Asking a supplier “Are you sustainable?” does not produce a comparable answer. To use environmental information in procurement, specify the product, period and measurement involved. Digital tools can help collect the information, but its meaning and reliability still need review.
Make the questions category-specific
Recycled content may matter for packaging, energy use for equipment and the calculation method for transport services. Choose a small number of decision-relevant fields rather than sending the same long questionnaire to every supplier. State whether the expected answer is a number, supporting document or explanation.
ISO 20400 provides guidance on integrating sustainability into procurement. ISO 20400:2017 — Sustainable Procurement: Guidance A practical starting point is to distinguish a general company statement from information about the specific product. A supplier's environmental policy is not a substitute for measured product-level evidence.
Ask about units and boundaries in carbon data
The GHG Protocol Scope 3 guidance describes different calculation methods for purchased goods and services. GHG Protocol — Technical Guidance for Calculating Scope 3 Emissions Product-specific information and an estimate derived from expenditure should not be treated as equally precise. Ranking numbers without knowing their method, period and source can be misleading.
For example, a value per product cannot be compared directly with a value per kilogram. Ask whether packaging or transport is included in the stated boundary. Missing information should remain an unresolved field rather than being displayed as zero impact. Document any conversion or assumption used to make the figures comparable.
Collecting a document is not verifying it
An uploaded file does not prove that its contents are current or applicable to the item being purchased. Assign someone to review its scope and date. AI summaries of lengthy documents can assist preparation, but the source page supporting an important claim should remain accessible.
Do not change the evaluation criteria after offers arrive. Explain which information is mandatory and which may influence preference beforehand. This makes the environmental questions an understandable part of the purchase instead of an unclear scoring exercise.
Collecting information in Tenflex
Tenflex's auction and line-item questions can provide common response fields for non-price criteria. Company-specific supplier registration fields and requested attachments can also help collect initial information. These capabilities do not imply automatic carbon calculation or sustainability certification.
Start with three well-defined questions in one category. Review how many answers can genuinely be compared, then improve the wording for the next purchase. A small, usable dataset with clear evidence is more valuable than a large document archive that nobody uses in the decision.
