Under the E U Ecodesign for Sustainable Products Regulation (ESPR), a Digital Product Passport contains structured product-level data that will be defined through delegated acts, based on the framework set out in Annex I and Annex III of the regulation and further developed through the European Commission and JRC milestones. In practice, a DPP includes both mandatory and additional voluntary information. Mandatory data is defined at product-category level and typically covers product identification, information on the manufacturer or economic operator, material composition and substances of concern, environmental performance, compliance documentation, and instructions for use, repair, and end-of-life handling. These requirements must be provided in a structured, machine-readable, and interoperable format. Beyond this, a DPP can include additional information depending on the product, regulatory developments, and use cases. This may cover aspects such as durability, repairability, recyclability, recycled content, environmental impact, or supply chain data. The scope of this additional information is not fixed and evolves over time as delegated acts are adopted (expected for Q3 2027) and requirements become more detailed (Digital Product Passport Registry confirmed for July 2026). Overall, the Digital Product Passport is designed as a dynamic system, where core mandatory data is defined by regulation, while additional information can expand to support transparency, circularity and added business value across the product lifecycle.
