With the Ecological Awareness project, our main goal was to raise awareness among young people in Anderlecht about environmental issues and give them the tools to become agents of change. Our initial ambitions were quite broad: producing a video, organizing workshops in schools, and widely disseminating our creations. Very quickly, we decided to return to the essentials: developing genuine ecological awareness, learning through non-formal methods, and enabling young people to design concrete tools themselves. It was in this spirit that the idea of a playful tool was born. At first, it was supposed to be a board game, but after observing young people’s habits, we decided to adapt the project to their practices. We therefore created an online quiz, accessible via a QR code printed on recycled paper cards. This interactive and sustainable format allowed us to limit paper use while making the tool accessible beyond the project itself. Along the way, some unexpected challenges arose, particularly regarding gender diversity. Although we thought it was a given, it raised concerns among some parents. To address this, we set up two separate dormitories, which reassured families and enabled everyone’s participation. The experience ultimately demonstrated that a mixed project could run smoothly and that it represented a real asset in opening minds. Finally, to anchor our action within the neighborhood, we took part in the local community festival (with over 500 participants, including elected officials) and organized a photo exhibition in our premises, to which schools were invited. These moments allowed us to share our approach, raise awareness among residents on a large scale, and strengthen our role as ambassadors of ecology at the local level.
