The textile and apparel industry has become increasingly eco-conscious, as companies have come under scrutiny for the negative impact their operations have on the environment and on society. Textile Exchange -- an organisation which foresees a sustainable future for the textile and apparel industry -- hosts an annual conference which provides an opportunity for brands, retailers, manufacturers, consumers, media and pressure groups to learn about the key sustainability issues in the industry. The most recent such event was held in Barcelona, Spain, during September 2011. This report offers vital insight and analysis into strategies for sustainability in the global apparel industry which were presented at the conference. It looks at the ways companies are trying to mitigate their harmful impacts on society and the environment, and how collaboration, transparency and integrity are helping them to do this. There is also an overview of the main certification systems for sustainable textiles and apparel as well as the latest innovations in apparel sustainability. In addition, the report provides insight into work by a number of companies and organisations in the area of sustainability, including Adidas, Anti Fraud Initiative (AFI), Arkema, bioRe, bluesign technologies, Chetna, Clean Clothes Campaign (CCC), Control Union Certifications, Egedeniz Textile, Greenpeace, GreenXchange, Huntsman Textile Effects, Ingeo, Institute for Marketecology (IMO), International Working Group (IWG), Lenzing, MADE-BY, Nike, Oeko-Tex, Orta Anadolu, Outdoor Industry Association (OIA), Remei, Sanko Tekstil, Sofila, Solidaridad, Sorona, Sustainable Apparel Coalition, Unitika Fibers and Yeh Group.
