“20% of U.S. Diets Responsible for Almost Half of Country’s Food-Related Emissions, Study Finds”
"The study was the first to look at the environmental impact of individual diets in the U.S., and found that 20 percent of Americans account for 46 percent of the country's food-related greenhouse-gas emissions. Seventy percent of the emissions that resulted from the diets of that 20 percent came from meat consumption, according to a press release about the study published by the University of Michigan on EurekAlert!. The consumption of beef accounted for 72 percent of the difference between the highest and lowest 20 percent of emitters, the release also reported. Overall, the top 20 percent of diets caused 7.9 times the greenhouse gas emissions as the bottom."
