This event will discuss ongoing research on interventions to reduce household food waste.
Reducing food waste is one of the key sustainability targets, and food waste in households constitutes a substantial part of the issue. Still, theory-driven research testing interventions to reduce household food waste and especially comparing different intervention options is rare. Moreover, in testing the effectiveness of such interventions, possible contamination caused by the measurement of food waste needs to be considered. The current study tests two interventions, based on the Motivation-Opportunity-Ability framework, to assess if combining a tool package to reduce food waste with a motivational message based on social norms is more effective than the tool package alone. Additionally, it examines the effects of the self-reported measurement of household food waste, to ensure that results are not caused by mere measurement. Findings of two field experiments show that the tool package improves food management abilities and opportunities, and decreases self-reported food waste. Results of the second study indicate that the effects are not due to mere measurement.
