What we eat has a direct impact on the climate, yet for many young adults, the link between food choices and CO emissions remains abstract, distant, or guilt-inducing. CO nsequences Season 3, titled "CO mment tu manges?"
, tackles this gap through a Scientainment approach grounded in social psychology and digital storytelling.
The project brings together six pairs of Swiss scientists and YouTube content creators whose usual topics have nothing to do with the environment. Together, each pair co-creates a video exploring a specific aspect of sustainable food, from reducing meat consumption to cutting food waste and choosing local, seasonal products. By approaching audiences through familiar cultural spaces rather than scientific ones, the project reaches young francophone adults (15-35) who would not typically engage with climate or science content.
What sets CO nsequences apart is its methodology. Rather than delivering top-down messages, the videos place creators in a learning journey alongside scientists, making the knowledge relatable, non-prescriptive and actionable. This approach leverages parasocial relationships between creators and their audiences to shift attitudes, social norms and behavioural intentions around sustainable eating.
Beyond content production, Season 3 serves as a structured experimentation ground. A rigorous impact evaluation protocol, designed with social psychology researchers from the University of Lausanne and HES-SO, will document which narrative and behavioural levers most effectively move audiences from awareness to intention to act. The resulting learnings are designed to be transferable to other Scientainment projects.
