As an environmental leader, why does The Prince of Wales drive around in a Bentley and own an Aston Martin?
The Prince does not own or choose to drive around in a Bentley. The car is required for some engagements for security reasons and is owned by the Metropolitan Police. Normally, The Prince and The Duchess are driven around in a Jaguar XJ diesel, his main official car.
In order to reduce net emissions from car travel, The Prince's Aston Martin runs on bioethanol made from wine wastage and a by-product of cheese-making.
