Description

Reducing plate waste in hotels - which interventions are most effective? This project aims to quantify the comparative effectiveness of belief-based and choice-architecture-based interventions in reducing food waste generated by tourists at hotel buffets. Expected outcomes include: new insights into effective triggers of pro-environmental tourist behaviour; the first empirical data on carbon emissions caused by plate waste in tourism; an automatic plate waste measurement system and benchmarking app for monitoring and comparison; and effective practical measures to reduce avoidable food leftovers generated by tourists. This should provide significant benefits by: lowering food cost for the struggling tourism industry, reducing carbon emissions, and contributing to Australia’s aim of halving food waste by 2030.. Scheme: Linkage Projects. Field: 1506 - Tourism. Lead: Prof Sara Dolnicar
