As　the　data　intensive　method,　high　quality　environmental　burden　data　is　an　important　premise　of　carrying　out　materials　life　cycle　assessment　(MLCA),　and　the　reliability　of　data　directly　influences　the　reliability　of　the　assessment　results　and　its　application　performance.　Therefore,　building　Chinese　MLCA　database　is　the　basic　data　needs　and　technical　supports　for　carrying　out　and　improving　LCA　practice.　Firstly,　some　new　progress　on　database　which　related　to　materials　life　cycle　assessment　research　and　development　are　introduced.　Secondly,　according　to　requirement　of　ISO　14040　series　standards,　the　database　framework　and　main　datasets　of　the　materials　life　cycle　assessment　are　studied.　Thirdly,　MLCA　data　platform　based　on　big　data　is　developed.　Finally,　the　future　research　works　were　proposed　and　discussed.
