What it is
France’s coût environnemental expresses the lifecycle impact of a garment in impact points. The methodology covers climate, biodiversity, water and resources, pollution, durability-related factors, microfibre release and end-of-life effects. A higher score means a higher environmental cost.
Legal and display status
The calculation and communication method is governed by the decree and order of 6 September 2025 and launched from 1 October 2025. The French Ministry states that display remains voluntary for brands, but any communicated result must follow the official method and graphic rules.
Data brands should prepare
- Product category and mass.
- Fibre composition and material origin.
- Spinning, fabric formation, finishing and assembly geographies.
- Transport and distribution assumptions.
- Durability and commercial-practice parameters required by the method.
- Evidence, calculation version and publication date.
Why this belongs in the product data layer
The score is not a substitute for primary product and supply-chain data. Treat the calculation as a versioned derived result: retain inputs, method version, output and publication status. That lets the same governed catalogue support the product page, environmental display, DPP and internal scenario analysis.
