Abstract：Energy conservation and carbon reduction are significant indicators for environmental performance assessment of green buildings.Vigorously developing green buildings and building high-quality green buildings play important roles in promoting green development in urban and rural construction.This paper summarized and studied the technical indicators of carbon reduction in GB/T 50378-2019"Assessment standard for green building"and GB/T 51141-2015"Assessment standard for green retrofitting of existing building",and analyzed from the aspects of carbon emission reduction forms,carbon source types,quantification methods,and application stages.The operational carbon emissions from new and retrofitted green building certification projects were calculat-ed,and the results showed that the carbon reduction effect of green buildings was significant.Compared with conventional build-ings,green buildings can achieve an average carbon reduction(direct and indirect carbon emissions)of over 40％in the operation stage.If embodied carbon emissions are included,the carbon reduction benefits of green buildings can be more obvious.Further-more,development suggestions are proposed for green building.
