Responsible-supply statements are most useful when they identify their subject, boundary, date and method. An assurance decision for one site is different from a product’s traceability record, a chain-of-custody claim or a calculation of recycled content.
The Copper Mark organisation evolved into Veramark Assurance on 15 October 2026. Its current assurance process describes independent site-level assessment. Rio Tinto’s START page provides a different example: product information and traceability associated with specified materials. These mechanisms have their own scope; a generic planning checklist does not replace either.
Four practical questions
What is covered? Name the site, batch, product, reporting period and activity. Avoid transferring a statement about one operation to an entire corporation or a different product.
How was it established? Identify primary measurements, estimates, allocation rules, secondary data and any independent assessment. An intensity calculation requires a denominator and a defined boundary before comparisons are meaningful.
Where does recycling enter? Distinguish new manufacturing scrap from end-of-life scrap. Collection and recovery losses affect usable supply. A material can be recyclable without a specific product containing a verified recycled fraction.
What changed? A new source, process or ownership arrangement may require updated evidence. Keep the underlying record and its date, rather than preserving only a marketing badge.

Our circularity guide and project-readiness questions help teams request the relevant documents. They do not verify emissions, chain of custody, recycled content or conformance with an assurance standard. Product procurement still needs the applicable contract, specification and evidence review.
