The Trump administration announced today that it will rescind the 2009 EPA finding that greenhouse gases pose a threat to public health. The declaration was made by President Donald Trump in the White House’s Roosevelt Room.
EPA administrator Lee Zeldin described the move as the largest deregulation effort in U.S. history and said it would save the nation more than one trillion dollars. President Trump added that the repeal would cut regulatory costs by over 1.3 trillion dollars, lower vehicle prices and allow car makers to respond to consumer demand rather than political directives.
Political and legal context
The administration frames the repeal as fulfilment of President Trump’s 2024 campaign pledge for the most aggressive regulatory roll‑back and as his top achievement on climate policy to date.
California Governor Gavin Newsom sent a letter to Zeldin in September stating that California will oppose the repeal and urging the EPA to obey the law, respect established science and fulfil its duty to the public. All Senate Democrats signed a separate letter warning that rescinding the finding would constitute a dereliction of duty and excessive hubris.
Former Department of Justice counsel Michael Buschbacher predicted a prolonged legal battle, saying opponents will fight vigorously but maintaining that the administration is legally correct and that the public welcomes ending costly electric‑vehicle mandates.
Background of the EPA finding
The Clean Air Act, enacted in the 1970s, obliges the EPA to regulate any pollutant that endangers health or welfare. For many years the agency did not interpret the Act to cover greenhouse gases such as carbon dioxide and methane. A coalition of states led by Massachusetts sued the EPA after a 2003 agency determination that the Act did not authorise regulation of greenhouse gases. In 2007 the Supreme Court ruled in favour of the states and instructed the EPA to assess whether greenhouse gases endanger health, leading to the 2009 endangerment finding.
Reactions from environmental groups
Loren Blackford, acting executive director of the Sierra Club, said that removing EPA authority to limit greenhouse gases is both short‑sighted and foolish. The repeal is expected to advantage fossil‑fuel producers and disadvantage renewable‑energy companies.
Legal challenges to the repeal are anticipated to progress through the courts and may reach the Supreme Court. The controversy is projected to become a significant issue in the 2024 presidential election, with Republican supporters praising the repeal as a victory and Democratic officials and environmental groups pledging continued opposition.
