The words, in plain language.

One paragraph each. If a word appears in a guide or on a regulation page, its definition is here.

Digital Product Passport (DPP)
The set of data a product must carry on the European market, attached to a unique identifier and reachable from a code printed on the product itself.
ESPR
Regulation (EU) 2024/1781. It is the framework that creates the passport and sets out which requirements the Commission may impose on a product group.
Delegated act
The later act that sets a product group's actual requirements: which fields are mandatory, which thresholds apply, and by when. For textiles it has not been adopted yet.
Data carrier
The physical object that leads to the passport. In fashion, in practice, a QR printed on the label.
Tier
The distance from a company to the finished garment. Tier 1 makes it, tier 2 supplies tier 1, and so on down to the fibre.
Provenance
The record of which document a value came from, on what date, and who confirmed it. Without it, a value is an assertion.
LCA
Life-cycle assessment: the method that estimates a product's impacts across all its stages, from raw material to end of life.
PEF
The European Product Environmental Footprint method, across sixteen impact categories. It is the base the French environmental cost is built on.
Environmental cost
The French scheme: a single number, in impact points, displayed with no colours and no classes. The lower the better.
SNET
The Italian textile eco-score proposed by a bill, graded A to E. The text defines no method, so no class is computable today.
GS1 Digital Link
The scheme the address inside the printed code is built on. It lets the same code always point at the current version of the passport.
EPR
Extended producer responsibility: the duty to contribute to collecting and treating products at end of life. In Italy and France it already covers textiles.
DPP Registry
The European Commission's registry. It holds identifiers and metadata, not passports: those stay with the operator or with its service provider.
Measured share
The part of an indicator computed from supplier documents rather than from public averages. It grows as the documents arrive.
