The Textile Exchange organisation owns the Responsible Wool Standard and focuses on sheep welfare and grazing land. RWS certifies all actors in the wool value chain, from wool farmers to yarn and textile producers and clothing brands. The certification for wool farms includes criteria for animal welfare and land management. Other players in the value chain are certified according to different criteria with the aim of tracking raw materials through all stages and ensuring the product’s content integrity.
