Diesel has more NOx emissions and significantly more particulate emissions than cars running on gasoline, which is why cities are banning older vehicles running on Diesel. They’re harmful to people’s health, especially if they lack modern filters.
For CO2 though, Diesel usually runs miles around gasoline. That’s why the EU has favored Diesel engines over gasoline one’s since signing and ratifying the 1997 Kyoto protocol to reduce greenhouse emissions.
CO2 is directly related to fuel economy (no filtration of it) which is why diesel do better than gas. OP has a 40 years old diesel truck though, I wouldn’t expect it to be getting that great fuel mileage, especially not if they’re from the US.
Fair enough, older cars absolutely have worse fuel economy. I wonder how much this is offset by US trucks growing in size and weight though - a modern gasoline truck may even have worse fuel economy despite 40 years of advances. Although that’s not a high margin to clear to be honest.
