We do not have data in the MSI on the impact of BCI cotton as finished material, we do have data on the reduced chemical impacts associated with BCI farming practices, which means that BCI can be selected as a chemistry certification for the raw material process of cotton.
The reason BCI is not featured in the MSI database as raw material as option, is because there is no publicly available LCA-data on BCI cotton. We are collaborating with BCI to feature data in the MSI once available.
If you want to reflect the reduced chemistry impact of BCI practices, you can select "conventional cotton" and use the BCI chemistry certification for the raw material process.
