The　Beijing-Tianjin-Hebei　(BTH)　region,　a　highly　industrialized　area　in　China,　boasts　a　concentration　of　coking　plants　that　constitute　a　vital　component　of　the　steel　industry.　In　recent　years,　the　Chinese　government　has　implemented　measures　including　backward　production　capacity　elimination　(BPCE),　ultra-low　emission　technology　transformation　(ULET),　and　deep　treatment　of　volatile　organic　compounds　(DTV),　to　promote　technological　progress　in　the　coking　industry　and　mitigate　the　impact　of　pollutant　emissions.　This　study　focuses　on　the　emission　trends,　reduction　effects　of　various　measures,　and　the　impact　on　air　quality　and　human　health　in　the　regional　scale.　The　findings　reveal　that　in　2015,　the　emissions　of　PM,　SO2,　NOx　and　VOCs　of　the　coking　industry　in　BTH　region　were　29.15,　9.64,　26.62　and　82.99　Gg　(1000　tons/year)　respectively.　However,　by　2019,　these　emissions　had　significantly　decreased　by　19.95,　5.78,　18.69,　and　22.53　Gg,　respectively.　Of　these　reductions,　ULET　contributed　about　80.3　%　of　NOx　and　SO2,　and　57.4　%　of　PM.　Meanwhile,　DTV　and　BPCE　contributed　49.2　%　and　50.7　%　of　VOCs　emission　reduction,　respectively.　Despite　the　improvement　effect　on　PM2.5,　SO2,　and　NO2　is　limited,　the　substantial　decrease　in　VOCs　(particularly　benzene)　resulted　in　a　significant　reduction　in　the　coking　industry＇s　contribution　to　the　atmospheric　benzene　concentration,　dropping　from　15.9　%　in　2015　to　11.6　%　in　2019.　Moreover,　the　lifetime　cancer　risk　(LCR)　contribution　of　benzene　inhalation　in　the　BTH　region　also　decreased　from　1.7　x　10(-6)　to　1.2　x　10(-6).　Looking　ahead　to　2025,　the　continued　implementation　of　DTV　will　be　expected　to　reduce　VOCs　emissions　by　24.41Gg.　This　will　bring　the　industry＇s　contribution　to　the　benzene　concentration　down　to　6.8　%　and　the　cancer　risk　of　the　population　to　an　acceptable　level　(LCR　＜　1　x　10(-6)).　Additionally,　the　deep　treatment　of　VOCs　in　coking　plants　will　significantly　reduce　the　health　risks　faced　by　people　living　in　the　vicinity　of　the　plants.
