Harvard's Cooper says U.S. is on wrong track in policy talks

As the Senate weighs its climate and energy policy options, a new study out of Harvard University evaluates the European Emission Trading System to better understand how a cap-and-trade system would work in the United States. During today's OnPoint, Richard Cooper, a professor of international economics at Harvard University and author of the study, explains which elements of the ETS he believes should be dropped from Senate proposals. He also discusses the successes of the European ETS.
