From theory to practice: A toolkit for implementing nudges to increase sustainable food choices at academic events

Catering is a major contributor to the environmental impact of events, such as conferences and workshops, underscoring the need to promote sustainable food choices. To support practitioners in event and conference catering, we developed a comprehensive guidebook introducing the concept of nudging as a strategy to encourage sustainable food choices. The guidebook provides practical examples, step-by-step instructions for selecting and implementing nudges, and guidance on measuring their effectiveness. This offers the potential to encourage practitioners to integrate nudging approaches into their specific event catering settings, thereby promoting greater adoption of sustainable food choices.
