Kelly Brownell and Billy Pizer discuss the pros and cons of different policy approaches to climate change, from carbon taxes to cleaner automobiles and renewable energy. They also discuss the potential for these options to succeed given the polarized political landscape. From 2008 to 2011, Pizer was deputy assistant secretary for environment and energy in the U.S. Department of the Treasury, where he created and led a new office responsible for the department’s role in the domestic and international environment and energy agenda of the U.S. Pizer joined the faculty of the Sanford School of Public Policy at Duke University in the fall of 2011.
