In　the　context　of　China’s　dual　carbon　target,　Beijing,　as　the　capital　of　China,　should　play　an　exemplary　role　in　carbon　emission　reduction.　On　the　premise　of　optimizing　high-emission　sectors　such　as　coal　and　industry,　Beijing　is　still　a　certain　distance　from　the　goal　of　carbon　neutrality.　Therefore,　on　the　basis　of　Beijing’s　energy　resource　endowment,　considering　Beijing’s　economic　development　and　carbon　neutrality　goals　and　scientifically　and　reasonably　planning　Beijing’s　carbon　emission　reduction　path　are　important　tasks.　We　construct　an　energy　structure　optimization　model　to　achieve　the　goal　of　carbon　neutrality　by　2050.　The　model　analysis　concludes　that　the　residents　and　transportation　sectors　will　account　for　a　large　proportion　of　Beijing’s　total　carbon　emissions　in　the　future.　To　achieve　the　goal　of　carbon　neutrality,　the　electricity　substitution　of　fossil　energy　and　the　high　proportion　of　external　power　are　two　necessary　measures,　and　the　optimal　path　of　carbon　emission　reduction　is　proposed.　©　2022　by　the　authors.
