by Marjolijn Vos, Wendy Van Lippevelde, Hendrik Slabbinck, Anneleen Van Kerckhove

WWF has been granted the 4-year Eat4Change project, funded by the EU Development Cooperation. Eat4Change wants to engage citizens on the topic of sustainable food, demonstrating how individual lifestyle choices can directly contribute tolimiting warming to 1.5 degrees, and support the achievement of the Sustainable Development Goals. To engage youth as“active global citizens”, sustainable food consumption is used as a lens and focus of the project. One part of the Eat4Change project is the evidence base output, which will create a consolidated scientific base thatinforms all Eat4Change interventions, creating momentum for sustainable dietary change. This report carries out part ofthe first work-package by conducting a systematic literature review on effective behavior change interventions. Literaturewas reviewed on existing food consumption behavior change interventions, more specifically on behavior changeinterventions that focus on meat reduction or shifting preferences and choices from animal-based to plant-based diets. The report not only gives an overview of the literature, but also aims to categorize the different interventions and working mechanisms according to the Socio-ecological model (Kok et al., 2008) and the Taxonomy of behavior change methods by Kok and colleagues (2016). You will find more insight in these theories in section 3.1 in the report.
