Comparative study of carbon emission rights allocation schemes:on the equity-efficiency tradeoff
In the long-term stabilization targets of greenhouse gases concentrations,various carbon emission rights allocation schemes have been proposed.To compare and evaluate them,the equity-efficiency tradeoff is the most important.This paper concentrates on this issue through an open policy tool,i.e.the Equitable Access to Sustainable Development model,and considers an emission allowance trade market with limits on import.Under 20 key schemes,the distribution of allowances and associated abatement costs are analyzed.Then the comparison on the equity-efficiency tradeoff side among schemes is further carried out.Both the equity and the efficiency are measured in the global perspective rather than the narrow country level.The equity of first allocation is quantified by the carbon Gini coefficient and the economic efficiency to accomplish obligations is described with the discounted global abatement costs.Our studies indicate that the equity and the efficiency of future emission space allocation approximately show a three-stage relationship.
