Climate expert Barrett says incentives, not enforcement, way forward on international policy

As the world's largest emitting countries get ready to meet next week at both the United Nations and the State Department, many questions remain as to how best to approach a post-Kyoto climate strategy. During today's OnPoint, Scott Barrett, professor and director of the International Policy program at Johns Hopkins University and author of the new book, "Why Cooperate? The Incentive to Supply Global Public Goods," explains the role incentives should play in an international climate strategy. Barrett previews next week's international climate discussions and makes recommendations for a post-Kyoto agreement.
