Overview
- The EPA finalized a partial repeal of the Biden-era 2024 Carbon Pollution Standards on September 14, removing most limits on greenhouse-gas emissions from coal and gas power plants.
- The agency says the change will deliver large regulatory savings and preserve energy options, citing about $310 billion in estimated savings and proposing to remove remaining greenhouse-gas requirements for plants.
- Public-health and environmental groups filed a petition in the U.S. Court of Appeals for the D.C. Circuit on September 17 to block the repeal, arguing the agency violated the Clean Air Act by discarding the standards without replacement.
- Opponents warn the rollback will raise emissions and local air pollution, cost billions in health harms, and cause thousands of premature deaths; the 2024 rule had been projected to cut roughly 1.38 billion metric tons of CO2 through 2047 and to prevent thousands of health impacts such as asthma attacks and deaths.
- The legal fight will hinge on the scope of EPA authority after the Supreme Court's 2022 West Virginia v. EPA decision and the agency's 2025 revocation of the 2009 endangerment finding, and the D.C. Circuit review could determine whether the repeal stands or proceeds to higher courts.
