How to read sustainability claims without getting lost

Strong sustainability research starts by separating the claim from the proof. A brand statement can be useful, but it is not the same as public documentation, certification, reviewed documents, or third-party audit evidence.

Sustainable Units scores are editorial assessments based on available information unless verified. The goal is to make comparison easier while keeping uncertainty visible.

For any important purchasing or partnership decision, use the directory as a starting point and request current documentation directly from the brand or service provider.
