Naturally, as the name suggests, the Green Warranty rewards owners of lower CO2 emitting vehicles.

For example, a MINI One produces Tax Band C emissions of 128g/km, or approximately 2.3 tonnes of Carbon Dioxide for every 10,000 miles travelled.

With a Green Warranty, the Company's most comprehensive ExtraCare cover would cost £237.11 and include a £23.69 carbon offset contribution to the Carbon Footprint UK Tree Planting project.

However, even if your car falls into one of the highest tax bands, you can still be greener, because you will be able to offset your emissions and adhere to our "Green Motoring Charter".

The off-set contribution is calculated by multiplying estimated annual mileage by the average carbon emissions for the vehicle's Tax Band. Figures are based on the accepted guidelines provided by DEFRA and calculations provided by The Edinburgh Centre for Carbon Management (ECCM) (www.eccm.uk.com) - Europe's leading centre of expertise in carbon management.

To help illustrate how the Green Warranty works, we've compiled a table of popular models.
