Buying a luxury car is generally an unpoular decision when it comes to being green, and helping the planet. However it doesn't have to be this way, as there are actually many green options when selecting a luxury car. One good way to help preserve the environment is to select a used car, so no additional CO2 are relased during the manufacture of a new one.
Below are all luxury cars that have been assessed by autosanity.com, in order of the ownership CO2 levels. This means the estimated CO2 levels that will be produced for the average ownership term of 3 years, travelling 12,000 miles per year. Figures include purchasing, servicing, and repairs, but not insurance. All figures are estimates, and the real costs will depend on driving style, and condition of vehicle.
