Unfortunately those studies do not take into account the pollution and energy needed to create actual battery chemistry, just because that happen in the poorest area of the planet and the fact that actual batteries last from 5 years if used much to 8 if used softly, while ICE cars last more than double and materials in them are partially recycled. As I said: remember the TCO pollution, not just the journey. Oh, BTW CO₂ is a problem, but is not the only nor the worst pollutant, it was just chosen because people can't really embrace nor like complexity and is a thing we can reduce, so something useful for economist games, not for science.
