Based on the environmental statistics data and departmental survey data of Shaanxi Province in 2022, the emission inventory of atmospheric pollutants and CO2 of Shaanxi Province in 2022 was established by a combination method of bottom-up and top-down. The results indicate that the total emissions of SO2, NOx, CO, VOCs, NH3, PM10, PM2.5, BC, OC and CO2 were 64.0×103, 31.2×104, 19.3×105, 21.5×104, 34.0×104, 67.9×104, 20.8×104, 11.7×103, 24.0×103, 33.1×107 tons, respectively. The primary source of SO2 was electricity generation and heating supply; the primary source of NOx and BC was diesel vehicles; the primary source of CO was the iron and steel industry; the primary source of VOCs was the coking industry; the primary source of NH3 was livestock and poultry farming; the primary source of PM10 and PM2.5 was the road dust; and the primary source of OC was biomass stoves. Yulin, Xi'an and Weinan were the major cities with SO2 and PM10 emissions; Yulin, Xi'an and Hancheng were the major cities with PM2.5 emissions; Xi'an, Yulin and Xianyang were the major cities with NOx emissions; Xi'an, Yulin and Yan'an were the major cities with VOCs emissions; Hancheng, Yulin and Xi'an were the major cities with CO emissions; Yulin, Weinan and Baoji were the major cities with NH3 emissions; Yulin, Xi'an and Xianyang were the major cities with BC emissions; Yulin, Xi'an and Weinan were the major cities with OC emissions. On this basis, the pollution and carbon reduction effects of air pollutants and CO2 emission reduction measures were analyzed, and it was found that the cleanification of civil energy, the electricity generation of cleaner power energyin power plants and the renovation of coal-fired boilers all have pollution and carbon reduction effects,while the electricity generation of cleaner power energyin power plants have the highest synergistic effect.
