Abstract
Results show that only the choice-architecture nudge significantly reduced the average meal carbon footprint—by 0.3 kg/CO2e per order (12%), driven by a 5.6 percentage point (13%) reduction in high-carbon meal choices.
Contexto
What changed: Food-delivery app menus were reorganized to display the lowest-carbon restaurants and dishes first, compared to a control platform where order was randomized. Comparison: Business-as-usual random ordering on a simulated food-delivery platform. Limits: Single simulated purchase task with real food incentive; does not track repeat orders or long-term habituation over time.
