On July 29, 2025, at an auto dealership in Indiana, Lee Zeldin, Administrator of the U.S. Environmental Protection Agency (EPA), announced a proposal to withdraw the Endangerment Finding for greenhouse gases (GHGs), which has been EPA’s legal basis for using the Clean Air Act to fight climate change. This action, which will surely be fought in court once it becomes final, raises a host of legal issues. This article discusses the legal basis for and significance of the Endangerment Finding; Zeldin’s principal arguments for revoking it, and challenges that will be raised to them; the range of possible outcomes in the likely event that this reaches the Supreme Court; and the implications of the various outcomes.
