摘      要：Increasing energy consumption in the transportation sector results in challenging greenhouse gas(GHG)emissions and environmental *** paper involved integrated assessments on GHG emissions and emergy of the life cycle for the internal combustion engine(ICE)and electric automobiles in the USA over the entire assumed fifteen-year *** hotspots of GHG emissions as well as emergy indices for the major processes of automobile life cycle within the defined system boundaries have been *** potential strategies for reducing GHG emissions and emergy in the life cycle of both ICE and electric automobiles were further *** on the current results,the total GHG emissions from the life cycle of ICE automobiles are 4.48 E+07 kg CO2-e which is320 times higher than that of the electric *** hotspot area of the GHG emissions from ICE and electric automobiles are operation phase and manufacturing process,*** results were observed that comparable total emergy of the ICE automobiles and electric automobiles have been calculated which were 1.54 E+17 and 2.20 E+17 sej,*** on emergy index evidenced a better environmental sustainability of electric automobiles than ICE automobiles over the life cycle due to its higher *** the authors’knowledge,it is the first time to integrate the analysis of GHG emissions together with emergy in industrial area of automobile *** is expected that the integration of emergy and GHG emissions analysis may provide a comprehensive perspective on eco-industrial sustainability of automobile engineering.
