The YESS Standard and YESS Workbook provide the foundation for the YESS initiative. They are a specific, practical framework to assess the operations and sourcing procedures of cotton yarn spinning mills. They are a guide for spinners to avoid purchasing cotton that has a high production risk of forced labor.

These documents were developed with input from brands, spinning mills, industry associations, and labor experts. To create the YESS Standard, 16 spinning mills were visited, more than 200 comments were addressed during the public consultation process, and five trainings were piloted explaining the YESS approach.
