The SANE Approved Material List has been elaborated by sustainability experts throughout 5 years of research on the measured environmental impact of fibers and materials most commonly used in the fashion industry. It takes into account prevailing benchmarks1 and scientific studies2, industry recognition, availability, and scalability of each material as well as credible certifications and laboratory testing when relevant.

Our SANE Approved Material List is designed to evolve together with the market sustainability standards and to be submitted to multi-stakeholders periodic reviews.
