Well-to-wheel CO2 analysis of electric and ICE vehicles: are global CO2 emission reductions possible?
In this study, a well-to-wheel CO2 analysis of the usage phase of an Electric Vehicle (EV) compared with Internal Combustion Engine (ICE)-based vehicles is conducted. This study uses vehicle-type approval data of the vehicles and official fuel consumption data for comparison. It was found that EVs move the CO2 emissions from the transport sector to the electricity sector, but contribute to reducing the overall global emissions. For urban driving, this reduction ranges from 30% to 95% depending on the country in question. In rush hour the EV outperforms all other fossil-fuelled alternatives even if charged on electricity from hard coal.
