Steel processors in the Western Balkans face a key distinction when assessing emissions exposure under the EU Carbon Border Adjustment Mechanism (CBAM). For many covered iron and steel products, the carbon intensity of purchased precursor materials and how efficiently those inputs are converted into finished goods can outweigh electricity used during downstream processing.
Companies that invest 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 changes do not necessarily address the largest emissions components recognized under the current CBAM methodology for iron and steel.
For firms involved in rolling, drawing, cutting, machining and steel fabrication, the assessment is described as extending beyond factory energy consumption. It also needs to cover upstream production routes, verified precursor emissions and material yield.
Material yield and scrap handling affect embedded emissions per tonne
Production efficiency is presented as affecting both manufacturing costs and the carbon intensity allocated to saleable steel products. The source material describes an example where 1,000 tonnes of steel precursor material are consumed to produce 900 tonnes of saleable output.
In that scenario, the emissions associated with input materials are distributed across a smaller quantity of finished goods. The calculation is also linked to how much material enters the relevant production process under the prescribed CBAM methodology.
Scrap generated during processing may retain commercial value and can sometimes be recycled. Even so, the emissions calculation must still account for the quantities of material entering the process.
The source highlights that yield is particularly important for steel service centres and fabrication facilities. Cutting, slitting, stamping and machining operations are cited as generating substantial quantities of offcuts.
Measuring electricity consumption per tonne of finished product is described as insufficient to capture this relationship. Manufacturers are said to also measure tonnes of precursor consumed per tonne of saleable output, along with production yield, scrap quantities and associated scrap revenue.
Verified precursor data relies on installation-level traceability
The origin of purchased steel is described as another major element in CBAM-related emissions calculations. Processors buying coils, billets, slabs and other inputs are said to need information beyond material grade and the identity of the trading company.
Where actual emissions values are used, records should identify the original producing installation. Those records should also provide the corresponding verified emissions information required under the applicable CBAM methodology.
The source notes that traceability can be difficult when materials are purchased through intermediaries that do not maintain or disclose installation-level carbon data. It adds that a factory may buy steel made through a relatively efficient route but still be unable to demonstrate that advantage if supporting emissions records are unavailable.
In such cases, calculations may rely on less favourable information. This can reduce any commercial benefit from sourcing lower-emission materials.
CN codes and process boundaries determine which emissions remain embedded
The CBAM treatment of processed steel is described as depending on how exported goods are classified and which production activities are involved. 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. Even where downstream operations contribute relatively limited direct emissions, upstream precursor emissions can remain embedded in the finished covered product.
The source says manufacturers using multiple production routes need to identify inputs and emissions components applicable to each product category. It also states that applying a single uniform factory-wide calculation is not aligned with this requirement.
Electricity procurement affects Scope 2 reporting differently from CBAM
The source material distinguishes electricity’s role in industrial efficiency and broader carbon reporting from its treatment in CBAM embedded emissions. Under the current CBAM framework described for most covered iron and steel products, own indirect electricity emissions are excluded.
It also notes specific exceptions, including certain agglomerated ores, where indirect emissions carried through the relevant production chain can be involved. As a result, 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 capable of reducing electricity costs. They can also support corporate Scope 2 reporting and customer product carbon footprint requirements.
For steel processors, the source says each electricity investment should be assessed against the methodology relevant to the intended result. It cautions against assuming all renewable electricity purchases directly reduce CBAM exposure.
MRV systems must connect batch genealogy from receipts to output
A reliable monitoring, reporting and verification (MRV) system for steel processing is described as requiring detailed records linking purchased materials to manufacturing output. Each relevant material receipt should be associated with supplier details, producing installation information, 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 must then connect quantities of precursor materials consumed with corresponding finished output. The structure is described as allowing carbon calculations to follow the same material genealogy used for industrial quality control and technical traceability.
For companies seeking different carbon intensities across product families, consistent batch identification and material allocation are described as essential requirements.
Supplier decisions depend on verified emissions reliability
The availability and quality of precursor emissions information can influence procurement decisions for steel inputs. The source describes a scenario where a slightly more expensive material with reliable verified emissions data may offer a stronger overall commercial proposition than a lower-priced input with unsubstantiated carbon characteristics.
Procurement assessments are described as combining material price with technical quality, delivery performance, embedded emissions and data reliability. Manufacturers with sufficient purchasing leverage may formalize these criteria through a supplier scorecard.
The source adds that over time including verified emissions information in purchasing decisions can direct demand toward producers with stronger carbon reporting systems. It also states that supply contracts can require regular updates to emissions data.
It further notes arrangements for confidential disclosure to accredited verifiers. These provisions are described as enabling producers to supply evidence without requiring unrestricted publication of commercially sensitive process information.
Different production routes require separate carbon assessments
The source material says precursor emissions should be evaluated by producing installation and product category when integrated steelmakers or processors use multiple production routes. It gives an example contrasting electric arc furnace (EAF)-produced inputs with those produced through blast furnace routes.
A particular route’s commercial advantage is described as depending on verified emissions information, relevant product specifications and yield achieved during subsequent processing. The source says procurement departments should avoid relying exclusively on generic descriptions such as “green steel.”
The assessment needs to establish actual emissions characteristics of purchased materials. It must also determine how those emissions carry into finished goods under the applicable calculation methodology.
Recycled content claims require separate evidence for CBAM values
The source says steel processors should distinguish between recycled material content claims and verified embedded emissions values recognized under CBAM. It notes that a high proportion of scrap can reduce emissions under many manufacturing routes but that actual carbon benefit depends on producing installation details and calculation methodology.
A recycled-content statement is described as not automatically establishing an emissions value recognized under CBAM. The source says manufacturers should maintain separate evidence for material composition and regulatory emissions calculations unless underlying verified data support a direct connection between them.
This distinction is described as relevant when marketing low-carbon steel products to EU customers whose purchasing requirements may combine recycled-content targets with product-level emissions information.
Customer allocation depends on segregated batches or documented genealogy
The source states that differences in precursor emissions can influence how steel processors allocate finished products across customer portfolios. Manufacturers with access to several verified material sources may direct products made from their lowest-emission precursor pool toward customers prepared to recognize associated carbon performance.
Other streams may continue serving markets where purchasing decisions rely primarily on conventional product prices. The source says differentiation requires reliable physical segregation or documented material genealogy showing which precursor batches contributed to each finished product.
Without those controls, manufacturers may be unable to substantiate separate carbon claims during independent verification. It also notes that EU customers may consider development of emissions performance over time through declining precursor intensity and improved material yield supported by consistent data.
The source further states that where such changes align with efficient manufacturing and credible renewable electricity procurement for broader product claims, documentation can support different customer reporting requirements. For processors managing multiple production routes and customer segments, it says consistent records can support supplier comparisons, production planning and allocation of finished goods according to verified carbon characteristics.
