On December 2, 2023, the US Environmental Protection Agency (EPA) released a final report that substantially increases estimates of the social cost of greenhouse gases (GHG), including carbon dioxide, methane, and nitrous oxide (collectively, SC-GHG).

Indeed, federal agencies are expected to use the estimates in future rule-makings and in the environmental review of forthcoming projects.
