In this episode I speak with Bob Yuhnke. Bob is a writer and environmental policy analyst who formerly served as co-chair of the transportation subcommittee at the US Climate Action Network. Bob has spent a half century in the fight to protect communities from the diseases of air pollution, and ecosystems from the ravages of acid rain and climate change. He helped lead the fight for clean air as an assistant attorney general responsible for cleaning up steel mill pollution in Pennsylvania, creating the acid rain program as a senior attorney at the Environmental Defense Fund, and contributing to the Clean Air Act Amendments of 1990. Bob earned a degree in American History and political science from Canisius College (’65), and completed all but the dissertation for a Ph.D. in history at the University of Virginia and Columbia University before attending Yale Law School (J.D. ’72).
