It's better to green your diet than your car

"The typical US diet, about 28 per cent of which comes from animal sources, generates the equivalent of nearly 1.5 tonnes more carbon dioxide per person per year than a vegan diet with the same number of calories...

"It's better to green your diet than your car

17 December 2005

Thinking of helping the planet by buying an eco-friendly car? You could do more by going vegan, say Gidon Eshel and Pamela Martin of the University of Chicago.

They compared the amount of fossil fuel needed to cultivate and process various foods, including running agricultural machinery, providing food for livestock and irrigating crops. They also factored in emissions of methane and nitrous oxide produced by cows, sheep and manure treatment.

The typical US diet, about 28 per cent of which comes from animal sources, generates the equivalent of nearly 1.5 tonnes more carbon dioxide per person per year than a vegan diet with the same number of calories, say the researchers, who presented their results at a meeting of the American Geophysical Union in San Francisco last week.

By comparison, the difference in annual emissions between driving a typical saloon car and a hybrid car, which runs off a rechargeable battery and gasoline, is just over 1 tonne. If you don't want to go vegan, choosing less-processed animal products and poultry instead of red meat can help reduce the greenhouse load."
