Efficiency Analysis of Carbon Emission Quotas

Abstract

This paper analyzes the efficiency of carbon emissions under unexpected output conditions, using the epsilon-based measure of efficiency–data envelopment analysis model with integrated radial and non-radial characteristics, to calculate accurate efficiency values. By assessing China as a case study, taking gross domestic product and population as factors, the study calculates the carbon emission efficiency of all provinces and municipalities simultaneously to achieve fairness in resource allocation. Moreover, the Zero-Sum Gains Data Envelopment Analysis model is applied to optimize carbon emission quotas and establish a reasonable distribution plan. The results provide valuable guidance to policy makers toward formulating suitable energy saving and CO2 emission reduction policies.
