Study on the synergistic effect of industrial carbon dioxide and atmospheric pollutant emission control in Yulin City

Under the background of "double carbon" policy, it is of great significance to understand the synergistic effect of industrial carbon dioxide and air pollutant emission to realize pollution reduction and carbon reduction. This study takes the carbon dioxide and air pollutant emissions in Yulin City from 2015 to 2021 as an example. Firstly, the correlation degree of the influencing factors of industrial carbon emissions in Yulin City is calculated by using gray correlation analysis. Secondly, the Kaya constant equation and LMDI model are expanded to analyze the driving effects affecting carbon dioxide and major air pollutant emissions. Finally, a synergistic analysis of the thermal power generation industry and the magnesium smelting industry, which are the key industries in Yulin City, was conducted, and recommendations were made for the reduction of pollution and carbon emissions. The results show that the synergistic emission reduction effect is the first major driving effect driving the reduction of air pollutant emissions. Carbon dioxide emissions have the strongest correlation with nitrogen oxide emissions, and the LMDI model analysis shows that nitrogen oxide and carbon dioxide have significant synergistic effect. The results of this study can provide a scientific basis for the synergistic effect and high-quality prevention of pollution and carbon reduction in Yulin City and provide theoretical support for the government to formulate more practical and feasible strategies for pollution and carbon reduction.
