Overview
- EPA Administrator Lee Zeldin’s draft argues the 2009 endangerment finding overstated climate risks and imposed heavy costs on industry by treating U.S. vehicle emissions as a significant threat.
- If finalized, the proposal would strip the Clean Air Act of its authority to regulate greenhouse gases from cars, power plants and other major sources.
- California Governor Gavin Newsom and other state leaders condemned the move as a dismissal of established climate science and a threat to public health.
- The EPA opened a 45-day public comment window on July 29, and environmental organizations have vowed to challenge the revocation in court, with an appeal likely to reach the Supreme Court.
- The rollback follows the administration’s withdrawal from the Paris Agreement and its broader push to prioritize fossil fuel development over climate regulation.
