Transparency and Honesty in Energy Regulations Act

HR 3147, the "Transparency and Honesty in Energy Regulations Act," prohibits federal agencies from using estimates of the climate damage costs from carbon, methane, and nitrous oxide emissions (known as the "social cost" metrics) when creating new rules or guidance. This applies to all agencies, including the EPA, and bans these calculations from cost-benefit analyses required under major executive orders. The bill also requires agencies to report to Congress within 120 days of enactment on how often they previously used these metrics in rulemaking since 2009. The law directly affects how agencies develop environmental regulations by removing specific climate cost estimates from their decision-making process.
