Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements included herein are unaudited and have been prepared following the requirements of the Securities and Exchange Commission (the "SEC") and accounting principles generally accepted in the United States of America ("U.S. GAAP") for interim reporting. Under these rules, certain footnotes and other financial information that are normally required for annual financial statements can be condensed or omitted. These statements include all adjustments, consisting only of normal, recurring adjustments, necessary for a fair presentation of the financial position and shareholders' equity of PPG as of June 30, 2024 and the results of its operations and cash flows for the three and six months ended June 30, 2024 and 2023. All intercompany balances and transactions have been eliminated. Material subsequent events are evaluated through the report issuance date and disclosed where applicable. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in PPG's 2023 Annual Report on Form 10-K (the "2023 Form 10-K"). Net sales, expenses, assets and liabilities can vary during each quarter of the year. Accordingly, the results of operations for the three and six months ended June 30, 2024 and the trends in these unaudited condensed consolidated financial statements may not necessarily be indicative of the results to be expected for the full year. Certain prior period amounts have been reclassified to conform to the current period presentation. These reclassifications had no impact on our previously reported Net income, total assets, cash flows or shareholders’ equity.

New Accounting Standards

New Accounting Standards	Jun. 30, 2024
Accounting Policies [Abstract]
New Accounting Standards	New Accounting Standards Recently Adopted Accounting Standards Effective January 1, 2024, PPG adopted Accounting Standards Update ("ASU") No. 2023-02, "Investment - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method." This ASU permits reporting entities to elect to account for tax equity investments under the proportional amortization method, regardless of the tax credit program from which the income tax credits are received, if certain conditions are met. Adoption of this ASU did not have a material impact on PPG's consolidated financial position, results of operations or cash flows. Recently Issued Accounting Standards In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2023-07 “Improvements to Reportable Segment Disclosures (Topic 280)”. This ASU updates current reportable segment disclosure requirements to require disclosures of significant reportable segment expenses that are regularly provided to the Chief Operating Decision Maker (“CODM”) and included within each reported measure of a segment's profit or loss. This ASU also requires disclosure of the title and position of the individual identified as the CODM and an explanation of how the CODM uses the reported measures of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources. This ASU will be effective for the annual period ending December 31, 2024. Adoption of this ASU will result in additional disclosure, but it will not impact PPG’s consolidated financial position, results of operations or cash flows. In December 2023, the FASB issued ASU No. 2023-09 “Improvements to Income Tax Disclosures (Topic 740)”. This ASU updates current income tax disclosure requirements to require disclosures of specific categories of information within the effective tax rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. This ASU will be effective for the annual period ending December 31, 2025. Adoption of this ASU will result in additional disclosure, but it will not impact PPG’s consolidated financial position, results of operations or cash flows.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Identifiable Intangible Assets	Goodwill and Other Identifiable Intangible Assets The Company tests indefinite-lived intangible assets and goodwill for impairment by performing either a qualitative evaluation or a quantitative test at least annually, or more frequently if an indication of impairment arises. The qualitative evaluation is an assessment of factors to determine whether it is more likely than not that the fair value of a reporting unit or asset is less than its carrying amount. The Company did not identify an indication of goodwill impairment for any of its reporting units or an indication of impairment of any of its indefinite-lived intangible assets during the six months ended June 30, 2024. The change in the carrying amount of goodwill attributable to each reportable segment for the six months ended June 30, 2024 was as follows: ($ in millions) Performance Industrial Total January 1, 2024 $4,994 $1,206 $6,200 Acquisitions, including purchase accounting adjustments 2 — 2 Foreign currency impact (127) (28) (155) June 30, 2024 $4,869 $1,178 $6,047 As of both June 30, 2024 and December 31, 2023, accumulated goodwill impairment losses totaled $158 million.

Business Restructuring	Jun. 30, 2024
Restructuring and Related Activities [Abstract]
Business Restructuring	Business Restructuring The Company records restructuring liabilities that represent charges incurred in connection with consolidations of certain operations, including both operations from acquisitions and headcount reduction programs. These charges consist primarily of severance costs and certain other cash costs. As a result of these programs, the Company also incurs incremental non-cash accelerated depreciation expense for certain assets due to their reduced expected useful life. These charges are not allocated to the Company’s reportable business segments. Refer to Note 15, "Reportable Business Segment Information" for additional information. The following table summarizes restructuring reserve activity for the six months ended June 30, 2024 and 2023: Total Reserve ($ in millions) 2024 2023 January 1 $113 $169 Approved restructuring actions — 12 Release of prior reserves and other adjustments (a) (1) (15) Cash payments (27) (29) Foreign currency impact (2) 2 June 30 $83 $139 (a) Certain releases were recorded to reflect the current estimate of costs to complete planned business restructuring actions.

Borrowings

Borrowings	Jun. 30, 2024
Debt Disclosure [Abstract]
Borrowings	Borrowings Credit Agreements In April 2023, PPG entered into a €500 million term loan credit agreement (the "Term Loan"). The Term Loan provides the Company with the ability to increase the size of the loan by an amount not to exceed €250 million. The Term Loan contains covenants that are consistent with those in the Credit Agreement discussed below and that are usual and customary restrictive covenants for facilities of its type, which include, with specified exceptions, limitations on the Company’s ability to create liens or other encumbrances, to enter into sale and leaseback transactions and to enter into consolidations, mergers or transfers of all or substantially all of its assets. The Term Loan terminates and all amounts outstanding are payable in April 2026. In April 2023, PPG borrowed €500 million under the Term Loan. In December 2023, PPG obtained lender commitments sufficient to increase the size of the Term Loan by €250 million. In January 2024, PPG borrowed the additional €250 million. The Term Loan is denominated in euro and has been designated as a hedge of the net investment in the Company’s European operations. For more information, refer to Note 11 “Financial Instruments, Hedging Activities and Fair Value Measurements.” In March 2023, PPG amended its five-year credit agreement (the “Credit Agreement”) dated as of August 30, 2019. The amendments to the Credit Agreement replace the LIBOR-based reference interest rate option with a reference interest rate option based upon Term SOFR. The other terms of the Credit Agreement remained unchanged. In July 2023, PPG amended and restated the Credit Agreement, extending the term through July 27, 2028. The amended and restated Credit Agreement provides for a $2.3 billion unsecured revolving credit facility. The Company has the ability to increase the size of the Credit Agreement by up to an additional $750 million, subject to the receipt of lender commitments and other conditions precedent. The Company has the right, subject to certain conditions set forth in the Credit Agreement, to designate certain subsidiaries of the Company as borrowers under the Credit Agreement. In connection with any such designation, the Company is required to guarantee the obligations of any such subsidiaries under the Credit Agreement. There were no amounts outstanding under the Credit Agreement as of June 30, 2024 and December 31, 2023. Borrowings under the Credit Agreement may be made in U.S. Dollars or in euros. The Credit Agreement provides that loans will bear interest at rates based, at the Company’s option, on one of two specified base rates plus a margin based on certain formulas defined in the Credit Agreement. Additionally, the Credit Agreement contains a Commitment Fee, as defined in the Credit Agreement, on the amount of unused commitments under the Credit Agreement ranging from 0.060% to 0.125% per annum. The Credit Agreement also supports the Company’s commercial paper borrowings which are classified as long-term based on PPG’s intent and ability to refinance these borrowings on a long-term basis. There were $171 million commercial paper borrowings outstanding as of June 30, 2024 and no commercial paper borrowings outstanding as of December 31, 2023. The Credit Agreement contains usual and customary restrictive covenants for facilities of its type, which include, with specified exceptions, limitations on the Company’s ability to create liens or other encumbrances, to enter into sale and leaseback transactions and to enter into consolidations, mergers or transfers of all or substantially all of its assets. The Credit Agreement also requires the Company to maintain a ratio of Total Indebtedness to Total Capitalization, as defined in the Credit Agreement, of 60% or less; provided, that for any fiscal quarter in which the Company has made an acquisition for consideration in excess of $1 billion and for the next five fiscal quarters thereafter, the ratio of Total Indebtedness to Total Capitalization may not exceed 65% at any time. As of June 30, 2024, Total Indebtedness to Total Capitalization as defined under the Credit Agreement was 44%. The Credit Agreement contains, among other things, customary events of default that would permit the lenders to accelerate the loans, including the failure to make timely payments when due under the Credit Agreement or other material indebtedness, the failure to satisfy covenants contained in the Credit Agreement, a change in control of the Company and specified events of bankruptcy and insolvency. Other Long-term Debt Activities In March 2023, PPG's $300 million 3.2% notes matured, and the Company repaid this obligation using cash on hand. In May 2022, PPG completed a public offering of €300 million 1.875% Notes due 2025 and €700 million 2.750% Notes due 2029. These notes were issued pursuant to PPG’s existing shelf registration statement and pursuant to an indenture between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee, as supplemented (the "2022 Indenture"). The 2022 Indenture governing these notes contains covenants that limit the Company’s ability to, among other things, incur certain liens securing indebtedness, engage in certain sale-leaseback transactions, and enter into certain consolidations, mergers, conveyances, transfers or leases of all or substantially all the Company’s assets. The terms of these notes also require the Company to make an offer to repurchase Notes upon a Change of Control Triggering Event (as defined in the 2022 Indenture) at a price equal to 101% of their principal amount plus accrued and unpaid interest. The Company may issue additional debt from time to time pursuant to the Indenture. The aggregate cash proceeds from the notes, net of discounts and fees, was $1,061 million. The notes are denominated in euro and have been designated as hedges of net investments in the Company’s European operations. Refer to Note 11 “Financial Instruments, Hedging Activities and Fair Value Measurements.” for additional information. In March 2022, PPG privately placed a 15-year €50 million 1.95% fixed interest note. This note contains covenants materially consistent with the 1.875% notes discussed above. This debt arrangement is denominated in euros and has been designated as a net investment hedge of the Company's European operations. Refer to Note 11 "Financial Instruments, Hedging Activities and Fair Value Measurements" for additional information. In February 2021, PPG entered into a $2.0 billion Term Loan Credit Agreement (the "Term Loan Credit Agreement") to finance the Company’s acquisition of Tikkurila, and to pay fees, costs and expenses related thereto. The Term Loan Credit Agreement provided the Company with the ability to borrow up to an aggregate principal amount of $2.0 billion on an unsecured basis. In addition to the amounts borrowed to finance the acquisition of Tikkurila, the Term Loan Credit Agreement allowed the Company to make up to eleven additional borrowings prior to December 31, 2021, to be used for working capital and general corporate purposes. The Term Loan Credit Agreement contains covenants that are consistent with those in the Credit Agreement discussed above and that are usual and customary restrictive covenants for facilities of its type, which include, with specified exceptions, limitations on the Company’s ability to create liens or other encumbrances, to enter into sale and leaseback transactions and to enter into consolidations, mergers or transfers of all or substantially all of its assets. The Term Loan Credit Agreement was scheduled to mature and all outstanding borrowings were to be due and payable on the third anniversary of the date of the initial borrowing under the Agreement. In June 2021, PPG borrowed $700 million under Term Loan Credit Agreement to finance the Company’s acquisition of Tikkurila, and to pay fees, costs and expenses related thereto. In December 2021, PPG borrowed an additional $700 million under the Term Loan Credit Agreement. In 2022 and 2023, PPG repaid $300 million and $1.1 billion, respectively, of the Term Loan Credit Agreement using cash on hand. The Term Loan Credit Agreement was fully repaid as of December 31, 2023. Restrictive Covenants and Cross-Default Provisions As of June 30, 2024, PPG was in full compliance with the restrictive covenants under its various credit agreements, loan agreements and indentures. Additionally, the Company’s Credit Agreement contains customary cross-default provisions. These provisions provide that a default on a debt service payment of $100 million or more for longer than the grace period provided under another agreement may result in an event of default under this agreement. None of the Company’s primary debt obligations are secured or guaranteed by the Company’s affiliates. Letters of Credit and Surety Bonds

During the year, PPG management regularly updates forecasted annual pretax results for the various countries in which PPG operates based on changes in factors such as prices, shipments, product mix, raw material inflation and manufacturing operations. To the extent that actual 2024 pretax results for U.S. and foreign income or loss vary from estimates, the actual Income tax expense recognized in 2024 could be different from the forecasted amount used to estimate Income tax expense for the six months ended June 30, 2024.

Retirement Benefits [Abstract]
Pensions and Other Postretirement Benefits	Pensions and Other Postretirement Benefits In March 2023, the Company purchased group annuity contracts that transferred to third-party insurance companies pension benefit obligations for certain of the Company’s retirees in the U.S. who were receiving their monthly retirement benefit payments from the U.S. pension plan. The amount of each affected retiree’s annuity payment is equal to the amount of such individual’s pension benefit. The purchase of group annuity contracts was funded directly by the assets of the U.S. plans. By transferring the obligations and assets to the insurance companies, the Company reduced its overall pension projected benefit obligation by $309 million and recognized a non-cash Pension settlement charge of $190 million. The service cost component of net periodic pension and other postretirement benefit cost is included in Cost of sales, exclusive of depreciation and amortization, Selling, general and administrative, and Research and development, net in the accompanying condensed consolidated statement of income. Except for the Pension settlement charge in the quarter ended March 31, 2023, all other components of net periodic benefit cost are recorded in Other charges/(income), net in the accompanying condensed consolidated statement of income. Net periodic pension benefit cost and other postretirement benefit cost for the three and six months ended June 30, 2024 and 2023 was as follows: Pension Three Months Ended Six Months Ended ($ in millions) 2024 2023 2024 2023 Service cost $2 $2 $4 $4 Interest cost 26 24 52 55 Expected return on plan assets (27) (24) (54) (55) Amortization of actuarial losses 5 3 11 10 Settlements 8 1 8 191 Net periodic benefit cost $14 $6 $21 $205 Other Postretirement Benefits Three Months Ended Six Months Ended ($ in millions) 2024 2023 2024 2023 Service cost $1 $1 $2 $2 Interest cost 6 6 12 13 Amortization of actuarial gains (1) (1) (1) (1) Amortization of prior service credit — (1) (2) (3) Net periodic benefit cost $6 $5 $11 $11 Net periodic pension cost was lower for the six months ended June 30, 2024 compared to 2023 primarily due to the Pension settlement charge recognized in the first quarter 2023.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments, Hedging Activities and Fair Value Measurements	Financial Instruments, Hedging Activities and Fair Value Measurements Financial instruments include cash and cash equivalents, short-term investments, cash held in escrow, marketable equity securities, accounts receivable, company-owned life insurance, accounts payable, short-term and long-term debt instruments, and derivatives. The fair values of these financial instruments approximated their carrying values at June 30, 2024 and December 31, 2023, in the aggregate, except for long-term debt instruments. Hedging Activities The Company has exposure to market risk from changes in foreign currency exchange rates and interest rates. As a result, financial instruments, including derivatives, have been used to hedge a portion of these underlying economic exposures. Certain of these instruments may qualify as fair value, cash flow, and net investment hedges upon meeting the requisite criteria, including effectiveness of offsetting hedged or underlying exposures. Changes in the fair value of derivatives that do not qualify for hedge accounting are recognized in Income before income taxes in the period incurred. PPG’s policies do not permit speculative use of derivative financial instruments. PPG enters into derivative financial instruments with high credit quality counterparties and diversifies its positions among such counterparties in order to reduce its exposure to credit losses. The Company did not realize a credit loss on derivatives during the three and six months ended June 30, 2024 and 2023. All of PPG's outstanding derivative instruments are subject to accelerated settlement in the event of PPG’s failure to meet its debt or payment obligations under the terms of the instruments’ contractual provisions. In addition, if the Company would be acquired and its payment obligations under its derivative instruments’ contractual arrangements are not assumed by the acquirer, or if PPG would enter into bankruptcy, receivership or reorganization proceedings, its outstanding derivative instruments would also be subject to accelerated settlement. There were no derivative instruments de-designated or discontinued as hedging instruments during the three and six months ended June 30, 2024 and 2023, and there were no gains or losses deferred in Accumulated other comprehensive loss on the condensed consolidated balance sheet that were reclassified to Income before income taxes in the condensed consolidated statement of income in the six months ended June 30, 2024 and 2023 related to hedges of anticipated transactions that were no longer expected to occur. Fair Value Hedges The Company uses interest rate swaps from time to time to manage its exposure to changing interest rates. When outstanding, the interest rate swaps are typically designated as fair value hedges of certain outstanding debt obligations of the Company and are recorded at fair value. PPG has interest rate swaps which converte d $375 million o f fixed rate debt to variable rate debt as of both June 30, 2024 and December 31, 2023. These swaps are designated as fair value hedges and are carried at fair value. Changes in the fair value of these swaps and changes in the fair value of the related debt are recorded in interest expense in the accompanying condensed consolidated statement of income. The fair value of these interest rate swaps were liabilities of $21 million and $14 million at June 30, 2024 and December 31, 2023, respectively. Cash Flow Hedges At times, PPG designates certain foreign currency forward contracts as cash flow hedges of the Company’s exposure to variability in exchange rates on third party transactions denominated in foreign currencies. There were no outstanding cash flow hedges at June 30, 2024 and December 31, 2023. Net Investment Hedges PPG uses cross currency swaps and foreign currency euro-denominated debt to hedge a significant portion of its net investment in its European operations, as follows: PPG had U.S. dollar to euro cross currency swap contracts with total notional amounts of $475 million as of both June 30, 2024 and December 31, 2023, and designated these contracts as hedges of the Company's net investment in its European operations. During the term of these contracts, PPG will receive payments in U.S. dollars and make payments in euros to the counterparties. As of June 30, 2024 and December 31, 2023, the fair value of the U.S. dollar to euro cross currency swap contracts were net asse ts of $44 million and $33 million, respectively. At June 30, 2024 and December 31, 2023, PPG had designated €3.2 billion and €3.0 billion, respectively, of euro-denominated borrowings as hedges of a portion of its net investment in the Company's European operations. The carrying value of these instruments were $3.4 billion and $3.3 billion as of June 30, 2024 and December 31, 2023, respectively. Other Financial Instruments PPG uses foreign currency forward contracts to manage certain net transaction exposures that either have not been elected, or do not qualify for hedge accounting; therefore, the change in the fair value of these instruments is recorded in Other charges/(income), net in the condensed consolidated statement of income in the period of change. Underlying notional amounts related to these foreign currency forward contracts were $2.6 billion and $2.5 billion at June 30, 2024 and December 31, 2023, respectively. The fair values of these contracts were net liabilities of $1 million as of June 30, 2024 and net assets of $23 million as of December 31, 2023. Gains/Losses Deferred in Accumulated Other Comprehensive Loss The following table summarizes the amount of gains and losses deferred in Other comprehensive income ("OCI") and the amount and location of gains and losses recognized within the condensed consolidated statement of income related to derivative and debt financial instruments for the six months ended June 30, 2024 and 2023.

As of June 30, 2024 and December 31, 2023, the assets and liabilities measured at fair value on a recurring basis were cash equivalents, equity securities and derivatives. In addition, the Company measures its pension plan assets at fair value (see Note 14, "Employee Benefit Plans" under Item 8 in the 2023 Form 10-K for further details). The Company's financial assets and liabilities are measured using inputs from the following three levels: Level 1 inputs are quoted prices in active markets for identical assets and liabilities that the Company has the ability to access at the measurement date. Level 1 inputs are considered to be the most reliable evidence of fair value as they are based on unadjusted quoted market prices from various financial information service providers and securities exchanges. Level 2 inputs are directly or indirectly observable prices that are not quoted on active exchanges, which include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means. The fair values of the derivative instruments reflect the instruments' contractual terms, including the period to maturity, and uses observable market-based inputs, including forward curves. Level 3 inputs are unobservable inputs employed for measuring the fair value of assets or liabilities. The Company did not have any recurring financial assets or liabilities recorded in its condensed consolidated balance sheets as of June 30, 2024 and December 31, 2023 that were measured using Level 3 inputs.

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation The Company’s stock-based compensation includes stock options, restricted stock units (“RSUs”) and grants of contingent shares that are earned based on achieving targeted levels of total shareholder return ("TSR"). All current grants of stock options, RSUs and contingent shares are made under the PPG Industries, Inc. Amended and Restated Omnibus Incentive Plan (“PPG Amended Omnibus Plan”), which was amended and restated effective April 21, 2016. Three Months Ended Six Months Ended ($ in millions) 2024 2023 2024 2023 Stock-based compensation expense $10 $17 $22 $34 Income tax benefit recognized $2 $3 $4 $7 Grants of stock-based compensation during the six months ended June 30, 2024 and 2023 were as follows: Six Months Ended 2024 2023 Shares Fair Value Shares Fair Value Stock options 426,939 $43.83 410,001 $38.55 Restricted stock units 235,633 $135.49 276,897 $125.49 Contingent shares (a) 51,543 $142.65 52,389 $129.03 (a) The number of contingent shares represents the target value of the award. Stock options are generally exercisable 36 months after being granted and have a maximum term of 10 years. Compensation expense for stock options is recorded over the vesting period based on the fair value on the date of grant. The fair value of the stock options granted during the six months ended June 30, 2024 was calculated with the following weighted average assumptions: Weighted average exercise price $142.65 Risk-free interest rate 4.3 % Expected life of option in years 6.5 Expected dividend yield 1.7 % Expected volatility 28.4 % The risk-free interest rate is determined by using the U.S. Treasury yield curve at the date of the grant and using a maturity equal to the expected life of the option. The expected life of options is calculated using the average of the vesting term and the maximum term, as prescribed by accounting guidance on the use of the simplified method for determining the expected term of an employee share option. The expected dividend yield and volatility are based on historical stock prices and dividend amounts over past time periods equal in length to the expected life of the options. Time-based RSUs generally vest over the three-year period following the date of grant, unless forfeited, and will be paid out in the form of stock, cash or a combination of both at the Company’s discretion at the end of the vesting period. Performance-based RSUs vest based on achieving specific annual performance targets for adjusted earnings per share growth and cash flow return on capital over the three calendar year-end periods following the date of grant. Unless forfeited, the performance-based RSUs will be paid out in the form of stock, cash or a combination of both at the Company’s discretion at the end of the three-year performance period if PPG meets the performance targets. The amount paid upon vesting of performance-based RSUs may range from 0% to 200% of the original grant, based upon the level of adjusted earnings per share growth achieved and frequency with which the annual cash flow return on capital performance target is met over the three calendar year periods comprising the vesting period. Performance against the earnings per share growth and the cash flow return on capital target is calculated annually, and the annual payout for each goal is weighted equally over the three-year period. The Company also provides grants of contingent shares to selected key executives that may be earned based on PPG's TSR over the three-year period following the date of grant. Contingent share grants (referred to as “TSR awards”) are made annually and are paid out at the end of each three-year period based on the Company’s stock performance. Performance is measured by determining the percentile rank of the total shareholder return of PPG common stock in relation to the TSR of the S&P 500 Index for the three-year period following the date of grant. This comparison group represents the entire S&P 500 Index as it existed at the beginning of the performance period, excluding any companies that were removed from the index because they ceased to be publicly traded. The payment of awards following the three-year award period is based on performance achieved in accordance with the scale set forth in the plan agreement and may range from 0% to 200% of the initial grant. A payout of 100% is earned if target performance is achieved. Contingent share awards earn dividend equivalents for the award period, which are paid to participants or credited to the participants’ deferred compensation plan accounts with the award payout at the end of the period based on the actual number of contingent shares that are earned. Any payments made at the end of the award period may be in the form of stock, cash or a combination of both. The TSR awards are classified as liability awards, and compensation expense is recognized over the three-year award period based on the fair value of the awards (giving consideration to the Company’s percentile rank of TSR) remeasured in each reporting period until settlement of the awards.

Commitments and Contingent Liab

Commitments and Contingent Liabilities	6 Months Ended
Commitments and Contingent Liabilities	Jun. 30, 2024
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities PPG is involved in a number of lawsuits and claims, both actual and potential, including some that it has asserted against others, in which substantial monetary damages are sought. These lawsuits and claims may relate to contract, patent, environmental, product liability, antitrust, employment and other matters arising out of the conduct of PPG’s current and past business activities. To the extent that these lawsuits and claims involve personal injury, property damage and certain other claims, PPG believes it has adequate insurance; however, certain of PPG’s insurers are contesting coverage with respect to some of these claims, and certain insurers may contest coverage with respect to claims in the future. PPG’s lawsuits and claims against others include claims against insurers and other third parties with respect to actual and contingent losses related to environmental, asbestos and other matters. The results of any current or future litigation and claims are inherently unpredictable. However, management believes that, in the aggregate, the outcome of all lawsuits and claims involving PPG will not have a material effect on PPG’s consolidated financial position or liquidity; however, such outcome may be material to the results of operations of any particular period in which costs, if any, are recognized. Asbestos Matters As of June 30, 2024, the Company was aware of certain asbestos-related claims pending against the Company and certain of its subsidiaries. The Company is defending these asbestos-related claims vigorously. The asbestos-related claims consist of claims against the Company alleging: • exposure to asbestos or asbestos-containing products manufactured, sold or distributed by the Company or its subsidiaries (“Products Claims”); • personal injury caused by asbestos on premises presently or formerly owned, leased or occupied by the Company (“Premises Claims”); and • asbestos-related claims against a subsidiary the Company acquired in 2013 (“Subsidiary Claims”). The Company monitors and reviews the activity associated with its asbestos claims and evaluates, on a periodic basis, its estimated liability for such claims and all underlying assumptions to determine whether any adjustment to the reserves for these claims is required. Additionally, as a supplement to its periodic monitoring and review, the Company conducts discussions with counsel and engages valuation consultants to analyze its claims history and estimate the amount of the Company’s potential liability for asbestos-related claims. As of June 30, 2024 and December 31, 2023, the Company's asbestos-related reserves totaled $46 million and $48 million, respectively. The Company believes that, based on presently available information, the total reserves of $46 million for asbestos-related claims will be sufficient to encompass all of the Company’s current and estimable potential future asbestos liabilities. These reserves, which are included within Other liabilities on the accompanying consolidated balance sheets, involve significant management judgment and represent the Company’s current best estimate of its liability for these claims. The amount reserved for asbestos-related claims by its nature is subject to many uncertainties that may change over time, including (i) the ultimate number of claims filed; (ii) whether closed, dismissed or dormant claims are reinstituted, reinstated or revived; (iii) the amounts required to resolve both currently known and future unknown claims; (iv) the amount of insurance, if any, available to cover such claims; (v) the unpredictable aspects of the tort system, including a changing trial docket and the jurisdictions in which trials are scheduled; (vi) the outcome of any trials, including potential judgments or jury verdicts; (vii) the lack of specific information in many cases concerning exposure for which the Company is allegedly responsible, and the claimants’ alleged diseases resulting from such exposure; and (viii) potential changes in applicable federal and/or state tort liability law. All of these factors may have a material effect upon future asbestos-related liability estimates. While the ultimate outcome of the Company’s asbestos litigation cannot be predicted with certainty, the Company believes that any financial exposure resulting from its asbestos-related claims will not have a material adverse effect on the Company’s consolidated financial position, liquidity or results of operations. Environmental Matters In management’s opinion, the Company operates in an environmentally sound manner and the outcome of the Company’s environmental contingencies will not have a material effect on PPG’s financial position or liquidity; however, any such outcome may be material to the results of operations of any particular period in which costs, if any, are recognized. Management anticipates that the resolution of the Company’s environmental contingencies will occur over an extended period of time. As remediation at certain environmental sites progresses, PPG continues to refine its assumptions underlying the estimates of the expected future costs of its remediation programs. PPG’s ongoing evaluation may result in additional charges against income to adjust the reserves for these sites. In 2024 and 2023, certain charges have been recorded based on updated estimates to increase existing reserves for these sites. Certain other charges related to environmental remediation actions are expensed as incurred. As of June 30, 2024 and December 31, 2023, PPG had reserves for environmental contingencies associated with PPG’s former chromium manufacturing plant in Jersey City, New Jersey (“New Jersey Chrome”), glass and chemical manufacturing sites, and for other environmental contingencies, including current manufacturing locations and National Priority List sites. These reserves are reported as Accounts payable and accrued liabilities and Other liabilities in the accompanying condensed consolidated balance sheet. Environmental Reserves ($ in millions) June 30, 2024 December 31, 2023 New Jersey Chrome $63 $53 Glass and chemical 56 54 Other 117 120 Total environmental reserves $236 $227 Current portion $47 $52 Pretax charges against income for environmental remediation costs are included in Other charges/(income), net in the accompanying condensed consolidated statement of income. The pretax charges and cash outlays related to such environmental remediation for the three and six months ended June 30, 2024 and 2023 were as follows: Three Months Ended Six Months Ended ($ in millions) 2024 2023 2024 2023 Environmental remediation pretax charges $21 $10 $24 $13 Cash outlays for environmental remediation activities $5 $7 $13 $16 In the second quarter 2024, the Company recognized pretax environmental remediation charges of $20 million related to certain legacy PPG manufacturing sites. These legacy environmental remediation charges primarily relate to an increase in the expected cost of groundwater remediation and monitoring at the New Jersey Chrome site and a remedial action design change for the solid waste disposal area at the Ford City, Pennsylvania site. Remediation: New Jersey Chrome In June 2009, PPG entered into a settlement agreement with the New Jersey Department of Environmental Protection (“NJDEP”) and Jersey City, New Jersey (which had asserted claims against PPG for lost tax revenue) which was in the form of a Partial Consent Judgment (the "Consent"). Under the Consent, PPG accepted sole responsibility for the remediation activities at its former chromium manufacturing location in Jersey City and a number of additional surrounding sites. Remediation of the New Jersey Chrome sites requires PPG to remediate soil and groundwater contaminated by hexavalent chromium, as well as perform certain other environmental remediation activities. The most significant assumptions underlying the estimate of remediation costs for all New Jersey Chrome sites relate to the extent and concentration of chromium in the soil. PPG regularly evaluates the assessments of costs incurred to date versus current progress and the potential cost impacts of the most recent information, including the extent of impacted soils and groundwater, and engineering, administrative and other associated costs. Based on these assessments, the reserve is adjusted accordingly. As of June 30, 2024 and December 31, 2023, PPG's reserve for remediation of all New Jersey Chrome sites was $63 million and $53 million, respectively. The major cost components of this liability are related to excavation of impacted soil as well as groundwater remediation. These components each account for approximately 55% and 25% of the amount accrued at June 30, 2024 , respectively. There are multiple, future events yet to occur, including further remedy selection and design, remedy implementation and execution and applicable governmental agency or community organization approvals. Considerable uncertainty exists regarding the timing of these future events for the New Jersey Chrome sites. Further resolution of these events is expected to occur over the next several years. As these events occur and to the extent that the cost estimates of the environmental remediation remedies change, the existing reserve for this environmental remediation matter will continue to be adjusted. Remediation: Glass, Chemicals and Other Sites Among other sites at which PPG is managing environmental liabilities, remedial actions are occurring at a chemical manufacturing site in Barberton, Ohio where PPG has completed a Facility Investigation and Corrective Measure Study under the United States Environmental Protection Agency's Resource Conservation and Recovery Act Corrective Action Program. PPG has also been addressing the impacts from a legacy plate glass manufacturing site in Kokomo, Indiana under the Voluntary Remediation Program of the Indiana Department of Environmental Management and a site associated with a legacy plate glass manufacturing site near Ford City, Pennsylvania under the Pennsylvania Land Recycling Program under the oversight of the Pennsylvania Department of Environmental Protection. PPG is currently performing additional investigation and remedial activities at these locations. With respect to certain other waste sites, the financial condition of other potentially responsible parties also contributes to the uncertainty of estimating PPG’s final costs. Although contributors of waste to sites involving other potentially responsible parties may face governmental agency assertions of joint and several liability, in general, final allocations of costs are made based on the relative contributions of wastes to such sites. PPG is generally not a major contributor to such sites. Remediation: Reasonably Possible Matters In addition to the amounts currently reserved for environmental remediation, the Company may be subject to loss contingencies related to environmental matters estimated to be as much as $100 million to $200 million. Such unreserved losses are reasonably possible but are not currently considered to be probable of occurrence. These reasonably possible unreserved losses relate to environmental matters at a number of sites, none of which are individually significant. The loss contingencies related to these sites include significant unresolved issues such as the nature and extent of contamination at these sites and the methods that may have to be employed to remediate them. The impact of evolving programs, such as natural resource damage claims, industrial site re-use initiatives and domestic and international remediation programs, also adds to the present uncertainties with regard to the ultimate resolution of this unreserved exposure to future loss. The Company’s assessment of the potential impact of these environmental contingencies is subject to considerable uncertainty due to the complex, ongoing and evolving process of investigation and remediation, if necessary, of such environmental contingencies, and the potential for technological and regulatory developments.

Revenue Recognition	Jun. 30, 2024
Revenue Disclosure [Abstract]
Revenue Recognition	Revenue Recognition The Company recognizes revenue when control of the promised goods or services is transferred to the customer and in amounts that the Company expects to collect. The timing of revenue recognition takes into consideration the various shipping terms applicable to the Company’s sales. For most transactions, control passes in accordance with agreed upon delivery terms. The Company delivers products to company-owned stores, home centers and other regional or national consumer retail outlets, paint dealers, concessionaires and independent distributors, company-owned distribution networks, and directly to manufacturing companies and retail customers. Each product delivered to a third-party customer is considered to satisfy a performance obligation. Performance obligations generally occur at a point in time and are satisfied when control of the goods passes to the customer. The Company is entitled to collection of the sales price under normal credit terms in the regions in which it operates. Accounts receivable are recognized when there is an unconditional right to consideration. Payment terms vary from customer to customer, depending on creditworthiness, prior payment history and other considerations. The Company also provides services by applying coatings to customers' manufactured parts and assembled products and by providing technical support to certain customers. Performance obligations are satisfied over time as critical milestones are met and as services are provided. PPG is entitled to payment as the services are rendered. For the three and six months ended June 30, 2024 and 2023, service revenue constituted less than 5% of total revenue. Net sales by segment and region for the three and six months ended June 30, 2024 and 2023 were as follows: Three Months Ended Six Months Ended ($ in millions) 2024 2023 2024 2023 Performance Coatings United States and Canada $1,405 $1,397 $2,526 $2,520 Europe, Middle East and Africa ("EMEA") 981 990 1,865 1,890 Asia Pacific 289 291 530 547 Latin America 373 363 741 712 Total $3,048 $3,041 $5,662 $5,669 Industrial Coatings United States and Canada $634 $662 $1,255 $1,315 EMEA 473 530 948 1,058 Asia Pacific 445 445 860 836 Latin America 194 194 380 374 Total $1,746 $1,831 $3,443 $3,583 Total Net Sales United States and Canada $2,039 $2,059 $3,781 $3,835 EMEA 1,454 1,520 2,813 2,948 Asia Pacific 734 736 1,390 1,383 Latin America 567 557 1,121 1,086 Total PPG $4,794 $4,872 $9,105 $9,252 Allowance for Doubtful Accounts All trade receivables are reported on the condensed consolidated balance sheet at the outstanding principal amount adjusted for any allowance for doubtful accounts and any charge-offs. PPG provides an allowance for doubtful accounts to reduce trade receivables to their estimated net realizable value equal to the amount that is expected to be collected. This allowance is estimated based on historical collection experience, current regional economic and market conditions, the aging of accounts receivable, assessments of current creditworthiness of customers and forward-looking information. The use of forward-looking information is based on certain macroeconomic and microeconomic indicators, including, but not limited to, regional business environment risk, political risk, and commercial and financing risks. PPG reviews its allowance for doubtful accounts on a quarterly basis to ensure the estimate reflects regional risk trends as well as current and future global operating conditions. The following table summarizes the activity for the allowance for doubtful accounts for the six months ended June 30, 2024 and 2023: Trade Receivables Allowance for Doubtful Accounts ($ in millions) 2024 2023 January 1 $25 $31 Bad debt expense 5 6 Write-offs and recoveries of previously reserved trade receivables (4) (7) Other — (2) June 30 $26 $28

Accounting Policies [Abstract]
New Accounting Standards	Recently Adopted Accounting Standards Effective January 1, 2024, PPG adopted Accounting Standards Update ("ASU") No. 2023-02, "Investment - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method." This ASU permits reporting entities to elect to account for tax equity investments under the proportional amortization method, regardless of the tax credit program from which the income tax credits are received, if certain conditions are met. Adoption of this ASU did not have a material impact on PPG's consolidated financial position, results of operations or cash flows. Recently Issued Accounting Standards In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2023-07 “Improvements to Reportable Segment Disclosures (Topic 280)”. This ASU updates current reportable segment disclosure requirements to require disclosures of significant reportable segment expenses that are regularly provided to the Chief Operating Decision Maker (“CODM”) and included within each reported measure of a segment's profit or loss. This ASU also requires disclosure of the title and position of the individual identified as the CODM and an explanation of how the CODM uses the reported measures of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources. This ASU will be effective for the annual period ending December 31, 2024. Adoption of this ASU will result in additional disclosure, but it will not impact PPG’s consolidated financial position, results of operations or cash flows. In December 2023, the FASB issued ASU No. 2023-09 “Improvements to Income Tax Disclosures (Topic 740)”. This ASU updates current income tax disclosure requirements to require disclosures of specific categories of information within the effective tax rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. This ASU will be effective for the annual period ending December 31, 2025. Adoption of this ASU will result in additional disclosure, but it will not impact PPG’s consolidated financial position, results of operations or cash flows.
