A model for estimating air pollutant emissions from cement industry was developed based on emission factors for the greater Beijing-Tianjin-Hebei region. The estimated emissions based on the model were used to analyze of current status and emission characteristics of the major air pollutants, including SO2, NOx, and PM from cement industry in 2016. The results showed that the emissions of SO2, NOx and nonfugitive PM from cement industry were 3.2×104t、23.9×104t、9.7×104t, 24.1%, 18.2%, 27.2% less than which in 2015, respectively. Fugitive PM contributes to 45.4% of the total PM emissions, and it is necessary to enhance colleting the fugitive PM emissions. Shandong and Henan are the greater contributor of SO2, NOx, PM, PM10 and PM2.5 emissions from cement industry. More phasing out of abundant cement producing capacity in these two provinces should be a key measure to reduce their emissions. The cutting-edge technologies such as high efficiency nitrogen and sulfur removal technology, collaborative disposal technology and high efficiency baghouse filter should be considered reduce the emissions from the New Dry Process clinker production, and the pollution control in the grinding stations also need to be strengthened.
