Different　from　the　traditional　bottom-up　approach,　a　combination　of　bottom-up　and　top-down　methods　was　used　to　measure　the　Beijing　high　spatial　resolution　CO2　emission　inventory.　From　the　bottom-up　approach,　based　on　the　data　of　nearly　13000　facilities　(power　station　boilers,　industrial　kilns,　heating　boilers),　the　fossil　energy　consumption　and　carbon　dioxide　emissions　of　fixed　sources　were　calculated.　From　the　top-down　approach,　the　energy　consumption　of　boilers　in　different　industries　were　verified　using　the　energy　consumption　sheet　by　sectors,　thus　the　systematic　errors　of　the　emission　inventory　were　controlled　at　a　macro　level.　It’s　found　that　the　central　urban　area　was　still　the　region　with　the　highest　carbon　density　and　intensity.　To　formulate　a　low-carbon　policy　for　the　next　stage,　Beijing　needs　to　pay　more　attention　to　carbon　emissions　from　road　traffic,　commercial　buildings　and　residents’　lives.　©　2022　Journal　of　Management　and　Business　Research.　All　rights　reserved.
