Sustainability language is everywhere, but useful specification depends on clear boundaries and verifiable evidence.
Define what the claim measures
Recycled content, renewable inputs, low emissions and local manufacture address different impacts. Avoid treating one attribute as proof of overall sustainability.
Request product-level documentation
Prioritise environmental product declarations, health product declarations, chain-of-custody certificates and current laboratory reports.
Consider the full service life
Durability, repair, cleaning requirements, disassembly and future reuse can matter as much as initial manufacturing impact.
Write measurable requirements
Translate broad goals into project specifications that state percentages, standards, testing methods and acceptable evidence.
