Fuel duty ('fuel tax')
The main financial incentives that support green cars and fuels include: reduced fuel duty ('fuel tax') on most green fuels; reduced vehicle excise duty (VED or 'road tax') for cars with lower emissions; and London Congestion Charge discounts for the greenest cars.

Fuel excise duty (fuel tax) incentives have been widely used by the UK government to reduce costs for green vehicle fuels. For example, the LPG vehicle market has been mainly driven by the low duty rates for gaseous fuels. With a fuel duty of around 6.6p/litre, the fuel duty benefit is around 42p/litre when compared to petrol. Taking into account LPG's lower energy content and higher production costs, an LPG car's fuel costs are around 30% less than for a petrol car.
