Large electric vehicles responsible for as much
greenhouse gas as some conventional cars
At least for now, some electric vehicles (EVs) may generate about as much greenhouse gas (GHG) as some internal combustion engine vehicles (ICEVs) when judged over their entire cradle-to-grave life. So say researchers from Norway’s Industrial Ecology Programme and Dept. of Energy and Process Engineering, and the Norwegian University of Science and Technology. Writing in […]
