EPA Administrator Lee Zeldin announced Monday that the agency is repealing greenhouse gas limits for fossil fuel power plants. The move removes Biden-era rules that required existing coal plants and new natural gas plants to cut CO2 emissions starting in the 2030s. The agency called it the largest deregulatory action for the U.S. power sector in history. Without federal CO2 limits, utilities face less pressure to retire coal early or install carbon capture on gas units. That could slow the near-term shift in generation mix, though state clean energy standards and economics still drive many plant closures. For carbon markets, the repeal changes the regulatory baseline, which may affect how emissions reductions are measured and credited.
