The project lays the groundwork for a European digital product passport by expanding legal information requirements, developed in collaboration with stakeholders using textiles and energy-related products as examples. It explores how key product data can be digitally tracked, combined, and made accessible across the life cycle. Existing tracking approaches and information flows are identified and assessed using a front-end demonstrator resembling a digital product passport. Legal recommendations for action are included. The report is targeted at all stakeholders in the DPP environment.
