Electric light-duty vehicles have decarbonization potential but may not reduce other environmental problems

Electric vehicles (EVs) are promoted for their decarbonization potential, but their overall environmental impact depends on the electricity grid mix. This study conducts a comparative life cycle assessment of four light-duty vehicle categories (ICEVs, HEVs, PHEVs, and BEVs) globally and in Norway, the US, and China. Results show that while EVs offer considerable decarbonization potential with cleaner grids, they may not mitigate other impacts like increased respiratory effects in rural, low-income communities. The findings emphasize the need for tailored approaches to sustainable transportation.
