Start with the legal frame
The Ecodesign for Sustainable Products Regulation creates a horizontal framework. It does not make one identical passport mandatory for every product today.
- Separate current duties from preparatory work
- Record the source and review date for every regulatory decision
Give the record a durable identity
A product model, batch or serialized item needs a stable identifier and a resolver that can survive a website redesign. The carrier is the access route; it is not the record itself.
- Use machine-readable JSON or JSON-LD alongside a human page
- Keep previous published versions immutable
Control what each audience sees
Manufacturers, repairers, market-surveillance authorities and consumers may need different fields. Apply access rules before rendering public HTML, JSON or a PDF.
- Keep supplier evidence private by default
- Show an understandable evidence status instead of a badge with no explanation
What a DPP does not prove
A passport is not automatically a sustainability score, a blockchain token, a certificate, proof of ownership or proof that a physical item is genuine. Those claims need their own evidence and workflow.
A sensible first implementation
Start with identifiers, materials, suppliers, evidence, care and publication governance. Make the record useful now while keeping future delegated-act fields versioned and reviewable.
