Now in @JEnvPsych #openaccess with lots of figures and cool appendices.

Our first question: what do people think is sustainable food? So we started with two surveys and qualitative interviews. Many people struggled with different aspects of sustainability (production process, transportation, packaging) 2/n

We wanted data about behavior, so we asked subjects to upload receipts of their shopping. Student assistants were asked to code the data. Hard work, still messy data. 3/n

We learned a lot from these & #39;scoping studies& #39;, including that data input should be easier. So in the next phase we asked subjects to enter the ingredients of their meals. 4/n

Now we could calculate environmental impacts much better, combining the ingredients with results from life cycle assessments (LCA) thanks to @ZigaMalek (check out the appendix for this data!) 5/n

Next step: an intervention! Inspired by the scoping studies we focus on health vs. environmental motivations. Here is the descriptive treatment (different ones for vegetarians, flexitarians, vegans etc) 6/n

And the procedural intervention, which linked to a recipe on the website of @voedingscentrum and a list of ingredients to replace 7/n

RESULTS: we find that the procedural health treatment has the most potential: one week later the environmental impacts of the reported meals were significantly lower. 8/n

Thanks to my co-authors and all the amazing students that helped along the way! 9/9 - end
