Abstract
The cement industry is a major source of carbon dioxide and air pollutant emissions. This study developed a high-resolution emission inventory for China's cement industry and forecasted emissions from 2025 to 2035. The results showed that emissions in 2020 were 251, 709, 142, and 1.35 × 106 Gg for SO2, NOx, PM2.5, and CO2, respectively. The optimal model projections for 2035 showed that fuel and clinker substitutions had the best reduction effect on SO2 and CO2, with average reduction rates of –11.42 % and –7.37 %, respectively, compared to the 2035 frozen scenario. Pollutant control measures and clinker substitution had the best emission reduction effect on NOx and PM2.5, and the average reduction rates were –26.09 % and –4.23 %, respectively, compared to the 2035 frozen scenario. These results showed that the substitution of fuel and clinker has important co-benefits for air pollutants in the cement industry.
