THANK YOU FOR TAKING ACTION. READY TO TAKE THE NEXT STEP?

BACKGROUND

In a 2007 landmark Supreme Court (SCOTUS) decision, SCOTUS found that EPA is required to act on greenhouse gas emissions (GHGs) under the Clean Air Act. Two years later, EPA issued it’s “endangerment finding,” stating that GHGs, such as carbon dioxide and methane, are a threat to public health and welfare, and consequently began regulating these emissions.

The result—a flurry of critical federal regulations curbing planet warming emissions from sources like dirty fossil fuel-fired power plants to vehicle emissions choking our communities. These regulations save lives, reduce costs for families, and yield hundreds of billions in societal benefits.

In July 2025, the Trump Administration proposed repealing this landmark finding, thus attempting to undermine the scientific and legal basis for climate action in the US. The agency included several arguments for repeal, including lack of authority to set GHG emission standards and that emission standards harm public health and welfare by increasing prices and decreasing consumer choices. This argument is as baffling as it is wrong.

By repealing the endangerment finding, EPA is also looking to roll back the recent vehicle emissions standards that were finalized in 2024 and expected to reduce fuel costs by $62 billion annually amongst many other benefits.

EPA has one job and the Trump Administration wants them to stop doing it. Abandoning the endangerment finding is abandoning the country to a future of climate chaos.  

OUR OPPORTUNITY

Before finalizing this repeal, EPA is taking public comments supporting or opposing the proposal until September 22. EPA is then required to consider and address each relevant and well-supported point in its final rule. If EPA fails to adequately do so, lawyers may argue the agency has not followed requirements and a judge may prevent it from implementing the rule.

To protect federal climate protections, our goal is to flood EPA with as many thoughtful and unique comments opposing the proposal as possible, ensuring the agency must spend the time necessary to consider all angles and address every point in its final rule.
