Case Study: Marriott – Pledge on Food Waste Certification

This case study showcases how 55 Marriott hotels in the UK and Nordics implemented a comprehensive food waste reduction strategy aligned with The Pledge on Food Waste certification. By embedding standardized operating procedures, staff training, real-time waste tracking (via AI), and guest engagement measures, the initiative achieved a 25% reduction in food waste within six months. The programme also generated significant environmental and social benefits, including hundreds of thousands of meals saved and substantial CO₂ reductions, demonstrating how structured frameworks, technology, and workforce engagement can drive measurable impact across large hotel portfolios.
