The Environmental Working Group released its Meat Eater's Guide to Climate Change and Health on Monday, looking at the carbon footprint of eating beef, pork and poultry.
According to the study, if a family of four gave up eating steak for just one day a week, it would be the equivalent of taking their car off the road for three months.
"What our study shows is that people can have a significant impact on reducing their carbon footprint and also improving their health by just cutting back on meat, particularly red and processed meat," Environmental Working Group spokesperson Kari Hamerschlag said.
The Environmental Working Group does not advocate giving up meat entirely, just eating less of it and, if possible, locally grown, which reduces its carbon footprint.
