The fashion and textile industry is characterised by long and fragmented supply chains, where information about materials, processes and treatments is spread across many actors and is not always recorded in a consistent way. Because of this, tracing products, assessing environmental impacts and meeting new sustainability requirements is often difficult. Recent European regulations, in particular the Ecodesign for Sustainable Products Regulation (ESPR), introduce the Digital Product Passport (DPP) to improve product transparency. However, although the regulatory framework is being defined, there is still little clarity on how the required information should actually be organised and managed in practice within the textile sector.
