Carrot, stick, or both? Price incentives for sustainable food choice in competitive environments
The global food system is a significant contributor to greenhouse gas emissions, with current consumption trends proving unsustainable. This study investigates the effectiveness of pricing interventions—discounts, surcharges, and combined schemes—to promote sustainable food choices in a competitive, real-world university environment. Findings reveal that while discounts are ineffective and surcharges risk customer churn and negated environmental benefits through spillover, a balanced combined approach significantly reduces CO2eq emissions and increases vegetarian meal uptake without adverse effects on sales or revenue. These insights are critical for designing scalable and economically viable sustainability interventions in competitive enterprise settings.

YES
Pricing interventions equally effective across dietary habits. Entrenched meat-eaters can be nudged towards more sustainable choices.
STAFF
Senior staff (higher income) less responsive to price changes than students, indicating varied customer sensitivity.
EPFL: A Real-World Competitive Environment
The study at EPFL (18,000 individuals, 12 cafeterias, food trucks, off-campus options) represents a highly competitive real-world food environment where customers could 'vote with their feet'. This unique setting allowed the research to assess spillover effects and economic sustainability, providing robust insights beyond captive settings.
CRITICAL
Coordination for Impact: Interventions in isolation may simply redistribute unsustainable behaviors rather than reducing them. Coordinated, campus-wide strategies are essential to maximize climate benefits and avoid unintended spillover effects.

Your Implementation Roadmap
A phased approach ensures seamless integration and maximum impact for your customized sustainability solution.
Phase 1: Discovery & Strategy Alignment (Weeks 1-3)
Comprehensive assessment of current food service operations, existing sustainability initiatives, and organizational goals. Develop a tailored strategy for pricing interventions and supporting behavioral nudges.
Phase 2: Pilot Program Design & Setup (Weeks 4-8)
Identify pilot locations, standardize menus, and configure pricing systems for combined strategies. Train staff on new protocols and communication for transparency.
Phase 3: Controlled Pilot & Data Collection (Weeks 9-14)
Execute the combined pricing intervention in pilot cafeterias using a crossover design. Rigorously track sales data, revenue, vegetarian uptake, and GHG emissions per meal, alongside monitoring for spillover effects.
Phase 4: Analysis & Optimization (Weeks 15-18)
Analyze pilot results, evaluate environmental and economic impacts, and identify areas for refinement. Adjust pricing tiers, communication strategies, and menu offerings based on real-world data.
Phase 5: Scaled Rollout & Continuous Monitoring (Months 5+)
Implement optimized strategies across all relevant food service locations. Establish a framework for ongoing performance monitoring, impact assessment, and adaptive management to sustain long-term benefits.
