Abstract Based on environmental statistics data, a sophisticated county-based emission inventory on multiple air pollutants from coal-fired industrial boilers (CFIBs) in Beijing-Tianjin-Hebei (BTH) region in 2020 was established by using the emission factor method. Results showed that the emission of SO₂, NO_x, particulate matter (PM), PM₁₀, PM_2.5 from CFIBs in BTH region were about 6351, 7399, 2952, 825, 399t, respectively, of which the emission of PM₁₀ and PM_2.5 accounted for 27.9% and 13.5% of the PM emission. The trace metal emissions of Hg, Pb, Cd, Cr and As were 197.9, 1391.3, 32.0, 1214.2, 362.4kg, respectively. CFIBs with the capacity above 65t/h was the dominant emission sources, and their emission of various pollutants accounted for 51.1% to 81.2% of the total emissions in BTH region, which would be the focus of pollution control and compliance management in the future. Chengde, Tangshan and Zhangjiakou were the top three cities with the largest pollutant emissions with their combined emission accounting for 14.6%~71.9% of the total emissions in the whole BTH region. Some counties within Tianjin, Langfang and Tangshan had relatively high pollutants emission intensities.
