Abstract：The energy consumption and pollutants emissions Well-to-Wheels life cycle analysis module affiliated to Tsinghua- CA3EM model was used to calculate the energy consumption and greenhouse gas (GHG) emissions of electric vehicles (EV) for China in 2020. Five coal-power electricity-supplying EV pathways were analyzed with comparison to the mixed grid electricity-supplying EV pathway and conventional gasoline car pathway. Not only the vehicle operating stage was taken into account, but also the stages from resource exploitation, resource transportation to electricity transmission and distribution were analyzed comprehensively. The results show that life cycle energy consumption and GHG emissions of EV are 1 123 ～ 1 592 kJ/km and 131 ～ 162 g Carbon Dioxide equilibrium per-km;EV has the obvious advantages of over 35% of energy-saving and about 20% of GHG emission-reduction compared to gasoline cars; the promotion of EV is in line with China's energy security strategy of substitute coal for oil due to 300% ～ 500% more coal consumption but 97% less petroleum consumption ;there are 80% of GHG emission reduction for the pathway of EV driven by electricity supplied by the combination of advanced coal integrated gasification combined cycle with Carbon Dioxide capture and storage technologies companied with 40% of energy-saving compared to gasoline cars.
