Improving the transparency of food products

The 2025 edition of the Open Food Facts Days was held on September 13 and 14 at the Académie du Climat in Paris, in a spirit of encounter, co-construction and commitment around food transparency. Participants from Europe and beyond gathered to exchange, learn and collaborate.

Day 1 began with presentations on the project's mission and values, followed by a moving debate. An ice-breaker allowed everyone to express their motivations. Several "lightning talks" presented various initiatives: the Recipe Estimator tool, NutraVerse, OpenDenmark, Open Prices, UX work, the forest footprint, etc. The afternoon was devoted to workshops in two tracks: "Beginner" for novices and "Open Everything Facts" to tackle strategic challenges (data reuse, mobilizing contributors, geographic expansion, etc.).
The Contributors' Trophies ceremony honored members who had made strong contributions to the project, and a convivial quiz rounded off the day before the traditional "Scan Party"!

Day 2 resumed with new lightning presentations: gamification of contribution, app news, data reuse, animal suffering footprint, etc. The morning workshops gave way to collective restitutions in the afternoon. Enthusiastic feedback was expressed, notably on the collaborative energy and richness of the exchanges.

Dear difters,

The year 2024 has been rich on many levels, with more initiatives, efforts and leadership from community members. ✨

Our mission is to bring more transparency to the food sector by opening up data on food products and prices, and encouraging food players, such as manufacturers, to be more transparent too.

As the new year begins, we look back on the year and celebrate the achievements of the Open Food Facts community!
