We use certifications where it is feasible to map the fact that the brands holds a certification to the specific issues in the fashion supply chain that impact on people, the planet and animals. B Corp certification is available for companies that score 80 points or more out of an available 200, across 6 different areas some of which are not related to the impacts of fashion that we look at.
It is not possible to work out just from the B Corp certification whether the brand is addressing a specific issue. In addition the brand is in most cases separately communicating how it addresses each of the issues we look at and so there is a risk of double counting.
We strongly support the B Corp movement but have not found a practicable way (nor a need) to include B Corp certification in our scoring system.
