A complete fashion Digital Product Passport requires three things: structured supplier traceability data, calculated environmental impact and a consumer-facing rendering layer accessed through a QR code. These are the three layers that the JRC's DPP data methodology implicitly requires.
Most platforms in the market today cover one or two of these layers. Few cover all three natively. This guide maps which platforms specialise where, why that matters for procurement and what the practical implications are for brands choosing between a single integrated platform and a stack of two or three.
The Three Layers of a Fashion DPP
Layer 1: Traceability. The structured supplier data layer. Country of origin for each significant stage, recognised certifications held, material composition at fibre level, supplier identity in restricted access tiers, chain of custody documentation. This is the foundation: without it, environmental calculations are forced onto industry averages and the DPP loses its product-level specificity.
Layer 2: LCA. The environmental calculation layer. ISO 14040 and 14044 methodology, PEFCR alignment for apparel and footwear, 16 PEF impact categories or a subset, AWARE water scarcity characterisation. This translates traceability data into impact figures the DPP needs to display.
Layer 3: Rendering. The consumer-facing layer. QR code access, structured presentation of the data fields the consumer is entitled to see under tier 1 of the role-based access model, brand-aligned design, scan analytics. This is what the consumer interacts with.
A brand needs all three to publish a credible DPP. The question for procurement is whether one platform delivers them or whether two or three must be combined.
How the Major Platforms Specialise
Each vendor's own product pages and partnership documentation make the specialisation clear.
Traceability-led platforms. Retraced, TrusTrace and (in a hybrid shape) Fairly Made are built primarily around supplier data structuring and supply chain transparency. They are strong on Layer 1. Retraced and TrusTrace partner for Layer 2; Fairly Made includes native LCA.
LCA-led platforms. Carbonfact is the clearest example. Built around ISO 14040 methodology, PwC-reviewed assessment, 50M+ product LCA database. Strong on Layer 2. Native traceability is not a core part of the platform; brands typically use a traceability platform alongside.
Infrastructure or orchestration platforms. Renoon positions itself as an operational DPP system connecting existing brand systems. It includes some LCA capability and some traceability capability, with a focus on integration depth across PLM, ERP and CRM rather than methodology depth in any single layer.
Marketing-led or rendering-led platforms. EON, Arianee, Avery Dennison and Tappr focus on the consumer-facing rendering layer. Strong on Layer 3 and on data carrier technology (NFC, blockchain authentication, brand-aligned consumer experiences). They typically source data from upstream platforms rather than collecting it natively.
Integrated platforms. ENVRT is built around all three layers as a single product. The LCA engine, traceability data layer and DPP rendering are designed to work together natively rather than via integration between separate components.
The category framework Carbonfact itself uses in its own buyer's comparison post describes four categories: marketing-led, traceability-led, LCA-led and layered DPP systems. The integrated category sits across these.
Why Platforms Partner Instead of Building
The LCA methodology layer is hard to build. ISO 14040 alignment, PEFCR adherence, multi-indicator characterisation, an emission factor database, methodology review and ongoing alignment with PEF updates each require specialist capability and years of investment. The most prominent independent LCA platform in fashion, Carbonfact, has public PwC review of its methodology and a stated 50M+ LCA database. Building that depth is genuinely difficult.
The result is that traceability-led platforms typically choose to integrate rather than build. Retraced's public partnership material describes integrations with LCA platforms including Carbonfact and Bcome. TrusTrace describes a partnership with Peftrust for LCA. These are honest decisions reflecting the cost of building methodology depth versus integrating with platforms that already have it.
The trade-off for brands is that integrated stacks introduce a second vendor relationship, a second annual cost, a data exchange layer between the two platforms and a coordination problem when methodology changes (such as PEFCR version updates) ripple across the stack. Brands need to budget for the integration not just the platforms.
What Stack Costs Look Like in Practice
The cost of a two-platform stack depends on the platforms involved and is rarely published in either platform's pricing material. The Renoon market analysis places mid-market DPP solutions in the €15,000 to €70,000 range. A two-platform stack typically sits at the higher end of that range or above, because each platform individually is priced for the full value it delivers in its layer.
For Retraced plus Carbonfact, or TrusTrace plus Peftrust, or Carbonfact plus a traceability platform like Retraced, the combined annual cost frequently exceeds €60,000 to €100,000 for mid-market brands. This is higher than either platform's individual licence and meaningfully higher than a single integrated platform priced for the same scope.
This is not a criticism of any specific vendor. It is a structural feature of the way the market has evolved, and it has direct implications for total cost of ownership comparisons.
What This Means for Procurement
For brands building a DPP procurement specification, three practical questions follow from the stack question.
Which layers are foundational for your specific catalogue and timeline? A brand selling primarily into the EU with a 2027 deadline needs all three layers credibly. A brand selling primarily into non-EU markets with longer regulatory exposure may have more flexibility on timing.
What total cost is the platform stack, not the headline licence? The headline licence consistently understates total cost where partner platforms are required. Procurement should ask the vendor directly about partner pricing and integration cost.
Where does the data live and who owns it? Data that flows between two platforms (traceability platform to LCA platform) introduces data ownership and portability questions that single-platform deployments do not. Both platforms have data on the brand's products; both contracts need to address data portability on exit.
A useful diagnostic question to ask any vendor: "If we sign with you today, what other platforms do we need to buy to publish a complete DPP, and what would those cost us?" Vendors who answer this directly are useful to evaluate further. Vendors who deflect are answering the question by deflecting.
When Stacks Are the Right Answer
Two-platform stacks are not always the wrong answer. They can be the right answer when:
- The brand already uses one of the layer platforms (often a traceability platform deployed before DPP became urgent) and the marginal cost of adding the second layer is lower than replacing the existing platform.
- The brand has highly specialised needs in one layer that an integrated platform cannot match. A luxury brand with deep authentication and resale ambitions may genuinely benefit from a specialist Layer 3 rendering platform.
- The brand is large enough that the procurement, integration and renewal cost of running two platforms is marginal relative to the value of best-in-class capability in each layer.
For most SME and mid-market fashion brands, the integrated platform path is more cost-effective and operationally simpler. But the stack path is sometimes genuinely the right structural choice.
How ENVRT Approaches the Stack Question
ENVRT LAB™ is built around all three DPP layers as native capability rather than as separate modules or integrated partners. The traceability data layer feeds the LCA engine, which feeds the DPP rendering, which surfaces scan analytics that flow back into the data layer. The methodology is aligned with ISO 14040 and PEFCR. The rendering is brand-aligned and designed for consumer engagement, not just regulatory compliance. The pricing is published as a single licence covering all three layers.
This is a structural choice rather than a feature choice. The alternative (selling each layer separately and partnering for the rest) is the dominant pattern in the category. We built differently because the procurement and integration cost of running stacks does not match the practical needs of the fashion brands we work with.
