Climate labels on fast-food menus can help steer people in the US away from ordering beef — the food with the worst impact on the climate — and towards meals that are better for the planet, according to new research.
Food systems contribute roughly a third of global greenhouse gas emissions, and much of it coming from raising cows and other livestock. As people look for climate solutions to rapidly cut down their greenhouse gas emissions, “one of the biggest changes we can make is reducing the red meat we consume,” says Julia Wolfson, an associate professor at Johns Hopkins Bloomberg School of Public Health and one of the researchers behind the new study.
