Background Air pollution in China has raised great concerns due to its adverse effects on air quality, human health, and climate. Emissions of air pollutants (APs) are inherently linked with CO_2 emissions through fossil-energy consumption. Knowledge of the characteristics of APs and CO_2 emissions and their relationships is fundamentally important in the pursuit of co-benefits in addressing air quality and climate issues in China. However, the linkages and interactions between APs and CO_2 in China are not well understood. Results Here, we conducted an ensemble study of six bottom-up inventories to identify the underlying drivers of APs and CO_2 emissions growth and to explore their linkages in China. The results showed that, during 1980–2015, the power and industry sectors contributed 61–79% to China’s overall emissions of CO_2, NO_x, and SO_2. In addition, the residential and industrial sectors were large emitters (77–85%) of PM_10, PM_2.5, CO, BC, and OC. The emissions of CH_4, N_2O and NH_3 were dominated by the agriculture sector (46–82%) during 1980–2015, while the share of CH_4 emissions in the energy sector increased since 2010. During 1980–2015, APs and greenhouse gases (GHGs) emissions from residential sources generally decreased over time, while the transportation sector increased its impact on recent emissions, particularly for NO_x and NMVOC. Since implementation of stringent pollution control measures and accompanying technological improvements in 2013, China h...
