Under the Clean Air Act, the Environmental Protection Agency (EPA) is required to regulate emissions that “cause, or contribute to, air pollution which may reasonably be anticipated to endanger public health or welfare.” The Supreme Court held in Massachusetts v. EPA that greenhouse gases are considered pollutants under the Act, so whether they can be regulated depends on whether they endanger public health. The EPA issued the Endangerment Finding that greenhouse gas emissions cross this threshold in 2009. Any actual regulation of greenhouse gas emissions is issued by EPA separately, such as greenhouse gas emissions standards for vehicles. On March 12th, 2025, EPA Administrator Lee Zeldin announced that the EPA would be initiating “formal reconsideration of the 2009 Endangerment Finding in collaboration with the Office of Management and Budget (OMB) and other relevant agencies.”

Join us Friday, May 9th, from 11am – 12pm EST, as our panel of legal experts discusses the various questions surrounding the proposed revisions, such as preemption, cost revision, and how these changes would be implemented.
