Not much to say about this really. The numbers speak for themselves.

Producing 2.2lb of beef generates as much greenhouse gas as driving a car non-stop for three hours, it was claimed yesterday. Japanese scientists used a range of data to calculate the environmental impact of a single purchase of beef.

Taking into account all the processes involved, they said, four average sized steaks generated greenhouse gases with a warming potential equivalent to 80.25lb of carbon dioxide. This also consumed 169 megajoules of energy.

That means that 2.2lb of beef is responsible for greenhouse gas emissions which have the same effect as the carbon dioxide released by an ordinary car travelling at 50 miles per hour for 155 miles, a journey lasting three hours. The amount of energy consumed would light a 100-watt bulb for 20 days.
