Understanding CO₂e requests — Case #1
In most situations, a “supplier carbon attestation” is not a legal obligation and not an audit. It is an operational request from procurement teams: obtain a simple, consistent and reusable CO₂e indicator for ESG screening, supplier onboarding and tenders.
Organizations facing transparency obligations (or market expectations) need environmental information across their value chain. In practice, this becomes supplier questionnaires, responsible procurement criteria, and simple “proof” documents to support internal files.
A supplier CO₂e attestation is generally acceptable when used for screening, onboarding or internal comparison (procurement decision). It is not acceptable when used as a substitute for regulatory reporting or certification.
If a contracting party requires an audit or a specific standard, the right move is to clarify the expected scope (screening vs audited reporting) before producing any document.
Buyers prefer a document that looks like operational evidence: dated, identifiable, methodologically explicit, and easy to archive. The value is not maximum scientific precision; it is consistency and reusability.
A document with these elements typically satisfies procurement screening and internal file requirements, without claiming certification.
Legal safety and credibility rely on one thing: state clearly what the document is and what it is not. The goal is to avoid third parties interpreting the attestation as an audit or regulatory compliance.
To scope an over-ambitious request (audit, compliance), the most effective answer is: “We can provide a standardized, indicative estimate for procurement screening. If you require an audit or a specific standard, please specify the expected framework and scope.”
The problem with supplier CO₂e requests is not missing data. It is the lack of a simple, stable, reusable format. Standardization reduces:
Yes, contractually a buyer can impose requirements. In practice, most requests target a simple indicator for screening, especially early in the process. If an audited requirement is stated, ask for the exact standard and scope.
No. CSRD/ESRS applies to companies under the reporting obligation. Supplier requests are most often value-chain data collection. An indicative attestation is relevant only as an informational document (screening), not as regulatory reporting.
Clarify whether the buyer wants an indicative screening indicator or audited publication. If the request is for screening, provide a standardized document stating method and limitations. If a full inventory is required, an indicative attestation is not the right tool.
If a customer asks for a “supplier carbon attestation”, the goal is usually a procurement screening indicator. Certif-Scope produces an indicative, structured, traceable and verifiable attestation.
