Join us for a conversation with Professor Emeritus John Dernbach about the USEPA’s proposal to rescind its endangerment finding for greenhouse gases (GHGs).
Pizza will be served!
The EPA is currently inviting public comment on its proposal, which, if adopted, would end EPA’s regulation of GHG emissions from motor vehicles and undermine the legal basis for federal regulation of GHG emissions from all other sources. The conversation will help you to better understand this important issue and to submit comments for the public record.
John C. Dernbach is Professor Emeritus of Environmental Law and Sustainability at Widener University, Commonwealth Law School in Harrisburg, Pennsylvania. Professor Dernbach co-authored an influential amicus brief in the Supreme Court case Massachusetts v EPA that led to EPA issuing its endangerment finding in 2007. He has written and spoken widely on sustainable development, climate change, and environmental law; has significant experience teaching law students and undergraduates; has contributed to three landmark judicial decisions; is the primary drafter of four major Pennsylvania environmental laws; and is the primary author of a legal writing text that is regarded as a classic in the field.
