Abstract Aiming at the situation of the unclear air pollutants emission of the steel industry in the Beijing-Tianjin-Heibei Region, and lacking of research on steel industry emission inventory, an emission inventory which is routing-based, from bottom to top and high temporal and spatial resolution of steel industry in the Beijing-Tianjin-Hebei Region was developed based on the data of the steel industry research, on-line monitoring and investigation of pollution sources, considering the concrete information of process equipment, environmental protection measures, productivity of the steel industry. In the research, the air pollution emissions of steel industry in the Beijing-Tianjin-Hebei Region in 2012 were calculated: SO2 was 47.16 kt, NOx was 37.22 kt, PM10 was 34.15 kt. Sintering and blast furnace units are the main air pollution emission sources. Air pollution emissions of steel enterprises in Beijing-Tianjin-Hebei region are unbalanced and mainly concentrated in Tangshan, Handan of Heibei province. Emission load and number of steel enterprise of Tangshan and Handan exceeded over 50% of the all region.
