Peer-reviewed analysis of the economic and technological potential for a comprehensive suite of climate, energy and transportation solutions and policies to greatly reduce U.S. global warming emissions and help get us on a path to avoiding some of the worst impacts of climate change. The results demonstrate that meeting stringent near- and medium-term emissions cap in the United States is feasible and can be done cost-effectively. This analysis is an important contribution to the U.S. and international climate policy debates.
