The limitations of one-time policies in reducing food waste underscore the need for a more engaging, sequenced policy design. In this pre-registered field experiment, we test the effectiveness of a nudge with or without a thinking prompt in reducing food waste and generating financial savings, using a step-wedged design. 193 households in Fife Council, Scotland reported their food waste and grocery bills across 8 weeks (N=1081) and completed pre- and post-experiment questionnaires. The nudge group received a feedback report, and the week after, it was further encouraged to think about food waste reduction strategies (nudge+). Both interventions reduced household food waste compared to the baseline, on average. The nudge+ decreased food waste by 10g compared to the nudge, with a significant lagged effect in the post-treatment period. Planning, storage skills and disposal attitudes improved after the experiment. Policy sequencing can enhance the effectiveness of behavioural interventions in reducing food waste.
