CBAM Reporting for Ukrainian Exporters in the 2026 Definitive Regime: Specific Embedded Emissions (SEE) Calculation, Precursors, Accredited Verification, and ISO 14001 Implementation

CBAM reporting for Ukrainian exporters under the EU's Carbon Border Adjustment Mechanism entered a fundamentally new phase on 1 January 2026. The two-year transitional learning period is over, and the Definitive Regime established by Regulation (EU) 2023/956 of the European Parliament and of the Council (with calculation rules anchored in Commission Implementing Regulation (EU) 2023/1773) is now in full legal force. Every tonne of covered iron and steel, aluminium, cement, mineral fertilisers, hydrogen, and electricity exported from Ukraine into the European Union now carries a direct financial carbon obligation tied to the European Union Emissions Trading System (EU ETS).

According to guidance published by the European Commission's Directorate-General for Taxation and Customs Union (DG TAXUD), CBAM prevents carbon leakage by equalizing the carbon price between domestic EU installations and non-EU producers. When European steelmakers, cement plants, and chemical producers pay 65 to 90+ EUR per tonne of $\text{CO}_2\text{e}$ under the EU ETS, EU importers purchasing goods from outside the bloc must purchase and surrender a corresponding number of CBAM certificates.

Splitting Legal Liability and Engineering Responsibility Between the EU Importer and Ukrainian Producer

Legally, the party responsible for customs clearance and certificate surrender inside the European Union is the Authorised CBAM Declarant (the EU buyer or an indirect customs representative). A Ukrainian manufacturer never buys CBAM certificates directly from Brussels. Yet that legal boundary doesn't insulate Ukrainian exporters at all: an EU importer in Germany, Poland, or Italy has no way of knowing how many cubic meters of natural gas, tonnes of metallurgical coke, megawatt-hours of grid electricity, or tonnes of ferroalloys your plant in Ukraine consumed to produce a specific shipment.

As a result, EU buyers push the engineering burden straight onto the Ukrainian producer through supply-chain contracts. Your customer requires a process-level Specific Embedded Emissions ($SEE_g$) calculation compiled in the official EU CBAM Communication Template and verified by an independent accredited verifier. If your plant can't supply verified actual emissions data, your EU buyer gets hit with punitive default values (country averages plus a regulatory mark-up) and will either deduct that extra carbon cost straight from your EXW/FCA invoice price or switch to a competing supplier whose numbers are verified.

Across dozens of industrial projects delivered by Ekontrol (Еконтроль), we've seen one hard truth: defensible CBAM emissions data cannot be improvised in a last-minute spreadsheet by the sales or accounting department. It requires sub-metered process boundaries, reconciled mass balances, accredited laboratory fuel testing, and a structured environmental management system, which we break down in our complete ISO 14001 certification guide.

Annex I to Regulation (EU) 2023/956 defines the exact scope of covered products by Combined Nomenclature (CN) codes (whose first 8 digits match Ukraine's UKTZED customs tariff classification). Six carbon-intensive sectors are covered, tracking three greenhouse gases: carbon dioxide ($\text{CO}_2$), nitrous oxide ($\text{N}_2\text{O}$ in nitric acid and fertiliser production), and perfluorocarbons ($\text{PFCs}$ generated during anode effects in primary aluminium smelting).

Simple Goods vs. Complex Goods and the Precursor Cascade

Under Implementing Regulation (EU) 2023/1773, all CBAM-covered goods fall into one of two engineering categories:

1. Simple goods: goods produced exclusively from raw input materials (iron ore, quarried limestone, clay, natural gas, water, air) and fuels that are defined under CBAM rules as having zero embedded emissions ($SEE = 0$) prior to entering the installation gate. Examples include cement clinker calcined from raw limestone, pig iron reduced from iron ore, Direct Reduced Iron (DRI), anhydrous ammonia, and primary unwrought aluminium.
2. Complex goods: goods whose production process consumes other CBAM-covered input materials that already carry embedded emissions from upstream installations. In CBAM engineering terminology, these upstream CBAM-covered inputs are called precursors.

Precursors represent the single biggest blind spot for Ukrainian downstream metal fabricators, pipe mills, wire-drawing plants, and fastener manufacturers. Suppose your factory doesn't operate a blast furnace or electric arc furnace; instead, you purchase hot-rolled steel coils or wire rod (CN 7208 / CN 7213) from a Ukrainian or foreign steel mill and cold-forge screws, bolts, and washers (CN 7318), weld structural steelwork (CN 7308), or draw seamless and welded steel tubes (CN 7304 - 7306). Your finished product is a complex CBAM good!

In downstream metal fabrication, the direct natural gas burned in your heat-treatment furnaces plus the indirect electricity consumed by your stamping presses and welding machines typically accounts for only 10-20% of the final product's Specific Embedded Emissions ($SEE_g$). The remaining 80-90% of the carbon footprint enters your gate embedded inside the rolled steel precursor. Consequently, you can't complete a valid CBAM calculation for your EU buyer without collecting verified $SEE_i$ precursor certificates from your upstream metal, clinker, or ammonia suppliers.

The table below maps all six CBAM sectors, their primary CN / UKTZED codes, tracked greenhouse gases, and mandatory precursor chains.

Between October 2023 and December 2025, CBAM ran in transitional mode: EU importers filed quarterly reports in the CBAM Transitional Registry without surrendering certificates or hiring external verifiers. On 1 January 2026, the mechanism transitioned into its Definitive Regime, introducing four strict enforcement gates for Ukrainian exporters.

Four Enforcement Shifts in the 2026 Definitive Regime

1. Customs Clearance Restricted to Authorised CBAM Declarants: starting 1 January 2026, EU customs authorities block the release for free circulation of CBAM goods (above the 50-tonne annual de minimis threshold) unless the importer holds valid Authorised CBAM Declarant status in the EU CBAM Registry. For a full timeline of these regulatory milestones, see our briefing on CBAM in 2026: what the definitive regime changes.
2. Mandatory Third-Party Verification of Actual Emissions (Articles 8 & 18 of Regulation (EU) 2023/956): unverified self-declarations signed solely by a plant manager are no longer accepted to substantiate actual emissions in an annual CBAM declaration. Your installation's Specific Embedded Emissions ($SEE_g$) report must be verified in accordance with EN ISO 14064-3 by an independent verification body accredited under EN ISO/IEC 17029 and ISO 14065 by a National Accreditation Body belonging to the European co-operation for Accreditation (EA MLA) (in Ukraine, the national EA MLA signatory is the National Accreditation Agency of Ukraine - NAAU).
3. Strict Phase-Out of Uncapped Default Values and Punitive Mark-Ups: during the early quarters of the transitional phase (late 2023 to mid-2024), producers could rely entirely on European Commission global average default tables. Since July 2024, the use of estimations for complex goods has been capped at 20% of total embedded emissions. Under the 2026 Definitive Regime, if a Ukrainian producer fails to supply an accredited verification report for its actual emissions, the EU declarant must apply country-specific default values increased by a proportionate punitive mark-up (or fallback values based on the 10% worst-performing EU ETS installations). Because historical baseline averages for Ukraine's grid and heavy industry reflect older coal- and open-hearth-era assets, falling back on default values inflates the carbon bill of modernized Ukrainian electric-arc steel, downstream metalware, or dry-kiln cement plants by 25% to 60%.
4. Direct Installation Registration in the EU CBAM Operators Portal (Article 10): under Article 10 of Regulation (EU) 2023/956, Ukrainian installation operators can register their production sites directly inside the European Commission's central CBAM Registry (Operators Portal). Once registered, you upload your verified annual installation emissions report once and share verified $SEE_g$ figures directly with multiple Authorised CBAM Declarants across the EU without exposing proprietary cost breakdowns to intermediaries.

Through the Omnibus I simplification package (Regulation (EU) 2025/2083) adopted in autumn 2025, the EU replaced the old 150 EUR per-consignment exemption with a mass-based de minimis threshold of 50 tonnes per calendar year.

How the 50-Tonne Rule Works and Why Most Industrial Exporters Remain in Scope

Under Regulation (EU) 2025/2083, an EU importer whose cumulative annual imports across the four mass-based CBAM sectors (iron and steel, aluminium, cement, and fertilisers combined) remain below 50 tonnes of net mass per calendar year is exempt from Authorised CBAM Declarant registration, annual reporting, and certificate surrender. The 50-tonne exemption never applies to electricity or hydrogen.

Ukrainian suppliers must watch out for a frequent miscalculation here:

• The 50-tonne threshold is aggregated on the EU importer's side across all non-EU suppliers worldwide, not per Ukrainian factory! Suppose your machine-building shop in Ukraine exports only 28 tonnes of steel brackets (CN 7308) per year to a German industrial distributor. If that German buyer also imports 18 tonnes of steel fasteners from Turkey and 12 tonnes of aluminium profiles from China, their cumulative annual CBAM import mass is $28 + 18 + 12 = 58\text{ tonnes} > 50\text{ tonnes}$. Because the buyer crosses the 50-tonne threshold, 100% of their imports (including your 28 tonnes) fall under full CBAM obligations, and they'll demand verified $SEE_g$ figures from your plant.

CBAM Certificate Pricing and the EU ETS Free Allocation Phase-Out (2026 - 2034)

Each CBAM certificate corresponds to $1\text{ tonne of CO}_2\text{e}$ embedded in imported goods and is priced at the average auction closing price of EU ETS allowances (calculated as a quarterly average in 2026 and a weekly average from 2027 onward). To mirror the gradual phase-out of free EU ETS allowances granted to European manufacturers, the financial obligation scales up via the CBAM Factor (Article 31 of Regulation (EU) 2023/956):

• 2026: $2.5%$ of the EU ETS benchmark emissions are subject to certificate surrender ($97.5%$ free allocation deduction);
• 2027: $5.0%$;
• 2028: $10.0%$;
• 2029: $22.5%$;
• 2030: $48.5%$;
• 2031 - 2033: steps up from $61%$ to $86%$;
• 2034: $100%$ full carbon pricing with zero free allocation deduction.

Here's the engineering catch: the free allocation deduction is calculated against the EU ETS product benchmark (representing the top 10% most carbon-efficient installations in Europe), not against a percentage of your actual emissions. Any emissions above the strict EU ETS benchmark are exposed to the carbon price immediately from 2026!

Calculating Specific Embedded Emissions ($SEE_g$) under Annex IV of Regulation (EU) 2023/956 and Implementing Regulation (EU) 2023/1773 differs fundamentally from corporate footprint accounting under the GHG Protocol Corporate Standard or ISO 14064-1. While a corporate inventory aggregates total Scope 1, Scope 2, and Scope 3 emissions across an entire legal entity (including administrative offices and company vehicles), CBAM draws strict system boundaries around functional Production Processes inside a stationary industrial installation.

Step 1. Defining System Boundaries and Production Process Routes

If your plant manufactures both CBAM goods (such as steel pipes or welded structures) and non-CBAM goods (such as machined cast-iron housings or painted agricultural implements) under the same roof, you cannot divide total utility bills by total factory tonnage. Engineers must partition the installation into discrete Production Processes correlated to CN aggregated goods categories and specific production routes (for example, Blast Furnace / Basic Oxygen Furnace BF-BOF steelmaking vs. Electric Arc Furnace EAF route; dry-process vs. wet-process clinker kilns) and isolate the Attributed Emissions ($ ext{AttrEm}$) for each process.

Step 2. Calculating Attributed Direct Emissions ($ ext{AttrEm}_{\text{Dir}}$)

For a given production process over the reporting period, Attributed Direct Emissions ($ ext{AttrEm}_{\text{Dir}}$, in $\text{t CO}_2\text{e}$) are governed by the process energy and mass balance equation:

$$\text{AttrEm}{\text{Dir}} = \text{DirEm}^* + \text{Em}{\text{H,imp}} - \text{Em}{\text{H,exp}} + \text{Em}{\text{WG}}$$

Where:

• $\text{DirEm}^*$ represents directly attributable emissions from fuel and material source streams inside the production process boundary;
• $\text{Em}{\text{H,imp}}$ and $\text{Em}{\text{H,exp}}$ represent emissions associated with measurable heat (steam or hot water in TJ or Gcal) imported into or exported out of the production process;
• $\text{Em}_{\text{WG}}$ accounts for emissions linked to exported or imported waste gases (blast furnace gas, coke oven gas, or converter gas).

Under Implementing Regulation (EU) 2023/1773, installation operators determine $\text{DirEm}^*$ using one of two approved engineering methodologies:

1. Calculation-Based Methodology (Standard Method and Mass-Balance Method):
   • Combustion emissions (Standard Method): fuel activity data ($AD_k$, in tonnes or $10^3\text{ Nm}^3$) is multiplied by Net Calorific Value ($NCV_k$, in $\text{TJ/t}$), the emission factor ($EF_k$, in $\text{t CO}2/\text{TJ}$), and the oxidation factor ($OF_k$): $$E{\text{comb}} = \sum_{k} \left( AD_k \cdot NCV_k \cdot EF_k \cdot OF_k \right)$$
   • Process emissions and Mass-Balance Method: chemical decomposition of carbonates (such as limestone calcination $\text{CaCO}3 \to \text{CaO} + \text{CO}2$ in cement kilns or lime shaft furnaces) or carbon oxidation across metallurgical inputs (coke, coal, graphite electrodes, scrap, pig iron, ferroalloys) minus carbon sequestered in output steel or slag, multiplied by the stoichiometric ratio of $\text{CO}2$ to carbon ($44.01 / 12.011 = 3.664$): $$E{\text{mb}} = 3.664 \cdot \sum{m} \left( AD_m \cdot f{C,m} \right)$$ where $f_{C,m}$ is the laboratory-determined mass fraction of carbon ($\text{t C/t}$) in input stream $m$ (positive sign) or output product/waste stream (negative sign).
2. Measurement-Based Methodology (CEMS): continuous measurement of greenhouse gas concentration ($\text{CO}_2, \text{N}_2\text{O}$) and volumetric flue-gas flow rate in the stack using calibrated Continuous Emission Monitoring Systems (CEMS) meeting EN 14181 quality assurance levels (QAL1, QAL2, QAL3, and AST).

Step 3. Calculating Attributed Indirect Emissions ($ ext{AttrEm}_{\text{Indir}}$)

Attributed Indirect Emissions capture the carbon footprint of electrical energy consumed by process machinery (arc furnaces, rolling mills, grinding mills, extruders, compressors):

$$\text{AttrEm}{\text{Indir}} = E{\text{el,cons}} \times EF_{\text{el}}$$

Where $E_{\text{el,cons}}$ is sub-metered electricity consumption (in $\text{MWh}$) inside the process boundary and $EF_{\text{el}}$ is the electricity emission factor ($\text{t CO}_2/\text{MWh}$). Under Annex IV of Regulation (EU) 2023/956, grid electricity is multiplied by the European Commission's default country grid emission factor unless the producer proves either a direct technical link to a power generation source (such as an on-site solar array or CHP plant) or a valid Power Purchase Agreement (PPA) meeting strict temporal and grid-congestion rules.

Step 4. The Master Equation for Specific Embedded Emissions ($SEE_g$) Including Precursors

Combining the installation's own attributed emissions ($ ext{AttrEm}_g$) with the embedded emissions carried by all consumed precursors ($M_i$ and $SEE_i$) yields the Specific Embedded Emissions of complex good $g$ ($SEE_g$, expressed in $\text{t CO}_2\text{e}$ per tonne of output):

$$SEE_g = \frac{\text{AttrEm}g + \sum{i} \left( M_i \cdot SEE_i \right)}{AL_g}$$

Where:

• $AL_g$ (Activity Level) is the net mass (in tonnes) of CBAM good $g$ produced during the reporting period ($SEE_{g,\text{Dir}}$ and $SEE_{g,\text{Indir}}$ are reported separately and summed);
• $M_i$ is the total mass (in tonnes) of precursor $i$ consumed in the production process to manufacture $AL_g$ (including gross material input before cutting scrap losses);
• $SEE_i$ is the verified Specific Embedded Emissions ($\text{t CO}_2\text{e/t}$) of precursor $i$ supplied by the upstream producer.

Worked Engineering Calculation for a Ukrainian Structural Steel Exporter (CN 7308)

Consider a Ukrainian steel fabrication plant that produced $AL_g = 10,000\text{ t}$ of welded structural steel trusses and columns (CN 7308 90) over the 2026 reporting year:

1. Consumed Precursor ($i = 1$): to fabricate $10,000\text{ t}$ of finished structures, the shop consumed $M_1 = 10,550\text{ t}$ of hot-rolled steel plates and sections (CN 7208 / 7216), with $550\text{ t}$ becoming off-cut scrap. The upstream steel mill provided a verified CBAM Communication Template showing $SEE_{1,\text{Dir}} = 1.82\text{ t CO}2\text{e/t}$ and $SEE{1,\text{Indir}} = 0.28\text{ t CO}_2\text{e/t}$ (total $SEE_1 = 2.10\text{ t CO}2\text{e/t}$). Precursor embedded emissions equal: $$\text{Em}{\text{prec,Dir}} = 10,550 \times 1.82 = 19,201\text{ t CO}2\text{e}, \quad \text{Em}{\text{prec,Indir}} = 10,550 \times 0.28 = 2,954\text{ t CO}_2\text{e}$$
2. Installation Direct Emissions ($ ext{AttrEm}_{g,\text{Dir}}$): preheating furnaces, paint-curing ovens, and oxy-fuel cutting torches burned $180,000\text{ Nm}^3$ of natural gas ($NCV = 0.0342\text{ TJ}/10^3\text{ Nm}^3$, $EF = 56.1\text{ t CO}_2/\text{TJ}$, $OF = 1.0$, yielding $345\text{ t CO}_2$), while $\text{CO}_2$-based MAG welding shielding gas and welding wire oxidation added $35\text{ t CO}2$. Total $\text{AttrEm}{g,\text{Dir}} = 380\text{ t CO}_2\text{e}$.
3. Installation Indirect Emissions ($ ext{AttrEm}_{g,\text{Indir}}$): CNC plasma cutters, welding rectifiers, shot-blasting turbines, and overhead cranes consumed $E_{\text{el,cons}} = 1,900\text{ MWh}$ of electricity (at a grid factor of $EF_{\text{el}} = 0.43\text{ t CO}2/\text{MWh}$), yielding $\text{AttrEm}{g,\text{Indir}} = 1,900 \times 0.43 = 817\text{ t CO}_2\text{e}$.
4. Final Specific Embedded Emissions ($SEE_g$): $$SEE_{g,\text{Dir}} = \frac{380 + 19,201}{10,000} = 1.9581\text{ t CO}2\text{e/t}, \quad SEE{g,\text{Indir}} = \frac{817 + 2,954}{10,000} = 0.3771\text{ t CO}2\text{e/t}$$ $$SEE{g,\text{Total}} = 1.9581 + 0.3771 = 2.3352\text{ t CO}_2\text{e per tonne of finished steel structures}$$

Notice what the math reveals: 94.9% of direct embedded emissions came from the rolled steel precursor rather than the fabrication plant's own gas meters. Controlling precursor documentation across your procurement chain is therefore just as important as metering your own furnaces.

To pass mandatory third-party verification under the 2026 Definitive Regime and provide EU buyers with legally defensible numbers, a Ukrainian producer must maintain two core engineering deliverables: internal Monitoring Methodology Documentation (MMD) and the standardized EU CBAM Communication Template for Installations.

1. Engineering Structure of the Monitoring Methodology Documentation (MMD)

The MMD is your installation's written rulebook for carbon accounting and the very first document an accredited verifier inspects under EN ISO 14064-3. In accordance with Implementing Regulation (EU) 2023/1773, a compliant MMD contains:

• Complete Installation Identification: official English name, UN/LOCODE of the Ukrainian municipality, exact GPS coordinates (latitude and longitude to 5-6 decimal places), and a site plot plan showing physical installation boundaries;
• Process Flow Diagrams (PFD) and System Boundaries: engineering schematics mapping every CBAM production process, fuel and material source streams, precursor entry points, measurable heat meters, electricity sub-meters, and finished product weighing points ($AL_g$);
• Metrology Register and Data Control System: an inventory of commercial and technical gas flow meters, belt weighers, truck scales, and electricity meters specifying accuracy classes, calibration intervals, uncertainty calculations, and conservative data-gap substitution procedures;
• Sampling and Laboratory Analysis Procedures: protocols governing how batch samples of coal, coke, scrap, limestone, ferroalloys, and natural gas are sampled and analyzed for carbon fraction ($f_C$) and Net Calorific Value ($NCV$).

2. What Accredited Verifiers Check During an On-Site CBAM Audit

When an independent verifier accredited under ISO 14065 / EN ISO/IEC 17029 by an EA MLA signatory (such as NAAU in Ukraine or an EU national accreditation body) audits your 2026 installation report, they test for reasonable assurance against a strict 5% materiality threshold per CN code:

• cross-checking natural gas, coal, and electricity volumes reported in your CBAM calculation against utility fiscal invoices, automated commercial metering logs (ASKOE), and ERP general ledger inventory accounts;
• reconciling your production mass balance: verifying that raw precursor tonnage ($M_i$) minus documented scrap and scale loss equals net finished output ($AL_g$) plus warehouse stock changes;
• inspecting physical calibration seals on scales and flow meters directly on the shop floor.

An accredited verifier will refuse to issue a positive Verification Report if your $SEE_g$ calculation lives in an unvalidated Excel file on one engineer's laptop with no document control, no internal audit trail, and uncalibrated meters. That's why export-oriented Ukrainian manufacturers anchor their CBAM Monitoring Methodology Documentation (MMD) inside four internationally recognized standards.

Four Standards That Make CBAM Emissions Data Audit-Proof

1. Environmental Management System under ISO 14001 (DSTU ISO 14001:2015): provides the governance architecture required by EU verifiers. Under Clause 6.1.2 (Environmental aspects), your plant maps all stationary greenhouse gas emission sources; Clause 6.1.3 (Compliance obligations) tracks Regulation (EU) 2023/956 updates; Clause 7.5 enforces tamper-proof retention of primary utility and production records for the mandatory 4-year CBAM audit window; and Clause 9.2 (Internal audit) catches calculation or boundary errors before the external verifier arrives.
2. Energy Management System under ISO 50001 (DSTU ISO 50001:2020): solves the hardest engineering challenge in CBAM, namely splitting shared natural gas, steam ($\text{Em}{\text{H,imp/exp}}$), and electricity ($E{\text{el,cons}}$) between CBAM production processes and non-CBAM workshops. By establishing Significant Energy Uses (SEUs), Energy Baselines (EnB), and process-specific Energy Performance Indicators (EnPIs in $\text{kWh/t}$ or $\text{Nm}^3\text{ gas/t}$), as detailed in our ISO 50001 energy management guide, you isolate non-CBAM energy loads and legally lower your product's $SEE_g$ by 8-22%.
3. Laboratory Competence under ISO/IEC 17025 (DSTU EN ISO/IEC 17025:2019): under Implementing Regulation (EU) 2023/1773 and EU ETS monitoring rules, calculation factors derived from chemical analysis, including the carbon content ($f_C$) of coke, coal, electrodes, ferroalloys, and scrap, the carbonate content ($\text{CaCO}_3 / \text{MgCO}_3$) of limestone and clay, and the Net Calorific Value ($NCV$) of fuels, must be determined by a laboratory accredited to EN ISO/IEC 17025 with documented measurement uncertainty (see our guide to measurement uncertainty and calibration under ISO/IEC 17025). Ekontrol provides turnkey consulting for ISO/IEC 17025 laboratory accreditation.
4. Biomass Sustainability under ISCC (ISCC EU / ISCC PLUS) and Traceability under ISO 9001: many Ukrainian cement kilns, lime plants, and metallurgical furnaces co-fire solid biomass (sunflower husk pellets, wood chips, or biogenic RDF) to cut fossil fuel emissions. Under CBAM rules aligned with the EU Renewable Energy Directive (RED II / RED III), you may assign a zero emission factor ($EF_{\text{biogenic}} = 0$) to combusted biomass only if the biofuel meets strict sustainability and GHG savings criteria verified via an approved scheme such as ISCC. Meanwhile, batch traceability under ISO 9001 links every exported lot back to the exact heat or batch number of its input precursors ($M_i$).

Ukrainian heavy industry holds a valuable structural advantage: since 2021, Ukraine has enforced Law No. 377-IX "On the Principles of Monitoring, Reporting and Verification of Greenhouse Gas Emissions" (along with CMU Resolutions No. 960 and No. 959), which mirrors EU ETS Monitoring and Reporting Regulation (EU) 2018/2066. Operators of Ukrainian blast furnaces, electric-arc steel mills, sinter plants, coke ovens, cement kilns, lime kilns, and ammonia plants already maintain registered Monitoring Plans and undergo annual verification by verifiers accredited by NAAU.

Four Engineering Adjustments Required to Convert Ukrainian MRV Data Into a CBAM Report

Even if your facility already files verified reports under Ukraine's national MRV law, you can't simply attach your Ukrainian Operator's Report to an EU buyer's questionnaire. Ekontrol engineers bridge four technical gaps between national MRV and EU CBAM:

1. Splitting Installation Totals Into Product-Specific $SEE_g$ by CN Code: Ukrainian MRV outputs a single facility-wide direct emissions figure for the calendar year (for example, $420,000\text{ t CO}_2$ for the entire integrated plant). CBAM requires partitioning that installation into separate production processes and computing specific embedded emissions per tonne of each individual CN code (pig iron vs. crude steel vs. hot-rolled coil vs. pipes).
2. Adding Process-Attributed Indirect Emissions ($\text{AttrEm}_{\text{Indir}}$): Ukraine's national MRV system covers only direct emissions from fuel combustion and technological reactions. CBAM mandates tracking and attributing electricity consumption ($\text{MWh/t}$) across every production process.
3. Incorporating Upstream Precursor Emissions ($\sum M_i \cdot SEE_i$): under national MRV, purchased steel billets, ferroalloys, or clinker brought in from another company carry zero emissions inside your installation report. Under CBAM, the embedded emissions of all consumed precursors must be added into the numerator of your $SEE_g$ equation.
4. Covering Downstream Fabricators Outside National MRV Scope: manufacturers of structural steelwork (CN 7308), fasteners (CN 7318), wire products (CN 7317), or extruded aluminium profiles (CN 7604) whose boiler thermal input sits below $20\text{ MW}$ aren't covered by Law No. 377-IX at all, yet 100% of their EU exports fall under CBAM. These plants must build their Monitoring Methodology Documentation (MMD) from the ground up.

Because primary fuel, electricity, and precursor mass-balance records for the 2026 calendar year accumulate every single day and cannot be reconstructed retroactively when your EU buyer prepares their annual declaration in 2027, Ekontrol recommends a five-step engineering roadmap:

1. Step 1. Customs CN Code and Precursor Chain Audit: extract all 8-digit CN / UKTZED codes from your export customs declarations, match them against Annex I to Regulation (EU) 2023/956, and map every raw material or semi-finished input that qualifies as a CBAM precursor.
2. Step 2. On-Site Emissions & Energy Diagnostic Gap Audit: Ekontrol engineers inspect your production lines, evaluate gas, steam, electricity, and weighing meter locations and calibration status, and identify gaps between your current accounting and Implementing Regulation (EU) 2023/1773.
3. Step 3. Engineering the Monitoring Methodology Documentation (MMD) and Implementing ISO 14001 & ISO 50001: we define your installation and production process boundaries, set up calculation models for $\text{AttrEm}{\text{Dir}}$, $\text{AttrEm}{\text{Indir}}$, and precursor cascades ($SEE_g$), coordinate fuel/raw-material testing with ISO/IEC 17025 accredited laboratories, and integrate data governance into turnkey management system implementation (ISO 14001, ISO 50001, ISO 9001, and ISCC).
4. Step 4. Populating the EU CBAM Communication Template & Operators Portal Registration: we calculate your actual Specific Embedded Emissions ($SEE_g$) per CN code, prepare English-language reporting packages for your Authorised CBAM Declarants, and assist with registering your installation in the European Commission's Operators Portal under Article 10.
5. Step 5. Turnkey Verification and Certification Audit Support: we compile the complete evidence binder (energy balances, ERP mass-balance ledgers, metrological calibration certificates, laboratory protocols) and support your engineering team throughout third-party verification under EN ISO 14064-3 and management system certification.
