"Since the amount of VED is actually (allegedly) linked to emissions, it would seem to be fair that those are included too."
BUGGER!
(it was off topic to begin with!!!)
Well, there was green petrol in the same way as there is red diesel, but that finished after WWII.
Well, it never had emissions problems back in the 1920's? it just chugged and banged. It's over 90 years old and deserves a little more respect from the DVLA and government. it was around before either of them! It runs better than either of them too!
Bob, did you mean TVO? or red diesel, I got a friend that makes TVO for his fordson N tractor.
