I think we have to accept that no alternative to an internal combustion fired car is going to miraculously avoid all forms of pollution - to provide the electricity to power a cars battery requires the electricity to be produced - although more and more of this is being produced in a “green way”, it still has a long way to go before it even reaches 50% globally. Then there’s the rare metals used to produce the batteries - there is considerable debate as to the true environmental impact of producing current, mainly lithium-ion batteries.
There has also been much talk about using hydrogen in fuel-cell vehicles and other power producing plants - these might yield only water as a byproduct, but producing hydrogen in the first place is currently very difficult - apparently only 5% of hydrogen production comes from “green” sources - this article provides many pros and cons of using hydrogen.

I for one accept that change is needed, but there’s no “magic wand” that’s going to make the world much more environmentally friendly than it is today, however any step in the right direction is a good one.
In fact as an example, yesterday I went to our local water bottling plant where you take your large 20 litre bottles, they clean them and fill them up for you while you wait. Being the good person that I am, I turned off my engine as I waited. Along came a “local” in his pickup and reversed next to my car and came out to get just 2 bottles refilled, but kept his diesel powered car engine running. The fumes from his car were not very pleasant, but had he an electric car, even had he left it running, there would have been zero pollution from the rear of his vehicle!!
