Biodiversity and investment
decisions in real estate
Natural capital is no longer a peripheral consideration. It is critical infrastructure on which the economic and operational continuity of real estate depends. Investors who fail to integrate it into their decision-making processes expose themselves to growing systemic risks.
The paradigm shift
For decades, biodiversity was treated as an environmental externality — a matter of regulatory compliance, a box to tick in a CSR approach. This assumption rests on a flawed premise: that nature is a secondary, externalisable variable whose neglect carries no major consequence for economic viability.
Scientific and economic data now paint a radically different picture. Natural capital is critical infrastructure — on a par with energy networks, transport 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 Degradation of natural capital at one point in the system triggers cascading failures. The resilience of a real estate portfolio depends on the integrity of these interconnected systems, at both local and global scales.
- Irreversibility Unlike built infrastructure, certain forms of natural capital degradation (biodiversity loss, deforestation, soil sealing) cannot be restored within typical asset-holding timeframes. Decisions are final.
For the real estate investor, this reality means: natural capital is no longer a matter 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. Accelerated degradation of natural capital generates stricter regulatory restrictions (expanded protection zones, rising compliance costs). It affects access to ESG and SFDR financing, whose criteria tighten every year. It exposes assets to downward revaluation: assets located in zones of climate stress or low ecological resilience see their attractiveness and value decline. It also creates reputational risk: funds and asset managers that fail to integrate biodiversity progressively lose access to institutional investor capital.
The paradigm is shifting: biodiversity is moving from an environmental consideration to critical infrastructure for financial decisions.
The trust deficit
If natural capital is critical infrastructure, then its assessment must meet the same standards of reliability and neutrality as any critical infrastructure. Yet analysis of current frameworks reveals a structural trust deficit — a lack of institutional credibility that makes investment decisions based on biodiversity profoundly fragile.
Role confusion
The fundamental problem: those who design and implement biodiversity strategies (developers, project owners, engineering consultants) are also responsible for producing evidence of performance. There is an irreducible conflict of interest. External assessment, where it exists, often comes from providers selected by the project owner — a situation incompatible with the independence required for critical infrastructure.
Lack of enforceability
Voluntary schemes (environmental labels, CSR commitments) do not produce enforceable data. Biodiversity impact statements are not verified by an independent third party. Investors have no certainty as to the validity of the figures used in their decision models. In the event of a dispute or deviation from stated commitments, there is no neutral arbitration framework.
Regulatory and normative fragmentation
Frameworks are proliferating without harmonisation: 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 clear articulation with regulatory requirements. This fragmentation signals an absence of scientific and methodological consensus — precisely what cannot be tolerated for critical infrastructure.
Absence of temporal continuity
Point-in-time assessments (at the design or financing stage) produce no evidence of lasting results. No system ensures that performance declared at D+0 is still effective at D+10 or D+30. For an asset held for 30 years, this is a critical weakness: the investor has no data on actual biodiversity trends over time.
The 4 functions that must be separated
- Design and implementation of the biodiversity strategy (project owner's responsibility)
- Support and advice during deployment (technical expert's role)
- Independent assessment of actual performance (accredited third-party certification body)
- Investment decision (investor's responsibility, informed by assessment data)
When these functions are not separated, the credibility of the assessment collapses.
This trust deficit is not academic. It produces concrete economic consequences: ESG investors increasingly demand independent evidence before committing, creating friction in project bankability. Prudential regulators (Banque de France, European authorities) require robustness standards for data integrated into risk models. Voluntary standards are losing credibility among institutional players.
The required solution: a trust infrastructure — an institutional framework that separates functions, produces verified and enforceable data, and ensures temporal continuity.
The trust infrastructure
A trust infrastructure for biodiversity assessment rests on five minimum requirements. IRICE was designed to meet them in full.
1. Traceability
Every data point used to assess performance must be documented, sourced and verifiable. The investor must be able to trace from the conclusion back to the raw data. IRICE creates a chain of responsibility: the party that collects the data, the party that validates it, the party that certifies it. No opacity.
2. Comparability
Data produced by IRICE use harmonised methodologies and standardised 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 commit the certification body. In the event of a discrepancy between certified and actual performance, there is a recourse framework, a revocation process, and clear accountability. Enforceability creates the incentive for honesty.
4. Temporal continuity
IRICE does not produce a snapshot at a single point in time. It creates an assessment file that is enriched by repeated measurements over time. For long-term portfolios, this means: follow-up audits, documentation of condition changes, periodic updating of risk assessments. Biodiversity is not static; the trust infrastructure is not either.
5. Clarity of scope
For each assessment, IRICE clearly states what is covered, what is not, the methodological limitations and the residual risks not addressed. The investor knows exactly the scope of the assurance obtained. No ambiguity.
IRICE embodies this trust infrastructure. As a product, process and service certification body (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.
It is as a regulator of biodiversity in real estate, not as a service provider, that we operate.
Construction carbon: the climate dimension of real estate investment
Biodiversity is not the only environmental challenge that real estate investors must document. Construction carbon — emissions generated during the construction phase — represents a growing share of real estate assets' carbon footprint, and reporting obligations are multiplying: ESRS E1 (CSRD), BEGES scope 3, RE2020, EU Taxonomy.
IRICE covers both critical environmental dimensions for the real estate investor:
Biodiversity — BPS / Effinature
Biodiversity scoring and certification per asset. Feeds ESRS E4, SFDR, Taxonomy Objective 6.
Carbon — Efficarbone
Actual measurement of construction-site emissions (EN 15978, A4-A5). Feeds ESRS E1, BEGES scope 3, RE2020.
For an investor, this dual coverage means coherent ESG reporting, produced by the same independent third party, with auditable data on the two most structuring environmental standards of the CSRD (E1 climate and E4 biodiversity).
Integrating biodiversity and carbon into the investment decision
Biodiversity intervenes at three critical moments in the investment cycle. Each calls for a specific approach and type of assessment.
Before the decision: Risk & Selection
Assess the ecological resilience of assets under consideration for acquisition
Challenge: Identify assets exposed to high biodiversity risks before committing capital.
Key questions: Is the site located in a sensitive zone? Is the surrounding natural capital degraded? Are there specific regulatory obligations (Natura 2000, wetlands)? What is the project's ecological resilience potential?
IRICE approach: Biodiversity resilience assessment, mapping critical ecosystem services, external risk sources and the project's ability to maintain its value under different ecological and regulatory scenarios.
During the decision: Allocation & Compliance
Validate compliance and optimise capital allocation
Challenge: Ensure the project meets regulatory requirements (DNSH, SFDR, CSRD, green taxonomy) and fund criteria, while optimising the biodiversity strategy.
Key questions: Does the project benefit from relevant conservation measures? Are they appropriately sized and lasting? How do they articulate with regulatory obligations? What is the portfolio's risk/impact profile after this new asset?
IRICE approach: Compliance certification against the applicable regulatory framework, assessment of the quality and durability of mitigation measures, net impact scoring (NNL or BNG as per standards).
After the decision: Value & Resilience
Document long-term performance and protect value
Challenge: Ensure that the biodiversity performance promised at the decision stage is achieved, documented and maintained throughout the holding period.
Key questions: Are mitigation measures properly deployed? Is biodiversity evolving as expected? Are there new regulatory risks? What is the value trajectory?
IRICE approach: Periodic follow-up audits, documentation of condition changes, risk assessment updates, actual vs. promised impact reporting.
