Biodiversity and sustainable real estate news
Nature in the city has become a widely accepted fact. But while local authorities are increasing their commitments, sharing experiences, and launching pilot projects, a central question remains: what methods can guarantee the actual ecological performance of an urban project, beyond mere intentions? In a context where urban biodiversity is becoming an ESG assessment criterion, simply planting trees is no longer enough. What rhetoric may seem to solidify, only legally binding certification can demonstrate.
Nature in the city: a now established consensus
The benefits of urban greening are now known and validated:
- thermal regulation,
- reduction of urban heat islands,
- air quality,
- rainwater infiltration,
- public health and well-being.
Local authorities, developers, landlords and planners alike have understood that nature in the city is not an option, but a condition for resilience.
What's hindering scaling up: the lack of a measurement framework
Despite technical guides, biodiversity atlases, and green and blue infrastructure, operational deployment remains limited. Why? Because projects are rarely evaluated using a shared and verifiable methodology.
To certify the ecological performance of a project, it is necessary to go beyond descriptive tools: reproducible indicators are needed, integrated into an enforceable evaluation grid.
What technical tools cannot do: the ecological performance audit
Many initiatives exist to support urban greening:
- choice of suitable wood species,
- soil diagnostics,
- guides to differentiated management.
But these tools cannot certify that a site has:
- regenerated measurable ecological functions,
- improved the coexistence between human uses and ecosystems,
- contributed to a ZAN trajectory or to the Global Biodiversity Framework.
Without a framework for urban biodiversity certification, projects remain assessed by sight, not by evidence.
Effinature: a certification method at the service of local authorities
Developed by IRICE, Effinature is an independent environmental certification standard, compatible with the following requirements:
- of the GBF (Global Biodiversity Framework),
- of the European green taxonomy,
- regulatory ESG reporting.
The method is based on:
- a living diagnosis of the site
- a functional reading of pressures,
- a measurable trajectory of ecological restoration,
- and an independent audit by a third-party organization.
Effinature does not replace technical tools. It gives them contractual scope.
Towards a new standard: measuring to arbitrate
In the coming months, local authorities will no longer be judged solely on their will. They will have to prove the real effectiveness of their actions:
- de-waterproofed surfaces,
- active and connected frames,
- biodiversity sustainably established.
Simply planting vegetation will no longer be enough. It will be necessary to demonstrate its effectiveness.
IRICE supports this transformation, in complete independence, to guarantee that each project can prove its real ecological compatibility.
