Can someone please explain to me how they decide what vehicles can and cannot go in the ULEZ zones? My old 59 plate volvo diesel CO2 of 119 g/km, road tax of £35 can't but my 2011 Mazda 3 CO2 of 144 g/km, road tax of £200 can. Is it as arbitrary as the year it was made?
Its about air pollution not CO2, that’s why diesels are banned.
from TfL:
“To be compliant a diesel car must have NOx emissions equal to, or less than, 0.08 grams per kilometre and Particulate Matter emissions equal to, or less than, 0.005 grams per kilometre.”
