Abstract: In this paper, regional per capita CO2 emissions decomposition approach using Theil entropy and Kaya factors decomposition technology is introduced for estimating the interpersonal equality of CO2 emission. The results show that the inequality of per capita CO2 emissions obtained economic equality factor and industrial structure and energy intensity equality factors. Further study showed that there is a big regional difference in carbon emissions interpersonal equality, and it presented a growing trend. Among them, the Eastern economic equality index is relatively large for the development needs of carbon emissions, and Central and Western regions industrial structure and energy intensity equality indexes are relatively small, due to their constraints on carbon reduction capacity. Finally, the paper gives some policy suggestions that China's future carbon emission reduction lies in the development and promotion of symbiotic energy technologies, and the establishment of regional energy technology sharing mechanism and the diffusion mechanism. In addition, the paper indicate that achievements of emissions reduction goals in 2020 and equitable sharing of responsibility, should be considered the various provinces' historical responsibilities and their current development stages and future development needs.
