Cotton Rankings

The data used for these rankings was collected between March and June 2025 from public resources. Occasionally, due to insufficient disclosure, estimates have been made based on what has been published.

Some key points for reading these rankings:

Ranking 1: covers the percentage of certified cotton out of a brand’s total cotton supply.
For this ranking we consider as certified the following certifications: BCI, CmiA, GOTS, OCS, Fairtrade, US CTP, REEL, MyBMP, ABR, Cotton Leads. For certified recycled cotton, we considered RCS and GRS.

Where the data is available, a breakdown of from where the certified cotton has been sourced by each brand has been provided.

Note: Some data has been collected at the group level. Where this is the case, the group level is also indicated in the text.

Ranking 2: charts the amount of cotton used by each of the brands/groups assessed. Where total cotton disclosures have been unavailable, this has been estimated, where possible.

Ranking 3: compares the percentage of cotton vs the percentage of synthetic fibres purchased by a brand/group. 

As Solidaridad takes the stance that cotton has a greater potential for sustainability, brands/groups with a higher cotton percentage are rated higher on this chart.

Other materials, which can also include other natural fibres such as wool, are also indicated.

Any updates made since June then have not been integrated. We invite brands to contact us directly with any updates they would like to signal on the Sustainable Cotton Hub. You can reach Tamar Hoek at tamar.hoek@solidaridadnetwork.org
