Abstract This study applied the norm of requirements of the greenhouse gas emission accounting and reporting-ceramic production enterprise and life cycle multi-greenhouse gas method to quantitatively analyze the carbon emissions of ceramic tiles in China. It was found out and analyzed the differences between the two methods in order to improve the carbon emission accounting method for ceramic tiles. In addition, the carbon emission reduction potential of the three energy-saving technologies were calculated from the perspective of the life cycle, which provided methods and data support for the low-carbon development of China’s building ceramics industry. The results showed that carbon emissions of building ceramics was 17.20 kg CO2 eq./m2 based on the life cycle multi-greenhouse gas method, while it was 10.80 kg/m2 based on the norm. The CO2, CH4 and N2O emissions accounted for 98.62%, 1.11% and 0.27% to the total carbon emission. Ceramic tile production, energy production and raw materials acquisition stages accounted for 43.05%, 32.60% and 17.88%, respectively. The dry milling, low-temperature fast-burning and multi-layer drying kiln firing technology contributed to the carbon reduction potential 50.76%,13.98% and 1.44%, respectively.
