2022 – Edo, a participatory data physicalization of the climate impact of dietary choices

Edo is a participatory data physicalization meant to enable a small community to track the carbon impact of their dietary choices. Each type of food item is represented as a token, a disk, whose surface area encodes the carbon impact of a typical portion of that type of food (data source: Agribalyse). After a meal, one can add data by selecting tokens for all the types of food one just consumed. For example, a burger with fries would require a beef token, a bread token, a salad token, and a potato token. All tokens are then added to the board which can have different layouts. The first image shows a grouping by day, where each column shows the impact of food consumed by the people who contributed data that day. The second image shows a grouping by person, where each circle belongs to one person and illustrates the total carbon budget per person for 5 days if one was aiming to remain within a 2t yearly budget.

This project was presented as a pictorial at the ACM TEI 2023 conference. A video of the presentation given by Kim Sauvé is available on Vimeo.
