This bill prohibits federal agencies from using estimates of the "social cost of carbon" and similar greenhouse gas measurements when making regulatory decisions, writing rules, issuing guidance, or conducting cost-benefit analyses. The social cost calculations—which attempt to quantify the economic damages caused by greenhouse gas emissions—have been used by agencies like the EPA since 2009 to justify environmental regulations. Under this legislation, agencies would be banned from considering these monetary damage estimates in any regulatory action or analysis, effectively removing a key analytical tool from the federal rulemaking process. Within 120 days of enactment, all federal agencies must report to Congress detailing how many regulations, guidance documents, and agency actions since 2009 have relied on these social cost measurements. The bill would apply to all federal agencies across the government.
