Founded in 2021 following a broad mobilisation of civil society — bringing together scientists from diverse disciplines, consumer organisations, environmental NGOs, as well as student and farmer collectives — Planet-score® was created to inform consumers in a clear, nuanced, and unbiased way. The label is designed to be transparent and accessible, without oversimplification, while providing food companies with the tools they need to improve their products through eco-design.
To ensure the long-term independence, expertise, and integrity of Planet-score®, the brand is owned by the Solid Grounds Endowment Fund. The Fund has licensed its use to Planet-score SAS, which manages the deployment of the label on food products. Today, Planet-score® collaborates with over 300 brands, both in France and abroad (30 countries), covering 200 million packages and more than 135,000 food products listed in the free UFC Que Choisir mobile app. This makes Planet-score® the leading independent environmental label in the sector.
The Fund’s complete independence from companies, industry groups, and trade unions guarantees that the Planet-score® brand is used strictly in the public interest and in the service of consumer transparency.
Planet-score® is one of the four pillars of the Fund’s mission: restoring trust in the agri-food value chain, from farm to fork. Across consumer surveys in France and other European countries, this trust consistently hinges on the total independence from both economic actors and public authorities. The Fund receives no public subsidies, and donors have no influence over its activities.
This system enables all stakeholders — from upstream producers to downstream distributors — to take concrete action and rise to the challenge of building a sustainable agri-food sector.

ewö answers consumers’ questions about how (un)natural and artificial today’s food offerings are. These concerns are growing, because scientific evidence clearly shows that the rise in consumption of ultra-processed foods—now observed almost everywhere in the world, to varying degrees—is consistently accompanied by a parallel, synchronous increase in health problems (overweight, obesity, type 2 diabetes, hypertension, dental health issues, mental health, etc.).
It’s not easy for consumers to find their bearings, since many food products carry “health” claims, while it’s hard to tell which are simply processed and which are ultra-processed.
ewö was created to clear this up and provide that information. It is a composite indicator that places products on a scale of ultra-processing—reflecting their level of “junk food.”
