Build a claim around the evidence it actually supports

Research question

Environmental wording should identify the subject, condition and evidence that make the claim understandable to the reader.

A worked project scenario

A supplier offers a paper-based graphic described as fully recyclable. The buyer’s finished display also includes fittings and will be collected through a local contractor.

Method to use

Write the claim as a specific statement about the identified construction and receiving conditions. Attach the relevant source, test scope and limitations. Distinguish measurable recycled content, potential recyclability and achieved recovery. Have a reviewer trace each claim to the actual product and project record.

Limits of the conclusion

Leaf does not provide legal sign-off. An unqualified whole-product claim needs evidence for the whole product and its realistic use conditions.

Questions for the actual application

• Which exact source, unit and version support the decision?
• Which project quantities are measured, and which remain assumptions?
• What could change the result after installation or recovery?
