We are transitioning towards it, but in the meantime, switching to EVs still reduces CO2 output and because the grid is getting cleaner, that means EVs get cleaner even after being manufactured and sold, whereas ICEs can only get cleaner through R&D and only get worse over time as they age (once they start burning oil, etc)
