The results of POPRASUS can expectedly be used by policy aiming to change diets into more sustainable directions. As environmental concern has explicitly been included in the nutrition recommendations only recently, the moment is advantageous to analyse the integrative logic of environmental and food policies.

The results also contribute directly to emerging scientific and societal debates on how the sustainable diet is defined and what are its barriers in everyday consumption and in institutional settings. By comparing alternative consumption groups at different stages of stabilisation, we are able to discern how the stage of stabilisation impacts on the negotiations between ecological/political and more privatised concerns as well as the do-ability of the practice. Moreover, the results and their communication in social media offer new insights into the debates over sustainable eating and its governance.

Our engagement with experiments provides readily usable knowledge on what is do-able with respect to sustainable diet in different settings, but experiments can also lower the threshold for action and make the processes of change more transparent, attracting thus new participants and resources. Systematic comparison of experiments, respectively, provides knowledge on how far they can reach in sustainability transformation and as tools for policy-learning.
