The primary objective of this study is to test the relative effects of climate-impact menu label designs on the healthfulness of consumers' fast-food meal choices. Participants will complete hypothetical online meal ordering tasks using a survey which emulates the online menus of two types of fast-food chain restaurants: a burger restaurant and a sandwich restaurant. Participants will be randomized the view both menus, presented in random order, with one of five labeling conditions applied. Secondary objectives include examining total greenhouse gas emissions per meal order, energy and nutrient content of meals ordered, prices of meals ordered, and, through a post-order survey, noticeability, and perceptions, and knowledge and understanding of labels between the conditions.
