Action on Climate Change: Alternative Motor Fuels

A number of alternative fuels are available for vehicles.


Biofuel or biodiesel is a renewable fuel made from crops such as rape, sunflower or soyabean. 100% biodiesel in cars can provide a 60% carbon dioxide reduction in emission and because it is biodegradable it will not build up in soil or waterways. Biodiesel is most commonly used in a 5% blend with standard ‘mineral’ diesel which provides a 3% reduction in carbon dioxideemissions. Using more than higher blends may invalidate your vehicles warranty, and may require adaptations to your vehicle.


Liquid Petroleum Gas is a combination of propane and butane which gives a 10-15% reduction in carbon dioxide emissions. With LGP nitrous oxide emissions are 80% lower and there are no particulate emissions. Cars can be converted to LPG. LPG costs about half the price of petrol and has a lower benefit in kind tax liability. LGP vehicles receive 100% discount on the London Congestion Change.

Hydrogen Fuel Cells

Fuel cell vehicles are not currently commercially available. Fuel cells work by turning hydrogen and oxygen into water, in the process creating electricity. Therefore, to be truly emission free the hydrogen must be generated by wind or solar power.
