Trump EPA final rule would repeal Biden-era carbon limits on coal and gas power plants

The Trump administration is expected to finalize a rule that repeals Biden-era carbon emission limits for existing coal plants and new gas plants. The EPA says it will announce the decision at a G20 energy meeting in Houston. The rollback also argues the agency has no authority to regulate greenhouse gases from the power sector, a position that could block future administrations from writing similar rules. The Biden standards required up to 90% CO2 reductions and were projected to cut about 1 billion metric tonnes of emissions by 2047. Industry groups support the repeal, citing grid reliability and rising electricity demand from data centers. Environmental and health groups say the change will increase exposure to pollutants and plan to challenge it in court. The rule is part of a broader reversal of US climate policy, including withdrawal from the Paris accord and weaker vehicle emission standards. Legal experts expect the EPA's contradictory legal arguments to be tested in court.
