Prius is the world's highest selling Hybrid car, and it's been that for more than a decade now. This means Toyota has helped cut down emissions from consumer automobiles by a significant degree.
It's not the 1000 EVs out of the 100k vehicles that matter, but rather the 10k hybrid vehicles out of that same 100k pool, which literally produce double the MPG compared to ICE cars. It becomes obvious when we look at the total emissions generated by that pool of 100k cars.
If there's anyone to blame, I'd look at the luxury division - Mercedes, Audi and BMW (and also Genesis/Acura) - all late to the party, and still haven't been successful at meaningfully replacing the vehicles they would sell to their customers yet.
