Full description

This online randomized clinical trial will test the effects of restaurant menu carbon footprint labels on consumers' choices and perceptions of restaurant menu items. Participants will be randomized to see a restaurant menu with one of two labeling schemes: 1) Control: calorie labels only; 2) Carbon footprint labels in addition to calorie labels. Participants will be instructed to select an entree to hypothetically order from an online restaurant menu. After selecting, they will be asked to answer questions about their perceptions of menu items and carbon footprint labels.The primary outcome will be the average carbon footprint of menu items chosen from the online menu.
