Substantial part of carbon offset market doesn't mean reduction, Wara and Victor say

PESD scholars Michael Wara and David Victor suggest that a substantial fraction of the $12b market for international carbon offsets does not represent real reductions and that the market is unlikely to provide reliable cost-control for a domestic carbon market. Instead, they suggest that a broader array of strategies will be needed to make a real dent in developing world emissions and that more explicit cost control mechanisms be considered for a U.S. cap-and- trade market for greenhouse gases.
