EPA Administrator Lee Zeldin described the action as the "single largest deregulatory action in U.S. history," claiming costs would drop by over $1.3 trillion.

History

Historical Context

The U.S. Environmental Protection Agency (EPA) issued the Endangerment Finding in 2009, recognizing greenhouse gases as threats to public health under the Clean Air Act. This decision followed the Supreme Court's 2007 ruling in Massachusetts v. EPA, which mandated EPA regulation of greenhouse gases. President Trump's 2026 repeal of this finding, described as a $1.3 trillion deregulatory action, raises concerns about reversing a decade of climate progress.
