Official title
Testing Climate Impact Menu Labels Influence on Nutrition Quality of Fast-Food Selections: A Pilot Study
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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 a hypothetical online meal ordering task using a survey which emulates the online menu of a burger restaurant chain. Participants will be randomized for exposure to menus featuring one of five labeling conditions. Secondary objectives include examining total greenhouse gas emissions per meal order and, through a post-order survey, perception of labels between the conditions.
