Evaluation of a community-based food waste campaign using a national control group.

Communities are increasingly interested in bolstering sustainability by implementing local campaigns to reduce wasted food and divert it from landfills. Evaluation can be challenging, however, as community-engaged interventions may reach all community members, making it difficult to find an appropriate control group. We leverage a recently validated online survey instrument with samples from both the treated community of Upper Arlington, Ohio, USA, and from the United States at large to provide an additional mode for assessing community-based campaign efficacy.
