In response to the situation of the unclear air pollutants emission of the steel industry in the Beijing-Tianjin-Hebei Region, and lacking of research on steel industry emission inventory, the  emission inventory research team under Appraisal Center for Environment and Engineering, MEP has developed an emission inventory of iron and steel industry in the Beijing-Tianjin-Hebei Region (BTH-Steel Version 1.0), which is routing-based, bottom-to-up, and high spatiotemporal resolution, based on the data of steel industry surveys, enterprise online emission monitoring and pollution source investigations, considering the concrete information of specific equipment, environmental protection measures, production capacities in the steel industry.

Taking 2012 as the base year, the research of BTH-Steel V1.0 covers Beijing and Tianjin, as well as all 11 cities in Hebei Province (i.e. Shijiazhuang, Tangshan, Handan, Xingtai, Hengshui, Cangzhou, Zhangjiakou, Chengde, Qinhuangdao, Langfang, and Baoding) and deals with main processes in steel industry, including coke oven, sintering, pelletizing, blast furnace, converter, electric furnace, steel rolling. The pollutants cover SO2, NOX, and smoke dust. The research data is mainly derived from steel industry surveys, online monitoring, pollution source investigations (environmental impact assessment and satellite remote sensing), of which online monitoring data comes from key pollution source online monitoring system by Bureau of Environmental Supervision, MEP; environmental impact assessment data is from steel projects approved by MEP over the years; satellite remote sensing data is from remote sensing program of major polluting industries in BTH Region; and large amount of statistical data from steel industry and Hebei provincial government is used in this research for reference.
