Cut your fuel bills by 24 per cent

The Department for Transport has launched a service which reveals the cars emitting the least CO₂.

Compiled in association with What Car?, the scheme is the latest part of the Department’s ACT ON CO₂ campaign to help tackle climate change.

People considering buying a new car can visit dft.gov.uk/actonCO2, search for the type they're looking for by category, transmission and fuel type and automatically get a list of the lowest CO₂ emitting models according to their requirements.

By choosing the car with the most fuel efficient engine in its class, drivers could reduce their engine's CO₂ emissions by 24 per cent and potentially save around a quarter on fuel costs.

The Best on CO₂ rankings were developed using emissions data from the Vehicle Certification Agency, the DfT Agency responsible for collecting the official test data on CO₂ emissions from cars.

The 14 car categories were developed by What Car? magazine, based on groupings used by the motor industry to classify cars and on their expertise following extensive reader research about perceptions of the market.

The categories are:

• Supermini
• Small family
• Family, Estate
• MPV
• Compact Executive
• Executive
• Coupe
• Open-top
• Hot hatch
• Compact 4x4
• Large 4x4
• Luxury
• Performance Car
