Industrial exporters in the Western Balkans can build a functioning monitoring, reporting and verification (MRV) framework within 90 days for EU Carbon Border Adjustment Mechanism (CBAM) emissions evidence. The approach focuses on preserving historical data, selecting one representative production route, and assembling documentation needed for emissions calculations. The CBAM regime has applied since 1 January 2026, with the first annual declarations covering 2026 imports due by 30 September 2027.
Reliable production evidence is treated as the immediate priority for factories preparing for the reporting cycle. Companies are expected to preserve electricity measurements, fuel records, material traceability information and relevant renewable generation data. Where historical measurements were not recorded or retained, reconstructing the required information during later verification may be difficult or impossible.
A targeted three-month programme is presented as an alternative to implementing a complete industrial digitalisation project before addressing reporting requirements. The structure is intended to help manufacturers identify weaknesses, test existing systems against actual production data, and set investment priorities for subsequent improvements.
Selecting a representative product route for MRV testing
The effectiveness of a short-term implementation programme depends partly on choosing a representative product for initial assessment. A factory is expected to prioritise a product family with meaningful EU export sales and sufficient technical complexity to test energy measurements, material inputs and customer reporting needs.
Choosing the simplest manufacturing route may not expose weaknesses in monitoring systems. Selecting the most complex production process can also create excessive workload before basic procedures are established.
A medium-complexity production route is described as a practical basis for assessing the reporting architecture before expanding to additional goods or manufacturing facilities. The programme is set up with defined scope and assigned responsibilities, alongside an initial review of records already available inside the factory.
First phase: reporting boundaries and historical evidence retention
The first 30 days concentrate on product classification, evidence collection and identifying gaps in existing records. Engineering and reporting teams map exported products to their Combined Nomenclature (CN) codes, manufacturing routes, relevant emissions sources and precursor materials.
The initial assessment determines which information is required for the applicable emissions calculation and identifies physical production processes contributing to reported results. Engineers compile electrical diagrams, meter registers, fuel-consumption documentation and on-site electricity generation records, while procurement collects power supply agreements, raw-material contracts and emissions information received from suppliers.
Findings are recorded in an initial evidence-gap register, with the objective at this stage focused on identifying missing information and unresolved technical requirements rather than correcting every deficiency immediately.
Preserving 2026 electricity and production records
Preserving original 2026 production and energy data is treated as a separate priority during the first month. Raw electricity meter exports, manufacturing reports and inventory records are transferred into controlled storage while retaining consistent timestamps and the information needed to interpret historical measurements.
Attention is highlighted where industrial software platforms automatically overwrite short-interval measurements after limited retention periods. Factories may need to modify data-retention settings to preserve hourly or sub-hourly electricity information required for subsequent reconciliation and reporting.
These steps are intended to protect evidence generated during factory operations even where final emissions calculations and independent verification occur later.
Second phase: reconstructing product-level emissions calculations
The second phase tests whether factory information can be converted into a reproducible product-level emissions calculation. The implementation team selects one complete month of production and traces relevant electricity, fuel and material inputs through to finished manufacturing output.
Electricity and fuel balances are reconciled against original measurements and production activity. Relevant precursor batches are traced through procurement and inventory records, while allocation methods for shared utilities are documented.
The factory then calculates emissions figures required under the selected methodology, recording any estimates, assumptions or unavailable source information. The exercise is used to check whether production records and measurement systems support consistent calculation without relying on undocumented manual adjustments.
Supplier documentation and customer CBAM data needs
During the second month, external inputs needed for emissions calculations are also reviewed. Electricity suppliers and renewable generators may be asked to provide generating-installation records and evidence concerning electricity delivery.
Material suppliers can be requested to identify relevant producing installations and supply verified precursor emissions information where required by the calculation methodology. The commercial team is expected to determine whether individual EU customers require CBAM embedded emissions data, product carbon footprint information or both.
If procurement agreements do not guarantee access to necessary documentation, deficiencies can be addressed through contractual amendments or revised specifications for future tenders. These activities can begin before the end of the second phase because obtaining supplier information and negotiating data-access rights may require additional time.
Final phase: monthly controls and mock verification readiness
The final month converts the pilot calculation into a repeatable monitoring and reporting process. Emissions calculation files receive version controls, approval responsibilities are assigned, and an exception register is introduced to track unresolved data problems.
A mock verification exercise is conducted by selecting reported values and tracing them backwards through the calculation methodology to original production, energy and material records. Findings are prioritised according to significance for the emissions result, including deficiencies involving substantial material inputs or energy consumption.
Management receives an initial performance dashboard showing what proportion of reported information is supported by measured and independently verified data versus default values or estimates. The assessment also identifies which parts of the evidence chain function effectively and which require additional technical, contractual or organisational controls.
Residual risks, documentation templates, and next implementation steps
The pilot’s findings are used as a basis for developing an investment programme tied to actual reporting deficiencies. Potential measures include additional metering equipment, software interfaces, supplier-data arrangements and improved warehouse traceability systems.
Not every factory requires extensive new instrumentation; some may already have adequate measuring equipment but lack documented calculation procedures or effective data governance. Other installations may need substantial investment in sub-metering or systems capable of tracing precursor materials through production.
A verification calendar can be built around the 2027 deadline by planning engagement with accredited verifiers, potential site visits, supplier-documentation deadlines and customer submission dates backward from the EU importer’s annual declaration timetable. Standardised documentation for subsequent reporting periods can also be produced, including a supplier emissions-data request template, meter register, product-classification matrix, monthly reconciliation package, exception log and evidence-room index.
At programme end, unresolved deficiencies are consolidated into a quantified residual-risk register linked to affected products. Each issue can be associated with potential commercial or financial consequences, estimated corrective costs and a resolution deadline; this distinguishes items requiring correction before verification from those that may be addressed through permitted default values or conservative reporting treatment.
The programme also provides operational information for estimating ongoing workload and cost of maintaining MRV processes. A final management review evaluates completed pilot results, outstanding evidence gaps and proposed measures needed to extend the system over a further six- to twelve-month implementation plan covering accredited verifier engagement, procurement contract amendments, metering improvements and integration of industrial information systems.
