Türkiye’s position as a major manufacturing partner for the European Union places its steel and aluminium supply chains in the focus of Carbon Border Adjustment Mechanism (CBAM)-related commercial pressure. Domestic mills and smelters provide materials to processors and original equipment manufacturers (OEMs). Machinery, household appliances, vehicles and components produced by those OEMs are then supplied into EU markets.
This role is described as a significant test case for the EU’s CBAM framework. The mechanism’s current coverage of basic materials is linked to potential implications of proposed downstream measures for 2028. The text also distinguishes between legal coverage and economic exposure, noting that manufacturers outside the six original CBAM sectors can still face pressure through carbon-intensive inputs, electricity costs, customer requirements and financing conditions.
Emissions information needs traceability across manufacturing
The supply chain runs from Turkish steel mills and aluminium smelters through domestic processors and OEMs to EU importers and industrial customers. As materials are transformed, blended or allocated between products, emissions information must remain traceable. This is intended to support the carbon value assigned to a finished component or an import declaration.
The requirement creates a need for controlled chain-of-custody systems across production and trade. Records are expected to connect upstream material origins and emissions with processing activities and the quantities delivered to European customers. The challenge is described as increasing as the number of products, installations and suppliers expands into the hundreds or thousands.
Turkish producers are also presented with commercial decisions on how to respond to carbon-related costs. Options include absorbing costs, passing them on to customers, or investing in decarbonisation. At the same time, the text notes that EU scrutiny of selective allocation of cleaner production to export markets makes consistent, verifiable emissions records important.
These requirements can affect supplier rankings in procurement decisions. A product with the lowest factory-gate price may not deliver the lowest carbon-adjusted landed cost for an EU customer when emissions profiles and associated costs are considered.
Upgrades rely on efficiency improvements and MRV-ready data
Manufacturers can address exposure through improvements in electric-arc furnace (EAF) efficiency, recycling, renewable electricity procurement and plant-level emissions monitoring. The text also references MRV, covering reporting and verification at facility level. Downstream manufacturers are described as needing supplier carbon clauses that specify how emissions information is provided and maintained across the value chain.
Mapping products, installations and supplier relationships early is described as a way to reduce retrospective reconstruction of data. The objective is to connect material and energy records with specific production outputs and shipments bound for the EU. This approach is contrasted with reliance on general corporate emissions figures that cannot be reconciled with individual products.
Verification readiness is described as depending on meter data, production routes, material flows, precursor emissions, product allocation and verified calculations tied to output destined for the EU. The closer the link between source records and reported values, the more confidently companies can use actual emissions information in negotiations with customers.
The text also states that a reliable evidence system can help distinguish physical decarbonisation from improvements in reporting. Cleaner production can reduce actual emissions, while stronger measurement and verification can substantiate results. It adds that both aspects are relevant but not interchangeable.
Financing assessments consider export exposure and transition spending
For lenders and investors, the assessment of Turkish industrial companies is described as considering concentration of revenue from EU customers. It also includes domestic carbon pricing development, access to renewable electricity, retrofit capital expenditure and whether customer contracts reward lower emissions.
The text says transition plans need to separate investments that reduce physical emissions from spending that improves emissions-data quality. It also distinguishes measures primarily intended to preserve market access. This separation is described as helping financial institutions evaluate purpose and expected impact rather than treating all carbon-related expenditure as equivalent.
Companies with significant EU sales may face different commercial consequences depending on their ability to pass through costs. The text links these outcomes to securing cleaner energy and demonstrating production performance. Where contracts do not allocate carbon-related costs or documentation responsibilities adequately, manufacturers and importers may be left exposed to costs arising elsewhere in the supply chain.
CBAM obligations sit with EU importers but pressure reaches upstream
For non-EU exporters, the formal obligation to surrender CBAM certificates generally rests with the EU importer. The text adds that commercial pressure still moves upstream because European buyers have incentives to favour suppliers able to provide verified actual emissions values. It also points to the need for reliable supporting documentation.
This is described as making CBAM readiness relevant for Turkish manufacturers even when they do not maintain an EU certificate account themselves. Their position in European supply chains is said to depend on the carbon profile of goods supplied. It also depends on their ability to substantiate those profiles in a form usable by customers and importers.
The text states that contracts should define responsibilities for emissions-data delivery, verification status, supplier changes, carbon-cost pass-through and remedies when evidence is late or unusable. It highlights that these provisions are important where the party carrying the formal import obligation has limited control over production decisions or material sourcing several tiers upstream.
Without clear contractual arrangements, EU importers may face costs linked to emissions information or production choices made by suppliers further along the chain. The text notes limited ability to recover those costs in such cases. For Turkish producers, it adds that clear responsibility allocation can determine whether decarbonisation investments and verified lower emissions translate into commercial value.
The text concludes by linking Türkiye’s extensive manufacturing ties with the EU to consequential relationships between carbon performance, production costs and data quality. As CBAM requirements shape purchasing and compliance decisions, steel and aluminium suppliers are described as being assessed not only on price, quality and delivery but also on their ability to document emissions across increasingly complex manufacturing chains.
