Researchers at the Norwegian University of Science and Technology (NTNU) have compared the emissions resulting from the production, use, and end-of-life of electric and internal combustion engine vehicles (EVs and ICEVs) in a full life-cycle analysis (LCA). This has led to a general perception of EVs as an environmentally benign technology.
