Summary
This study looked at whether adding climate-impact labels (like carbon footprint info) to fast-food menus can influence people to choose healthier meals. Over 6,600 adults in the U.S. completed a mock online burger order. Researchers measured the nutritional quality of their selections and the greenhouse gas emissions of the meals. The goal was to understand if such labels can guide better food choices, not to treat any disease.
