A Japanese study shows that a kilogram of beef causes more pollution than driving for three hours while leaving all the lights on back home.

The study team was led by Akifumi Ogino of the National Institute of Livestock and Grassland Science in Tsukuba, Japan. They counted the cost to the earth of raising cattle through conventional farming, killing the animal and shipping the meat, New Scientist reported on July 21.

Producing a kilo of beef creates the equivalent of 36.4kg of carbon dioxide (CO2), the principal greenhouse gas, Ogino found.

Most of these greenhouse-gas emissions take the form of methane, released in cow waste.

That one kilo of beef also needs the same energy needed to light a 100-watt bulb for nearly 20 days. The energy is needed to make and ship the animals' food.

The study appears in full in Animal Science Journal.
