Fujian　Province　has　entered　the　golden　period　of　industrialization　and　rapid　economic　development,　and　its　economy　and　society　are　undergoing　significant　changes.　An　unreasonable　industrial　structure　and　rapid　growth　of　energy　consumption　will　result　in　a　high　pressure　of　carbon　peak　and　environmental　pollution　in　Fujian　Province　in　2030.　How　to　improve　energy　efficiency,　control　environmental　pollution,　and　achieve　a　carbon　peak　by　2030　while　ensuring　economic　growth　has　become　the　focus　of　the　attention　of　researchers　and　relevant　policymakers.　A　disadvantage　of　the　current　3E　(Economy-Energy-Environment)　system　is　that　it　has　no　quantitative　basis　for　the　selection　of　variables　and　no　combined　analysis　of　carbon　emissions　and　environmental　pollution,　which　is　not　conducive　to　paying　attention　to　environmental　pollution　in　the　process　of　achieving　carbon　peak.　Based　on　the　STIRPAT　(Stochastic　Impacts　by　Regression　on　Population,　Affluence,　and　Technology)　model　analysis　results　of　environmental　pollution　and　carbon　emissions　in　Fujian　Province,　this　paper　established　the　3E　system　model　of　Fujian　Province　to　simulate　three　development　scenarios　and　explored　the　EKC　(Environmental　Kuznets　Curve).　The　results　of　the　STIRPAT　model　showed　that　population,　economic　structure,　and　energy　structure　were　the　main　influencing　factors　of　environmental　pollution　and　carbon　emissions　in　Fujian　Province.　The　3E　system　simulation　results　showed　that　the　current　development　scenario　(scenario　one)　in　Fujian　Province　is　not　sustainable,　and　the　carbon　peak　and　pollutant　reduction　cannot　be　achieved　in　2030.　A　more　stringent　development　scenario　(scenario　three)　was　required　to　achieve　carbon　peak　and　pollutant　reduction　on　schedule.　The　trend　of　the　carbon　emission　EKC　curve　in　Fujian　Province　was　different　from　that　of　environmental　pollution.　The　carbon　emission　EKC　curve　of　Fujian　Province　was　a　common　inverted　＂U＂　shape,　while　the　environmental　pollution　EKC　curve　had　three　shapes　of　＂N＂,　＂M,＂　and　inverted　＂U＂.　This　study　can　provide　a　quantitative　method　for　selecting　3E　system　variables　and　a　new　method　for　establishing　the　3E　model,　and　provide　a　quantitative　reference　for　Fujian　Province　to　develop　subsequent　policies　to　control　carbon　emissions　and　environmental　pollution.
