Abstract:

In order to explore the influential factors of CO₂ emission and the relationship between various factors, the statistics of total CO₂ emission and the influential factors of CO₂ in the recent years are collected. Meanwhile, the influential factors of CO₂ emission are classified into direct factors and indirect ones. By using Coefficient of Variation Method, Grey theory and Analytic Hierarchy Process (GAHP), the importance and relevance between the CO₂ emission and its various influential factors are analyzed. The results show that the total consumption of natural gas and other energy presents the main direct influential factors for the CO₂ growth, and total fixed asset investment of the whole society and the industry’s GDP are the main indirect influential factors. At the same time, the relationships between CO₂ emission and coal energy and the three major traditional industries in China are closest.
