Accrual for Environmental Loss Contingencies Disclosure [Abstract] |
Environmental Matters | ENVIRONMENTAL MATTERS AND ASSET RETIREMENT OBLIGATIONS Certain Eastman manufacturing facilities generate hazardous and nonhazardous wastes, the treatment, storage, transportation, and disposal of which are regulated by various governmental agencies. In connection with the cleanup of various hazardous waste sites, the Company, along with many other entities, has been designated a potentially responsible party ("PRP") by the U.S. Environmental Protection Agency under the Comprehensive Environmental Response, Compensation and Liability Act, which potentially subjects PRPs to joint and several liability for certain cleanup costs. In addition, the Company will incur costs for environmental remediation and closure and post-closure under the federal Resource Conservation and Recovery Act. Reserves for environmental contingencies have been established in accordance with Eastman's policies described in Note 1, "Significant Accounting Policies", to the consolidated financial statements in Part II, Item 8 of the Company's 2020 Annual Report on Form 10-K. The resolution of uncertainties related to environmental matters may have a material adverse effect on the Company's consolidated results of operations in the period recognized. However, because of the availability of legal defenses, the Company's preliminary assessment of actions that may be required, and the extended period of time that the obligations are expected to be satisfied, management does not believe that the Company's liability for these environmental matters, individually or in the aggregate, will have a material adverse effect on the Company's future liquidity or financial position. The Company's net reserve for environmental contingencies were $286 million and $285 million at June 30, 2021 and December 31, 2020, respectively. Environmental Remediation and Environmental Asset Retirement Obligations The Company's net environmental reserve for environmental contingencies, including remediation costs and asset retirement obligations, is included as part of "Other noncurrent assets", "Payables and other current liabilities", and "Other long-term liabilities" in the Consolidated Statements of Financial Position as follows:
(Dollars in millions) | June 30, 2021 |  | December 31, 2020
Environmental contingencies, current | $ | 15 |  |  | $ | 15 |
Environmental contingencies, long-term | 271 |  |  | 270 |
Total | $ | 286 |  |  | $ | 285 |
Environmental Remediation Estimated future environmental expenditures for undiscounted remediation costs ranged from the best estimate or minimum of $258 million to the maximum of $482 million and from the best estimate or minimum of $257 million to the maximum of $501 million at June 30, 2021 and December 31, 2020, respectively. The best estimate or minimum estimated future environmental expenditures are considered to be probable and reasonably estimable and include the amounts recognized at both June 30, 2021 and December 31, 2020. Reserves for environmental remediation include liabilities expected to be paid within approximately 30 years. The amounts charged to pre-tax earnings for environmental remediation and related charges are included within "Cost of sales" in the Unaudited Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings. Changes in the reserves for environmental remediation liabilities during first six months 2021 and full year 2020 are summarized below:
(Dollars in millions) | Environmental Remediation Liabilities
Balance at December 31, 2019 | $ | 260 |
Changes in estimates recognized in earnings and other | 7 |
Cash reductions | (10) |
Balance at December 31, 2020 | 257 |
Changes in estimates recognized in earnings and other | 7 |
Cash reductions | (6) |
Balance at June 30, 2021 | $ | 258 |
Environmental Asset Retirement Obligations An asset retirement obligation is an obligation for the retirement of a tangible long-lived asset that is incurred upon the acquisition, construction, development, or normal operation of that long-lived asset. Environmental asset retirement obligations consist of primarily closure and post-closure costs. For sites that have environmental asset retirement obligations, the best estimate recognized to date for these environmental asset retirement obligation costs were $28 million at both June 30, 2021 and December 31, 2020. Non-Environmental Asset Retirement Obligations The Company has contractual asset retirement obligations not associated with environmental liabilities. Eastman's non-environmental asset retirement obligations are primarily associated with the future closure of leased manufacturing assets at Pace, Florida and Oulu, Finland. These recognized non-environmental asset retirement obligations were $51 million at both June 30, 2021 and December 31, 2020, and is included as part of "Other long-term liabilities" in the Unaudited Consolidated Statements of Financial Position.
