A one year old Diesel car makes so much pollution per mile. You can't undo what was caused by making it or undo poor choices regarding recycling etc.
To scrap that perfectly good vehicle and replace it with an electric one produces more pollution. The level per mile is then less at the vehicle and probably less over all per mile. (Also it'll do fewer miles because of the hours it'll spend plugged in).
There is a break even point. The least pollution probably involves keeping the Diesel vehicle until worn out.
The break even point is not where green cultists and sellers of EV's want you to believe it is: every vehicle replaced now (and again in 18 months time for the sellers and again after that and... ).
There is additionally the efficiency of production. Older designs of EV and those made in small numbers will have the break even point later.
