The EU Just Published Its DPP Data Methodology: What Fashion Brands Need to Know
TL;DR
The European Commission's Joint Research Centre has published the methodology that will define what data goes into Digital Product Passports. Textiles are in the 2027 wave. Here is what it means for fashion brands.
The European Commission's Joint Research Centre has published the first official methodology for defining what data goes into Digital Product Passports under the Ecodesign for Sustainable Products Regulation (ESPR). The report, Methodology for defining data requirements for the Digital Product Passport under the ESPR framework, was published in 2026 and sets out a structured, four-step process for determining what information each product group's DPP must contain.
For fashion brands, this document matters because it is the methodology that will shape the textile delegated act. Textiles are in the 2027 wave of DPP implementation. The preparatory work is already underway. And the methodology published here is what the study teams will use to decide which data points become mandatory, which become voluntary and which get deferred.
What the Document Actually Is
This is not a regulation. It is not a delegated act. It is the methodology that the European Commission will use to develop delegated acts for each product group, including textiles.
The report describes a four-step process (Steps A through D) that preparatory study teams must follow when defining DPP content for a given product group. The steps move from defining scope and context, through identifying use cases and data needs, to designing the data specification and validating it with stakeholders.
The methodology is designed to sit within the existing Methodology for Ecodesign of Energy-related Products (MEErP), which has been used for over 30 preparatory studies. The DPP data specification methodology extends this framework to cover the broader sustainability and circularity requirements introduced by the ESPR.
Why It Matters for Fashion
The first ESPR Working Plan, published in April 2025, identified textiles as a priority product group with an indicative timeline of 2027 for the delegated act. Iron and steel are first (2026), with textiles, tyres and aluminium following in the next wave.
The textile preparatory study is already active. The methodology published in this report is what the study team will follow to determine which data fashion brands will need to provide in their DPPs. The product scope table in the report lists exactly which garment categories are in scope: t-shirts, shirts, sweaters, jackets, pants, dresses, leggings, underwear, swimwear and apparel accessories including hats, scarves, belts and gloves.
What is excluded is equally telling: smart textiles, electronic textiles, personal protective equipment (PPE) and medical device textiles are all out of scope.
Product-Level Environmental Data Is Central
The methodology makes clear that product-level environmental data is the foundation of the DPP. It explicitly references the Product Environmental Footprint (PEF) method, ISO 14040/14044 and the PEFCR for apparel and footwear as the methodological basis for calculating environmental impacts.
This is not about brand-level sustainability statements. It is about quantified, product-level data covering multiple impact categories. The report lists 16 PEF impact categories and identifies climate change and water use as consistently among the most relevant for apparel.
Data Prioritisation and Feasibility
One of the most practical aspects of the methodology is its approach to classifying data needs. The report introduces a six-category matrix (A through F) for prioritising data points based on perceived value, current industry practice, implementation effort and barriers.
Category A data points are high value, already widely collected by industry and have low implementation risk. These are the ones most likely to become mandatory in the first wave. Category D data points are lower value, not currently collected and have high feasibility barriers. These are candidates for deferral or voluntary status.
For brands, this classification matters because it signals which data requirements are most likely to arrive first and which may be phased in over time. Brands that are already collecting product-level environmental data are positioned to meet the baseline requirements without significant additional effort.
What This Means in Practice
The methodology is grounded in existing industry practices. It explicitly states that the DPP should build on what companies already collect rather than creating an entirely new data collection burden. It requires study teams to assess current data practices in the value chain and to align DPP requirements with what is already available where possible.
This is a pragmatic approach. But it also means that brands with no structured product-level data infrastructure are starting from a weaker position. The methodology's emphasis on feasibility and proportionality favours companies that have already invested in structured environmental data.
How ENVRT Approaches DPP Readiness
ENVRT LAB™ generates climate impact (CO₂e) and water scarcity impact at the product level, on a cradle-to-gate basis and aligned with ISO 14040 and PEFCR methodology. This is the same methodological foundation that the JRC report identifies as the basis for DPP environmental data.
The product-level data ENVRT produces maps directly to the data categories the methodology describes: environmental footprint, material composition, carbon footprint and water use. Brands working with ENVRT are building the data infrastructure that this methodology requires, using the methods it references.

Frequently asked questions
No. The methodology is the framework that preparatory study teams use to develop the delegated act. It defines how data requirements are identified, prioritised and specified. The delegated act is the legally binding regulation that will follow.
