Name the sourcing question
Record the exact input, variant, supplier, source document, period and statement being considered. Identify whether the evidence concerns a material, a transaction, a site or another defined subject. Keep issuer terms and applicable wording visible. A responsible-sourcing statement should not expand across unsupported components or unrelated services.
Check applicability before wording
Review document validity, scope, relevant identifiers and the proposed claim subject. Ask the actual responsible source about gaps or contradictions. A scheme explanation is useful learning, but it does not independently verify the supplied order or confer mark-use permission. Preserve the distinction between documented, reviewed and independently assured information.
Ask lifecycle questions separately
If the buyer wants a broader environmental comparison, define equivalent service and appropriate boundaries for materials, manufacture, use, replacements, logistics and end of use. Sourcing evidence may inform that work, but it is not the same as a complete lifecycle result or a guaranteed reduction in every impact category.
Fictional claim narrowing
A display proposal includes sourced timber and several other constituents. Its draft says the whole installation is environmentally superior. The reviewer narrows the wording to the supported timber input and asks for service-aligned comparison evidence before any broader statement. Useful sourcing information remains available without being turned into an overall ranking.
Keep a correction-ready register
Store exact wording, evidence versions, responsible review and next check trigger. Recheck after supplier or component substitutions and correct current statements where scope changes. The claim register supports a defensible handover; it does not replace issuer verification, formal assurance or real project evidence. Historical applicability and current wording should remain distinguishable.
- Define the sourcing subject.
- Check current evidence and permissions.
- Separate broader lifecycle conclusions.
