There is then a sliding scale based on CO2 emissions.
For petrol and diesel cars the minimum and maximum benefit charges on the standard scale are 15% and 35% respectively. From April 2008 a new lower 10% band was introduced for cars with emissions of 120g/km or less.
Starting level of CO2 emissions attracting the minimum 15% charge are under 135g/km up to a maximum of 35% for 235g/km and above.
Charge increases by 1% for each 5 g/km of CO2 emissions over the minimum.
Diesels attract a 3% supplement due to the emission of other poisons.
