This bill would prohibit federal agencies from using estimates of the social cost of carbon, methane, nitrous oxide, and other greenhouse gases when making regulatory decisions, conducting cost-benefit analyses, or issuing guidance unless those estimates comply with Office of Management and Budget guidance. The social cost of greenhouse gases is a metric that estimates the economic damages caused by emissions, and it has been used by agencies like the Environmental Protection Agency to justify environmental regulations. The bill affects all federal agencies and would essentially prevent them from factoring climate-related economic harms into their decision-making processes. Within 120 days of the bill becoming law, federal agencies would be required to report to Congress on how many rulemakings, guidance documents, and actions since 2009 have relied on these greenhouse gas cost estimates. The bill contains no specific funding or implementation timeline beyond the reporting requirement.
