EPA's “Report on the Social Cost of Greenhouse Gases: Estimates Incorporating Recent Scientific Advances”
(Washington, December 2, 2023) -- In the regulatory impact analysis of EPA’s December 2023 Final Rulemaking, “Standards of Performance for New, Reconstructed, and Modified Sources and Emissions Guidelines for Existing Sources: Oil and Natural Gas Sector Climate Review,” EPA estimated climate benefits using a new set of Social Cost of Greenhouse Gas (SC-GHG) estimates. These estimates incorporate recent research addressing recommendations of the National Academies of Science, Engineering, and Medicine (2017), responses to public comments on an earlier sensitivity analysis using draft SC-GHG estimates included in the December 2022 supplemental proposed rulemaking, and comments from a 2023 external peer review of the accompanying technical report.
The final technical report, “Report on the Social Cost of Greenhouse Gases: Estimates Incorporating Recent Scientific Advances,” explains the methodology underlying the new set of SC-GHG estimates and is included in the docket for the final Oil and Gas rule (HQ-OAR-2021-0317). EPA also conducted an external peer review of the report.
