Wood Mackenzie Research examined the complete energy production chain up to the effective fuel consumption of a vehicle was investigated using a well-to-wheel analysis. The study includes the production, transport and supply of the fuel up to the condition of the consuming vehicle and shows that the exhaust fumes emitted leading to the final journey vary from country to country due to fuel production. Although EVs do not produce emissions at the end of their life, overall they are not emission-free. In certain countries, where the proportion of fossil fuels used to generate electricity is high, an EV can only replace up to half of the greenhouse gas emissions of an ICE gasoline car.
Commenting on the report’s findings, Prakash Sharma, Wood Mackenzie Research Director, said: “The most crucial factor in sustaining the current advantage for EVs is decarbonisation of the power sector. As gasoline ICE vehicles become more fuel efficient, the power mix must comprise more renewables for EVs to remain GHG competitive. Currently, the power sectors in the UK and US are 30% less emissions intensive than markets in Asia.“
