The Environmental Protection Agency announced plans to strip away its authority to regulate greenhouse gas emissions from coal and gas-fired power plants under the Clean Air Act, marking a significant reversal of environmental policy. EPA Administrator Lee Zeldin unveiled the decision at a G20 meeting in Houston on Monday, characterizing the move as protecting American energy independence. The administration projects the change will result in 123 million metric tons of additional carbon emissions over the next decade while saving power plant operators approximately $370 million in compliance costs.
The EPA contended that greenhouse gas emissions from power plants have no meaningful impact on global climate change, a position that contrasts with data showing the US electricity generation sector accounts for roughly one-quarter of the nation’s total greenhouse gas emissions. If considered independently, this sector would rank as the world’s fifth-largest carbon emitter, behind China, the US, India, and Russia. This action follows the administration’s earlier decision to overturn a foundational 2009 EPA determination that greenhouse gases pose a significant public health and environmental threat.
Environmental organizations have pledged immediate legal challenges to the rollback. The Sierra Club’s chief program officer Holly Bender characterized the decision as “full-throated climate denial” and a betrayal of public interest. Former EPA Administrator Gina McCarthy under Barack Obama criticized the decision for allowing major industrial polluters to escape accountability while harming vulnerable populations including children.
The EPA’s reversal eliminates standards that were established under the Biden administration in 2024. Those standards had been projected to reduce greenhouse gas emissions by 1 billion tons by 2047 and prevent approximately 1,200 premature deaths and 360,000 asthma attacks in 2035 alone through improved air quality. The Trump administration modified EPA calculations to no longer include the monetary value of lives saved through reduced air pollution.
This represents the latest chapter in an extended dispute over power sector emissions regulation. A Obama-era clean power plan was struck down by the Supreme Court in 2016, followed by a narrower Biden-era version that operated within court-defined parameters. The current elimination of EPA authority over such emissions would significantly constrain any future regulatory efforts to restrict carbon pollution from power generation facilities.
