Supermini - choosing a environmentally friendly model
If you have a regular daily mileage and somewhere to install a home charging unit, an electric supermini is the best and most environmentally friendly option. Failing that a plug-in hybrid or low emission petrol diesel car would be a good choice.
The Next Green Car Rating, looks at a total emissions over the lifecycle of a vehicle and expresses the vehicleâ€™s impact as a score ranging from 0 for the greenest cars to 100 for the most polluting. This can be used to help you compare supermini models across technologies and help you narrow down the options.
