Why accredited biodiversity certification — and not just a label?
The 2026 regulatory framework
In 2026, the Green Taxonomy, CSRD ESRS E4 and Directive 2024/825 converge on a common requirement: environmental claims must be verified by an accredited body. What only an ISO/IEC 17065 certification can provide.
The 2026 regulatory context: what is changing for biodiversity
Three European texts converge in 2026 to transform the legal status of biodiversity claims in real estate. Together, they impose a level of evidence that declarative commitments and association-based labels can no longer satisfy.
Directive 2024/825
27 September 2026
Environmental claims must be verified by an accredited body. Penalties can reach 4% of annual turnover.
Taxonomy DNSH objective 6
In force
Taxonomy alignment requires auditable documentation of the absence of significant harm to biodiversity.
CSRD ESRS E4 + SFDR PAI
Fiscal year 2025-2026
Biodiversity data integrated into reporting must be consolidatable, traceable and produced by a verifiable process.
For real estate stakeholders, the consequence is direct: communicating on the biodiversity of a project without relying on a certification issued by an accredited body exposes one to increasing legal risk. The regulatory framework now clearly distinguishes enforceable evidence from declarative claims.
What an ISO/IEC 17065 accredited certification guarantees
The table below summarises the structural differences between an association-based approach and an accredited certification under standard ISO/IEC 17065, verified by Cofrac.
| Criterion | Association-based approach | ISO/IEC 17065 Cofrac Certification |
|---|---|---|
| National accreditation | None | Yes — Cofrac No. 5-0655 |
| Reference standard | Internal proprietary standard | ISO/IEC 17065:2012 |
| Separation of assessment / decision | Variable, often absent | Mandatory — §5.2 |
| Periodic external oversight | None | Regular Cofrac audits |
| Regulatory enforceability | None | Yes — Regulation 765/2008 |
| Insertable in technical specifications | Litigation risk | Yes — established legal framework |
| Admissible for CSRD / SFDR / Taxonomy | Limited evidential value | Auditable and consolidatable data |
| Standard transparency | Variable | Public and downloadable standards |
The 4 questions every decision-maker must ask about a biodiversity approach
Before committing to a biodiversity approach, four structural questions allow you to assess the robustness of the proposed framework.
1. Is the certification body accredited by Cofrac?
Verifiable in two minutes at www.cofrac.fr. If the body appears in the directory with an accreditation number and a scope covering product certification in biodiversity, the certification is accredited. Otherwise, it falls under a private framework.
2. Are the assessment, consultancy and decision functions separated?
ISO/IEC 17065 requires that the certification decision be made by a person distinct from the assessor. The certifying body structurally separates certification from consultancy. This separation eliminates the risk of complacency.
3. Are the standards public and downloadable?
Transparency of assessment criteria is a condition of trust. A project owner must be able to verify in advance what is required, and third parties must be able to verify the consistency of the outcome.
4. Can the certification be included in technical specifications without litigation risk?
Only a certification resting on an established legal framework (Regulation 765/2008, Public Procurement Code) can be included in public procurement. Association-based approaches expose the buyer to risks of favouritism or unjustified restriction of competition.
Effinature: all 4 answers in a single framework
Effinature certification is issued by IRICE — Cofrac Accreditation No. 5-0655, Product, Process and Service Certification, scope available at www.cofrac.fr.
Cofrac accreditation
Cofrac No. 5-0655, verified through periodic audits. Scope available at www.cofrac.fr.
Structural separation
Technical assessment and the certification decision are carried out by distinct individuals, in accordance with §5.2 of ISO/IEC 17065.
Public procurement
Insertable in technical specifications — documented use case with Europolia.
For multi-asset portfolios, the Biodiversity Performance Score (BPS) produces consolidated scoring that directly feeds ESRS E4 and SFDR PAI indicators. The combination of Effinature (asset by asset) + BPS (portfolio) constitutes the complete ecological evidence chain, from design to extra-financial reporting.
