From the little I know, the US considers it more polluting because of whatever unique emission profile. Europe thinks the better mileage more than negates that and in fact makes it better. After VW dieselgate, I think the US’s view is considered correct.
Also iirc from what I’m told, Diesel had a bad reputation after poor engines in the 60s.70s or so So on a personal level it wasn’t popular in the 80s 90s etc. Car makers responded and didn’t use them in cars - now it’s pretty much only VW for diesel cars. Engines are better now but the trend carried even if the reason is forgotten. Big rigs and big ass trucks to haul RVs require it.

Also gasoline was already being adopted as an idustrial standard by the time Rudolf Diesel invented his engine.
Lol funny that there’s a circumstances where polluting is an actual argument held over big oil
