The　rapid　urbanization　has　generated　a　large　amount　of　municipal　solid　waste　(MSW)　in　China.　In　order　to　address　the　universal　issue　of　garbage　siege,　China　continues　to　improve　the　MSW　management　system.　It　has　undergone　different　stages　of　development,　such　as　landfill-based　harmlessness,　incineration-based　harmlessness　and　reduction,　comprehensive　promotion　of　compulsory　classification　of　garbage　in　major　cities,　and　the　comprehensive　treatment　and　disposal　of　classified　garbage.　Taking　Xiamen　City　as　an　example,　the　carbon　emissions　and　characteristics　of　different　MSW　management　stages　were　studied　and　analyzed.　The　results　showed　that　the　total　amount　of　carbon　emissions　in　Xiamen　from　2000　to　2009　(harmlessness　stage)　increased　from　254　900　t　to　763　800　t,　with　an　average　annual　growth　of　13.19%.　From　2010　to　2016　(harmlessness　and　reduction　stage),　the　carbon　emission　intensity　per　ton　of　waste　decreased　each　year　due　to　the　improvement　of　landfill　gas　collection　efficiency　and　the　continuous　promotion　of　waste　incineration　reduction.　However,　the　total　emissions　still　increased　from　279　500　t　to　493　000　t.　Since　2017,　the　city　has　implemented　the　four　classifications　of　garbage,　carried　out　the　classification　of　kitchen　waste,　and　built　a　pilot　project　for　low-value　recyclables.　The　carbon　emission　intensity　has　decreased　from　324.74　kg/t　to　178.11　kg/t,　and　the　carbon　emissions　per　ton　of　food　waste,　recyclables,　kitchen　waste　and　low-value　recyclables　were　reduced　by　5.69,　302.58-328.75,　83.19,　and　884.66　kg,　respectively.　In　the　future,　with　the　promotion　of　low-value　recyclables　classification　and　the　construction　of　renewable　resource　centers,　the　carbon　emission　intensity　and　total　amount　of　domestic　waste　will　be　further　reduced,　promoting　the　city＇s　green　and　low-carbon　development.　©　2024　Editorial　Board　Journal　of　Environmental　Engineering　Technology.　All　rights　reserved.
