The　construction　industry　plays　a　crucial　role　in　China＇s　fulfillment　of　the　goal　of　achieving　＂carbon　neutrality＂　in　2060.　Based　on　the　data　of　energy　and　building　materials　consumption　of　the　construction　industry　in　China　and　30　provinces　from　2008　to　2018,　this　paper　constructs　a　model　for　measuring　provincial　CO2　emissions　of　China＇s　construction　industry　and　establishes　a　Kuznets　curve　and　elastic　decoupling　model　of　the　industry＇s　CO2　emissions.　The　analysis　based　on　the　models　shows　that:　(1)　the　CO2　emissions　of　China＇s　construction　industry　show　a　trend　of　increasing　first　and　then　decreasing;　(2)　in　terms　of　the　decoupling　effects,　most　provinces　are　in　a　weak　decoupling　status　of　CO2　emissions;　and　(3)　the　Kuznets　curve　of　the　provincial　construction　industry　shows　an　inverted　＂U＂　shape　in　recent　years,　and　it　is　predicted　that　the　CO2　emissions　of　the　construction　industry　will　reach　the　peak　in　2034.　It　is　possible　for　the　construction　industry　to　achieve　＂carbon　neutrality＂,　but　long-term　efforts　must　be　made　for　strategic　planning,　policies　and　regulations,　industry　standards,　etc.
