Going Vegetarian Could Halve a Consumer’s Food Related Carbon Footprint


A new study of more than 50,000 people in the United Kingdom shows that going vegan, vegetarian, or even “pescatarian” can drastically reduce people’s carbon footprints.

Published in the journal Climatic Change, the study concluded that if people eating more than 100 grams of meat a day went vegan, their food-related carbon footprint would shrink by 60 percent.

If a person eating more than 100 grams of meat per day — and U.S. consumers eat about 225 grams daily — cut down to 50 grams per day, their food-related CO2 emissions would fall by a third, the study said.

Pescatarians, who eat fish but no other meat, generate only 2.5 percent more CO2 emissions than vegetarians, according to the study. The research also concluded that vegans produce 25 percent fewer CO2 emissions than vegetarians, who still eat eggs and dairy. “

In general there is a clear and strong trend with reduced greenhouse gas emissions in diets that contain less meat,” said Oxford University researcher Peter Scarborough, a co-author of the study.
