The EPA has proposed rescinding the 2009 endangerment finding. That finding is the scientific and legal basis for regulating greenhouse gas emissions under the Clean Air Act.

It states the obvious that carbon pollution is dangerous and must be controlled. If repealed, every greenhouse gas rule for vehicles would disappear. Automakers would no longer have to measure emissions. They would not be required to build cleaner cars. The largest source of climate pollution in the country would be completely deregulated.

This is not a small change. It is an all-out assault on science, public health, and climate law.

Even while the transportation sector alone accounts for more than a quarter of U.S. emissions, rescinding the endangerment finding as a guiding principle for clean air regulation would have a broad impact across almost every aspect of the EPA’s work, gutting its ability to limit emissions created by any industry or corporation.

That means more pollution, more extreme weather, and higher fuel, energy, and environmental restoration and mitigation costs for everyone, with working families taking the biggest hit.

The EPA is accepting public comments right now. If enough people speak out, we can expose this rollback for what it is, build the public record against it, and help stop the agency from finalizing one of the most destructive climate decisions in its history.
