Summary The alternative fuel vehicles technology has been developed substantially to accommodate the raising environmental awareness and the rising global petroleum price for the purpose of providing the general public a future with less energy consumption and GHG emissions. Thus, to make use of the life-cycle perspective to investigate in detail the energy consumption and GHG emissions of domestic modes is indeed inevitable.

　　The GREET model from the US was utilized in the report of A Life Cycle Analysis of Domestic Private Cars regarding Energy Consumption and Greenhouse Gas Emissions published by IOT in 2011. And, the modified GREET model with some parameter adjustments to meet local situations was used to analyze the energy consumption and GHG emissions of gasoline and diesel vehicles. In this study, the modified GREET model is also used to investigate the characteristics of energy consumption and GHG emissions of the domestic-produced MPV electric vehicles for each stage during the life-cycle.

　　The results indicate that, electric vehicles do not emit CO2 during the operation stage, and its energy consumption is less than that of the gasoline vehicles. In addition, from the life-cycle perspective, the energy consumption and GHG emissions per kilometer of the electric vehicles are still less than those of the gasoline vehicles. Nevertheless, the energy consumption and GHG emissions during the electricity generation/distribution process are relatively high compared with those of the refinement/distribution process of gasoline. This paper also drew up policies based upon the findings with the life-cycle perspective. We hope that the results could also be served as reference for the promotion of electric vehicles in the future with less energy consumption and GHG emissions.
