The US Cotton Trust Protocol, a voluntary farm-level sustainability programme, has reached milestone of welcoming more than 300 brand, retailer, mill and manufacturer members since it opened enrolment six months ago. This includes Gap and its purpose-led lifestyle brands Old Navy, Gap, Banana Republic and Athleta as well as UK retailers Next and Byford. The Trust Protocol also has welcomed the first US mills, the first members in Latin America, and Advance Denim, one of China’s top three denim manufacturers. “Sustainability and transparency are becoming more important in the fashion industry,” Dr Gary Adams, president of the US Cotton Trust Protocol, said in a press release. “Consumers expect and are calling for reduction in companies’ environmental footprint and the Trust Protocol will provide the data that enables them to tell their sustainability story.” The Trust Protocol is a system for more responsibly grown cotton that has committed to six areas of sustainability in line with the UN Sustainability Development Goals. It underpins and verifies sustainability progress through sophisticated data collection and independent third-party verification, enabling members to better track the cotton entering their supply chain. Members also will have access to aggregate year-over-year data on water use, greenhouse gas emissions, energy use, soil carbon and land use efficiency. “The Trust Protocol is a complement to other sustainability initiatives and was designed to fit the unique growing environment in the United States,” Adams said. “By joining, these more than 300 members will have the critical assurances needed to verify that the cotton fibre element of their supply chain is more sustainably grown.” The Trust Protocol is included on the Textile Exchange’s list of 36 preferred fibres and materials that more than 170 participating brands and retailers can select from as part of Textile Exchange’s Material Change Index programme. The Trust Protocol also is working to align with existing standards in the cotton industry and is part of the Forum for the Future Cotton 2040 and the CottonUp guide.
