I pulled together as much information as I could find to check CO and NO emissions for gas vs. diesel engines and to determine how much effect refinery emissions contribute.
Refinery emissions/mile are negligible compared to the vehicles themselves.
I also ran across some information on actual NOx emissions from diesels in Europe vs. spec. They're all running about 3 times the spec values, on road.
Guess that means the spec are unrealistic for diesels. Could also mean that diesels may be legislated out IF THEIR SPECS ARE REALISTIC. Cities in Europe are getting choked by acid air. So guess they are.
