The expansion of accredited verification under the EU Carbon Border Adjustment Mechanism (CBAM) is bringing a new set of commercial risks into focus. As auditors begin examining emissions data from steelworks, aluminium smelters and other industrial facilities outside the EU, the credibility of their technical assessments and the extent of their financial accountability are becoming increasingly important to importers, exporters, commodity traders and lenders.
An inaccurate verification outcome could affect CBAM certificate obligations, procurement costs, contractual settlements and financing assumptions. The financial consequences may extend beyond the organisation that directly commissioned the assessment, particularly when an EU importer relies on emissions information verified for a third-country producer.
The challenge has therefore moved beyond establishing an accreditation framework. Its effectiveness will depend on whether verification bodies can demonstrate the industrial expertise needed to test complex emissions calculations, identify weaknesses in production records and take appropriate professional responsibility for their conclusions.
Accreditation expands, but technical competence remains installation-specific
In September 2026, Greece’s Hellenic Accreditation System extended the accreditation of EmiCert S.A. to cover all 11 CBAM verification activity groups, including iron and steel, aluminium, cement, fertilisers, hydrogen and imported electricity. The company entered the market with existing emissions-verification experience, including work associated with the EU Emissions Trading System.
Accreditations have also emerged in Italy and Sweden. By 13 October 2026, five verification bodies had been documented as accredited across the three countries.
These developments establish the initial infrastructure for independent verification ahead of the first annual CBAM declarations covering 2026 imports, which EU importers must submit by 30 September 2027.
The breadth of EmiCert’s accreditation raises a wider question about how verification organisations demonstrate competence across industrial activities as different as blast-furnace steelmaking, aluminium electrolysis, fertiliser manufacturing and cross-border electricity transactions.
The distinction between organisational accreditation and the expertise required for an individual assignment is central. EU rules do not require every auditor working for a broadly accredited organisation to possess detailed knowledge of every industrial process. Instead, verification bodies must deploy appropriately qualified personnel, assess the competence needed for each engagement and use technical experts when required.
Broad accreditation is therefore not, on its own, evidence of insufficient expertise. Nor does it guarantee that every assessment performed under that accreditation will be reliable. The decisive test is whether the verification team can substantiate its conclusions for the particular installation and activity being examined.
Steelmaking requires more than conventional emissions accounting
The technical challenge is particularly pronounced for large integrated steelworks in China, India, Türkiye and other major exporting markets. Facilities using blast furnaces and basic oxygen furnaces have different emissions characteristics from electric arc furnace plants that rely heavily on scrap.
For integrated production, emissions assessments can depend on the composition of raw materials, coke consumption, reducing agents, process gases, fuel use, production yields and the allocation of emissions among different outputs. A credible examination must follow the relationship between iron ore inputs, coke ovens, sintering, blast-furnace operations, steel conversion and finished products.
At electric arc furnace facilities, the assessment places different demands on the verifier, including scrutiny of metallic inputs, electrode consumption, fuel use, operating conditions and the treatment of emissions associated with relevant precursor materials.
Auditors must also distinguish CBAM-specific system boundaries and calculation requirements from broader lifecycle carbon accounting.
An environmental product declaration or conventional product carbon footprint is not automatically a CBAM-compliant emissions assessment. Such documents may provide useful supporting evidence, but the verifier must establish whether the calculations, installation boundaries and production records meet the applicable CBAM requirements.
Digital reporting tools cannot replace evidence from the plant itself. Production records, laboratory results, fuel invoices, material balances, monitoring systems and output volumes must support the reported emissions figures. Where precursors originate at separate installations, their provenance, quantities and embedded emissions create additional verification requirements.
Errors may result from deliberate misrepresentation, but they can also arise through incorrect methodologies, unsuitable system boundaries, missing precursor data or inconsistencies between production records. These risks affect steelmakers in both EU and non-EU markets. China’s industrial scale and the technical diversity of its steel sector, however, create a particularly demanding environment for teams lacking practical metallurgical experience.
A verifier may understand emissions accounting yet lack the operational knowledge needed to challenge the assumptions underlying a plant’s inventory. That gap could become a defining issue during CBAM’s first full verification cycle.
Accreditation does not guarantee recovery of financial losses
The European framework establishes safeguards intended to protect verification quality. Verification bodies must demonstrate technical competence and independence, conduct risk-based examinations and remain subject to oversight by national accreditation bodies. Competent authorities may also review verification conclusions.
The framework operates on the basis of reasonable assurance, not an absolute guarantee that every reported figure is correct. This distinction becomes commercially significant when companies have already relied on a verified report to determine their exposure or negotiate supply arrangements.
Consider an illustrative importer purchasing 250,000 tonnes of steel annually. If the embedded-emissions assessment understates emissions by 0.4 tonnes of CO₂ per tonne of steel, the total discrepancy would amount to 100,000 tonnes of CO₂.
At an assumed carbon price of €80 per tonne, that difference represents €8 million in gross carbon-price exposure, before accounting for CBAM free-allocation adjustments, recognised carbon prices paid abroad and other applicable calculations. This is an illustration of the potential scale of an emissions-data error, not an estimate of an actual CBAM liability.
A material misstatement could result in additional certificate obligations, declaration corrections, commercial disputes and penalties where the relevant legal conditions are met.
Responsibility is distributed across the supply chain. The EU importer remains responsible for its CBAM declaration, while the producer must provide accurate underlying industrial information. The verifier has separate professional obligations relating to the assessment and conclusion it issues.
European accreditation requirements and ISO/IEC 17029 establish mechanisms concerning competence, independence and liability management. However, these requirements do not automatically give every importer an enforceable right to recover its full financial loss from a verification body.
Recovery may depend on national law, contractual terms, professional negligence, causation, insurance coverage and whether the importer has direct enforceable rights against the verifier. The position can be especially complicated when the verifier’s client is a non-EU producer rather than the European importer that subsequently relies on the report.
For major supply chains, verification must consequently be assessed as both a regulatory control and a contractual risk-allocation issue.
Lenders and insurers must assess verification risk
Banks financing industrial production, commodity inventories and cross-border trade have a direct interest in the reliability of emissions data. Credit institutions already assess carbon exposure when financing steel, aluminium and other emissions-intensive industries. CBAM strengthens the connection between emissions calculations and future import costs, creating the possibility that inaccurate data will distort financial forecasts.
An importer relying on understated emissions could underestimate its working-capital needs. An exporter whose low-carbon claims prove inaccurate could face demands to renegotiate prices, lose competitiveness or become involved in disputes with EU customers. A lender supporting an expansion based on expected premiums for low-carbon exports could also find that the underlying assumptions are no longer sustainable.
This creates a case for incorporating verification quality, technical evidence and contractual liability into conventional credit due diligence.
For larger transactions, lenders may need to establish whether the verifier’s accredited scope covers the relevant industrial activity, whether the assigned team has suitable experience and whether the underlying production information can be traced to reliable records. Professional indemnity insurance, contractual liability limits and procedures for correcting verification findings may also become relevant.
Insurers face a related question: how existing professional liability policies respond to losses arising from regulatory emissions verification. A verified report may be essential for compliance without functioning as a comprehensive financial guarantee.
The difference between those two roles could attract greater attention as the value of CBAM obligations increases.
Southeast European producers face distinct technical demands
The issue is particularly relevant to steel, aluminium, electricity and other CBAM-related industries in Serbia, Montenegro, Bosnia and Herzegovina, North Macedonia and Albania. Facilities across the region vary in age, technology, monitoring arrangements and emissions intensity.
Some operators have established systems for emissions monitoring and international environmental reporting. Others may need to strengthen monitoring infrastructure, data management and the documentation supporting their reported figures.
The demands increase where production depends on several fuel sources, externally purchased precursors or complex electricity supply arrangements. Electricity verification involves a distinct set of technical questions concerning generation data, metering, contractual eligibility and, where actual emissions treatment is claimed, the relevant physical-delivery evidence.
Expertise in steelmaking cannot automatically be treated as equivalent to expertise in electricity trading, power scheduling or cross-border grid arrangements. Equally, specialists in electricity markets may not have the process-engineering knowledge needed to assess emissions from steel or aluminium production.
This creates a role for independent engineering specialists supporting installations before formal verification. Preparatory work can include reviewing process boundaries, metering systems, production data, material balances, precursor records and supporting documentation, helping companies assemble a more complete evidence package before an audit begins.
However, technical preparation must remain separate from statutory verification. An engineering consultancy can help a producer prepare its records, but it cannot replace the independent conclusion of an appropriately accredited verifier. Potential conflicts of interest must also be controlled when verification bodies engage external specialists.
A credible operating model does not necessarily require every verification company to employ specialists in every sector directly. It requires demonstrable competence, qualified multidisciplinary teams and controlled procedures, with the verification body retaining responsibility for its conclusions.
The first verification cycle will test the market’s credibility
The first accreditations mark the beginning of CBAM’s operational verification market, rather than establishing that the system has already succeeded or failed. The EU has introduced rules on competence, independence and oversight, alongside procedures for challenging inadequate verification and addressing failures to meet accreditation requirements.
How effectively these safeguards work will become clearer as verification expands to complex industrial installations across different jurisdictions.
One concern is that rapid market growth could encourage providers to prioritise broad service coverage and low-cost delivery before building sufficient industrial expertise and financial resilience. That would expose producers and importers to risks the accreditation framework is intended to reduce.
Verification bodies investing in metallurgical, chemical, electrical and process-engineering capabilities could instead gain a competitive advantage over providers relying predominantly on general emissions-accounting skills. For EU importers comparing similar services, the quality of technical examinations, the independence of conclusions and the adequacy of liability arrangements may become important differentiators.
The credibility of Europe’s first accredited CBAM verifiers will ultimately depend less on the number of accreditation certificates issued than on the reliability of the industrial evidence behind their reports. When a material error produces a financial claim, the parties will have to establish what went wrong, which responsibilities applied and how the resulting costs should be allocated.
