Measurement Before Claims.

Three open-source indices that convert EU regulatory requirements into verifiable product-level data.

ORCID iD 0009-0001-3423-9402

The EU Ecodesign Regulation (ESPR) requires brands to certify durability, repairability, and recyclability — but provides no standardized calculation method. These three indices fill that gap, developed by Stefano Cipriani Studio and published under CC BY-NC-ND 4.0.

They are not theoretical. They are already integrated into the Reeco® platform and have been submitted to JRC for scientific validation.

Durability Index (V1.02)

What it measures: How long a garment will last — expressed as a class from A to E — based on 9 ISO-standardized textile tests.

Test battery includes: ISO 12945-2 (pilling) · ISO 13934-1 (tensile strength) · ISO 105-C06 (color fastness to washing) · abrasion resistance · washing stability

Why it matters: ESPR Article 5 requires minimum physical durability standards. The Durability Index provides a quantifiable, traceable score for DPP declarations and marketing claims.

Application: Any brand needing to certify garment durability for ESPR compliance, DPP data fields, or consumer labeling.

Repairability Index (V3.1)

What it measures: How easily a garment can be repaired during its use phase — scored 0 to 100, classified A to E.

Structure:

  • Block A (40%): Availability of replacement parts — fabric patches, buttons, zippers, thread
  • Block B (60%): Design for repair — accessible seams, modular components, standard stitching
  • Gate Rule: If essential replacement parts are unavailable, the score is capped regardless of design quality

Why it matters: The EU Right to Repair directive is entering force. Brands must demonstrate repair-oriented design. The RI provides a structured, standardized scoring method.

Application: Circular product design, ESPR compliance, repair-as-a-service, DPP data fields.

Waste Index (V1.0)

What it measures: The quantity of waste generated across a garment's lifecycle — expressed as a KPI for LCA, CSRD reporting, and CSDDD declarations.

Why it matters: Brands subject to CSRD must report environmental impact with verified data. The Waste Index provides a standardized calculation method that can be audited and integrated into sustainability reports.

Application: Supply chain ESG reporting, CSRD compliance, LCA input data, investor sustainability disclosures.
