Biodiversity and
real estate investment
Natural capital is no longer a peripheral consideration. It is a critical infrastructure upon which the economic and operational continuity of the real estate sector depends. Investors who fail to integrate it into their decision-making processes expose themselves to increasing systemic risks.
The paradigm shift
For decades, biodiversity has been treated as an environmental externality—a matter of regulatory compliance, a box to tick in a CSR approach. This approach rests on a flawed premise: that nature is a secondary, externalizable variable, the absence of action on which would have no major consequences for economic viability.
Scientific and economic data now paint a radically different picture. Natural capital is a critical infrastructure —just like energy networks, transportation, and telecommunications. Three characteristics define it:
- Continuity: Critical infrastructure must operate without interruption. Natural capital ensures the continuity of ecosystem services (climate regulation, soil fertility, water purification, pollination) on which every real estate project depends, directly or indirectly.
- Interdependence: A degradation of natural capital at one point in the system creates cascading failures. The resilience of the real estate portfolio depends on the integrity of these interconnected systems, both locally and globally.
- Irreversibility: Unlike built infrastructure, certain types of damage to natural capital (loss of biodiversity, deforestation, soil sealing) cannot be reversed within the timeframes of asset ownership. Decisions are final.
For the real estate investor, this reality means: natural capital is no longer a subject of peripheral risk management, but a systemic risk factor that directly affects the viability, resilience and long-term value of portfolios.
The transmission mechanisms are multiple. Increased degradation of natural capital generates stricter regulatory restrictions (expanded protected areas, rising compliance costs). It affects access to ESG and SFDR financing, whose criteria become more stringent every year. It exposes investors to the risk of downward revaluation: assets located in areas of climate stress or low ecological resilience see their attractiveness and value decline. Finally, it creates a reputational risk: funds and asset managers that do not integrate biodiversity gradually lose access to capital from institutional investors.
The paradigm is changing: biodiversity is moving from the status of an environmental consideration to that of a critical infrastructure for financial decisions .
The lack of trust
If natural capital is critical infrastructure, then its assessment must meet the same standards of reliability and neutrality as any other critical infrastructure. However, analysis of current frameworks reveals a structural trust deficit —a lack of institutional credibility that renders biodiversity-based investment decisions deeply fragile.
Role confusion
The fundamental problem is that those who design and implement biodiversity strategies (developers, project owners, consulting firms) are also responsible for producing performance evidence. This creates an irreconcilable conflict of interest. External evaluation, when it exists, often comes from providers selected by the project owner themselves—a situation incompatible with the independence required for critical infrastructure.
Lack of enforceability
Voluntary initiatives (environmental labels, CSR commitments) do not produce legally binding data. Biodiversity impact statements are not verified by an independent third party. Investors have no certainty regarding the validity of the figures used in their decision-making models. In the event of a dispute or deviation from the commitments made, there is no neutral arbitration framework.
Regulatory and normative fragmentation
Frameworks are proliferating without harmonization: BREEAM, HQE, RE2020, NRE, DNSH, green taxonomy, SFDR, CSRD. Each defines "biodiversity performance" differently. Criteria change from year to year. Investors cannot reliably compare portfolios. Voluntary standards coexist without a clear link to regulatory requirements. This fragmentation signals a lack of scientific and methodological consensus—precisely what cannot be tolerated for critical infrastructure.
Lack of temporal continuity
One-off assessments (at the time of design or financing) provide no evidence of the sustainability of the results. No system guarantees that the performance reported at day 0 is still achieved at day 10 or day 30. For an asset held for 30 years, this is a critical weakness: the investor has no data on the actual evolution of biodiversity over time.
The 4 functions that must be separated
- Design and implementation of the biodiversity strategy (responsibility of the project owner)
- Support and advice during deployment (role of the technical expert)
- Independent evaluation of actual performance (accredited third-party certification body)
- Investment decision (investor responsibility, informed by valuation data)
When these functions are not separated, the credibility of the assessment collapses.
This lack of trust is not merely academic. It has concrete economic consequences: ESG investors are increasingly demanding independent proof before committing, creating friction in project financing. Prudential regulators (the Bank of France, European authorities) are requiring robustness standards for the data integrated into risk models. Voluntary standards are losing credibility with institutional players.
The required solution: a trusted infrastructure — an institutional framework that separates functions, produces verified and enforceable data, and ensures temporal continuity.
Trusted infrastructure
A trustworthy infrastructure for biodiversity assessment is based on five minimum requirements. IRICE was designed to fully meet them.
1. Traceability
Every data point used to assess performance must be documented, sourced, and verifiable. Investors must be able to trace the analysis back to the raw data. IRICE establishes a chain of responsibility: the data collector, the validator, and the certifier. There is no opacity.
2. Comparability
The data produced by IRICE uses harmonized methodologies and standardized indicators. An investor can therefore reliably compare the biodiversity performance of two projects, two portfolios, or the same project at different dates. This comparability is essential for building consistent risk models.
3. Enforceability
The results of an IRICE assessment are not voluntary declarations, but accredited technical opinions. They are binding on the certifier. In the event of a discrepancy between the certified performance and the actual performance, there is a framework for appeals, a revocation process, and a clear accountability. This enforceability creates an incentive for honesty.
4. Temporal continuity
IRICE does not produce a snapshot at a given moment. It creates an assessment record that is informed by repeated measurements over time. For long-term portfolios, this means: monitoring audits, documentation of changes in conditions, and periodic updates to the risk assessment. Biodiversity is not static; neither is the infrastructure of trust.
5. Clarity of boundaries
For each assessment, IRICE clearly explains what is covered, what is not, the methodological limitations, and any residual risks not addressed. The investor knows exactly the scope of the insurance they are obtaining. There is no ambiguity.
IRICE embodies this trusted infrastructure. As a certification body for products, processes, and services (Cofrac accreditation no. 5-0655, scope available at www.cofrac.fr ), we are an independent third party. We do not advise, deploy, or decide—we certify according to public criteria and traceable methodologies. Our independence, our accreditation, and our commitment to methodological stability enable us to produce the assessments that institutional investors demand.
We operate as a regulator of biodiversity in real estate, and not as a service provider.
Integrating biodiversity into investment decisions
Biodiversity plays a role at three critical points in the investment cycle. Each requires a specific approach and type of assessment.
Before the decision: Risk & Selection
Assessing the ecological resilience of assets being considered for acquisition
Challenge: To identify assets exposed to high biodiversity risks before committing capital.
Questions: Is the site located in a sensitive area? Is the surrounding natural environment degraded? Are there specific regulatory obligations (Natura 2000, wetlands)? What is the project's ecological resilience potential?
IRICE approach: Biodiversity resilience diagnosis, mapping critical ecosystem services, sources of external risk, and the project's ability to maintain its value in different ecological and regulatory evolution scenarios.
During the decision-making process: Allocation & Compliance
Validate compliance and optimize capital allocation
Challenge: To ensure that the project meets regulatory requirements (DNSH, SFDR, CSRD, green taxonomy) and fund criteria, while optimizing the biodiversity strategy.
Questions: Does the project benefit from appropriate conservation measures? Are these measures adequate and sustainable? How do they align with regulatory requirements? What is the risk/impact profile of the portfolio after this new asset?
IRICE approach: Certification of compliance with the applicable regulatory framework, assessment of the quality and sustainability of mitigation measures, rating of net impact (NNL or BNG according to the standards).
After the decision: Value & Resilience
Documenting long-term performance and protecting value
Challenge: To ensure that the biodiversity performance promised at the time of the decision is achieved, documented and maintained throughout the holding of the asset.
Questions: Are mitigation measures being properly implemented? Is biodiversity evolving as expected? Are there new regulatory risks? What is the value trajectory?
IRICE approach: Periodic follow-up audits, documentation of changes in conditions, updating of risk assessment, impact report delivered versus promised.
