If this article is to be believed then our pets could have a bigger carbon footprint than the car we drive. According to the article the carbon footprint of a pet dog is more than double that of a sports utility vehicle. The analysis is based upon the fact that the average sized medium dog eats around 164 kilos (360 pounds) of meat and 95 kilos of cereal in a year. The land required to generate this amount or food has an annual footprint of 0.84 hectares, that’s twice the 0.41 hectares required by a 4 by 4 driving 6,200 miles a year. It appears other pets are no better for the environment, with cats having an eco-footprint of around 0.15 hectares, a little less than driving a Golf for a year. A hamster’s carbon footprint equates to a plasma TV and a goldfish, the equivalent to running two mobile phones. There are ways to reduce your pets carbon footprint such as feeding your cat on fish heads and left over's rather than premium choice cuts of meat. Still, given the choice between giving up my cats or the car, I know what I would rather keep, my cats might not be very useful but my car could never give me the companionship and entertainment that my cats do.
