EPA Social Cost of Greenhouse Gases Application Workbook

This workbook was designed by the National Center for Environmental Economics (NCEE) at the US EPA to help analysts calculate the monetized net social benefits of future reductions in greenhouse gas (GHG) emmissions (or the net social costs of increases in GHG emissions) using the estimates of the social cost of carbon (SC-CO2), social cost of methane (SC=CH4) and Social cost of nitrous oxide (SC-N2)) (collectively referred to as the Social COst of Greenhouse Hasses (SC-GHG) described in USEPA (2023). All files related to the development of these estimates are also included in this deposit. <br />

<blockquote>(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.</blockquote>

<blockquote>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.</blockquote>
