摘要
Decarbonizing the passenger car transportation sector is mandatory. Nevertheless, other envi-ronmental impact categories should also be tackled. This research compares the life cycle envi-ronmental performance of passenger car transportation in Ecuador with energy carriers: first -generation ethanol-gasoline blends and electricity. The battery electric vehicle (BEV) current scenario utilizes the electricity from the 2018 national mix composed of 17% of fossil and 83% of renewable sources. Regarding the flex-fuel vehicle, the current scenario refers to the current mixture percentage of ethanol-gasoline (E5). The functional unit is defined as 1 km. The global warming potential (GWP) results are between 130-180 g CO2-eq/km for E5 and 42-176 g CO2-eq/ km for BEVs. For future scenarios, the GWP ranges are 250-270 g CO2-eq/km for E15 scenarios and 80-130 g CO2-eq/km for E85 scenarios. E85 scenario has less GWP than BEVs scenarios when fossil fuel electricity is used to charge them.
