SAYE operates with the environment at the forefront of its mind, and from the get-go they ensured the means of production were both sustainable and ethical. Opting to create their collections in Portugal due to the artisanal craft and fair working conditions, SAYE operates a 100% transparent production line that promotes sustainable fashion with a reduced carbon footprint. The brand sources all of its materials in Europe and cares a lot about the planet and the negative effect humans are having on it. As well as using organic and recycled materials where possible, SAYE collaborates with the NGO 'We Forest', where for every pair of trainers sold 2 trees are planted to help tackle the environmental crisis. So far, they've planted over 130,000 trees!
