A Conversation About the Endangerment Finding Rescission
In this episode of Andrew Revkin's "Sustain What" podcast, host Andrew Revkin discusses the EPA's controversial final rule rescinding the greenhouse‑gas endangerment finding, which underpins Clean Air Act regulation of emissions. He is joined by environmental attorney Sean Donohue, a lead challenger of the rule, and journalist Jean Chemnick of E&E News/Politico, who unpack the legal hurdles the D.C. Circuit and potentially the Supreme Court will face. The conversation highlights the statutory limits of EPA authority, the procedural challenges of overturning a longstanding finding, and the broader implications for climate policy and vehicle emissions standards. Donohue provides insider perspective on the pending litigation while Chemnick contextualizes the political and media dimensions of the fight.
