1. Evidence-based certification

Effinature is an independent biodiversity certification, issued by IRICE, an organization accredited according to the ISO 17065 standard. It certifies the actual ecological functionality of a real estate or development project: continuities, habitats, vegetation, soils and water management.

Each certificate is based on:

• a field audit,
• an independent technical review,
• a certification decision under external control.

No opinion. No bias. Just the evidence.

2. Measured and transparent costs

Since January 1, 2025, Effinature pricing is public and defined in the reference document FORM_EFNAT_10-A_TARIFICATION_EFFINATURE v25.01. The amounts are calculated from objective criteria: surface area, number of deliveries, and project typology.

Basic pricing schedule (NCO and EVO – construction / rehabilitation)

Each additional delivery phase adds 50% to the base amount.

Accommodation scale (HOR)

Each additional delivery applies the same principle of 50% per tranche.

These costs are below the market average while incorporating all the checks required by the ISO 17065 standard.

3. A structured and verifiable process

The Effinature certification follows three standardized steps:

1. Initial assessment – ​​50% of the total cost.
2. Final assessment – ​​25%.
3. On-site compliance check – €2,250 per delivery phase.

Each phase corresponds to an independent and documented audit. The project is only definitively certified after validation of all conformities. This provides complete traceability, from the permit application to delivery, in accordance with Article L.433-1 of the French Consumer Code.

4. A limited financial impact, a lasting effect

On average, Effinature certification represents 0.5% of the total cost of a project. This low ratio produces a measurable effect:

• rationalization of plant pallets;
• elimination of invasive species;
• compliance with European biodiversity strategies;
• ESG valuation and sustainable finance.

Effinature does not weigh on the project: it lends credibility to it and aligns it with regulatory requirements.

5. Continuity over time: the High Ecological Value (HVE) standard

Effinature now incorporates post-delivery monitoring via the HVE standard. This system ensures the maintenance of functional biodiversity throughout the project's lifespan.

HVE scale (post-certification monitoring)

This monitoring, renewed every two years, ensures that the commitments made during the construction phase are sustained over time. Effinature thus becomes a living certification, consistent with the ecological reality of the sites.

6. How IRICE uses funding

Every euro donated to IRICE funds quality and research, not communication. These funds cover:

• the internal quality system (full-time quality manager),
• the annual audits by Cofrac,
• monitoring compliance with Code L.433-1
• research and development of new indicators,
• training and scientific dissemination to stakeholders in the sector.

This rigorous use ensures that certification funds competence, verification and transparency, in accordance with IRICE's mission of public interest.

7. Accreditation: a precise and clearly defined term

Many people use the word accreditation without fully understanding its scope. In French law, according to Article L.433-1 of the Consumer Code and the ISO/IEC 17011 standard:

Only organizations recognized by a national accreditation body can call themselves “accredited”.

In France, this single authority is Cofrac. Any “internal accreditation” or “network authorization” has no legal value.

Thus, IRICE is the only Cofrac ISO 17065 accredited body in the field of real estate biodiversity, which makes its certificates recognized, audited and enforceable.

8. Total impartiality

Effinature is based on three distinct functions:

1. AMO Biodiversity Partner: consulting for the project owner;
2. Independent evaluator: analysis and site visit;
3. IRICE: final certification decision.

No dual roles are permitted. This strict separation prohibits any conflict of interest and ensures absolute independence. It is one of the cornerstones of the Cofrac system.

9. An accreditation that opens up green finance

Thanks to its ISO 17065 certification, Effinature is a regulatory reporting tool. It integrates with:

• CSRD/SFDR obligations,
• green financing / Green Fund,
• criteria of the European Taxonomy,
• and investors' ESG frameworks.

Investment funds and financial institutions recognize IRICE as a state-accredited trusted third party.

10. Transparency, the hallmark of IRICE

IRICE is one of the only organizations in the sector to publish its complete certification fee schedule. This price transparency stems directly from accreditation: it proves that IRICE's business model is fair, auditable, and sustainable.

Each certification funds proof, research, and trust.

11. In conclusion

Effinature is a public-interest certification that is recognized, auditable, and accessible. Its cost is transparent. Its funding is traceable. Its independence is guaranteed.

Proof costs little. Lack of proof costs a lot.
