Steel processors in the Western Balkans are assessing their exposure under the EU Carbon Border Adjustment Mechanism (CBAM) with a focus on emissions embedded in covered iron and steel products. For many of these products, the carbon intensity of purchased precursor materials and how efficiently those inputs are converted into finished goods can affect reported embedded emissions more than electricity used in downstream processing.
Companies investing in rooftop solar installations or renewable electricity procurement may lower operating costs and improve broader product carbon footprints. The source material notes, however, that such improvements do not necessarily target the largest emissions components recognised under the current CBAM methodology for iron and steel.
Yield and precursor inputs shape embedded emissions per tonne
For rolling, drawing, cutting, machining and steel fabrication activities, the assessment is described as extending beyond factory energy consumption. It includes upstream production routes, verified precursor emissions and material yield, which influence both manufacturing costs and the carbon intensity allocated to saleable steel products.
The source states that when a processor consumes 1,000 tonnes of steel precursor material but produces 900 tonnes of saleable output, emissions linked to the input material are distributed across a smaller quantity of finished goods. It also says scrap generated during processing may retain commercial value and can sometimes be recycled, but the calculation must account for material quantities entering the relevant production process according to the prescribed methodology.
Yield is described as particularly important for steel service centres and fabrication facilities where cutting, slitting, stamping and machining can generate substantial offcuts. The source adds that measuring electricity consumption per tonne of finished product alone does not capture this relationship.
Manufacturers are said to need additional measurements covering tonnes of precursor consumed per tonne of saleable output. The same approach includes production yield, scrap quantities and associated scrap revenue to reflect how embedded emissions are allocated.
Traceability requirements for CBAM data quality
The origin of purchased steel is presented as another major component in the emissions calculation. Processors buying coils, billets, slabs and other steel inputs are described as needing information beyond material grade and beyond identifying only the trading company.
Where actual emissions values are used, records should identify the original producing installation and provide corresponding verified emissions information required under the applicable CBAM methodology. The source notes that this can be difficult when materials are purchased through intermediaries that do not maintain or disclose installation-level carbon data.
A factory may buy steel made through a relatively efficient production route but still be unable to demonstrate that advantage without supporting emissions records. In that case, the calculation may rely on less favourable information, reducing any commercial benefit from sourcing lower-emission materials.
Regulatory treatment depends on CN codes and process boundaries
The CBAM treatment of processed steel is described as depending on how exported goods are classified and on which production activities are involved. The source says Combined Nomenclature (CN) codes, production routes and applicable process boundaries determine which emissions sources and precursor materials contribute to reported results.
Under the definitive-period methodology referenced in the source material, many downstream finishing operations are treated differently from core iron and steel manufacturing processes. It also states that emissions associated with relevant upstream precursors can remain embedded in the finished covered product even when downstream operations contribute relatively limited direct emissions.
Manufacturers using multiple production routes are described as needing to identify inputs and emissions components applicable to each product category rather than applying a uniform factory-wide calculation. This requirement is linked to how upstream contributions carry into covered outputs under CBAM rules.
Electricity procurement differs from precursor emissions under CBAM
The source describes electricity as remaining relevant for industrial efficiency and broader carbon reporting while requiring separation from precursor-emissions treatment. Under the current CBAM framework described, own indirect electricity emissions are excluded for most covered iron and steel products.
The source also notes specific exceptions, including certain agglomerated ores, where indirect emissions carried through the relevant production chain can apply. As a result, it says investments in renewable electricity may not deliver the same reduction in CBAM embedded emissions as they do under other accounting frameworks.
Rooftop solar generation and renewable power procurement are still described as potentially reducing electricity costs and supporting corporate Scope 2 reporting as well as customer product carbon footprint requirements. For steel processors, each electricity investment is described as needing assessment against the methodology relevant to the intended result rather than assuming all renewable purchases reduce CBAM exposure.
MRV systems must preserve material genealogy from receipt to output
A reliable monitoring, reporting and verification system for steel processing is described as requiring detailed records connecting purchased materials to manufacturing output. Each relevant material receipt should be associated with supplier details including producing installation, steel grade, batch identification, quantity and an emissions record.
The source says warehouse systems need to preserve this identity as materials move into storage and production. Where batches are combined, manufacturers should establish a documented allocation method supported by inventory records.
Production orders then need to connect quantities of precursor materials consumed with corresponding finished output. The source describes this structure as allowing carbon calculations to follow the same material genealogy used for industrial quality control and technical traceability.
For demonstrating different carbon intensities across product families, consistent batch identification and material allocation are described as essential. The same record structure supports allocation decisions tied to verified carbon characteristics rather than only operational energy use.
Procurement decisions rely on verified data alongside price
The availability and quality of precursor-emissions information is presented as influencing procurement decisions for steel inputs. The source says a slightly more expensive material accompanied by reliable verified emissions data may provide a stronger overall commercial proposition than a lower-priced input whose carbon characteristics cannot be substantiated.
Procurement assessments are described as combining material price with technical quality, delivery performance, embedded emissions and data reliability. Manufacturers with sufficient purchasing leverage may formalise these criteria through a supplier scorecard.
The source also states that supply contracts can require regular updates to emissions data while establishing arrangements for confidential disclosure to accredited verifiers. It adds that these provisions allow producers to supply evidence without requiring unrestricted publication of commercially sensitive process information.
Separate assessments required for different production routes and recycled claims
The source describes separate evaluation of precursor emissions by producing installation and product category when integrated steelmakers or processors use multiple production routes. It states that an electric arc furnace input can have a different emissions profile from material produced through a blast furnace route.
The commercial advantage of any route is described as depending on verified emissions information, relevant product specifications and yield achieved during subsequent processing. Procurement departments are said to avoid relying exclusively on generic descriptions such as “green steel” because assessments need actual emissions characteristics carried into finished goods under applicable calculation methodology.
The source further distinguishes claims about recycled content from verified embedded emissions in CBAM contexts. It says scrap proportions can reduce emissions under many manufacturing routes depending on producing installation details and calculation methodology.
A recycled-content statement is described as not automatically establishing an emissions value recognised under CBAM. Manufacturers are said to maintain separate evidence for material composition and regulatory emissions calculations unless underlying verified data support a direct connection between them.
Customer allocation depends on segregation or documented batch genealogy
The source describes differences in precursor emissions as influencing how processors allocate finished products across customer portfolios. It states that manufacturers with access to several verified material sources may direct products made from lowest-emission precursor pools toward customers prepared to recognise associated carbon performance.
Other streams may continue serving markets where purchasing decisions rely primarily on conventional product prices. Such differentiation requires reliable physical segregation or documented material genealogy showing which precursor batches contributed to each finished product.
Without these controls, manufacturers may be unable to substantiate separate carbon claims during independent verification. The source also notes that EU customers may consider changes in emissions performance over time when exporters demonstrate declining precursor intensity alongside improved material yield supported by consistent data.
It adds that where these changes coincide with efficient manufacturing and credible renewable electricity procurement for broader product claims, documentation can support different customer reporting requirements. For processors managing multiple routes and customer segments, it says the same records can support supplier comparisons, production planning and allocation of finished goods according to verified carbon characteristics.
