The Ellen MacArthur Foundation (EMF) is a charity whose core focus is on accelerating the transition to a circular economy. Founded in 2010, the EMF works across six key areas: learning; business; institutions, governments and cities; insight and analysis; systemic initiatives; and communications.(1) The EMF’s Make Fashion Circular initiative aims to encourage collaboration and innovation, both seen as key priorities in the industry’s transition to a circular model. The initiative has identified three ambitions for the future: products made from safe, renewable materials; new business models to increase use; and old products turned into new ones. The core outputs of the Make Fashion Circular initiative include the influential report A New Textiles Economy: Redesigning Fashion’s Future,(3) a much quoted source on fashion’s environmental impact. In 2019, the initiative also launched the Jeans Redesign project that sets new product requirements for circular denim, including standards on durability, material health, recyclability and traceability. Circular jeans that meet these standards are expected to reach the market in August 2020.(4)
