VIETNAM OPPORTUNITIES / CATEGORY INTELLIGENCE / TRACEABILITY05A green claim needs a chain of custody.
A green claim needs a chain of custody.
Comparable evidence creates access.
A practical framework for material origin, recycled content, emissions, environmental declarations and project-level traceability.
Request a traceability brief
Sustainability becomes procurement evidence when the claim, product boundary, method, source and delivered batch remain connected.
METHOD
State product and lifecycle scope.
TRACE
Connect evidence to origin.
DELIVERY
Keep the approved product identifiable.
What changes.
What to do next.
01CLAIM CONTROL
Write claims that can be checked.
Separate recycled content, renewable input, emissions, energy, carbon and responsible sourcing. Each claim needs a defined unit and product boundary.
- OPPORTUNITY
- Clear comparison in premium and institutional procurement.
- PRIMARY RISK
- Broad green language that cannot survive technical review.
02EVIDENCE
Match the document to the claim.
Use current declarations, certificates, laboratory data, supplier records and calculation methods with visible issuer, date, scope and limitations.
- OPPORTUNITY
- Manufacturers with disciplined source documentation.
- PRIMARY RISK
- A certificate for a company or factory presented as product proof.
03TRACEABILITY
Connect source, production and shipment.
Product codes, bill of materials, suppliers, batches, invoices and delivery records should allow the approved material to be identified through the transaction.
- OPPORTUNITY
- Transparent supply chains as a buyer confidence asset.
- PRIMARY RISK
- Evidence that cannot be linked to the delivered product.
04PROJECT USE
Convert evidence into a submittal.
Present concise English documentation, comparison fields, renewal dates, contact ownership and change-control rules for substitutions.
- OPPORTUNITY
- Faster review by sustainability and specification teams.
- PRIMARY RISK
- Strong source evidence hidden in an unusable document package.
