According to the problem in environment and emission reduction brought by high energy demand, an evaluation method for terminal control of carbon dioxide emission is proposed.By using interprovincial carbon dioxide calculation method to obtain the terminal carbon dioxide emissions in 30 provinces and by using PCAcluster analysis method, the distribution characteristics of terminal carbon dioxide emissions are analyzed. Cluster analysis analyzes the index variables without knowing the prior knowledge and combines principal component analysis and comprehensive scores for manual discriminant analysis, which can better analyze the distribution characteristics of terminal carbon dioxide. The terminal carbon dioxide pollution degree of each province is generalized and summarized. Research conclusions show that the province with the worst air quality is Hebei Province of North China, followed by entire Central China region and some provinces in East China, South China and North China, and the provinces with the best air quality are in southwest region and in northwest region. The intensification of the pollution treatment in polluted areas is of certain reference significance and reference value to energy structure adjustment and low carbon environment protection.
