EPA’s Endangerment Finding Overturned: What It Means | Myron Ebell, Competitive Enterprise Institute

In this episode, Jenny Beth Martin is joined by Myron Ebell of the Competitive Enterprise Institute to discuss the Trump administration’s decision to withdraw the EPA’s 2007 endangerment finding — the legal foundation that has allowed federal regulation of greenhouse gas emissions under the Clean Air Act. The endangerment finding, issued after the Supreme Court’s ruling in Massachusetts v. EPA, opened the door for sweeping climate regulations affecting vehicles, power plants, manufacturing, and energy production across the country. Now, the administration is attempting to reverse that determination — a move that could significantly reshape energy policy, vehicle standards, and federal regulatory authority. In this episode you'll learn: What the EPA’s endangerment finding is and why it matters How greenhouse gases became regulated under the Clean Air Act The connection between federal fuel economy rules and rising vehicle costs The impact of California’s EV mandate and the Clean Air Act waiver What the “major questions doctrine” means for climate regulation Why legal challenges are already underway — and what happens next How this decision could affect energy prices, economic growth, and consumer choice Myron Ebell also shares his decades-long involvement in the climate and energy debate, from opposing the Kyoto Protocol to challenging cap-and-trade proposals and the Paris Climate Agreement. He explains the legal and economic arguments behind the rollback and outlines what to expect as the case moves through the federal courts. This is a deep dive into the legal, economic, and constitutional fight over climate regulation — and what it means for America’s energy future.
