Then the potential of CO reduction of HEV and BEV is simulated under GREET model in this paper, and the factors affecting CO emissions 2 2 of BEV are power structure and power technology route. According to the result, the energy saving effect of BEV is better than HEV because the energy saving rates of HEV and BEV were 24.24% and 37.23% respectively in 2011, and BEV would change the fossil energy consumption structure of the vehicles. The CO reduction effect of HEV is better than BEV, because the CO
