is possible, such a judgment is not probable. As a result, no provision has been made in the consolidated financial statements. In the event of an adverse final judgment, we estimate the maximum possible loss to be the full amount of the fine of R$179.2 million (approximately $34 at 30 June 2022) plus interest accrued thereon until final disposition of the proceedings. Additionally, Winter Storm Uri, a severe winter weather storm in the U.S. Gulf Coast in February 2021, disrupted our operations and caused power and natural gas prices to spike significantly in Texas. We remain in litigation of a dispute regarding energy management services related to the impact of this event, and other disputes may arise from such power price increases. In addition, legislative action may affect power supply and energy management charges. While it is reasonably possible that we could incur additional costs related to power supply and energy management services in Texas related to the winter storm, it is too early to estimate potential losses, if any, given significant unknowns resulting from the unusual nature of this event. Environmental In the normal course of business, we are involved in legal proceedings under the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA," the federal Superfund law), Resource Conservation and Recovery Act ("RCRA"), and similar state and foreign environmental laws relating to the designation of certain sites for investigation or remediation. Presently, there are 32 sites on which a final settlement or remediation has not been achieved where we, usually along with others, have been designated a potentially responsible party by environmental authorities or are otherwise engaged in investigation or remediation, including cleanup activity at certain of our current and former manufacturing sites. We continually monitor these sites for which we have environmental exposure. Accruals for environmental loss contingencies are recorded when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. The consolidated balance sheets at 30 June 2022 and 30 September 2021 included an accrual of $72.3 and $76.7, respectively, primarily as part of other noncurrent liabilities. The environmental liabilities will be paid over a period of up to 30 years. We estimate the exposure for environmental loss contingencies to range from $71 to a reasonably possible upper exposure of $85 as of 30 June 2022. Actual costs to be incurred at identified sites in future periods may vary from the estimates, given inherent uncertainties in evaluating environmental exposures. Using reasonably possible alternative assumptions of the exposure level could result in an increase to the environmental accrual. Due to the inherent uncertainties related to environmental exposures, a significant increase to the reasonably possible upper exposure level could occur if a new site is designated, the scope of remediation is increased, a different remediation alternative is identified, or a significant increase in our proportionate share occurs. We do not expect that any sum we may have to pay in connection with environmental matters in excess of the amounts recorded or disclosed above would have a material adverse impact on our financial position or results of operations in any one year. Pace At 30 June 2022, $38.5 of the environmental accrual was related to the Pace facility. In 2006, we sold our Amines business, which included operations at Pace, Florida, and recognized a liability for retained environmental obligations associated with remediation activities at Pace. We are required by the Florida Department of Environmental Protection ("FDEP") and the United States Environmental Protection Agency ("USEPA") to continue our remediation efforts. We recognized a before-tax expense of $42 in fiscal year 2006 in results from discontinued operations and recorded an environmental accrual of $42 in continuing operations on the consolidated balance sheets. During the second quarter of fiscal year 2020, we completed an updated cost review of the environmental remediation status at the Pace facility. The review was completed in conjunction with requirements to maintain financial assurance per the Consent Order issued by the FDEP discussed below. Based on our review, we expect ongoing activities to continue for 30 years. Additionally, we will require near-term spending to install new groundwater recovery wells and ancillary equipment, in addition to future capital to consider the extended time horizon for remediation at the site. As a result of these changes, we increased our environmental accrual for this site by $19 in continuing operations on the consolidated balance sheets and recognized a before-tax expense of $19 in results from discontinued operations in the second quarter of fiscal year 2020. There have been no significant changes to the estimated exposure range related to the Pace facility since the second quarter of fiscal year 2020. We have implemented many of the remedial corrective measures at the Pace facility required under 1995 Consent Orders issued by the FDEP and the USEPA. Contaminated soils have been bioremediated, and the treated soils have been secured in a lined on-site corrective action management unit. Several groundwater recovery systems have been installed to contain and remove contamination from groundwater. We completed an extensive assessment of the site to determine the efficacy of existing measures, what additional corrective measures may be needed, and whether newer remediation technologies that were not available in the 1990s might be suitable to more quickly and effectively remediate groundwater. Based on assessment results, we completed a focused feasibility study that has identified alternative approaches that may more effectively remove contaminants. We continue to review alternative remedial approaches with the FDEP and have completed additional field work during 2021 to support the design of an improved groundwater recovery network with the objective of targeting areas of higher contaminant concentration and avoiding areas of high groundwater iron which has proven to be a significant operability issue for the project. The design of the optimized recovery system will likely be finalized in fiscal year 2023 with construction to begin thereafter. In the first quarter of 2015, we entered into a new Consent Order with the FDEP requiring us to continue our remediation efforts at the Pace facility, along with the completion of a cost review every 5 years. Piedmont At 30 June 2022, $7.7 of the environmental accrual was related to the Piedmont site. On 30 June 2008, we sold our Elkton, Maryland, and Piedmont, South Carolina, production facilities and the related North American atmospheric emulsions and global pressure sensitive adhesives businesses. In connection with the sale, we recognized a liability for retained environmental obligations associated with remediation activities at the Piedmont site. This site is under active remediation for contamination caused by an insolvent prior owner. We are required by the South Carolina Department of Health and Environmental Control ("SCDHEC") to address both contaminated soil and groundwater. Numerous areas of soil contamination have been addressed, and contaminated groundwater is being recovered and treated. The SCDHEC issued its final approval to the site-wide feasibility study on 13 June 2017 and the Record of Decision for the site on 27 June 2018, after which we signed a Consent Agreement Amendment memorializing our obligations to complete the cleanup of the site. Remediation has started in accordance with the design, which includes in-situ chemical oxidation treatment, as well as the installation of a soil vapor extraction system to remove volatile organic compounds from the unsaturated soils beneath the impacted areas of the plant. We estimate that source area remediation and groundwater recovery and treatment will continue through 2029. Thereafter, we expect this site to go into a state of monitored natural attenuation through 2047. We recognized a before-tax expense of $24 in 2008 as a component of income from discontinued operations and recorded an environmental liability of $24 in continuing operations on the consolidated balance sheets. There have been no significant changes to the estimated exposure. Pasadena At 30 June 2022, $10.8 of the environmental accrual was related to the Pasadena site. During the fourth quarter of 2012, management committed to permanently shutting down our polyurethane intermediates ("PUI") production facility in Pasadena, Texas. In shutting down and dismantling the facility, we have undertaken certain obligations related to soil and groundwater contaminants. We have been pumping and treating groundwater to control off-site contaminant migration in compliance with regulatory requirements and under the approval of the Texas Commission on Environmental Quality ("TCEQ"). We estimate that the pump and treat system will continue to operate until 2042. We continue to perform additional work to address other environmental obligations at the site. This additional work includes remediating, as required, impacted soils, investigating groundwater west of the former PUI facility, continuing post closure care for two closed RCRA surface impoundment units, and maintaining engineering controls. Additionally, we have conducted an interim corrective action to treat impacted soils as recommended in the TCEQ 2019 Annual Report. In 2012, we estimated the total exposure at this site to be $13. There have been no significant changes to the estimated exposure. Unconditional Purchase Obligations Our unconditional purchase obligations related to helium and rare gases decreased from approximately $8.3 billion as of 30 September 2021 to approximately $6.9 billion as of 30 June 2022 due to the termination of a supply contract. The majority of our obligations occur after fiscal year 2027. Helium purchases include crude feedstock supply to helium refining plants in North America as well as refined helium purchases from sources around the world.

Share-based Payment Arrangement [Abstract]
Share-Based Compensation	SHARE-BASED COMPENSATION Our outstanding share-based compensation programs include deferred stock units and stock options. During the nine months ended 30 June 2022, we granted market-based and time-based deferred stock units. Under all programs, the terms of the awards are fixed at the grant date. We issue shares from treasury stock upon the payout of deferred stock units and the exercise of stock options. As of 30 June 2022, there were 1.3 million shares available for future grant under our Long-Term Incentive Plan ("LTIP"). Share-based compensation cost recognized on the consolidated income statements is summarized below: Three Months Ended Nine Months Ended 30 June 30 June 2022 2021 2022 2021 Before-tax share-based compensation cost $10.7 $12.2 $38.0 $34.6 Income tax benefit (2.6) (3.2) (9.3) (8.6) After-tax share-based compensation cost $8.1 $9.0 $28.7 $26.0 Before-tax share-based compensation cost is primarily included in "Selling and administrative" on our consolidated income statements. The amount of share-based compensation cost capitalized in the first nine months of fiscal years 2022 and 2021 was not material. Deferred Stock Units During the nine months ended 30 June 2022, we granted 74,364 market-based deferred stock units. The market-based deferred stock units are earned over the performance period beginning 1 October 2021 and ending 30 September 2024, conditioned on the level of our total shareholder return in relation to a defined peer group over the three-year performance period. The market-based deferred stock units had an estimated grant-date fair value of $427.23 per unit, which was estimated using a Monte Carlo simulation model. The model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the grant and calculates the fair value of the awards. We generally expense the grant-date fair value of these awards on a straight-line basis over the vesting period. The calculation of the fair value of market-based deferred stock units used the following assumptions: Expected volatility 30.5 % Risk-free interest rate 0.8 % Expected dividend yield 2.1 % In addition, during the nine months ended 30 June 2022, we granted 117,686 time-based deferred stock units at a weighted average grant-date fair value of $279.64.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Effective Tax Rate The effective tax rate equals the income tax provision divided by income from continuing operations before taxes. Our effective tax rate was 18.6% and 18.1% for the three and nine months ended 30 June 2022, respectively. Our effective tax rate was 16.3% and 18.6% for the three and nine months ended 30 June 2021, respectively. Cash Paid for Taxes (Net of Cash Refunds) Income tax payments, net of refunds, were $341.3 and $284.8 for the nine months ended 30 June 2022 and 2021, respectively. Fiscal year 2021 reflects an income tax refund of $6.7 that is related to cash provided by discontinued operations. Unrecognized Tax Benefits In the third quarter of fiscal year 2021, we released unrecognized tax benefits upon expiration of the statute of limitations on uncertain tax positions. As a result, we recorded a net tax benefit of $21.5, including interest, as a component of continuing operations. This included the impact from the release of reserves associated with a 2017 tax election related to a non-U.S. subsidiary. In addition, we recorded a net tax benefit of $8.2 as a component of discontinued operations for the release of reserves related to our former EfW business.

Disclosure Text Block Supplement [Abstract]
Supplemental Information	SUPPLEMENTAL INFORMATION NEOM Green Hydrogen Project In the fourth quarter of fiscal year 2020, we announced the NEOM Green Hydrogen Project (the "NEOM project”), a multi-billion dollar green hydrogen-based ammonia production facility powered by renewable energy located in the NEOM city of the Kingdom of Saudi Arabia. We, along with our joint venture partners, ACWA Power and NEOM Company, are equal owners in the newly formed NEOM Green Hydrogen Company joint venture (“NGHC”) that will develop, construct, own, operate, and finance the NEOM project. The NEOM project is expected to be financed through non-recourse project financing and the partners’ investments. During the third quarter of fiscal year 2022, we entered into an agreement with NGHC under which we commenced construction of the NEOM project. In addition, we executed an agreement with NGHC under which we will be the exclusive offtaker of the NEOM project under a long-term take-if-tendered agreement. The NEOM project is expected to be onstream in 2026. We intend to transport green ammonia around the world to be dissociated to produce green hydrogen, primarily for the transportation market. Air Products has one-third of the voting interests in the NGHC joint venture; however, substantially all the activities of the joint venture involve or are conducted on behalf of Air Products. Since we have disproportionately few voting rights relative to our economic interests in the joint venture, we determined that NGHC is a variable interest entity. In addition, we determined that we are the primary beneficiary of the NEOM project since we have the power to unilaterally direct certain significant activities, including key design and construction decisions, and we share power with our joint venture partners related to other activities that are significant to the economic performance of NGHC. Therefore, we consolidated NGHC within the Middle East and India segment beginning in the third quarter of fiscal year 2022. As of 30 June 2022, our consolidated balance sheet includes the following balances from the consolidation of NGHC: $258 in "Cash and cash items," $32 in "Other receivables and current assets," $144 in "Plant and equipment, net," $270 in "Long-term debt – related party," and $29 in "Noncontrolling interests." Related Party Transactions We have related party sales to some of our equity affiliates and joint venture partners as well as other income primarily from fees charged for use of Air Products' patents and technology. Sales to and other income from related parties totaled approximately $75 and $200 for the three and nine months ended 30 June 2022, respectively, and $40 and $130 for the three and nine months ended 30 June 2021, respectively. Sales agreements with related parties include terms that are consistent with those that we believe would have been negotiated at an arm’s length with an independent party. As of 30 June 2022 and 30 September 2021, our consolidated balance sheets included related party trade receivables of approximately $70 and $90, respectively. Total debt owed to related parties, including the current portion, was $620.6 and $358.4 as of 30 June 2022 and 30 September 2021, respectively. Our related party debt includes loans with joint venture partners, including Lu’An Clean Energy Company, as well as shareholder loans associated with the NEOM project discussed above. Facility Closure During the second quarter of fiscal year 2021, we recorded a charge of $23.2 primarily for a noncash write-down of assets associated with a contract termination in the Americas segment. This charge is reflected as "Facility closure" on our consolidated income statements for the nine months ended 30 June 2021 and was not recorded in segment results. Changes in Estimates Changes in estimates on projects accounted for under the cost incurred input method are recognized as a cumulative adjustment for the inception-to-date effect of such change. We recorded changes to project cost estimates that unfavorably impacted operating income by approximately $30 and $26 in the first nine months of fiscal year 2022 and 2021, respectively. Our changes in estimates would not have significantly impacted amounts recorded in prior years. Lessee Accounting During the nine months ended 30 June 2022, we recorded noncash right-of-use asset additions of approximately $220, primarily for operating leases that had not yet commenced as of 30 September 2021.
