China announced the goal of carbon peaking by 2035 and carbon neutral by 2060. In 2020, the carbon emission of cement production was 1.32 billion tons, accounting for about 80% of the total carbon emission of building materials in China. The carbon emission of cement production mainly comes from the clinker production. The key to cut emission is to reduce the consumption of fossil energy and limestone. The major measures include energy efficiency improvement, alternative fuel usage, raw material substitution, and new low-carbon cement clinker production technology. This paper illustrates the effect of low carbon technologies application and the carbon reducing potential from this period to 2060. It is predicted that when carbon neutral goal would be achieved by 2060, the carbon reduction from energy efficiency improvement, alternative fuels usage, alternative raw materials usage, low-carbon cement and CCUS technology would be 8%, 4%, 27%, 28% and 33%, respectively. Meanwhile, the 13% of CO 2  related with cement producing would be used to curing cement-based materials.
