Maryland Dept. of Environment's Kinsey, Georgetown's Arroyo talk sustainability action

As countries gear up for next month's Rio+20 sustainability meeting, what role will states and regions play in the discussions? During today's OnPoint, Kathy Kinsey, deputy secretary of regulatory programs and operations at the Maryland Department of the Environment, and Vicki Arroyo, executive director of the Georgetown Climate Center and a visiting professor at Georgetown Law, discuss the effectiveness of subnational programs for climate and sustainability. They also weigh in on how U.S. EPA's action on air regulations affects states' willingness to move forward with their own climate policies.
