Paris, 15 April 2026
Carbon Maps, a software platform specializing in measuring the environmental footprint of consumer goods, today announces that it is the first platform to offer Coût Environnemental (environmental cost) calculation at scale for food products. Scamark, the E. Leclerc group entity responsible for developing and marketing own-brand products, is the first company to benefit from this offering across 6,000 of its references. The E. Leclerc group thus becomes the first retailer in France to adopt this new environmental indicator, backed by the Ministry of Ecological Transition, Biodiversity and International Climate and Nature Negotiations and ADEME.
The Coût Environnemental translates the overall impact of a product on the environment (climate, biodiversity, environmental health, resources) into a single, consumer-readable indicator. Based on LCA (Life Cycle Assessment) methodology enriched with food sector-specific indicators, the Coût Environnemental calculation can be tested via Ecobalyse, the open-source tool developed by the Ministry and ADEME.
A powerful platform at the heart of the initiative
Carbon Maps is currently the first commercial platform to have implemented the Coût Environnemental methodology at scale, making it possible to score entire product portfolios. To enrich the Ecobalyse online tool, Carbon Maps responded to the call for contributions launched in January, providing several hundred food ingredients modeled according to different variants (France, organic and default). These ingredients, integrated directly into the Ecobalyse tool and accessible to all, help enrich the Environmental Cost calculation at the national level.
Carbon Maps has also ensured that its own platform complies with the Coût Environnemental methodology, guaranteeing consistency between its calculations and those of the Ecobalyse tool. It is this dual contribution, to the public tool and to its own calculation infrastructure, that makes it possible today to score entire portfolios, rather than individual products alone.
A deployment rooted in a long-term collaboration
The partnership between Carbon Maps and Scamark, E. Leclerc dates back to 2023, initially focused on measuring the environmental impact of its private label products, and leading to the launch of Carbon'Info, Scamark's proprietary carbon impact indicator, in April 2025. Carbon'Info is now deployed across all 6,000 references in its own-brand range, covering the Marque Repère, Eco+ and Nos Régions ont du Talent brands. The Coût Environnemental builds directly on this work: the data collected, recipe modeling and supply chain structuring carried out under Carbon'Info provided the foundation on which this new indicator was calculated across the entire catalog.

This deployment takes place ahead of any regulatory requirement, positioning Scamark as a pioneer of environmental labeling in French mass retail.
Project voices
Rémi Girouille, Quality and CSR Director, Scamark, E. Leclerc:
“Since 2023, Carbon Maps has been a key partner in our approach to measuring and communicating the environmental impact of our products. Their expertise in product carbon footprint calculation methodologies, and their active involvement in developing the Coût Environnemental framework, gave us the confidence to deploy this new indicator on our drives, the E.Leclerc website and progressively on electronic shelf labels in store, across all 6,000 of our food products. After Carbon'Info, it was a natural next step.”
Jérémie Wainstain, Co-founder et Head of Science, Carbon Maps:
“The Coût Environnemental is a major methodological advancement: it does not reduce the impact of a food product to its carbon impact alone, but also incorporates its impact on biodiversity, environmental health and resources such as water. These are dimensions we know how to calculate at scale across complex agricultural supply chains. That is why it was important for us to contribute to the success of the Environmental Cost by making part of our data freely available in the Ecobalyse tool. The fact that Scamark, E. Leclerc is the first retailer to deploy this indicator at this scale validates both the methodology and the approach.”
Patrick Asdaghi, Co-founder et CEO, Carbon Maps:
“This deployment illustrates what we have been building from day one: a data infrastructure that enables actors in the food industry to move from measurement to communication, without friction. Our collaboration with the Ecobalyse team was not a compliance exercise: it was a co-construction. And it is precisely because this work was above all collaborative and transparent that Scamark, E. Leclerc was able to deploy the Coût Environnemental with confidence, ahead of its regulatory framework.”
Vincent Colomb, Co-lead of Ecobalyse, ADEME:
"Carbon Maps was one of the major contributors to the call for contributions launched by ADEME in early 2026, aimed at finalizing the technical foundation of environmental labeling and collaboratively consolidating and enriching the Ecobalyse tool. Their expert teams also provided broader support in strengthening the reliability of our work and data through numerous constructive feedback on Agribalyse and Ecobalyse."
About Carbon Maps
Carbon Maps is a B2B platform dedicated to measuring and managing the environmental footprint of food products and agricultural supply chains. Founded in 2022, the company supports manufacturers and retailers in product carbon footprint (PCF) calculation and life cycle assessment (LCA), carbon accounting (Scopes 1, 2 and 3), supplier engagement and decarbonization roadmaps. The Carbon Maps methodology is compliant with Ecobalyse for the Coût Environnemental calculation.
