Digital Product Passports: A Practical Guide for Sustainable Value Chains

Introduction

Digital Product Passports, often shortened to DPPs, are emerging as one of the most important tools in the shift toward more transparent, circular, and lower-carbon product value chains. In simple terms, a Digital Product Passport is a structured digital record that carries key information about a product, component, or material across its lifecycle.

This information can include what a product is made of, where its materials come from, how it was manufactured, how it should be repaired or reused, and how it can be recycled or safely treated at the end of life. The aim is not simply to create another compliance document. The broader goal is to make product data more accessible, interoperable, and useful for companies, consumers, recyclers, repair providers, regulators, and other actors across the value chain.

The concept is especially important in the European Union, where Digital Product Passports are being developed as part of the Ecodesign for Sustainable Products Regulation, or ESPR. The European Commission has stated that technical preparation for the DPP rollout is already underway, including work on identifiers, data carriers, access rights, a DPP registry, and a web portal.

What is a Digital Product Passport?

A Digital Product Passport is best understood as a digital information layer attached to a physical product. It is accessed through a data carrier, such as a QR code, NFC tag, barcode, or another machine-readable identifier. When scanned, that identifier connects the user to product-specific information.

CIRPASS, an EU-funded initiative focused on preparing the ground for Digital Product Passports, defines a DPP as a structured collection of product-related data with a predefined scope, agreed data management rules, and access rights. It is conveyed through a unique identifier and made accessible electronically through a data carrier.

The “passport” metaphor is useful because the DPP travels with the product through different stages of its life. However, unlike a human passport, not every viewer will necessarily see the same information. A consumer may see repair instructions, durability information, or recycled content claims. A recycler may need material composition and disassembly guidance. A market surveillance authority may need access to compliance documentation. A supplier or manufacturer may need more detailed technical data, some of which may remain commercially sensitive.

Why Digital Product Passports Matter?

Digital Product Passports matter because many sustainability goals depend on better product-level information. Companies cannot easily reduce emissions, improve circularity, or verify responsible sourcing if they do not know what is in their products, where inputs come from, or how products behave after sale.

Today, product information is often fragmented. Some data sits with suppliers, some with manufacturers, some with logistics providers, some with retailers, and some with recyclers. Information may be stored in incompatible systems, spreadsheets, PDF declarations, certificates, or procurement platforms. In complex supply chains, especially for electronics, textiles, batteries, vehicles, and construction products, this creates a visibility problem.

DPPs are designed to address that problem by creating a more consistent way to organise and share product information. Their purpose is closely linked to sustainability, circularity, value retention, reuse, remanufacturing, recycling, consumer choice, and compliance verification.

For net zero strategies, this matters because emissions are often concentrated outside a company’s own operations. Many companies report that Scope 3 emissions, including purchased goods and services, use of sold products, transport, and end-of-life treatment, represent the largest share of their carbon footprint. Product passports will not automatically solve Scope 3 accounting, but they can improve the underlying data infrastructure needed to estimate, verify, and reduce value-chain emissions.

A Practical Example: the Digital Product Passport for a Smartphone

A smartphone is a useful example because it contains many materials, components, suppliers, and lifecycle impacts.

A Digital Product Passport for a smartphone could include:

• Product model, serial number, manufacturer, and unique product identifier.

• Key materials, such as aluminium, glass, plastics, copper, lithium, cobalt, nickel, gold, rare earth elements, and graphite.

• Information on recycled content in casing, packaging, or selected components.

• Battery chemistry, battery capacity, expected lifetime, and safe handling instructions.

• Repairability information, including spare part availability and disassembly guidance.

• Software support period, where relevant to product durability and useful life.

• Carbon footprint information, where required or voluntarily disclosed.

• Compliance declarations for relevant EU product rules.

• End-of-life instructions for collection, recycling, and safe disposal.

Different actors would use this information in different ways. A consumer could compare durability or repair options. A repair shop could access parts and disassembly guidance. A recycler could identify valuable materials and hazardous substances. A regulator could check whether the product meets applicable requirements. A manufacturer could use aggregated data to improve design, supplier engagement, and circular economy planning.

How DPPs Connect to Supply Chain Tiers

Digital Product Passports are closely linked to supply chain tiering. A finished product is rarely made by one company. It is usually the result of a multi-tier supply chain involving raw material extraction, refining, component manufacturing, assembly, logistics, retail, use, repair, and end-of-life treatment.

For a smartphone, Tier 1 suppliers may include final assemblers. Tier 2 suppliers may include battery, display, camera, and circuit board manufacturers. Tier 3 and Tier 4 actors may include semiconductor stages, chemical suppliers, refiners, and mining companies. Tier 5 or “Tier N” actors may include energy suppliers, transport providers, equipment makers, and other upstream enablers.

A DPP does not necessarily require every actor to disclose every detail publicly. However, it increases the need for structured traceability. Companies may need to know which suppliers hold which data, how reliable that data is, whether it can be verified, and which information must be shared with downstream users or authorities.

This is why DPP implementation is not only a technology project. It is also a supply chain governance project. Companies will need clear rules on data ownership, supplier requests, verification, confidentiality, and interoperability.

Key Data Categories in a Digital Product Passport

The exact data requirements will depend on the product category and the applicable regulation. However, most Digital Product Passports are likely to include several broad categories of information.

1. Product identification

This includes the product name, model, batch, serial number, manufacturer, and unique identifier. Without strong identification, a DPP cannot reliably connect digital information to the correct physical product.

2. Material composition

Material data helps recyclers, repair providers, manufacturers, and regulators understand what a product contains. This can support hazardous substance management, recycled content claims, recovery of critical raw materials, and circular design.

3. Environmental performance

Depending on the product category, this may include carbon footprint, energy efficiency, recycled content, durability, water impacts, or other lifecycle indicators. The EU’s broader product policy direction is to make sustainability performance more transparent and comparable.

4. Repair, reuse, and maintenance information

A DPP can help extend product life by making repair manuals, spare part information, maintenance guidance, and disassembly instructions easier to access.

5. Compliance documentation

Regulators and market surveillance authorities may use DPPs to verify whether products meet specific legal requirements. The European Commission has indicated that work is underway on access rights, identifiers, data carriers, registry infrastructure, and supporting tools for DPP deployment.

6. End-of-life information

End-of-life data can help recyclers and waste operators process products safely and recover more value. This may include disassembly steps, hazardous components, material recovery guidance, or collection instructions.

Which Sectors are Likely to be Affected First?

Digital Product Passports are expected to develop gradually, with product-specific rules introduced over time. The EU’s preparatory work has focused heavily on complex value chains where circularity, traceability, and sustainability data are especially important.

CIRPASS originally focused on electronics, batteries, and textiles. Its successor, CIRPASS-2, is demonstrating functioning Digital Product Passports in real settings across textiles, electrical and electronic equipment, tyres, and construction value chains.

Batteries are especially important because the EU Battery Regulation introduces battery passport requirements for certain battery categories. This makes batteries one of the first major practical test cases for product passports in Europe.

Textiles are another likely priority because of concerns around fast fashion, waste, fibre composition, recyclability, and supply chain transparency. Electrical and electronic equipment is also highly relevant because these products often contain critical raw materials, complex components, short replacement cycles, and significant repairability challenges.

Construction products may also become an important DPP use case because buildings and infrastructure depend on large volumes of materials, long product lifetimes, embodied carbon data, and increasingly detailed circularity information.

Why DPPs are Relevant for Net-Zero?

Digital Product Passports are not climate policies in the narrow sense. They do not directly set emissions caps, carbon prices, or renewable energy targets. Their importance lies in the information infrastructure they create.

For net-zero strategies, better product data can support:

• More accurate Scope 3 emissions accounting.

• Product-level carbon footprinting.

• Supplier engagement and procurement decisions.

• Identification of high-impact materials and components.

• Circular business models such as repair, resale, reuse, remanufacturing, and recycling.

• Verification of recycled content and low-carbon material claims.

• Better end-of-life treatment and material recovery.

For example, a company trying to reduce the carbon footprint of a laptop, battery, garment, or building material needs reliable data about material inputs, energy sources, manufacturing stages, transport, durability, and disposal. A DPP can help organise that information into a more consistent and reusable format.

However, a DPP should not be confused with a full life cycle assessment. It may contain LCA-based indicators, such as product carbon footprint data, but it is broader than a single environmental metric. It is a data-sharing mechanism that can support many use cases, including compliance, circularity, repair, consumer information, and market surveillance.

Implementation Challenges

Despite their potential, Digital Product Passports will be difficult to implement well.

Data availability

Many companies do not yet have reliable product-level data across their supply chains. Data gaps are especially common beyond Tier 1 suppliers. Smaller suppliers may lack digital systems, carbon accounting capacity, or standardised documentation.

Interoperability

DPP systems need to work across industries, platforms, countries, and supply chains. If each company builds a closed, incompatible passport system, the result could be more fragmentation rather than less.

This is why initiatives such as CIRPASS-2 are focusing on standardisation, pilots, and cross-sector interoperability. CIRPASS-2 aims to deploy and validate DPPs at scale through real-life pilots and to support standardisation and SME uptake.

Confidentiality

Some product data is commercially sensitive. Suppliers may be reluctant to disclose exact formulations, sourcing relationships, technical specifications, or production details. DPP systems, therefore, need access rights that distinguish between public, restricted, and authority-only information.

Verification

A DPP is only useful if the data is trustworthy. Companies will need processes for data quality checks, supplier declarations, audit trails, certification, and third-party verification where required.

Cost and SME readiness

Small and medium-sized enterprises may face significant administrative and technical burdens. For DPPs to work at scale, implementation will need practical tools, phased requirements, guidance, and affordable digital infrastructure.

What Companies Should do Now?

Companies do not need to wait until every product-specific rule is finalised before preparing. The direction of travel is already clear: product-level sustainability data is becoming more important.

A practical preparation plan could include:

1. Map product data already available
   Identify what information exists today across procurement, design, compliance, sustainability, logistics, and after-sales teams.

2. Prioritise high-risk product categories
   Start with products likely to face earlier requirements, such as batteries, electronics, textiles, tyres, construction products, or products with complex material composition.

3. Connect DPP work with Scope 3 accounting
   Product passports and Scope 3 reporting should not be treated as separate data exercises. Both depend on supplier data, material flows, emissions factors, and traceability.

4. Engage suppliers early
   Suppliers may need time to provide product-level data in structured formats. Procurement teams should clarify expectations before requirements become urgent.

5. Review digital systems
   Companies may need product information management systems, LCA tools, supply chain traceability platforms, ESG data systems, or integration between existing enterprise systems.

6. Define access and governance rules
   Decide who owns the data, who can edit it, who verifies it, and which information can be public, restricted, or confidential.

7. Monitor EU delegated acts and sector guidance
   The ESPR creates the framework, but many details will come through product-specific rules. Companies should track requirements for their own product categories.

Common Misconceptions

“A DPP is just a QR code”

The QR code or data carrier is only the access point. The real value lies in the structured, verified, and interoperable data behind it.

“DPPs are only for consumers”

Consumers are one audience, but DPPs are also designed for regulators, suppliers, repairers, recyclers, manufacturers, importers, and other economic actors.

“DPPs will make all supply chain data public”

Not necessarily. Access rights are a central part of the DPP concept. Different users may see different levels of information.

“DPPs automatically prove sustainability”

A passport can improve transparency, but it does not automatically make a product sustainable. The quality of the underlying data, the ambition of product requirements, and the credibility of verification all matter.

Conclusion

Digital Product Passports are set to become a core part of sustainable product policy, especially in the European Union. Their importance goes beyond compliance. They provide a practical structure for connecting product design, supply chain traceability, circular economy goals, consumer information, repairability, recycling, and climate-related data.

For companies, the main challenge is not only creating a digital label. It is building the internal and supplier-level data systems needed to support credible product transparency. That means mapping supply chains, improving material data, integrating sustainability information into product systems, and preparing for more detailed regulatory expectations.

For net zero and circular economy strategies, Digital Product Passports could become a crucial bridge between ambition and implementation. They help turn abstract goals such as lower emissions, better resource efficiency, and extended product lifetimes into product-level information that can be used, checked, and acted on.
