Abstract:Scientific identification and analysis of the impact of industry factors on carbon emission will be an important basis for formulating targeted emission reduction measures to achieve carbon peak in 2030. Taking the airport aircraft carbon emission of 31 provinces (including autonomous regions and municipalities) from 2007 to 2016 in China as a sample, the study firstly analyzed the temporal and spatial evolution characteristics of China's airport aircraft carbon emission. Then, it used the LMDI decomposition method to discuss the degree of airport openness and airport connectivity strength, transportation intensity and energy consumption intensity on aircraft carbon emissions. Finally, it put forward emission reduction suggestions for improving route planning, optimizing network structure and fleet assignment in response to the impact. The results show that the average annual growth rate of aircraft carbon emission in airports across the country is about 9.46%. The carbon emission level of airport aircraft in the eastern and southwestern regions are relatively high, with Guangdong having the largest added value, Tibet the smallest value, Hebei the fastest growth rate, and Shanghai the slowest growth rate. The changes in the degree of airport openness, airport connection strength, and transportation intensity promote the growth of carbon emission. Among them, the degree of airport openness has the most significant impact on carbon
