The　detailed　life　cycle　assessment　of　heavy-duty　truck　for　highway　transport　in　China　is　conducted　by　Centre　of　National　Material　Life　Cycle　Assessment　(CNMLCA).　The　input　of　energy　and　output　of　pollutants　emissions　are　documented　as　the　life　cycle　inventory　(LCI).　The　life　cycle　impact　assessment　(LCIA)　results　calculated　with　the　CML　method　show　that　the　hotspot　of　environmental　impacts　from　transport　in　China.　The　environmental　benefits　from　implementations　of　European　emissions　standards　in　China　for　transport　are　also　analyzed.　The　analysis　shows　that　the　acidification　potential　(AP)　makes　the　most　huge　contribution　to　total　environmental　impact,　up　to　33.7%.　As　the　second　hotsopt,　global　warming　potential　(GWP)　takes　up　26.83%　of　total　environmental　impact.　Photochemical　oxidant　formation　potential　(POCP)　takes　up　23.42%　of　total　environmental　impact,　which　is　more　or　less　the　same　comparing　with　the　result　of　GWP.　Eutrophication　potential　(EP)　takes　up　15.05%　of　total　environmental　impact.　The　last　but　not　the　least　environmental　impact　category　-　human　toxicity　potential　(HTP),　only　takes　up　0.95%　of　total　environmental　impact.　If　the　heavy　metal　and　dioxin　emissions　are　also　considered,　maybe　the　results　will　be　changed　and　the　HTP　will　take　more　in　the　whole　environmental　impact.　It　can　be　concluded　that　if　we　pay　more　attention　on　SO2　emissions　especially　NOx　emissions　reduction,　the　acidification　and　photochemical　smog　would　be　relieved　a　lot　and　the　total　environmental　impact　can　be　decreased　a　lot.　More　punishment　on　overload　may　be　a　good　choice　to　reduce　environmental　load　of　heavy　truck　of　highway　transport　in　China.　©　(2014)　Trans　Tech　Publications,　Switzerland.
