Rising cotton prices have boosted demand for wood-based fabrics such as viscose, rayon and modal, which increasingly involves clearing forests and taking land used by indigenous people, according to Rainforest Action Network (RAN).
Ralph Lauren is the latest in a growing number of fashion companies to pledge to investigate its supply chain to determine if it is using products from the most destructive regions and stop using those sources by the end of 2017, said RAN.
RAN's "Out of Fashion" campaign to publicize the impacts of forest-based fabrics has called on major U.S. brands to adopt stringent, sustainable sourcing systems.
Ralph Lauren said it will publish its new sourcing guidelines as part of a broader initiative to ensure its raw materials are free of human and land rights abuses and are environmentally sustainable.
