Abstract It was still controversial that whether fuel-cycle greenhouse gas (GHG) emissions from battery electric automobile (BEA) are lower than that from gasoline automobile (GA). For analyzing the fuel-cycle GHG emissions reduction from BEA in China, this article accounted fuel-cycle GHG emissions of general BEA and GA based on "China 2007 GHG Emissions EIO-LCA" model. The results showed that the fuel-cycle GHG emissions were 124 gCO2,e/km for BEA and 265 gCO2,e/km for GA. Therefore, compared to GA, BEA could reduce GHG emissions by 53%. Furthermore, the results showed that the main sectors that affect the GHG emissions of BEA included "Production and Supply of Electric Power and Heat Power" and "Mining and Washing of Coal", etc. The GHG emissions of BEA could be reduced by primary energy structural optimization and efficiency improvement of electric networks, etc.
