To　make　clear　the　environmental　damages　and　potential　improvements　of　Chinese　cement　industry,　the　detailed　life　cycle　inventory　(LCI)　of　cement　manufacture　with　direct　input　and　output　in　the　boundary　of　cement　plant　as　well　as　corresponded　transport　is　conducted.　The　functional　units　are　1　t　of　Portland　Ordinary　cement　and　1　t　of　clinker.　The　input　data　contain　not　only　the　traditional　items　such　as　raw　materials　(limestone,　sandstone,　ferrous　tailings　and　gypsums),　energy　(coal　and　electricity),　and　admixtures　(fly　ash　and　furnace　slag),　but　also　fresh　water　which　is　not　paid　attention　in　other　literature.　The　output　data　contain　not　only　greenhouse　gas　(CO2)　and　primary　pollution　(NOx,　PM,　SO2),　but　also　the　hazardous　air　pollutants　(HCl,　NMVOC,　PCDD/Fs,　PAHs　and　fluoride)　as　well　as　noise　and　heavy　metal　emissions　(As,　Cd,　Cr,　Hg,　Ni,　Pb,　Zn,　Cu)　which　are　usually　neglected　by　others.　The　data　were　measured　on-site.　The　applications　of　reducing　pollutants　and　waste　heat　recovery　technologies,　and　AFRs　usage　in　cement　industry　are　evaluated.　The　three　steps　of　developments　of　LCI　study　for　China　cement　industry　are　discussed.　(C)　2014　Elsevier　Ltd.　All　rights　reserved.
