The Best Thing You Can Do Right Now

Tell Congress: Hold Trump’s EPA Accountable

Trump and EPA Administrator Zeldin have repealed the Endangerment Finding, which underpinned critical protections for our health and the environment. This repeal is a blatant denial of climate science and mounting destructive climate disasters. It gives Trump's fossil fuel donors a free pass to pollute the air we breathe with greenhouse gases — so they'll get richer while we get sicker.

Tell Congress: Protect People, Not Polluters
