Justus Liebig University Giessen (JLU) has launched the project “Wandelkarte 2.0” in February 2026, marking its first initiative within the Living Peace Lab of the European University Alliance EUPeace. The one-year project aims to improve access to sustainable, fair and healthy food options in Giessen by developing a digital, user-friendly map that connects local initiatives and businesses.
Making sustainable food visible and accessible
Building on the existing “Wandelkarte” developed by the Fairtrade Town Giessen initiative in 2020, the project updates and expands a map that already lists over 90 locations offering fair, regional and environmentally friendly products, as well as repair and reuse options. The new version transforms this resource into an interactive digital tool, making it easier for residents to identify and access sustainable choices in their daily lives.
A key outcome of the project is the development of a scientifically grounded set of criteria to assess food-related businesses. Students at JLU, working closely with local stakeholders, are creating a framework that evaluates sustainability, social fairness and health aspects. This enables greater transparency and helps consumers make informed decisions.
A collaborative approach through Living Peace Labs
The project follows the Living Lab approach, bringing together researchers, students, local businesses and citizens in a shared process of testing and improving the tool. Rather than a one-way transfer of knowledge, the initiative fosters collaboration and practical experimentation to ensure the tool is relevant and easy to use.
As part of EUPeace, the project contributes to developing inclusive and just societies by linking academic expertise with real-world challenges. It strengthens cooperation between universities and local communities while promoting sustainable consumption at the city level.
Scaling impact beyond food
Following its implementation, the Fairtrade Town Giessen steering group plans to apply the developed criteria to additional product categories. This step-by-step expansion will further enhance the city’s sustainability map and extend its impact across different areas of everyday consumption.
