Synergistic Control of Regional CO2 and Air Pollutant Emissions Reduction in China:A Case Study of Chongqing
摘要
Abstract
In the background of China's dual goals of achieving carbon neutrality and fundamental environmental improvement,Chongqing,as an important strategic pivot point in the development of western China,has the responsibility and obligation to take the lead in reducing pollution and carbon,and help build a national ecological civilization.The emission processes of CO2 and air pollutants are complex and involve many ele-ments,thus it is necessary to clarify the key factors influencing the emission of both,which can provide scientific reference for the realization of synergistic control of pollution reduction and carbon reduction in Chongqing.The extended LMDI-CO2 model and LMDI-AP model based on the log-mean division index(LMDI)model were constructed,and the CO2 emissions and industrial SO2 emissions in Chongqing from 2011 to 2020 were used as objects for empirical analysis.And then the effects of factors on the changes in CO2 and industrial SO2 emissions in Chongqing were evaluated quantitatively.Meanwhile,the influence mechanisms of the factors were unearthed according to the historical development of Chongqing's economy,society,and energy environment,and the key factors of synergistic emission reduction are summarized to explore the syn-ergistic control mechanism of pollution reduction and carbon reduction in Chongqing.The results showed that from 2011 to 2020,the economic development effect was the primary factor driving the increase of CO2 emissions in Chongqing,with a contribution rate of 245.59%.The energy intensity effect contributed the most to CO2 emission reduction,with a contribution rate of-210.51%.In addition,the optimization of industrial structure also contributed to CO2 emission reduction.With the development of the economy,the expansion of population,and the improvement of living standards,the pressure of CO2 and pollutant emission reduction in Chongqing will increase,and the"high carbonization"energy structure will restrict both emission reduction.Improving energy efficiency and optimizing industrial structure played a key role in achieving"double re-duction".Therefore,energy intensity,industrial structure,and energy structure were the three key factors affecting synergistic emission reduction.Reducing energy intensity,upgrading industrial structure,and optimizing energy structure will be important ways to achieve synergistic control of pollution reduction and carbon reduction in Chongqing in the future.关键词
