Product Recalls and the Digital Product Passport
Recall cost is proportional to scope. Traceability is the only way to narrow it.
Verification
DPP Verification, Trust and Digital Signatures
A passport is only valuable if it is trustworthy. We explain the digital-signature and versioning mechanisms that prove data was not tampered with.
Verification
Fighting Counterfeits With a Digital Product Passport
A QR can be copied. But a copied identity that cannot be verified is what makes counterfeiting visible.
Security
Audit Trails and Versioning in a DPP
A system that cannot answer "what did you declare last year?" is incomplete for audit purposes.

DPP Access Rights: Who Sees What?
The most misunderstood aspect of a passport. Tiered access is what makes transparency compatible with trade secrets.
Verification
eIDAS, E-Seals and Signing a DPP
Companies do not sign — they seal. In EU law, the right instrument for a passport is an electronic seal.
Standards
What Is UNTP (the UN Transparency Protocol)?
The DPP's global, decentralised cousin — and why it matters in cross-border trade.
Standards
Restricted Data Tiers and Authorised Access (EN 18239)
Not every piece of data must be public. Restricted tiers and authorised access strike the balance between transparency and trade secrets.
Verification
DIDs: Decentralized Identifiers in a DPP
An identity verifiable without a central registration authority. Where it genuinely helps in a passport.
Verification
Verifiable Credentials for the Digital Product Passport
The technology that closes the gap between a declaration and proof. Signed supplier data makes audits far easier.
Standards
EN 18246: Data Authentication and Integrity
Who guarantees the data in a passport is genuine? This standard defines the signature and integrity layer.
GDPR
GDPR/KVKK and DPP Data Management
The passport is public; but what about trade secrets and personal data? We explain how to keep the DPP compliant with GDPR/KVKK.
Green Claims
The Green Claims Directive and Greenwashing
Calling something "eco-friendly" is no longer free. An unevidenced claim is becoming a visible legal risk.
Supply Chain
Supply-Chain Traceability and the DPP
The hardest part of the passport is often outside your own factory: data from your suppliers. We explain how to build traceability.
Battery
Battery Passport Annex XIII Data Fields
Around 90 mandatory attributes across three access tiers. Which field sits where, and which apply when.
Supply Chain
DPP Data Quality Management
A wrong passport is riskier than an incomplete one. How to build quality control into the process rather than bolting it on.
Circularity
How to Prove Recycled Content
Saying "30% recycled" is easy; proving it is not. Chain-of-custody models and what evidence belongs in the passport.
Life Cycle Assessment
What Is an EPD? Environmental Product Declarations and the DPP
A verified, rules-based and comparable environmental statement. Why construction and B2B tenders keep asking for one.
Life Cycle Assessment
ISO 14040, 14044 and 14067 Compared
Which standard when? The scope of each, how they relate, and what they mean for verification.
Standards
The EN 18219 / 18221 / 18222 Standards Family
The DPP rests not on a single standard but on a complementary family: data model, access, unique identity and interoperability.
