CO2

This is the emission rating of a vehicle expressed as grammes per km. In general the lower the emissions the more environmentally friendly the car is and therefore the lower the tax liability to the driver., If you want to drive a 4x4 V8 vehicle, its generally going to cost you a lot more cash, than a 1.9 Diesel saloon car. The old addige cames to mind here of "you pay your money, and takes your choice!"
