The EU Carbon Border Adjustment Mechanism (CBAM) is adding a new dimension to credit-risk assessment for banks financing steel, aluminium and other carbon-intensive industries. As carbon-border obligations apply to goods imported from 2026, the reliability of industrial emissions data can influence borrowers’ cash flows, liquidity needs, export competitiveness and ability to service debt.
For lenders, the key question extends beyond whether a company operates in an emissions-intensive sector. It is whether its financial forecasts, expected export revenues and financing requirements rely on emissions figures that can withstand independent verification.
This distinction could affect existing corporate lending, new industrial investment, trade-finance facilities and refinancing decisions across Southeast Europe.
Emissions intensity enters credit assessments
Traditional credit analysis focuses on revenue, operating margins, leverage, liquidity, collateral and debt-service capacity. CBAM adds another consideration: the emissions intensity of goods sold into the EU market.
For EU importers, embedded emissions help determine certificate requirements, subject to the applicable calculation rules and adjustments. For producers outside the EU, the resulting costs can influence customer demand, negotiated prices and the continuation of long-term supply agreements.
A manufacturer with demonstrably lower emissions may have a competitive advantage over a rival facing higher carbon-cost assumptions. However, the value of that advantage depends on the product, applicable CBAM methodology, carbon prices and prevailing market conditions.
Banks must therefore distinguish substantiated emissions performance from unverified environmental claims. Existing carbon-footprint reports and sustainability certificates may provide useful background, but they do not automatically replace the emissions information required under CBAM.
This distinction is increasingly relevant for lenders with exposure to industrial borrowers that depend heavily on European customers.
Existing loan portfolios face changing assumptions
CBAM also creates a reassessment challenge for loans approved before the definitive regime began on 1 January 2026. Some borrowers may have developed business plans based on stable export volumes, customer pricing and production economics. Others may have expanded capacity in anticipation of continued access to European markets.
Carbon-border costs can change those assumptions even if production volumes remain unchanged. A steelmaker might continue operating at its existing output level while EU customers seek price concessions to offset additional costs. An aluminium producer may face greater scrutiny of its input materials and their emissions characteristics. A trader may need additional liquidity to manage imports and related compliance obligations.
These pressures can weaken debt-service capacity without an immediate decline in physical production.
Banks may therefore need to review material CBAM exposure within existing lending portfolios, rather than addressing it only when approving new credit. This does not mean that every exposed borrower requires refinancing or an impairment adjustment. It means lenders should test relevant financial assumptions against credible scenarios and document the results.
A layered approach to borrower due diligence
Assessing CBAM-related credit risk requires several distinct levels of analysis.
The first is commercial exposure. Lenders need to identify which products are covered, what proportion of the borrower’s output is sold to EU customers and whether supply contracts allow carbon-related costs to be passed through to buyers.
The second is installation-level performance. Relevant evidence includes production routes, fuel consumption, process emissions, material inputs, monitoring systems and the reliability of embedded-emissions calculations.
The third is verification readiness. Where a borrower intends to use actual emissions values, lenders should assess whether the supporting evidence is complete, whether a verifier with the appropriate accreditation scope is available and whether significant data-quality weaknesses remain unresolved.
The fourth is financial sensitivity. Credit analysts can model how changes in emissions intensity, carbon prices, output volumes and contractual cost allocation affect EBITDA, liquidity and debt-service ratios.
Finally, lenders should distinguish between the investment required to correct information weaknesses and the capital needed to reduce emissions physically. Some facilities may require upgraded measurement equipment or data infrastructure. Others may need comparatively limited improvements to documentation, consistency and traceability.
These expenditure categories represent different risks and should not automatically be treated as equivalent decarbonisation investments.
Renewable electricity does not automatically reduce CBAM costs
Electricity procurement is another area where incorrect assumptions can affect lending decisions. Companies may expect renewable power purchases to reduce their CBAM exposure, but the effect depends on the goods and the applicable rules.
Under the current framework, many covered iron, steel and aluminium products are assessed on the basis of direct emissions, while indirect emissions are included for relevant products in other sectors, notably cement and fertilisers. Renewable electricity procurement therefore does not automatically reduce the current CBAM certificate exposure of a steel or aluminium producer.
Imported electricity is itself a CBAM-covered good, and demonstrating actual emissions for electricity imports involves separate, more restrictive requirements.
Banks financing renewable generation, industrial power-purchase agreements or electricity imports must distinguish the general commercial value of renewable power from any specific CBAM benefit. A renewable energy project may remain commercially attractive without delivering the carbon-border advantage assumed in its financial projections.
The contractual structure and regulatory eligibility of any claimed benefit are therefore material to the credit assessment.
Evidence-readiness financing could create a new opportunity
Banks could respond to these requirements by developing dedicated CBAM evidence-readiness financing for industrial borrowers. The objective would be to improve the reliability of emissions information and protect access to EU markets, rather than to fund emissions reductions alone.
Potentially eligible expenditure could include calibrated metering, monitoring software, integration of production data, laboratory controls, emissions-calculation systems and independent technical assessments.
Financing could be linked to measurable milestones, such as completing a monitoring plan, resolving identified data gaps, obtaining an independent assessment of evidence readiness and completing accredited verification where required.
Such facilities could complement existing corporate loans, refinancing arrangements or wider industrial modernisation programmes. Covenants might require borrowers to maintain monitoring systems, preserve supporting records and report material verification findings.
Clear separation of responsibilities would be essential. A bank’s engineering adviser may assess the quality and completeness of the borrower’s evidence, but cannot replace the statutory verifier’s independent conclusion.
Banking regulation and regional exposure
The European Banking Authority’s ESG risk-management guidelines, applicable to most EU institutions from January 2026, establish broader expectations for identifying, measuring, monitoring and managing environmental and transition risks. They do not prescribe a standardised CBAM financing product or require identical assessments for every industrial borrower.
Nevertheless, CBAM provides a direct example of environmental regulation potentially affecting credit quality through operating costs, commercial relationships and liquidity requirements.
The implications extend to European banking groups financing clients in Serbia, Montenegro and neighbouring markets through subsidiaries, cross-border lending and trade-finance facilities. Regional lenders outside the EU framework may also have commercial reasons to conduct similar assessments, even where the EBA guidelines do not directly apply to them.
For banks with concentrated exposure to exporters serving European industrial customers, the mechanism adds another dimension to portfolio risk. Borrowers’ long-term viability increasingly depends on whether their production economics remain sustainable after applicable carbon-border costs are incorporated.
Emissions data is consequently moving beyond sustainability reporting into the financial assumptions used to assess liquidity, creditworthiness and industrial asset values. A borrower unable to substantiate the figures underpinning its export strategy may present a materially different credit risk from a competitor whose industrial performance can be independently demonstrated.
