EPA Set to Repeal Power Plant Carbon Standards
People familiar with the matter say the U.S. Environmental Protection Agency will formally rescind the carbon-pollution standards that apply to coal- and gas-fired power plants as early as Sept 14, on the sidelines of the G20 energy ministers’ meeting in Houston, Texas. The agency is also preparing a separate rule to eliminate the federal finding that greenhouse gases from power plants pose a threat to public health. The EPA did not respond to requests for comment outside business hours on Sept 13.
Background of Federal Power Plant Regulations
The current standards trace back to rules finalized by the Biden administration in 2024, which required existing and future fossil-fuel plants to adopt emissions-reduction technologies such as carbon capture and storage. Earlier, the Obama administration’s Clean Power Plan mandated similar cuts but was struck down by the Supreme Court in 2022, and a subsequent Trump-era replacement rule was also invalidated by the courts. In 2026 the EPA already rolled back vehicle emissions standards and the 2009 endangerment finding that classified greenhouse gases as a public-health threat.
Quantitative Impact of the Proposed Repeal
The electricity sector accounts for nearly a quarter of U.S. greenhouse-gas emissions. An analysis by the New York University School of Law’s Institute for Policy Integrity estimates that, if treated as a separate country, the U.S. power sector would rank as the world’s sixth-largest emitter. The Biden-era rules were projected to cut carbon dioxide emissions by 1 billion metric tons by 2047; their removal would forgo that reduction.
Official Agency Response
The EPA has not issued a public statement regarding the pending repeal, and its silence on Sept 13 underscores the lack of an official response at this stage.
Potential Implications
Eliminating the standards removes mandates for carbon-capture technology and the endangerment finding that underpins future regulatory actions. If enacted, the repeal could halt progress toward the emissions reductions envisioned in the 2024 rules and maintain the power sector’s status as a major source of national greenhouse-gas output.
