Appendix B
Literature Search Approach
Two sets of literature searches were conducted (in 2019) to inform the committee’s work. The first was conducted to identify implementation strategies to reduce food waste at the consumer level. The second was done to identify reviews, systematic reviews, and meta-analyses of drivers and strategies to intervene for consumer or household behaviors related to energy saving, recycling, water conservation, waste prevention, and diet change.
In order to obtain a more rounded set of results that accounted for differences in indexing practices and use of vocabulary in titles and abstracts, the first set was split into two groups. The first iteration explicitly included behavior-related terms and avoided prevention-related terms. The second iteration left out behavior-related terms and targeted prevention-related terms. Searches were conducted in six online databases: Agricola, Embase, Medline, ProQuest Research Library, PubMed, and Scopus. Articles were included if they were published within the last 15 years, available in English, peer-reviewed, and conducted in Europe or English-speaking countries. The search terms for both iterations are shown in Table B-1. The searches yielded 548 unduplicated articles from the first group and 234 unduplicated articles from the second group.

The second set of searches, which targeted other efforts to change consumer or household behaviors, was also conducted in two parts. The first focused on strategies to promote energy saving and recycling behaviors. The second was directed at strategies to promote energy saving, recycling, water use conservation, waste prevention behaviors, and diet change, but it was limited to systematic reviews and meta-analyses. Both sets of searches were conducted in ProQuest Research Library, PubMed, and Scopus. The first search on energy-saving behaviors included papers that were published within the last 15 years, and it was limited to reviews, including, but not limited to, systematic reviews from Europe and English-speaking countries. The second search used the same terms, but it was restricted to systematic reviews and meta-analyses that had been published in English since 2000. Search terms are presented in Table B-2. The first search yielded 380 unduplicated studies; the second search yielded 406 unduplicated studies.
