Certify the biodiversity of your real estate projects

Why a developer certifies its biodiversity

The ecological quality of a project has become a leading commercial argument. Buyers, both private individuals and investors, compare programmes on their living environment, the presence of greenery, summer comfort and urban nature. Local authorities, for their part, increasingly factor biodiversity into the award criteria of their consultations and building permits. In this context, an accredited certification turns a brochure claim into verifiable proof, measured on site and recognised by an independent third party.

The difference from a self-declaration is decisive. A developer can claim that it adds vegetation, preserves soils or creates ecological continuity: without external verification, these commitments remain unprovable and expose the company to accusations of greenwashing. Effinature certification, by contrast, rests on a documented assessment and a decision made by an accredited body, which gives it enforceable value with lenders, buyers and public authorities.

Commercial differentiation and asset value

A certified operation stands out at every stage of its marketing. Upstream, the biodiversity commitment strengthens the case presented to local authorities and land developers during consultations. During the sales phase, the certificate becomes a clear reference point for buyers, in the same way as an energy rating. For an institutional investor, it feeds the asset's extra-financial reporting and supports its long-term value. Certification is not a cosmetic cost: it is an asset that follows the programme from land acquisition through to operation.

Securing your environmental claims

Regulatory and extra-financial pressure is accelerating: the CSRD directive and ESRS E4 standard on biodiversity, Article 35 of the French Climate and Resilience Act which frames environmental claims, and the growing expectations of local authorities and investors. Communicating about nature without proof is becoming a legal and reputational risk. By relying on third-party certification, you document your commitments with verifiable evidence and reduce your exposure. Effinature is part of the wider toolset run by the NORMAXIS group, from the pre-diagnostic through to a signed certification, covering your entire biodiversity journey.

Which standard for which operation?

Effinature offers several standards depending on the nature of your operation. The right choice depends on the type of project and its stage of progress:

• N New construction: NCO. For a new housing or office programme, or a mixed-use operation, the NCO standard assesses ecological performance from design through to delivery.
• E Renovation: EVO. For a renovation or refurbishment operation, the EVO standard measures the biodiversity gain brought to the existing building.
• H Land development: HOR. For land development operations and outdoor spaces at the scale of a district or a plot, the HOR standard assesses the ecological quality of the works.
• V In-use monitoring: HVE. To verify over time that the biodiversity created is properly maintained once the programme is delivered and occupied, the HVE standard supports the management phase.

The role of the Biodiversity Partner and IRICE

The assessment of your operation is not carried out by the developer itself: this is what guarantees its independence. On site, it is conducted by a Biodiversity Partner, a qualified ecologist who applies the standard in a consistent and objective way, based on concrete evidence: studies, plans, site surveys. The certification decision then rests with IRICE, the certification body accredited by Cofrac under number 5-0655. This strict separation between assessment and decision is the key to the certificate's credibility. To learn more about the body and its accreditation, visit the IRICE website.

How to start a certification

The path is straightforward: you create your account, submit an application to IRICE, and once the application is deemed admissible, a Biodiversity Partner assesses your operation against the chosen standard. IRICE then makes its decision independently and issues the certificate, which is listed in the public registry of certified operations. You then hold a recognised proof, ready to use from the moment your programme goes to market.
