1. An internal committee remains dependent on the designer of the reference framework

An internal committee, even one composed of experts, is dependent on:

• of the organization that created it,
• rules that he interprets,
• internal methodological guidelines,
• changes decided by the designer
• intellectual stimulation of the network,
• consolidated internal practices.

Institutional rule:

A committee created by the designer remains under the influence of the designer.

This is incompatible with the neutrality required by ISO standards 17065 and 17020.

2. The designer necessarily influences internal decisions

If the organism:

• writes the method,
• animates the network,
• trains the actors,
• clarifies the interpretations
• adjust the rules,
• validates the changes,

then the internal committee:

• relies on its guidelines,
• applies his doctrine,
• statue according to its criteria
• interprets according to its guidelines.

Result :

The decision depends on the structure that designed the method.

3. Decision-making independence requires organizational distance.

The requirements of impartiality necessitate a strict separation:

• The designer does not process the files.
• The guide does not take notes.
• The evaluator does not decide.
• The decision does not belong to the network.
• Governance is not internal to the system.

An impartial decision cannot come “from within”.

It must come from a separate, documented, audited body that is external to the influences of the network.

4. An internal committee is not a third party

For a decision to be institutionally recognized, it must be made by:

• an independent entity,
• an impartial structure,
• an instance with no functional link to the design.
• external or clearly separate governance
• an organization accreditable under the European framework.

An internal committee does not meet any of these conditions:

• He is not independent.
• He is not accreditable.
• It is not audited by a national accreditation body.
• He is part of the system that he validates.

Clear conclusion:

An internal committee is not an impartial third party.

5. The internal committee creates a systemic risk for public and financial actors

For a DREAL (Regional Directorate for the Environment, Planning and Housing), a local authority, an investor, a property company or a financial institution:

Using an internal decision poses three risks:

5.1 Risk of influenced decision

Validation depends on the organization promoting the method.

5.2 Risk of lack of enforceability

An internal decision cannot be verified by an independent body.

5.3 Risk of ESG/CSRD/Taxonomy incompatibility

Without an impartial third party, the data is not acceptable in regulatory reporting.

6. The independent model: separate decision, demonstrable impartiality

Institutional governance is based on:

1. Design

documented reference framework, separate from the evaluation.

2. Support

Dedicated mentors, never evaluators.

3. Assessment

Impartial evaluators, trained in procedure, not doctrine.

4. Decision

a separate, independent instance, free from the influences of the network.

5. Auditability

a certifiable, traceable process that complies with ISO standards.

This is the architecture followed by an accreditable body like IRICE.

Conclusion

Entrusting the final decision to an internal committee does not guarantee independence. Even if composed of experts, a committee led, facilitated, or interpreted by the method's designer remains structurally dependent on him.

Only a decision taken by a separate, impartial body organized according to international standards can ensure the institutional reliability of an environmental assessment.
