If it’s commercial registered it’s double tax so what’s that got to do with CO2?
Also if your V5 states it’s a mini bus or camper then your road tax will be less more like half. Not sure what that has to do with CO2 other than maybe more usage which is hard to calculate from each individual user. They don’t take into account the CO2 produced by electric vehicles to charge them
Road Tax is calculated on CO2 emissions nothing to do with Euro engine emission standards.
