In this edition of Wilson Center NOW, we are joined by Barry Rabe, the Arthur Thurnau Professor of Environmental Policy and the J. Ira and Nicki Harris Family Professor at the Gerald R. Ford School of Public Policy at the University of Michigan. He discusses his latest article, “Carbon Pricing Enters Middle Age.” The article “reviews the last half-decade of global climate policy and carbon pricing experience and examines the significant political challenges to pricing adoption in nations including the United States.”
