Greener fuels

You can also reduce the environmental impact of driving and lower your fuel costs by running your car on greener fuels.

• Biofuels (biodiesel and bioethanol) are mixed with petrol or diesel and all cars can run on petrol/diesel with up to five per cent biofuel blended in. Cars that can run on an 85 per cent blend of bioethanol (known as E85) are also available.
• Electric cars do not produce any emissions when they drive (but emissions are produced from electricity generation).
• Hybrid cars use a petrol engine combined with a battery and are very fuel-efficient without any compromise on performance.
• Liquid petroleum gas (LPG) cars are not available for purchase new in the UK but petrol cars can be converted. Converting an older petrol car can bring local air quality pollutant emissions more in line with more modern cars - but will only continue to do so if the conversion is well engineered and maintained.
