Swiss company bluesign® has developed a methodology to screen fabrics into a positive or blue list (no hazardous chemicals contained), a grey list (contains potentially hazardous substances but not alternatives are available on the market) and a black list (contains hazardous chemicals and should not be used).
During an extensive audit of the fabric production facilities, issues of energy and water efficiency as well as worker health and safety are considered as well. Finally, once the factory and the fabric adhere to the bluesign® standards, the fabric will get bluesign® certification.
PUMA has been using bluesign® approved fabrics to a large extent over the recent years. In a move to join forces on the elimination of hazardous substances and to further strengthen the use of bluesign's expertise and network, PUMA has become an official bluesign® system partner in 2014.
