However, the fuel-cycle PM 10 , PM 2.5 , SO 2 , and NO x emissions of EVs could be up to five times higher than those of ICEVs (internal combustion engine vehicles) and CNGVs. Although EVs have a greater GHG reduction benefit than CNGVs, they may increase life-cycle emissions of criteria pollutants, simply because coal is heavily involved.
