You report that 1 kilogram of beef adds the equivalent of 6 kilograms of carbon dioxide to the atmosphere, plus other climate-change pollutants (21 July, p 15). One implication of this is that driving a car is “greener” than walking – if you’re a beef-eater, that is.
Chris Goodall writes in How to Live a Low-carbon Life: “Driving a typical UK car for 3 miles adds about 0.9 kilograms of CO2 to the atmosphere.” Walking the 3 miles instead would use about 180 calories. You’d need about 100 grams of lean beef to replace those calories, resulting in 3.6 kilograms of emissions – four times as much as driving.
