EPA Repeals Carbon Emission Limits for Power Plants

The United States Environmental Protection Agency finalized the repeal of 2024 carbon pollution standards for coal- and gas-fired power plants on September 15, 2026. Announced by Administrator Lee Zeldin during a G20 energy ministers' meeting in Houston, the action eliminates mandates that required plants to adopt carbon-capture technology or use cleaner fuels to reduce emissions. The agency also proposed a separate rule to rescind all remaining greenhouse gas standards for the power sector, arguing that the Clean Air Act does not grant the agency authority to regulate emissions based on climate change.

Administrator Zeldin characterized the move as the largest power sector deregulatory action in U.S. history, claiming it will save the industry $310 billion and lower electricity prices for consumers. The administration argues the rollback is necessary to ensure grid reliability amid rising electricity demand from manufacturing and AI data centers. To support this legal shift, the EPA cited the previous revocation of the 2009 Endangerment Finding, asserting that greenhouse gas emissions from power plants have no material impact on global climate change.

Environmental organizations and Democratic lawmakers condemned the decision, calling it a betrayal of public health and a gift to the fossil fuel industry. Critics warn the repeal will increase pollution-related deaths and accelerate global warming. Democratic-led states and groups including the Sierra Club and the Natural Resources Defense Council have vowed to challenge the rule in court, with some analysts predicting the case will reach the Supreme Court.
