Air conditioning system as a key subsystem of environmental regulation within the entire vehicle system， the carbon emission of air conditioning system throughout its entire lifecycle is crucial for meeting the environmental protection and emission requirement of electric vehicle. Combining the life cycle climate performance （LCCP） model of electric vehicle air conditioning system with relevant data， the LCCP values in different provinces of China are analyzed in this paper. Besides， the LCCP values under two different heating schemes and different carbon intensities of electricity are compared. The results show that low-GWP mixed refrigerant RE170/R134a （RE170 to R134a mass fraction ratio 90∶10） can lead to a decrease in LCCP values for electric vehicle air conditioning system by 11.2% to 28.1% in China. Replacing the PTC heater with the heat pump results in a decrease in LCCP values by 0 to 33.1%. In addition， considering the future changes in China's carbon intensity of electricity and the proliferation of electric vehicles， it is anticipated that the LCCP values for an individual vehicle by 2035 will decrease by 31.7% to 39.3%， while the gross electric vehicle LCCP values in China will increase significantly.
