The European Union, through the Ecodesign for Sustainable Products Regulation and Regulation (EU) 2024/1781, with the Digital Product Passport regulation EU 2023/1542[1].
A rule that says regulated products need a digital passport to be sold in the EU market.
The passport is a set of digital credentials. The EU requires them to use W3C Verifiable Credentials. The same standard is used for CBAM, the EU's carbon border adjustment mechanism. The two share technical building blocks. The record does not establish that they are currently connected or integrated. The passport can carry a product's technical performance, the materials and their origins, repair activities, recycling capabilities, and lifecycle environmental impacts. It is shared and published as permissioned disclosures tied to identifiers and a QR or data carrier. The EU runs a Digital Product Passport Registry.
It shows how market access is tied to a digital credential system, and how the same technical standard can serve both product rules and border carbon rules.
