This document provides guidance for evaluating interventions and policies designed to reduce the amount of household food waste. In this context, interventions are any activity – such as campaigns, changes to food packaging or products – that are being undertaken in order to prevent household food waste.

So far there are very few evaluations relating to household food waste (HHFW) prevention interventions, which means that there is a lack of evidence about the most effective ways to reduce the amount of HHFW in different contexts. This guidance aims to address this evidence gap.

The guidance is for anyone undertaking or studying interventions who would like to understand whether the intervention has been effective in preventing HHFW. Use of the guidance could also help understand why a particular intervention has been successful (or not, as the case may be).

The guidance is designed to provide a practical overview of the subject, covering the key steps of an evaluation:

  • Understanding the intervention in question
  • Designing the evaluation appropriately
  • Implementing and disseminating the evaluation

Links are provided to a range of useful resources: general evaluation guidance, as well as material specific to HHFW. A summary of good-practice tips is also provided.

In the future, use of this guidance should lead to a step-change in the quality of studies evaluating HHFW. This should provide evidence for policy makers and other decision makers to select the most appropriate approaches, so that they are able to reduce the amount of food wasted from households in a cost-effective manner.
