Efficiency and fairness evaluation of carbon quota allocation methods in the port industry
The historical intensity and benchmark value meth-ods are commonly used for initial allocation of carbon quotas.Currently,only Shanghai and Shenzhen in China have includ-ed the port industry in the carbon trading system,and both use the historical intensity method for initial allocation of quo-tas.This paper proposes five carbon emission quota allocation criteria for the port industry based on the principles of effi-ciency and fairness,namely optimal industry emission reduc-tion efficiency,optimal carbon emission efficiency,encour-agement of advanced players,historical emission responsibili-ty,and large enterprise responsibility.Meanwhile,a efficien-cy-fairness comprehensive evaluation model is constructed for carbon quota allocation in the port industry based on TOPSIS entropy weight method.Empirical analysis is used to evaluate the efficiency and fairness of three quota allocation methods,i.e.,historical intensity method,benchmark value method based on carbon intensity ranking,and mixed allocation meth-od based on energy consumption limit.The results show that under the sub-objectives of efficiency,the sub-objectives of fairness and the comprehensive objective of efficiency-fair-ness,the relative proximity between the evaluation index and the optimal solution of the mixed allocation method based on the energy consumption limit is 0.566,0.711 and 0.638,re-spectively,ranking first among the three allocation methods and obviously higher than the other two methods under the sub-objectives of fairness and the comprehensive evaluation objective.Although the mixed allocation method increases the complexity of the specific implementation process,it indeed improves the efficiency and fairness of the distribution results.
