In a stunning reversal that could redefine global environmental policy, the U.S. Environmental Protection Agency (EPA) announced plans on July 29, 2025, to withdraw the 2009 “Endangerment Finding”—a landmark legal foundation that has empowered federal agencies to regulate greenhouse gas emissions for more than 15 years.
The decision follows months of internal review and a June 2025 Supreme Court decision that narrowed the EPA’s authority over carbon dioxide emissions under the Clean Air Act. If finalized, the rollback could invalidate long-standing rules on vehicle fuel standards, power plant emissions, and future climate legislation in the United States.
Critics warn the move could dismantle America’s entire climate policy infrastructure, while supporters argue it restores constitutional checks on federal overreach.
What Is the Endangerment Finding?
First issued in 2009 under the Obama administration, the Endangerment Finding concluded that six greenhouse gases—most notably carbon dioxide, methane, and nitrous oxide—posed a threat to public health and welfare. That finding legally obligated the EPA to regulate emissions under Section 202 of the Clean Air Act.
The policy served as the backbone for regulations including:
- Vehicle emissions and fuel efficiency standards.
- Mercury and Air Toxics Standards (MATS).
- The Clean Power Plan (later replaced by Trump’s Affordable Clean Energy rule).
- Biden-era proposals to cap methane from oil and gas operations.
Without it, many of these rules could lose their legal basis, potentially collapsing a generation’s worth of climate action.
Why Now?
The rollback comes in the wake of the Supreme Court’s 5–4 ruling in Westmoreland Energy v. EPA (June 2025), which restricted the EPA’s interpretation of “public endangerment” under the Clean Air Act to exclude broad climate-based threats unless explicitly authorized by Congress.
That decision, though technical in nature, effectively challenged the original legal scaffolding supporting the 2009 ruling. Within weeks, EPA Administrator Andrew Wheeler (a Trump-era appointee re-confirmed under the Harris administration as part of a Senate compromise) initiated a formal review process.
On July 29, the EPA confirmed it would issue a Notice of Proposed Withdrawal, triggering a 60-day public consultation period.
Immediate Implications
If finalized, this reversal would:
- Void EPA’s authority to regulate carbon as a pollutant.
- Jeopardize pending legislation tied to emission caps.
- Force the U.S. Congress to pass standalone laws to regulate climate-related emissions.
- Delay or reverse clean energy transition targets, including the federal 2035 Net-Zero Transportation Plan.
- Dismantle the legal basis for numerous ongoing lawsuits against polluters.
International Fallout
The U.S. retreat from climate regulation could have global ripple effects just months before the UN COP30 Climate Summit in Rio de Janeiro. Several EU officials, including Germany’s Climate Minister Franziska Brandner, have condemned the move, warning it threatens to undo recent climate diplomacy gains.
The UK’s Minister for Energy Security and Net Zero, Ed Miliband, issued a pointed statement:
“This is a regressive step by one of the world’s largest emitters. The UK remains committed to strong, science-based climate action rooted in law.”
China, India, and Brazil have yet to formally respond but are reportedly reviewing trade and carbon border tax policies in light of the rollback.
Reactions Within the U.S.
Environmental organisations like the Sierra Club, NRDC, and Earthjustice have vowed legal challenges. White House Climate Advisor Gina McCarthy called the decision “scientifically baseless and morally bankrupt,” adding that the administration is exploring executive alternatives.
Meanwhile, Republican lawmakers and fossil fuel lobbyists have praised the rollback. Senator J.D. Vance (R-OH) tweeted:
“Finally—a win for American energy independence and against climate alarmism.”
What Comes Next?
The EPA is legally required to publish the Notice of Proposed Rulemaking in the Federal Register, initiating a 60-day public comment period. After that, the agency may modify or finalize the rule.
Congressional Democrats are drafting emergency legislation to reinstate the Endangerment Finding, but analysts expect gridlock. If the rollback proceeds, several climate-related court cases could be dismissed or stalled.
The Federal Energy Regulatory Commission (FERC) and the Department of Energy are also reviewing their mandates to determine how deeply the rollback may cut into their operational authority.
The Scientific Community Responds
Top climate scientists across the globe have issued a joint open letter denouncing the rollback. The Intergovernmental Panel on Climate Change (IPCC) called the decision “a political reversal with irreversible planetary consequences.”
Professor Katharine Hayhoe of Texas Tech University warned:
“Removing the Endangerment Finding undermines the foundational scientific consensus that our emissions endanger not just Americans, but the planet. It is not just bad policy—it is scientifically indefensible.”
