What exactly is an FDES?
FDES stands for Fiche de Déclaration Environnementale et Sanitaire. Think of it as France’s own extended-cut version of an Environmental Product Declaration. It bundles a cradle-to-grave life-cycle assessment with health data drawn from toxicological databases. The format is cemented in the NF EN 15804+A2 standard and must be submitted in French.
Why French projects insist on it
France’s RE2020 building code rewards low-carbon materials with up to 6 points on the overall energy-and-climate scorecard (Ministère de la Transition Écologique, 2025). Projects chasing those points need product-specific FDES documents, not generic database averages. Skipping the form can nudge your product off the spec list before the real price talks even start.
How an FDES differs from an EN 15804 EPD
Both documents share the same core LCA backbone, but the FDES adds three twists:
- A mandatory health section flagging VOCs and classified substances.
- A more granular breakdown of construction site impacts (A4 and A5).
- Publication exclusively on the INIES national database.

Data sources: INIES and nothing else
France centralises all FDES files on INIES, the public repository run by the CSTB. Once uploaded, numbers are locked for five years, and architects pull them straight into software like Pleiades and EQUER by clicking a single URL (INIES, 2025). If your product is not there, it is invisible.
Timeline to publication: realistic vs aspirational
Official guidance says a complete FDES can be produced in “about six months.” Market surveys show the median drags past ten months because data collection stalls in multi-plant supply chains (ADEME, 2024). Manufacturers who pre-compile utility bills, invoices, and transport maps often shave the schedule by 40 percent.
Choosing a partner to crunch the numbers
Three checkpoints separate the quick from the stuck:
- A bilingual LCA team that writes in French and references INIES taxonomy line-for-line.
- A proven workflow for supplier data capture. Email spreadsheets are too slow, regularly.
- An independent verifier approved by the Comité Scientifique to sign off in less than two weeks.
Key takeaway for manufacturers
The FDES is not just “a French EPD.” It is a sales passport stamped by regulators and trusted by every architect working under RE2020. Secure the data early, keep it clean, and your product sidesteps the budget-cut guillotine that claims less documented competitors. Missing the form? You might as well forget the French market altoghether.
