Civil　aviation　transport　is　a　key　area　of　fossil　energy　consumption　and　greenhouse　gas　emission,　and　it　is　also　an　important　source　of　air　pollutants;　the　emissions　of　these　have　caused　severe　environmental　problems.　In　this　paper,　we　estimated　the　emissions　in　235　domestic　civil　airports,　and　predicted　the　future　trends　of　CO2　and　air　pollutant　emissions　from　civil　aviation　in　China　until　2050　under　three　scenarios.　The　co-reduced　emissions　of　each　measure　were　evaluated　by　using　the　co-control　effects　coordinate　system.　The　results　show　that　in　2018,　the　emissions　of　CO2,　NOx,　SO2,　CO,　PM　and　HC　were　117.23　x　10(6)　tons,　90.47　x　10(4)　tons,　14.37　x　10(4)　tons,　9　x　10(4)　tons,　1.29　x　10(4)　tons　and　0.66　x　10(4)　tons,　respectively.　CO2,　NOx,　SO2　and　PM　emissions　were　mainly　concentrated　in　cruise　mode,　accounting　for　87-93%　of　the　total　emissions;　HC　and　CO　emissions　were　more　frequently　from　the　LTO.　Under　the　baseline　scenario,　the　growth　rate　of　air　pollutant　emissions　will　account　for　a　greater　share,　from　84%　in　2030　to　464%　in　2050,　whereas　the　general　scenario　reduces　emissions　by　15%　and　71%,　respectively,　and　a　higher　reduction　of　26%　and　93%　is　seen　in　the　stringent　scenario.　Improving　aviation　fuels　is　the　most　significant　co-reduction　measure,　which　can　reduce　CO2　by　89%　and　68%　in　2030　and　2050,　and　reduce　air　pollutants　by　86-89%　and　62-65%,　respectively.
