Iron, Steel and Aluminium DPP Requirements

Why Metals Are an ESPR Priority

Iron, steel, and aluminium are among the highest-emission product categories in the global economy. Steel production alone accounts for approximately 7 percent of global greenhouse gas emissions, and aluminium adds a further 2 to 3 percent depending on the production route. Together with iron, these three metals are responsible for roughly 10 percent of worldwide CO2 emissions, which is why they sit at the top of the European Union's Ecodesign for Sustainable Products Regulation (ESPR) working plan.

The ESPR introduces Digital Product Passports as the mechanism for collecting, verifying, and sharing the data needed to drive emissions reductions in these sectors. For producers of iron, steel, and aluminium, the Digital Product Passport is not a marketing label, it is a regulatory data carrier that downstream buyers, construction companies, automotive manufacturers, appliance makers, and packaging converters, will use to verify the environmental credentials of every tonne of metal they buy.

This guide sets out exactly what data Digital Product Passports for iron, steel, and aluminium will need to carry, when the delegated acts come into force, how the carbon-intensity reporting works, and a 7-step plan for producers to be ready.

Metals DPP at a Glance

The ESPR Timeline for Metals

The ESPR's roll-out for metals is staged. The European Commission has signalled the sequence through the published 2025 to 2030 working plan and through the prioritisation of delegated acts.

• July 2024: ESPR enters into force as Regulation 2024/1781, replacing the earlier Ecodesign Directive.
• 2025 to 2026: Commission consultations and impact assessments for the iron and steel delegated act.
• Mid-2026: EU DPP Registry comes online, providing the federated discovery infrastructure for all sector DPPs.
• 2026: Adoption of the iron and steel delegated act, setting the data fields and compliance dates for ferrous metals.
• 2027: Aluminium delegated act adopted, alongside textiles and tyres.
• 2028 to 2030: Compliance dates for the first iron, steel, and aluminium products to require a DPP at point of placement on the EU market.

The phased adoption gives producers a defined window to put data infrastructure, third-party verification, and supply-chain visibility in place. Producers that wait for the delegated acts to be finalised before starting work face a much harder operational task than those that begin building systems against the ESPR's known principles now.

Mandatory Data Fields for Metals DPPs

The exact data field list will be confirmed by the delegated acts, but the ESPR principles and the published working plans make the likely scope clear. The data needed falls into seven categories.

Product Identification

• Unique product identifier (likely a GS1 GTIN or equivalent serialised identifier)
• Batch or heat number for ferrous metals, cast number for aluminium
• Producer identification including economic operator details
• EU DPP Registry reference

Material Composition

• Alloy grade and chemical composition
• Recycled content percentage, broken out by post-consumer and post-industrial
• Source of primary inputs where applicable
• Presence of substances of concern under REACH and the related ESPR substances of concern framework

Production Route

• For steel: blast furnace and basic oxygen furnace, electric arc furnace, direct reduced iron, hydrogen reduction, or hybrid
• For iron: production process and ore source
• For aluminium: primary smelting or secondary recycling, electricity source classification
• Geographic location of each production stage

Carbon Intensity

• Greenhouse gas emissions per tonne of finished product
• Scope 1 (direct emissions from production)
• Scope 2 (energy-related emissions, with location-based and market-based variants)
• Scope 3 (relevant upstream supply chain emissions, particularly for iron ore and alumina inputs)
• Calculation methodology reference, typically aligned with EN 15804 or ISO 14067

Performance and Mechanical Properties

• Standard mechanical property data (tensile strength, yield strength, elongation)
• Coating or surface treatment specifications
• Dimensional tolerances and product form

End-of-Life and Recyclability

• Recyclability score and recommended end-of-life route
• Separation guidance for downstream recyclers
• Hazardous components that must be removed prior to recycling

Compliance and Verification

• Conformity declarations and test certificates
• Third-party verification status
• Audit trail for the data, including last update date

How Carbon Intensity Reporting Works

Carbon intensity is the single most operationally demanding data field on the list above, because it requires the producer to measure, allocate, and verify emissions across the full production process and parts of the upstream supply chain.

The Three Scopes Explained

The DPP carbon-intensity field follows the GHG Protocol scope structure that producers will already be familiar with from CSRD and CBAM reporting.

• Scope 1: Direct emissions from the producer's own facilities. For a steel mill, this includes coke ovens, blast furnaces, sinter plants, and on-site combustion. For an aluminium smelter, this includes anode consumption and on-site fuel combustion.
• Scope 2: Emissions from purchased electricity, steam, and heat. Aluminium is especially sensitive here because the electrolysis process is electricity-intensive. The DPP will require both location-based and market-based scope 2 figures, so producers using renewable PPAs can demonstrate the impact of clean electricity sourcing.
• Scope 3: Upstream emissions from purchased materials and services. For steel, the most material categories are iron ore, scrap inputs, alloying elements, and transport. For aluminium, alumina and bauxite mining dominate.

The Production Route Differential

The same finished product can carry very different embedded emissions depending on the production route used. Electric-arc-furnace steel made from scrap with renewable electricity can have emissions less than 0.5 tonnes of CO2 per tonne of steel, while integrated blast-furnace steel commonly exceeds 1.8 tonnes of CO2 per tonne. The DPP makes this difference visible to downstream buyers, which is precisely the policy outcome the European Commission is seeking.

Sector-Specific Considerations

Iron and Steel

Steel is on the fastest ESPR timeline, with the delegated act expected in 2026. Long products, flat products, and rebar are likely to be covered first, with downstream alloyed and coated products following. Steel producers should expect detailed disclosure of furnace technology, scrap input ratio, and carbon-capture deployment if applicable. The compliance burden will fall hardest on integrated mills with limited scope-3 visibility into ore and alloying inputs.

Aluminium

Aluminium follows in 2027. The defining issue for aluminium DPPs is electricity sourcing, because more than 60 percent of aluminium's lifecycle emissions typically come from smelter electricity. Producers using hydroelectric or other renewable power can use the DPP to demonstrate a competitive advantage, while smelters in coal-electricity grids face significant disclosure exposure. Secondary aluminium from scrap will have a dramatically lower carbon intensity and the DPP makes this contrast machine-readable for procurement systems.

Downstream Users in Construction, Automotive, and Packaging

Construction firms, automotive manufacturers, and packaging converters are not direct producers of metals, but they are buyers who will read DPPs at point of procurement. The construction sector in particular will use metals DPPs to feed embodied-carbon assessments under the revised Construction Products Regulation. Automotive manufacturers will read steel and aluminium DPPs into their own vehicle DPPs under the automotive sector requirements. This downstream pull is a powerful force that producers cannot ignore even before the delegated acts make compliance mandatory.

How to Choose a Calculation Methodology

The ESPR does not invent a new carbon-accounting methodology. It builds on established standards, and producers should align their DPP calculation approach with the methodologies most likely to be accepted by verifiers.

• EN 15804: The European standard for Environmental Product Declarations for construction products. Already widely used in the steel sector for EPDs.
• ISO 14067: The international standard for product carbon footprint quantification, useful for cross-border consistency.
• worldsteel CO2 methodology: Sector-specific methodology widely used by steel producers, aligned with ISO 14064.
• International Aluminium Institute LCA framework: The aluminium-sector equivalent, defining boundaries and allocation rules.
• CBAM reporting methodology: The Carbon Border Adjustment Mechanism methodology that is in force from 2026 and will need to be reconciled with DPP figures.

Producers that already produce EPDs for construction-product customers have a substantial head start. The same data infrastructure can feed both EPDs and DPPs, with the DPP adding the unique product identifier, data carrier, and registry linkage.

The Relationship Between DPPs, CBAM, and EPDs

Metals producers are facing several overlapping data demands at once. The ESPR DPP, the EU Carbon Border Adjustment Mechanism (CBAM), and Environmental Product Declarations (EPDs) all require carbon-intensity data, but they serve different purposes and have different verification regimes.

• DPP: Per-product data field accessible by all downstream actors and authorities, lifetime of the product.
• CBAM: Border adjustment payment calculation, quarterly reporting to customs authorities, applies to imports.
• EPDs: Voluntary product-category disclosures used in procurement and tendering, particularly construction.

The three frameworks overlap on scope 1 and 2 emissions but diverge on scope 3 treatment, verification, and presentation. Producers that build a single underlying data system feeding all three reduce duplication and audit risk significantly.

7-Step Action Plan for Metals Producers

1. Confirm which product groups apply. Map your SKU catalogue against the categories likely to be covered by the iron, steel, and aluminium delegated acts.
2. Inventory current data assets. List the EPDs, CBAM reports, ISO 14067 footprints, and procurement-facing disclosures you already produce.
3. Build a single product-data model. Design a unified data model that can satisfy DPP, CBAM, and EPD requirements from a single source of truth.
4. Engage iron-ore, alumina, and scrap suppliers. Scope 3 data quality will be your biggest gap. Issue data requests now and accept that supplier engagement takes 12 to 24 months to mature.
5. Select a verification partner. ESPR DPPs will require third-party verification of carbon-intensity data. Begin scoping which verifier you will use and what their audit-trail requirements are.
6. Pilot a DPP on one product line. Choose a single product family with the cleanest existing data and use it to test your full data pipeline, QR carrier, registry linkage, and consumer-facing presentation.
7. Set up internal governance. Assign clear ownership for DPP data quality, update cadence, and incident response. The DPP is a living data record for the lifetime of the product.

Frequently Asked Questions

When do iron and steel DPPs become mandatory?

The iron and steel delegated act is expected in 2026, with compliance dates set within the act, typically 18 to 36 months after adoption. Producers should plan for mandatory DPPs from 2028 onward.

When does the aluminium DPP take effect?

The aluminium delegated act is expected in 2027, alongside textiles and tyres. Compliance will follow on the timetable defined in the act.

What data must a metals DPP contain?

Mandatory fields include unique product identifier, material composition, recycled content, production route, carbon intensity by GHG scope, performance properties, end-of-life guidance, and compliance verification status.

How does the DPP relate to CBAM and EPDs?

All three require carbon-intensity data, but they serve different audiences. DPPs are per-product and consumer-facing, CBAM is for border-adjustment calculation, and EPDs are voluntary procurement disclosures. A single underlying data system can feed all three.

Do non-EU producers need to comply?

Yes. Any iron, steel, or aluminium placed on the EU market requires a DPP regardless of where it is produced. Non-EU producers face the same data requirements as EU-based producers.

Which calculation methodology should we use for carbon intensity?

The most widely accepted methodologies are EN 15804 (construction context), ISO 14067 (general product carbon footprint), the worldsteel CO2 methodology for steel, and the International Aluminium Institute LCA framework. Align with whichever methodology your verifier accepts.

What is the EU DPP Registry and when does it launch?

The EU DPP Registry is the central federated index that allows market authorities, downstream buyers, and consumers to discover and verify Digital Product Passports. It is expected to come online in mid-2026.

How does the DPP show production route differences?

The production route field is explicit. Electric-arc-furnace steel made from scrap with renewable electricity will show a much lower carbon-intensity figure than integrated blast-furnace steel, and the DPP makes this contrast machine-readable for procurement systems and consumer-facing comparisons.

Conclusion

Metals are at the front of the ESPR's Digital Product Passport rollout because they account for roughly 10 percent of global emissions and because the production-route differences between low-carbon and high-carbon producers are substantial and policy-relevant. Iron and steel delegated acts are expected in 2026, aluminium in 2027, with compliance dates following on the timetable each act defines.

For producers, the path forward is clear. Build a single product-data model that satisfies DPP, CBAM, and EPD requirements together, engage upstream suppliers on scope 3 data quality, select a verification partner early, and pilot a DPP on one product line before the delegated acts force the issue across your full catalogue. Producers that begin this work now will be substantially better placed than those that wait, and the DPP will become a competitive instrument as much as a compliance one.
