In recent years, food sustainability has become a critical issue as the world faces the challenges of climate change, population growth, urbanization, and the impacts of climate change on food systems. Food systems contribute 19%-29% of greenhouse gas (GHG) emissions [1]. Adopting sustainable food behaviors can reduce GHG emissions. However, a gap is observed between pro-environment attitudes and actions, highlighting the need for support and knowledge to enable individuals to make sustainable food choices. To address this, I designed Cibus, a climate change intervention for family households in the home context. The system of Cibus includes a (1) data sculpture and a (2) smartphone application. Whereas the data sculpture provides general feedback on the climate impact of five categories of dinner intakes of a household, the smartphone application enables data logging and provides detailed information on the impact and additional support (e.g. chat function, recipes). By integrating the intervention into the home context, the place where shopping lists are made and food is stored, prepared, and consumed, Cibus stimulates a shared and collective approach on food sustainability. An initial 2-week field study with a family showed that Cibus provided knowledge, stimulated a change in behavior and facilitated shared and personal reflection.
