bluesign® is a certification system that evaluates the use of chemicals, materials, processes and also the finished textile products against five sustainability principles: resource efficiency (chemicals and raw materials, energy, water); consumer safety; air emissions; water emissions; and occupational health and safety. The term ‘bluesign® system partner’ then refers to any organization whose products meet these standards, from brands to manufacturers and chemical suppliers. The bluesign® certification requires that products consist of minimum 90% bluesign® textiles and 30% bluesign® accessories. Launched in Switzerland in 2000, the bluesign® certification is currently considered one of the most stringent worldwide, as it requires a holistic measuring of social and environmental performance, including elimination of all hazardous and polluting substances across the entire supply chain.
