EPA Repeals Biden-Era Power Plant Carbon Rules, Splitting Industry and Environmental Groups

Should the federal government reduce regulations on greenhouse gas emissions from power plants? EPA Administrator Lee Zeldin signed a final rule on September 14, 2026, repealing most of the 2024 Carbon Pollution Standards that limited greenhouse gas emissions from coal and natural gas power plants. The announcement came during a G20 energy ministerial in Houston, where Zeldin said the change would remove $310 billion in compliance costs for the power sector. The EPA also proposed a separate rule, expected to be finalized next year, that would rescind the underlying scientific finding used to justify regulating greenhouse gases from power plants and block future administrations from reinstating similar limits.

The repealed standards, issued under President Biden in 2024, required existing coal plants and new natural gas plants to capture roughly 90 percent of their carbon emissions by the early 2030s using technology such as carbon capture and storage. Zeldin has said an additional $370 billion could be saved if the remaining greenhouse gas standards for the sector are eliminated too. The move is part of nearly three dozen environmental rules Zeldin has targeted since 2025, when he called a related deregulation push the "most consequential day of deregulation in American history."

The power sector currently accounts for roughly a quarter of total U.S. greenhouse gas emissions, according to EPA data. Environmental Defense Fund general counsel Vickie Patton said tearing down the protections would carry costs for public health and safety. Legal groups including the Natural Resources Defense Council have signaled they will challenge the repeal in court, citing the 2007 Massachusetts v. EPA ruling that found the agency has a legal obligation to regulate greenhouse gases under the Clean Air Act.

What supporters say:

  • Zeldin argues the rule exceeded EPA's legal authority and that power plant emissions have no meaningful effect on global climate change, calling the Biden-era standard an attempt to regulate coal "out of existence."

  • Industry groups say the 90 percent capture requirement relied on technology that isn't commercially viable at scale, effectively forcing plants to shut down rather than comply.

  • Trade groups like America's Power say lifting the rule will protect grid reliability at a time of surging electricity demand from data centers and AI infrastructure.

What critics say:

  • Environmental groups say the rollback will worsen air quality and health outcomes, particularly in low-income and majority Black or Hispanic communities that bear a disproportionate pollution burden.

  • Legal advocates argue the repeal conflicts with the Supreme Court's Massachusetts v. EPA precedent, which found the agency is obligated to regulate greenhouse gases once it determines they endanger public health.

  • Critics note the separate proposal to permanently bar future GHG regulation would lock in the policy regardless of who wins future elections, removing the issue from normal regulatory back-and-forth.
