New research finds that, pound for pound, grazing cattle generate at least as much heat-trapping gas as those raised in feedlots.
New research finds that, pound for pound, grazing cattle generate at least as much heat-trapping gas as those raised in feedlots.
The study, published in the Proceedings of the National Academy of Sciences, modeled the emissions from grazing and feedlot cattle in the U.S., finding that even in the best-case scenario, grazing cattle are no better than their industrial counterparts.
That’s because grazing cows grow more slowly and yield less meat. To produce the same amount of beef as feedlot operations, ranchers must raise more cows over a longer period, which means more emissions per ounce of beef.
