| Abstract | The displacement of conventional vehicles (gasoline and diesel) by electric vehicles stirs much scientific and public interest. Some studies assessed this displacement but most have focused only on energy and greenhouse gas (GHG) emissions, neglecting other environmental categories. Furthermore, the results of these studies can be contradictory and very dependent on vehicle characteristics (including the battery type), scenarios adopted and the electricity generation system. This paper presents a comparative environmental Life Cycle Assessment (LCA) of conventional and electric passenger cars for Portugal. This study aims at comparing 3 technologies for passenger cars: battery electric vehicle (BEV), gasoline and diesel conventional internal combustion engine vehicles (ICEV), assuming that each vehicle runs for 200 000 km (20 000 km/year). Four scenarios for the Portuguese electricity mix (2004, 2009, 2010, and 2011) were assessed in order to address recent changes. Life cycle impact assessment results for 5 impact categories (climate change (CC), ozone layer depletion (OLD), terrestrial acidification (TA), freshwater eutrophication (FET), marine eutrophication (MET)) are presented for the 3 passenger car technologies. In the years 2010 and 2011, BEV shows lower impacts than ICEVs in the categories: CC, OLD and TA, while for 2004, BEV had lower impacts only for OLD. In 2011 the reduction was: CC (21%), OLD (52%) and TA (7%). Concerning TA impacts, the results also show that the installation (in 2008) of desulfurization and denitrification systems in the Portuguese coal power plants was critical for electric vehicles to present lower impacts than conventional vehicles.
