Abstract: The emission factor method is utilised to establish an emission inventory of CO₂ and air pollutants (PM_2.5, PM₁₀, SO₂, NOx, CO, VOC, NH₃) for the cement industry in the Beijing-Tianjin-Hebei (BTH) region from 2018 to 2020. CO₂ and CO are prominent among the eight atmospheric emissions, up to 55.06 Mt, 45.40 Mt, and 66.87 Mt, and 123.74 kt, 99.42 kt, and 147.02 kt in 2018-2020, respectively. Furthermore, the emissions from Tangshan and Shijiazhuang account for nearly 50% of the total emissions in the region, based on the design capacity of cement enterprises in different cities. Finally, considering emission reduction technologies and the impact of cement production, the potential for CO₂ and major air pollutant emissions reduction in 2030 and 2050 is predicted. According to the scenarios, the emission reduction of CO₂, PM_2.5, SO₂, and NOx will all exceed half in 2030.
