This report defines ‘textiles’ as all products that contain knit or woven textile components, primarily composed of apparel and footwear, but also including home textiles, technical, medical and automotive textiles, etc. The main report is intended as a general summary of challenges, opportunities, solutions and next steps for a sustainable and circular textile value chain. It outlines nine building blocks that specifically explore the cross-stakeholder opportunities for change, and how collaboration can be facilitated to deliver them, highlighting examples of actions for those stakeholders that are most crucial or influential for each building block. The report provides examples of initiatives, commercial companies, products and other work that serve as an illustration of tackling different sustainability aspects, but should not be read as an endorsement by UNEP or an “end state” example of circularity in the textile value chain.
