The Trump administration’s EPA ended the Endangerment Finding, the scientific and legal basis for limits on climate pollution, and gutted tailpipe emissions standards for new cars and trucks.

This move is illegal. So NRDC is preparing to sue the EPA to stop it.

The Trump administration’s Environmental Protection Agency (EPA) repealed the Endangerment Finding — the scientific and legal foundation for tackling climate pollution — and gutted limits on greenhouse gas emissions from newly manufactured vehicles.

This move is illegal. So NRDC is preparing to sue the EPA to stop it.

The Endangerment Finding is grounded in decades of peer‑reviewed science and has been upheld repeatedly by the courts. It is core to limits on greenhouse gas pollution, including standards that require new cars and trucks to cut climate‑warming emissions.

By attempting to erase the Endangerment Finding, the EPA is trying to clear the way for eliminating other pollution protections altogether — handing polluters a free pass while exposing the public to worsening climate change, turbocharged unnatural disasters, and serious health risks.

That’s why NRDC and our partners are preparing to go to court to challenge these actions. But we also need to mobilize a massive, nationwide public outcry to show the EPA that the people are watching — and we will keep fighting until the agency fulfills its responsibilities to us, not polluters.

NRDC is preparing to sue to stop the EPA’s illegal giveaway to polluters. Help us get to 25,000 signatures for climate protections.

Right now, people across the U.S. are suffering the impacts of extreme frigid temperatures, and our nation continues to reel from a year of unprecedented wildfires and hurricanes, record heat waves, and extreme flooding. At this critical moment for our climate, the Environmental Protection Agency (EPA) must not turn its back on our climate reality — or the law.

The Endangerment Finding reflects a commonsense, science-based conclusion: Climate pollution threatens Americans’ health and welfare. Repealing it ignores decades of evidence and asks the public to disregard dangerous climate change driven extreme weather happening just outside our doors.

By repealing the Endangerment Finding and dismantling limits on greenhouse gas pollution from new vehicles, the EPA is handing polluters a free pass while communities face escalating climate disasters.

I won’t stand for this.

I WILL stand with NRDC in defending climate science and the law.
