The greenhouse gas (GHG) emissions of passenger cars have mainly been analyzed for vehicle operation phase. However, GHG emissions also occur during fuel and vehicle production. This study analyzed the life cycle GHG emissions of internal combustion engine vehicle (ICEV) gasoline, hybrid electric vehicle (HEV) gasoline, battery electric vehicle (BEV), and fuel cell electric vehicle (FCEV) in South Korea, considering fuel and vehicle production. The results showed that ICEV had the highest fuel cycle GHG emissions, with HEV, BEV, and FCEV emitting 34%, 56%, and 78% less, respectively, compared to ICEV. In terms of vehicle cycle GHG emissions, BEV had the highest emissions, with ICEV, HEV, and FCEV emitting 47%, 37%, and 25% less, respectively. Overall, ICEV, HEV, BEV, and FCEV emitted GHG in that order, with FCEV emitting 66% less than ICEV. These findings highlight the importance of considering both fuel and vehicle cycle GHG emissions to accurately assess total vehicle GHG emissions.
