What Material Data Is Needed for an Activewear Sustainability Report?

Reports need material composition, quantities, sources, processing boundaries, and evidence behind claimed attributes.

Traceability needs consistent identifiers across suppliers, materials, processes, and finished orders. Retain the source documents and record changes or unresolved gaps; a supplier's assurance is easier to evaluate when the brand can follow the claimed attribute through the relevant stages rather than relying on an isolated logo. Use consistent definitions and reporting periods.
