Serbian manufacturers preparing for the EU’s Carbon Border Adjustment Mechanism (CBAM) can organise compliance and verification readiness around five work packages covering product classification, factory measurement, external data, ongoing monitoring and verification preparation. The approach provides a staged alternative to inaction or a large-scale digital-transformation programme.
- 1. Product classification and facility assessment
- 2. Metering design and systems integration
- 3. Electricity and precursor evidence
- 4. Monthly monitoring, reporting and verification operations
- 5. Independent verification preparation
- Programme governance and investment priorities
- Training and staged expansion across export portfolios
The framework follows the emissions evidence chain, connecting exported products with their production processes, energy consumption, precursor materials and supporting records. Its sequence is important because installing additional meters before defining reporting boundaries can increase costs without resolving the most significant evidence gaps.
1. Product classification and facility assessment
The first work package establishes which products and production processes require reporting. The team builds a matrix connecting exported product codes and Combined Nomenclature (CN) classifications with manufacturing routes, relevant emissions sources and precursor materials.
The assessment distinguishes goods covered by CBAM from customer requests based on other methodologies. Defining this scope helps factories direct investment towards information that has a clear reporting purpose. Each work package should have a measurable acceptance criterion. For product assessment, completion means that all priority exports have been mapped to their respective production routes.
2. Metering design and systems integration
The second package addresses the factory’s measurement infrastructure. Engineers examine electrical single-line diagrams, fuel and heat measurements, on-site generation, process meters and production systems to determine where existing instrumentation is sufficient and where additional equipment is justified.
The design establishes a measurement hierarchy and specifies system interfaces, timestamp conventions, data-retention requirements and quality flags. These controls allow energy records to be reconciled with production data. Metering acceptance can be measured by whether relevant balances close within agreed tolerances. The objective is not to install sensors on every motor, but to obtain sufficient evidence for the emissions results that matter.
3. Electricity and precursor evidence
The third package covers information held outside the factory. Electricity suppliers, renewable generators, material producers and traders may control records that the manufacturer cannot generate internally. Procurement agreements should therefore address access to generator records, environmental-attribute documentation, producing-installation identities, precursor emissions data and verification references. The work package must account for data-access rights alongside the physical supply arrangements.
Investment priorities depend on materiality. Where a furnace accounts for most fuel emissions, measurement resources may need to focus on that equipment. Where precursor emissions dominate the calculation, supplier documentation and material traceability may require more attention than sub-metering smaller electrical loads. The package is complete when the required material-data coverage reaches its target. Supplier negotiations may need to begin early because contractual changes and evidence requests can take time.
4. Monthly monitoring, reporting and verification operations
The fourth package establishes an ongoing monitoring, reporting and verification (MRV) process. Monthly routines reconcile energy consumption, materials and production, update applicable factors, record exceptions, review manual corrections and calculate product results under the relevant methodologies.
Management receives a defined set of indicators covering energy intensity, renewable-electricity qualification, precursor-data coverage and unresolved evidence gaps. These indicators help identify problems before missing records or inconsistent calculations accumulate. Completion requires a monthly reporting cycle that can be reproduced using the underlying records. The factory must be able to demonstrate how source data were converted into the reported product result.
5. Independent verification preparation
The fifth package tests whether the monitoring plan reflects actual factory practice. Sample calculations are reconstructed from original evidence, and an indexed data room is assembled for review.
Staff are prepared for site visits, while findings are assigned to the responsible departments. The accredited verifier retains independence; the factory-side team supports the process by ensuring that requested information and responses are complete and timely. Verification preparation is complete when sample data can be traced through the evidence chain from the original source to the resulting calculation.
Programme governance and investment priorities
Although the five packages follow a sequence, work can overlap. Supplier evidence requests can begin while the product matrix is being refined, and meter upgrades can proceed alongside scope assessment. A pilot covering one product family can test the approach before it is extended across the plant.
Governance must apply across all five packages. The plant operator should own the monitoring data and report, engineering advisers should design controls, IT integrators should implement interfaces, and accredited verifiers should provide independent conclusions. Responsibilities must be documented so that no participant is asked to verify its own advisory work.
The framework also gives management a basis for controlling budgets. Resources can be directed towards the most significant reporting risks rather than distributed evenly across every possible measurement point.
A programme dashboard can track each package’s scope, cost, owner, deadline and verification impact. It can show, for example, when a delayed procurement clause is preventing a product report from being completed, or when an agreed alternative allocation method means a planned meter installation is no longer the main priority. Budget approvals can be tied to demonstrated progress. Management can authorise the next phase once the preceding capability has met its acceptance criteria, reducing the risk of committing to extensive technology spending before the underlying product classifications and evidence requirements have been settled.
Training and staged expansion across export portfolios
The programme also requires staff training across departments. Procurement teams need to recognise evidence clauses, production personnel must preserve meter and batch records, sales teams need to understand methodology labels, and IT teams must maintain data lineage. These responsibilities make verification readiness an organisational capability rather than a task that can be completed by one technical department. Strong controls in one work package cannot compensate for missing records or misunderstood responsibilities elsewhere in the factory.
Expansion should follow the materiality of the export portfolio. Once the pilot covers product families responsible for most EU revenue or emissions exposure, the factory can extend the framework to lower-risk products using simplified controls. This staged approach allows Serbian exporters to prioritise major electricity and precursor-data gaps before allocating resources to marginal products, while management can monitor progress through defined deliverables and acceptance tests.
