A first-of-its-kind study has compared the carbon footprints of six of the most common diets.
It’s well-known that around a third of greenhouse gas emissions come from the food system, and that beef production is one of the biggest culprits – emitting around 10 times more gases than chicken.
But while the environmental burden of different foodstuffs is much discussed, less research has gone into how different diets – composed of a wide variety of foods – compare.
“Climate change is arguably one of the most pressing problems of our time, and a lot of people are interested in moving to a plant-based diet,” said Professor Diego Rose, senior author of the Tulane University study which also weighs up different diets ‘ nutritional quality.
“That would reduce your footprint and be generally healthy,” concluded the nutrition program director at Tulane University School of Public Health and Tropical Medicine. But
