Summary
The US Environmental Protection Agency (EPA) announced a proposal on July 29, 2025, to repeal the ‘endangerment finding,’ which officially recognizes greenhouse gases as a threat to human health and welfare. If implemented, this move could eliminate the legal basis for all US greenhouse gas regulations, significantly hindering climate change mitigation efforts. EPA Administrator Zeldin justified the proposal as a response to economic concerns and voter demands, estimating $54 billion in annual cost savings from deregulation. The decision follows a 2024 Supreme Court ruling that limited the EPA’s authority to regulate greenhouse gases. While Zeldin noted that Congress could amend the Clean Air Act to restore regulatory powers, environmental groups criticized the proposal, warning of severe climate consequences. Legal challenges are anticipated from states and advocacy organizations.
