A framework to estimate air pollutant emissions from coal-fired power plants, coal-fired boilers, and rural residential coal-using was developed for the "2+26" cities located in the air pollution transport channels in the Beijing-Tianjin-Hebei area. The existing policies and measures to control emissions from burning coal in "2+26" cities were summarized and the potentials of reducing SO₂、NO_x、PM、PM₁₀、PM_2.5 emissions was quantified for year 2017. The results showed that SO₂、NO_x、PM、PM₁₀、PM_2.5 emissions from burning coal were 87×10⁴t、56×10⁴t、64×10⁴t、45×10⁴t、32×10⁴t in 2017, respectively, 44%, 48%, 33%, 32% and 30% less than which in 2015 due to implementation of major emission control measures including the ultra-low emissions retrofitting in coal-fired power plants, eliminating the coal-fired boilers and switching raw coal into electricity (gas). The reduction rates of coal-fired power plants, coal-fired boilers, and rural raw coal were 55%~70%, 31%~38%, 18%~21%, respectively. SO₂ and NO_x emission reductions were mainly attributed to the ultra-low emission of coal-fired power plants for most cities, and PM emission reductions from burning coal of Langfang and Baoding were most significant in the "2+26" cities, mainly thanks to strongly promoting switch from coal into electricity and gas in residential sector.
