Ten greenest small cars

 1. Volkswagen Polo Hatchback (02 on)

For Volkswagen green is Blue. Go for a Bluemotion model and you'll get a car that's been specially engineered to offer better fuel consumption and lower carbon dioxide emissions. It's one of the few cars in the UK that's exempt from road tax.

 2. SEAT Ibiza (02 on)

Europe's funkiest car maker got just about everything right when it launched the Ibiza. But it's only since the start of 2007 that an ultra eco-friendly model - in the shape of the Ecomotive - joined the line. Big MPG and no road tax to pay.

 3. MINI Hatchback (06 on)

MINI Hatchback is very eco-friendly and easy on the environment. Go for a car from late 2007 fitted with 'EfficientDynamics'. It's not only one of the coolest cars around, but one of the greenest.

 4. Toyota Aygo (05 on)

Aygo is Toyota's take on an urban runabout aimed primarily at active twenty-somethings. It has a frugal yet feisty three-cylinder engine, ultra-low running costs and superior quality to most cars in its sector.

 5. Citroen C3 (02 on)

This is one of Citroën's best-selling models, and with good reason. It's quirky, fun and comfortable to drive. There are astonishing deals available on seemingly permanent special offers, too.

 6. Peugeot 107 (05 on)

The 107 shares its 1.0-litre engine with the C1 and Aygo. The Peugeot performs as well as the Toyota and Citroen with subtle differences down to styling and price, but 107 is better equipped.

 7. MINI Clubman (07 on)

The MINI Clubman is a more practical alternative to the standard MINI hatchback. It's longer and offers more room for rear passengers and more boot space. It packs some neat design touches including, too.

 8. Citroen C1 (05 on)

C1 is Citroën's version of the Peugeot 107 and Toyota Aygo. It has slightly different looks and the specification levels are different, but otherwise it's essentially the same as the 107 and Aygo; it's even built in the same factory.

 9. Skoda Fabia Hatchback (07 on)

The handsome new Fabia sticks to what the original model has been doing since it was launched in 2000. It's attractive, well equipped and should be reliable - in short an appealing car to own. Most models in the range are green - Greenline is the greenest.

 10. Renault Clio (01 on)

Clio retains the classless character of the previous two generations. It offers buyers more choice than other small cars, with a huge number of trim options, a wide range of petrol and diesel engines - a great choice for going green on a budget.
