 Environmental certification - proof, accountability and public procurement after 2026

Environmental certification - proof, accountability and public procurement after 2026

Tuesday, January 20, 2026

A legitimate debate, often misframed. Representatives of the real estate sector, particularly developers, are now expressing a clear position: environmental certifications are costly, redundant with existing regulations, undervalued by end buyers, and compete with approaches considered more flexible or accessible. These observations reflect genuine economic concerns. However, they call for a crucial clarification: the debate is no longer about environmental intent, but about proof, liability, and legal enforceability.

Regulation and certification: two separate registers

Environmental regulations establish a mandatory minimum standard. They govern practices and impose obligations.
They do not produce independent proof.

Environmental certification is not intended to replace regulations. It aims to attest, by an independent third party, that a project complies with a given standard or achieves a demonstrated level of performance.

Adhering to a rule is not the same as demonstrating performance. This distinction becomes crucial when environmental commitments are formalized in contracts, communicated, or integrated into public policies.

Displayed cost and actual cost of risk

The unit cost of certifications is often highlighted. It is accurate from an accounting perspective, but incomplete from a legal standpoint.

He notably omits:

  • the risk of challenges to environmental claims,
  • the reclassification of communications as “sustainable”,
  • exposure to litigation related to greenwashing,
  • the weakening of contractual or CSR commitments,
  • the difficulty in demonstrating, a posteriori, the reality of the choices made.

In this context, environmental certification is less a cost than a tool for legal and financial security.

Directive (EU) 2024/825: a change in tolerance, not in nature

Directive (EU) 2024/825 requires that all environmental claims be based on verifiable, objective, and independent evidence. Its transposition into French law is scheduled for March 27, 2026.

Key point: the directive does not transform inconclusive actions into evidence. It reduces the legal tolerance for commitments that cannot be demonstrated.

What was not legally admissible before 2026 does not become so afterward. The directive does not create evidence; it requires that it exist.

Public procurement after August 22, 2026: from intention to enforceability

From August 22, 2026, all public procurement contracts must integrate at least one environmental consideration into:

  • the criteria for analyzing bids,
  • and/or the execution clauses.

This obligation does not concern the display. It concerns the ability to demonstrate, verify and enforce the commitments made.

Internal specifications, charters, and methods remain lawful and useful for structuring an intention. However, they have never constituted, and still do not constitute, a legal safeguard, due to the lack of independent evidence that can be used against a third party.

Labels, participatory approaches and methods: their real status

Confusion persists between:

  • private labels,
  • participatory approaches,
  • internal or sector-specific reference frameworks,
  • environmental communication tools,
  • prescriptive methods.

These devices fall under the category of:

  • voluntary membership,
  • pedagogy,
  • sector animation,
  • the structuring of intentions.

They have never constituted, either before or after Directive (EU) 2024/825, legally admissible evidence.

They can support a project. They cannot legally secure a decision.

Prescription and performance: a common confusion

Many alternative approaches rely on prescriptive elements: lists of good practices, imposed solutions, standard procedures, resource requirements.

The prescription describes what must be done. It does not demonstrate what is actually achieved.

A device can be very prescriptive and well-documented without necessarily producing independent proof of the level of performance achieved.

The statute of limitations is not proof.

Independent assessment tools: a separate registry not to be confused

It is important to distinguish between labels, participatory approaches or prescriptive mechanisms and independent assessment tools, designed as instruments for analysis and decision support.

These tools are not intended to produce legally admissible evidence.

They aim to:

  • to measure a performance level at a given moment,
  • to objectify discrepancies,
  • compare scenarios,
  • to inform design or programming choices.

They are neither about membership nor display. They constitute an analytical basis, often essential prior to a decision or certification.

In this logic, an independent assessment tool is not an alternative to certification, but a preparatory mechanism, enabling the structuring of a credible and measurable trajectory.

Accredited environmental certification: the register of evidence

An accredited environmental certification is based on:

  • a public and stable reference framework,
  • an evaluation carried out by an independent third party,
  • a strict separation between support and decision-making,
  • a clearly identified chain of responsibility.

Accredited certification is defined as certification issued by an organization evaluated according to international standards that guarantee independence, impartiality, and competence.

When the same actor defines the method, oversees the project, and validates the results, there is no independence. Therefore, there is no admissible evidence.

The end buyer: protected by construction

It is true that the end buyer often focuses on price. This does not mean that they are without protection.

Real estate law relies on safeguarding mechanisms, notably EMPCO, designed to protect the buyer against risks that he cannot assess alone.

These mechanisms do not guarantee environmental performance. However, they contribute to the overall legal security of the action, in which the credibility of environmental commitments plays an increasing role.

Accredited environmental certification is not intended to convince the buyer. It aims to secure the entire chain of responsibility, including for the buyer's benefit.

Freedom of action and responsibility for decisions

The aim is not to impose a single model or to dismiss useful initiatives. It is to clarify the roles and responsibilities:

  • Commitment is not proof
  • Prescription is not performance
  • Assessment is not certification
  • The method is not enforceability.

Freedom of initiative remains. Legal responsibility, however, is tied to proof.

Conclusion

The question is no longer whether environmental certifications are desirable. The question is who bears the legal risk when no independent evidence is produced.

Neither before nor after Directive (EU) 2024/825 have private labels, participatory approaches or prescriptive mechanisms constituted a legal bulwark.

In a context of stricter regulations, increased public procurement and greater demand for environmental credibility, accredited environmental certification is emerging as the legally operative register of proof, in conjunction with independent assessment tools used upstream to inform decisions.

Frequently Asked Questions

Are labels and participatory approaches useless?
No. They are useful for mobilizing, structuring, and supporting. They do not constitute legal proof.

Does Directive 2024/825 mandate certifications?
No. It imposes a requirement for independent proof. Accredited certification meets this requirement.

Are assessment or scoring tools disqualified?
No. They play an essential role in supporting upstream decision-making. They do not produce legally binding evidence.

Isn't a prescriptive approach more rigorous?
It may be demanding, but it remains an obligation of means. Performance must be demonstrated.

Were these measures sufficient before 2026?
No. They never constituted a legal safeguard. The directive simply reduces the tolerance for their use as evidence.

Why is independence central?
Because admissible evidence requires independent assessment and clearly identified responsibility.

Is the end buyer affected?
Yes, indirectly. The credibility of the commitments secures the entire purchasing process.

Does this article impose a single model?
No. It clarifies the levels of evidence and the associated responsibilities.
