EPA Moves to Repeal Greenhouse Gas Regulation Basis

The U.S. Environmental Protection Agency, led by Administrator Lee Zeldin under President Trump, has proposed rescinding the 2009 Endangerment Finding, which serves as the scientific and legal foundation for regulating greenhouse gas emissions under the Clean Air Act. The move would eliminate federal authority to regulate emissions from vehicles, power plants, and other sources, marking a significant shift toward fossil fuel expansion and away from renewable energy and climate protections. The administration's justification relies in part on a new Energy Department report that downplays climate risks, a stance widely rejected by climate scientists. The EPA is concurrently delaying or rolling back other climate rules, including methane emission standards, as part of a broader deregulatory agenda. Critics argue the proposal threatens public health and undermines global climate action, while supporters claim it will reduce regulatory costs and boost consumer choice. The proposal is open for public comment and is expected to face legal challenges from states and environmental groups.
