I may be wrong but I thought the pollution from our diesels was lower than theirs and aren't the emissions less from the new diesels than from a gasser?
I believe it is a particulate thing. Also part of the problem is how any are modified after for more power etc.
Another thing you see mentioned is noise. Diesels are still fairly noisy. Gassers less and electric dead quiet. From what I hear even busy Norwegian cities are becoming very quiet places. I know both our electric vehicles have "noise makers" so they generate at least a gentle humming sound to warm pedestrians.
from the results of the VW diesel scandal, at least currently U.S. standards for passenger diesels are more stringent than europe.
For new U.S. passenger diesels particulates are virtually non existant. And as far as noise, I'd say the latest diesels are just as quite as a gas engine.
Comercial U.S. vehicle diesels are currently higher emissions than passenger cars or light trucks. And they tend to be driven for decades so it is hard to get older ones off the road.
California enacted rules on use of older diesels in certain areas, and the non compliant trucks ended up being moved out of state, Oregon being one state that is now seeing many of them registered in.
