An International Comparison of CO2 Emission Performance and Reduction Potential Using Environmental Production Technology

CO2 emission performance and reduction potential indicators are proposed in this paper by environmental production technology under total-factor framework. Based on this, we give an empirical research on 49 world major emitting countries from 2001 to 2007. The result shows: the average performance of all countries only has very small fluctuation, staying at 0.65 to 0.67; America and Europe’s performance is relatively high and Asia is the lowest but its gap with other countries is shrinking. Now CO2 emission reduction potential has shown an up-trend year by year in these countries, especially for China, India and Japan in Asia.
