Spatial and temporal correlation of air pollutant and greenhouse gas emission in China

Air pollution control and greenhouse gas emission reduction are key issues in China’s environmental pollution control today, as well as in the whole world. The study on the spatial and temporal relationship between air pollution and climate change in China is important for effective air pollution control. This study analyzed the spatial and temporal variations of PM2.5 concentrations and the spatial and temporal correlations between PM2.5 concentrations and surface temperatures in mainland China and Taiwan and Hainan provinces between 2013 and 2022. Subsequently, the study analyzed the possible causes of PM2.5 changes in different regions and proposed targeted sub-regional countermeasures for the development of synergistic management of air pollution and greenhouse gas abatement.
