To　explore　NOx　mitigation　strategies　in　Chinese　cement　industry　systematically,　a　material　flow　analysis　was　developed.　The　realistic　output　of　cement　production　in　China　were　identified　and　quantified.　The　inventory　data　of　Chinese　cement　production　were　selected　without　denitration　technology　applications　at　that　time.　Then　the　life　cycle　impact　assessment　(LCIA)　results　were　calculated　with　the　principal　of　ISO　14040　and　ISO　14044　of　Life　Cycle　Assessment.　The　impact　categories　of　global　warming　potential　(GWP),　acidification　potential　(AP),　eutrophication　potential　(EP),　photochemical　oxidant　formation　potential　(POCP),　and　human　toxicity　potential　(HTP)　were　used　to　calculate　environmental　impact.　The　results　showed　that　the　NOx　emission　was　the　major　environmental　damages　and　the　following　was　CO2　emission.　This　argument　disagreed　with　the　view　that　CO2　emission　was　the　major　contributor　of　environmental　load.　The　reason　is　that　the　NOx　emission　is　far　over　the　international　level　due　to　few　denitration　technology　applications.　In　the　assumption　of　selective　non-catalytic　reduction　(SNCR)　technology　applications,　there　is　still　large　emission　mitigation　potential　according　to　the　target　scenario　analysis.　The　application　of　selective　catalytic　reduction　(SCR)　technology　with　higher　deNOx　efficiency　and　the　roadmap　of　deNOx　of　Chinese　cement　industry　were　also　discussed.　The　SNCR　technology　with　the　auxiliary　of　SCR　development　over　the　coming　decades　will　be　decisive　for　the　roadmaps　of　Chinese　cement　industry　to　reach　deeper　NOx　emission　cuts.　©　(2015)　Trans　Tech　Publications,　Switzerland.
