The expansion of the European Union’s Carbon Border Adjustment Mechanism (CBAM) is creating demand for technical specialists to examine emissions evidence at industrial facilities worldwide. Accredited verification organisations preparing to assess steelworks, aluminium producers, electricity generators and other installations outside the EU may rely on local engineering companies for technical work.
Verification requires evidence that reported emissions correspond to industrial processes, monitoring systems, production records and measured energy and material flows. For international assurance providers, this creates operational demands covering technical competence, staffing, geographical coverage and access to installations.
Engineering companies in Serbia, Montenegro and other non-EU markets could supply some of the expertise needed. Participation depends on how activities are distinguished between technical assistance and formal independent verification, alongside compliance with accreditation, competence and impartiality requirements.
CBAM definitive phase and verification milestones
CBAM entered its definitive phase on 1 January 2026, creating carbon-related obligations for specified imports linked to the EU Emissions Trading System (EU ETS). The mechanism covers six groups of goods: iron and steel, aluminium, cement, fertilisers, hydrogen and electricity.
Where importers use actual embedded emissions, the emissions information must be independently verified by an appropriately accredited body. Because many covered goods originate at installations outside the EU, the verification process requires international cooperation between foreign producers, assurance organisations and authorised declarants within the Union.
The European Commission’s timetable envisages verification activities beginning in September 2026, including documentary assessments and installation visits. Accredited verifiers can issue the first formal reports through the CBAM Registry from January 2027, enabling operators to provide verified actual-emissions information to authorised declarants.
The first annual declarations covering 2026 imports are due by 30 September 2027. Installation operators must prepare annual emissions reports, verification bodies must complete technical assessments, and EU declarants must obtain verified information before finalising declarations.
Roles in independent verification
Responsibilities are divided across parties involved in CBAM reporting. The installation operator generates monitoring information, the accredited verifier independently assesses that information, and the authorised declarant uses the verified data in its declaration under applicable CBAM requirements.
No single participant necessarily controls the entire process. Coordination becomes particularly important when installations involve complex production technologies, multiple manufacturing stages or several sources of emissions information.
Evidence requirements for industrial installations
CBAM verification involves more than reviewing administrative records or checking emissions calculations in spreadsheets. The verifier must determine whether reported figures are supported by appropriate monitoring methods and evidence reflecting physical operation of the installation.
This requires understanding of processes generating emissions, measurement system locations and functions, and methods used to allocate emissions to individual goods. Technical requirements vary by industry and installation type.
For a steelworks assessment, evidence may include process fuels, production routes, purchased precursors, material balances and relationships between intermediate and finished products. For aluminium installations, verification may cover process-specific emissions, fuel consumption, production volumes and allocation of emissions between relevant goods.
Power-generation facilities require a different combination of evidence such as fuel records, operating data, generation metering and technical evidence used to establish emissions associated with electricity production. Errors can occur even when instruments appear to function correctly if measurement boundaries or material balances are defined incorrectly or monitoring procedures are not properly documented.
An installation may also keep reliable aggregate production records without sufficient evidence for a particular product-level calculation. These issues require industrial engineering knowledge alongside emissions-accounting expertise, while the accredited verifier retains responsibility for deciding whether evidence is sufficient and reliable.
Accreditation scope under EU legal framework
The principal legal framework includes Regulation (EU) 2023/956, Commission Implementing Regulation (EU) 2025/2546 and Commission Delegated Regulation (EU) 2025/2551. The delegated regulation sets requirements on accreditation, verifier competence, impartiality, oversight and use of external technical resources.
The framework draws on conformity-assessment principles including EN ISO/IEC 17029, while introducing CBAM-specific requirements. Accreditation must be granted by a competent EU national accreditation body for the relevant activity scope.
The competence required varies between regulated activities across different categories of primary steel production, downstream steel products, aluminium production and electricity. A verification organisation qualified for cement cannot automatically assume it has competence needed for electricity-import verification or complex metallurgical processes.
Existing EU ETS verification organisations can apply to extend their accreditation scopes to cover relevant CBAM activities. The same route into the market does not remove the requirement to demonstrate sector-specific competence.
The regulatory framework also allows legal entities established outside the EU to seek accreditation from eligible EU national accreditation bodies. Accreditation still requires more than industrial experience, including appropriate personnel arrangements, procedures, quality management systems, professional competence, independence controls and documentation for oversight by accreditation bodies.
Local engineering support across Serbia and neighbouring markets
International verification organisations need personnel combining knowledge of regulatory requirements with capability to assess industrial data and production systems. Maintaining permanent teams covering every relevant technology in every exporting country may be economically inefficient.
A verification organisation headquartered in western Europe may require specialised knowledge of a Serbian steelworks or a Turkish aluminium facility or a power station in the Western Balkans. Although verification methods are harmonised at EU level, installations differ in technology type, age of equipment, instrumentation and operating practices.
Local engineers can contribute knowledge of equipment characteristics, production systems, plant records and operating conditions. Their presence can also support communication with installation personnel and access to technical information used during assessments.
A steel-related assignment may require familiarity with furnace operations, process-gas measurement or material accounting. Electricity-related work may require expertise in generator metering, control systems, transmission nominations or power-market arrangements; aluminium assignments may need specialists familiar with production routes, process measurements and precursor calculations.
The value of local participation lies in combining this technical knowledge with an accredited organisation’s verification methodology. Regional specialists could support selected assignments to reduce avoidable travel while providing skills needed only for particular installations or technologies.
Technical experts versus outsourced verification activities
The EU accreditation framework provides two principal routes for accredited verifiers to access additional technical expertise. One route involves engaging individual technical experts under Annex II of Regulation (EU) 2025/2551 to perform specified tasks under direction of appropriate members within the verification organisation.
A technical expert can assess characteristics of a metering system or explain an industrial process or examine evidence concerning specific production technology. Findings become part of the verification process but do not result in independent issuance of a verification opinion by that expert.
The second route involves outsourcing permitted verification activities under Section 1.7.4 of Annex II to Regulation (EU) 2025/2551 subject to specific conditions. The accredited verifier must retain full responsibility for the verification outcome and resulting report.
The accredited verifier must establish that any external organisation meets applicable independence and impartiality requirements, document outsourcing arrangements through an appropriate agreement and obtain operator consent. The accredited verifier cannot outsource independent review or drafting and issuing of the verification report.
Site visits and regional specialist networks
Installation visits are part of the CBAM verification regime. Under current rules for first-period verification, a physical site visit normally takes place by the accredited verification team; virtual visits and waivers are available only under prescribed conditions.
Verification organisations working across multiple countries must coordinate travel logistics such as site access plus technical interviews and inspections while maintaining consistent procedures and supervision levels. Logistical complexity increases when installations are geographically dispersed or involve technologies requiring specialist knowledge.
A regional network of qualified technical specialists could provide flexibility by supporting assignments within defined territories under an accredited verifier’s procedures and control. For south-eastern Europe coverage including Serbia and neighbouring markets such as Montenegro, Bosnia and Herzegovina, North Macedonia and Albania could be supported through regional teams.
Geographical proximity alone does not establish required competence because verifiers must assess technical knowledge familiarity with verification procedures and potential conflicts of interest. The objective is reliable access to qualified professionals rather than lower-cost staffing alone.
Independence constraints on consulting work
Impartiality is central because engineering companies may already provide services to operators whose emissions reports require verification. An engineering firm could help configure monitoring systems prepare emissions calculations develop reporting procedures or advise suppliers on CBAM compliance; participating in independent verification of similar work may create conflict risk.
The accreditation framework addresses relationships involving consultancy roles technical assistance common ownership shared management personnel financial interests or other circumstances that could compromise independence. Verification organisations must assess these risks before accepting assignments or engaging external personnel.
The distinction between supplier-side assistance and verifier-side technical support is fundamental in determining how work is performed within assurance processes. Separating employees within closely connected organisations does not necessarily eliminate conflicts because broader legal financial organisational relationships can still be relevant.
Sector-specific engineering needs: steel aluminium electricity
Steel-related assessments can require expertise across integrated steelworks operations including electric arc furnace contexts where process boundaries material inputs energy balances and production stages relate to reported figures. Downstream processing adds complexity when finished products incorporate purchased precursors carrying emissions information from upstream installations that must comply with CBAM requirements.
This can create potential sources of error across supply chains where production stages occur at separate facilities. Aluminium similarly requires specialised knowledge because smelting casting recycling and downstream processing may involve distinct monitoring systems calculation boundaries and allocation approaches between relevant goods.
Verification organisations may therefore need engineers capable of examining process equipment energy consumption intermediate materials and emissions allocation methods suited to specific technologies used at installations outside the EU. Such expertise can be valuable when teams have broad emissions-accounting capability but limited experience with particular production processes.
Electricity is described as one of the most technically specialised areas because it involves interconnected systems spanning generators network operators suppliers traders plus cross-border capacity arrangements. Where actual electricity emissions are claimed supporting evidence can extend beyond generating installation calculations into contractual relationships generating-unit characteristics metering systems network conditions hourly transmission arrangements plus relevant power purchase agreements.
External resources affect staffing models
The business model for CBAM verification may combine permanent audit teams with external specialists while balancing continuity procedural control institutional knowledge against flexibility across industries technologies countries assignment volumes geographical distribution industrial complexity and accreditation scope coverage.
An organisation handling recurring assignments for similar installations may justify maintaining permanent sector specialists; a verifier working across wider technology ranges may engage experts for defined tasks instead. Local specialists could be contracted for site investigations technical assessments or permitted activities under defined supervision arrangements within verifier procedures.
No universal pricing model is prescribed for these commercial arrangements under CBAM rules described in the source material. Commercial terms would need to reflect competence assignment complexity professional responsibilities independence requirements plus time needed to complete work while ensuring externally performed work meets quality standards comparable with internal tasks.
A continuing oversight role for accreditation bodies
The market is governed not only by initial accreditation but also continuing oversight by EU national accreditation bodies assessing accredited verifiers including their technical competence organisational arrangements compliance with accreditation requirements. Where activities are outsourced accreditation bodies may examine relevant arrangements at external organisation premises as part of oversight controls reinforcing verifier responsibility over outside resources.
Local engineering companies seeking recurring work with international verifiers may need management systems comparable with established assurance organisations including personnel competence records confidentiality procedures conflict-of-interest declarations technical working papers plus controlled document management practices used during assurance activities.
Separate services around CBAM reporting
The regulatory framework creates demand for several related but legally separate services described as supplier-side consulting plus readiness support for non-EU operators establishing monitoring procedures preparing emissions information identifying deficiencies before independent assessment; technical assurance for EU importers plus authorised declarants involving supplier-readiness assessments documentation coordination plus reporting potential compliance risks to European customers; technical support for accredited verification organisations where external experts contribute specialist knowledge or perform permitted activities under supervision; and formal accredited verification carried out by organisations holding required accreditation retaining full responsibility for reports issued under their scope.
Digital monitoring and evidence-management technologies could support preparation where facilities maintain reliable electronic records calibrated instruments plus controlled reporting procedures compared with fragmented manual spreadsheets used at some installations outside the EU described in the source material. Digitalisation does not remove independent assessment requirements because incorrect measurement boundaries or calculation methods can still be reproduced consistently through platforms while verifiers remain responsible for evaluating underlying evidence quality.
Serbia-focused capacity building for first cycles
The Western Balkans combine industrial production electricity generation engineering expertise plus established commercial links with EU markets; Serbia has engineering companies involved in industrial projects electrical infrastructure automation technical supervision environmental systems described as potential capabilities adaptable for CBAM-related work supporting international assurance organisations through local partners’ knowledge access to technical personnel plus experience coordinating with plant operators.
The opportunity is not restricted solely to Serbia because regional specialists able to work under international verification procedures could support assignments elsewhere in south-eastern Europe drawing on experience with power-generation assets industrial electrical systems manufacturing processes across neighbouring countries described as part of regional coverage needs tied to actual demand volumes capacity decisions on permanent staffing versus external specialist use during CBAM implementation planning.
First annual declaration cycle tests monitoring records
The first annual CBAM verification cycle will test whether non-EU installations have maintained adequate monitoring records whether accredited verifiers have sufficient qualified personnel capacity aligned with reporting timetables set out in Commission planning described earlier; it will also test coordination between operators technical specialists plus verification organisations responsible for completing documentary assessments installation visits completing assessments issuing formal reports through registry channels available from January 2027 described earlier; difficulties may arise where monitoring arrangements are incomplete precursor information is fragmented or complex production systems require additional investigation during assessment processes described in the source material.
