Summary

This study aims to evaluate whether a dual-label intervention, combining carbon -coded footprint color labels and calorie information, can promote low-carbon and healthier food choices among university students in a real-world cafeteria setting. A randomized controlled trial will be conducted with approximately 200 participants, who will be assigned to either an intervention group (with labels) or a control group (without labels). The study a consists of 2-week baseline period, a 4-week intervention period, and a 2-week a follow-up period. The primary outcome is the mean carbon footprint level of selected meals, and secondary outcomes include nutritional quality, body composition, and changes in environmental and health awareness.

Carbon and Calorie label

Participants are exposed to carbon footprint and calorie information presented on labels attached to serving trays in a university cafeteria. The labels use visual cues (e.g., traffic-light colors) to indicate environmental impact and energy content of food items at the point of selection.
