European foundries and metal fabricators face growing pressure to account for emissions across production processes as the EU’s Carbon Border Adjustment Mechanism (CBAM) connects the carbon characteristics of imported metals with the competitiveness of downstream manufacturing. These businesses inherit emissions from pig iron, steel and aluminium while adding their own emissions from electricity, gas, scrap treatment, casting, welding and heat treatment.
The exposure extends across industrial supply chains serving automotive, machinery and infrastructure customers. Under the current CBAM framework, the carbon intensity of basic materials can influence costs well beyond the initial import transaction, while proposed downstream measures for 2028, where relevant, could extend the mechanism’s reach further into manufactured products.
For foundries and fabricators, the challenge is to connect emissions associated with incoming materials to the energy consumption, production losses and finished components generated at their own facilities.
Production processes carry emissions through the supply chain
The manufacturing chain begins with metal feedstock and continues through furnace charging or fabrication, processing energy, material yield losses and component production. Emissions associated with the original metal can remain commercially significant through several subsequent transactions, particularly when downstream manufacturers cannot easily replace the material or renegotiate fixed-price customer contracts.
Mid-sized processors face a potential cost imbalance when lower-carbon metal commands a higher purchase price but customers demand products with lower emissions footprints without fully compensating suppliers for the additional expense. This can place pressure on margins where manufacturers have limited pricing power.
A single corporate carbon footprint cannot adequately address every transaction in this chain. Buyers and importers increasingly need emissions information at the product and production-installation levels, supported by records that can be reconciled with actual traded quantities.
The ability to distinguish emissions associated with different production routes and individual batches can therefore influence purchasing decisions. Where the underlying evidence is incomplete, customers may incorporate uncertainty into transaction pricing rather than rely on unsupported emissions claims.
Furnace records and energy metering underpin emissions verification
Foundries and fabricators need production controls that connect material inputs with energy consumption and finished output. Key measures include maintaining furnace-charge records, segregating materials where appropriate, expanding meter coverage, tracking production yields and allocating emissions to individual products.
These processes must integrate with existing manufacturing controls rather than operate solely as a customs or sustainability reporting exercise. Reported emissions values need to remain traceable to the physical production process, including the materials consumed, energy used and quantities produced.
A credible verification file should contain supplier metal data, internal meter readings, batch records, scrap-treatment information, production quantities, allocation rules and a calculation trail that an independent verifier can reconstruct.
This evidence can have a direct commercial effect. When actual emissions values support a lower carbon-adjusted cost, the documentation can strengthen a supplier’s position in negotiations. Weak or incomplete records may instead lead buyers to price in uncertainty, reducing the commercial benefit of investments in lower-emissions production.
Decarbonisation investment depends on cost recovery
Potential investments include electric furnaces, more efficient burners, heat recovery systems, renewable electricity and digital metering. These measures require capital expenditure (CAPEX), with their commercial viability depending partly on whether customers recognise and compensate for the resulting emissions reductions or improved data quality.
Financing assessments need to examine the relationship between investment costs, operating performance and the ability to recover carbon-related expenses through sales contracts. Banks should distinguish between carbon-cost pass-through that is explicitly established in contractual terms and recovery that management merely assumes will be possible.
Where customers resist higher prices, a processor may struggle to recover the additional cost of lower-carbon inputs or decarbonisation investments. Limited pricing power can turn a manageable regulatory expense into a material margin shock.
Purchase and sales agreements should consequently establish clear provisions for emissions-data delivery, verification status, supplier changes, carbon-cost pass-through and remedies when documentation is late or unusable. Without these arrangements, a company carrying a legal CBAM obligation may inherit costs originating several tiers upstream without an effective means of recovering them.
EU ETS changes increase the importance of long-term sourcing
CBAM is being phased in alongside the reduction of corresponding free allocation under the EU Emissions Trading System (EU ETS), with the phase-out extending towards 2034. For primary metals, the commercial difference between efficient and carbon-intensive production routes is expected to widen over time rather than remain at its 2026 level.
Foundries and fabricators therefore need to assess metal sourcing over several years, considering how changes in the carbon-cost framework may affect input prices and the competitiveness of finished components.
This longer-term approach also requires businesses to maintain emissions records that remain usable across customer transactions and production stages. Supplier data, internal energy measurements and product-level allocations must collectively demonstrate how the carbon characteristics of incoming metals relate to the finished goods supplied.
The foundry and fabrication stage is a critical link between primary metal production and final manufacturing. Its ability to preserve emissions information through casting, processing and component production will influence how reliably carbon data moves through European industrial supply chains and how suppliers are assessed by their customers under the evolving CBAM framework.
