Based　on　the　relevant　data　from　2001　to　2019,　an　internationally　agreed　methodology　for　calculating　CO2　emissions　developed　by　Intergovernmental　Panel　on　Climate　Change　is　used　in　this　paper　to　calculate　CO2　emissions　generated　by　commercial　energy　consumption　in　China.　On　this　basis,　the　regional　heterogeneity　of　commercial　energy　consumption　and　CO2　emissions　is　compared　and　analyzed　on　a　provincial　scale.　Moreover,　the　CO2　emissions　reduction　potential　of　renewable　energy　power　generation　is　analyzed.　The　consumption　of　commercial　energy　and　its　related　carbon　emissions,　the　power　generation　from　renewable　energy　and　its　resulting　carbon　emission　reduction　from　2020　to　2030　are　also　predicted　by　using　SPSS　(Statistical　Product　and　Service　Solutions).　The　prediction　show　that　the　consumption　of　coal,　natural　gas　and　electricity　is　expected　to　be　5592.0699　million　tons,　625.099　billion　cubic　meters,　and　10996.462　billion　kWh,　respectively　by　2030,　when　the　carbon　emissions　reach　the　peak,　and　CO2　emissions　generated　by　the　consumption　of　coal　and　natural　gas　will　reach　9.40　x　10(12)　and　1.37　x　10(12)　kg,　respectively.　Wind,　hydropower,　solar　and　biomass　power　generation　are　expected　to　be　847753.3　kWh,　1933147.57,　498087.78　and　149955.00　GWh,　respectively,　which　can　reduce　CO2　emissions　by　about　2.45　x　10(11),　5.59　x　10(11),　1.44　x　10(11)　and　4.34　x　10(10)　kg,　respectively.
