The future of climate regulation in the United States hangs in the balance as the Trump administration prepares to dismantle a cornerstone of environmental protection. Amidst record-breaking global temperatures and escalating climate-related disasters, a pivotal decision is expected this week: the formal revocation of the Environmental Protection Agency’s (EPA) 17-year-old finding that greenhouse gas emissions endanger public health and welfare.
This action, if finalized, would effectively strip the EPA of its primary legal authority to regulate greenhouse gases under the Clean Air Act. The move comes as scientists increasingly warn of approaching climate tipping points and communities grapple with the financial strain of extreme weather events, including devastating wildfires. The backdrop is further complicated by the confirmation that 2025 was among the warmest years ever recorded, continuing a disturbing trend.
The Endangerment Finding: A Legal Foundation Under Threat
The “endangerment finding,” initially established in 2009 under the Obama administration, was a landmark decision. It provided the legal justification for the EPA to implement regulations aimed at reducing greenhouse gas emissions from vehicles and power plants. Without this finding, the agency’s ability to address climate change through the Clean Air Act is severely curtailed. Critics argue that removing this safeguard prioritizes short-term economic gains over long-term environmental and public health concerns.
EPA Administrator Lee Zeldin is scheduled to appear alongside President Trump at an event Wednesday dedicated to promoting increased domestic coal consumption, coinciding with the rollback of mercury and air toxics standards. This event is widely anticipated as the prelude to the official announcement of the endangerment finding’s repeal, a directive issued by the President through an executive order on his first day in office for his second term.
What Does This Mean for Climate Action?
The revocation of the endangerment finding doesn’t automatically eliminate all climate regulations, but it significantly weakens the federal government’s ability to enforce them. States and cities may face increased challenges in pursuing their own climate goals, as federal support and legal backing diminish. The move is expected to embolden industries reliant on fossil fuels and potentially lead to increased emissions.
This decision also raises questions about the United States’ commitment to international climate agreements. While the US has rejoined the Paris Agreement, this action signals a potential shift away from ambitious climate targets. What impact will this have on global efforts to mitigate climate change, and will other nations be compelled to accelerate their own reductions to compensate?
The implications extend beyond environmental concerns. Increased air pollution from coal-fired power plants can exacerbate respiratory illnesses and other health problems, disproportionately affecting vulnerable communities. How will the administration address the potential public health consequences of increased reliance on coal?
A History of Regulatory Battles
The fight over greenhouse gas regulation has been a long and contentious one. Prior to the 2009 endangerment finding, legal challenges questioned whether the EPA even had the authority to regulate greenhouse gases as pollutants. The Supreme Court’s 2007 ruling in Massachusetts v. EPA affirmed the agency’s authority, paving the way for the endangerment finding. This latest move represents a reversal of that progress, potentially opening the door to further legal battles.
The Clean Air Act, originally passed in 1970, has been instrumental in improving air quality across the United States. However, its application to greenhouse gases has always been a point of contention. Opponents of regulation argue that the Act was not intended to address climate change and that doing so would impose undue economic burdens. Proponents maintain that the Act’s broad language allows for the regulation of any pollutant that endangers public health and welfare, which they argue includes greenhouse gases.
Beyond the legal framework, the debate over climate regulation is deeply intertwined with economic and political considerations. The fossil fuel industry has long lobbied against regulations that would limit emissions, while environmental groups and public health advocates have pushed for stronger action. The current administration’s decision reflects a clear alignment with the interests of the fossil fuel industry.

Frequently Asked Questions About the EPA’s Endangerment Finding
A: The endangerment finding is a formal determination by the EPA that greenhouse gas emissions pose a threat to public health and welfare. It’s the legal basis for regulating those emissions under the Clean Air Act.
A: Revoking the finding significantly weakens the EPA’s authority to regulate greenhouse gases, potentially leading to increased emissions and hindering efforts to combat climate change.
A: Increased emissions can worsen air quality, leading to respiratory problems, cardiovascular disease, and other health issues, particularly for vulnerable populations.
A: Yes, states and cities can continue to pursue their own climate goals, but they may face legal challenges and lack the federal support previously available.
A: The Clean Air Act is a federal law designed to protect air quality. The EPA used its authority under this act, specifically the endangerment finding, to regulate greenhouse gases.
A: This decision raises concerns about the United States’ commitment to the Paris Agreement and its ability to meet its emission reduction targets.
This decision marks a significant turning point in the nation’s approach to climate change. The long-term consequences remain to be seen, but the immediate impact is a weakening of federal protections and a potential setback for global climate action. What role will public pressure and grassroots movements play in challenging this decision and advocating for a sustainable future?
