Steel processors in the Western Balkans face a specific distinction when assessing emissions exposure under the EU Carbon Border Adjustment Mechanism (CBAM). For many covered iron and steel products, reported embedded emissions can be driven more by the carbon intensity of purchased precursor materials and input-to-output conversion efficiency than by electricity used in downstream processing. The assessment therefore requires attention to upstream production routes and verified precursor emissions alongside factory energy use.
Manufacturers that invest in rooftop solar installations or renewable electricity procurement may lower operating costs and improve broader product carbon footprints. However, those changes do not necessarily target the largest emissions components recognised under the current CBAM methodology for iron and steel. For rolling, drawing, cutting, machining and steel fabrication activities, the evaluation needs to extend beyond electricity consumption.
Yield and precursor volumes affect embedded emissions per tonne
Production efficiency influences both manufacturing costs and how carbon intensity is allocated to saleable steel products. When a processor consumes 1,000 tonnes of steel precursor material but produces 900 tonnes of saleable output, emissions linked to the input are spread across a smaller quantity of finished goods. Scrap generated during processing may retain commercial value and can sometimes be recycled.
Even where scrap has value, the emissions calculation must account for material quantities entering the relevant production process under the applicable methodology. Yield is described as particularly important for steel service centres and fabrication facilities where cutting, slitting, stamping and machining can generate substantial offcuts. Monitoring electricity consumption per tonne of finished product is not sufficient to capture this relationship.
Manufacturers are expected to measure tonnes of precursor consumed per tonne of saleable output, together with production yield. The same approach includes scrap quantities and associated scrap revenue as part of the information used in calculations. This links embedded emissions reporting to material performance rather than only energy use.
Traceability requirements shape CBAM data quality
The origin of purchased steel is identified as another major component in the emissions calculation. Processors buying coils, billets, slabs and other steel inputs need 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 verified emissions information required under the applicable CBAM methodology.
Traceability can be difficult when materials are purchased through intermediaries that do not maintain or disclose installation-level carbon data. In such cases, a factory may buy steel produced via a relatively efficient route but be unable to demonstrate that advantage without supporting emissions records. The calculation may then rely on less favourable information, affecting potential commercial benefit from sourcing lower-emission materials.
CN codes and process boundaries determine which emissions are included
The CBAM treatment of processed steel depends on how exported goods are classified and on 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, many downstream finishing operations are treated differently from core iron and steel manufacturing processes.
Even where downstream operations contribute relatively limited direct emissions, emissions associated with relevant upstream precursors can remain embedded in the finished covered product. Manufacturers using multiple production routes are therefore expected to identify inputs and emissions components applicable to each product category rather than apply a single factory-wide calculation. This connects regulatory treatment to both product classification and operational boundaries.
Electricity procurement differs under CBAM compared with other accounting
Electricity remains relevant for industrial efficiency and broader carbon reporting, but its treatment must be distinguished from precursor emissions within CBAM. Under the current CBAM framework for most covered iron and steel products, own indirect electricity emissions are excluded. Specific exceptions can involve indirect emissions carried through relevant production chains, including certain agglomerated ores.
As a result, investments in renewable electricity may not produce the same reduction in CBAM embedded emissions as it does under other accounting frameworks. Rooftop solar generation and renewable power procurement can still reduce electricity costs and support corporate Scope 2 reporting as well as customer product carbon footprint requirements. For steel processors, each electricity investment is assessed against the methodology relevant to the intended result rather than assumed to directly reduce CBAM exposure.
MRV systems must link batches from receipts to finished output
A reliable monitoring, reporting and verification system for steel processing requires detailed records connecting 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 associated emissions record. Warehouse systems need to preserve this identity as materials move into storage and production.
If 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 quantities. This structure is described as enabling 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 elements for demonstrating those differences. The same record discipline supports verification activities tied to product-level claims based on embedded emissions.
Procurement decisions rely on verified precursor data reliability
The availability and quality of precursor emissions information can influence procurement decisions for steel inputs. 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 can combine 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 that incorporates verified information quality. Over time, including verified emissions information in purchasing decisions can direct demand toward steel producers that maintain stronger carbon reporting systems and provide evidence of upstream decarbonisation. Supply contracts can also require regular updates to emissions data.
The contracts described in the source include arrangements for confidential disclosure to accredited verifiers rather than unrestricted publication of commercially sensitive process information. This approach is presented as enabling producers to supply evidence required for verification without broad disclosure of process details.
Different production routes require separate precursor assessments
For integrated steelmakers and processors sourcing material from different production routes, precursor emissions should be evaluated by producing installation and product category. A steel input manufactured using an electric arc furnace (EAF) may have a different emissions profile from material produced through a blast furnace route. The commercial advantage of any route depends on verified emissions information alongside relevant product specifications and yield during subsequent processing.
The assessment approach described avoids relying exclusively on generic descriptions such as “green steel.” Instead it focuses on establishing actual emissions characteristics of purchased material and determining how those emissions carry into finished goods under the applicable calculation methodology. This links route-specific precursor performance to product-level embedded emission outcomes under CBAM rules.
Recycled content claims require separate evidence for CBAM values
Steel processors are also expected to distinguish between claims about recycled material content and verified embedded emissions values recognised under CBAM calculations. A high proportion of scrap can reduce emissions under many manufacturing routes; however, the actual carbon benefit depends on the producing installation and on which calculation methodology applies. A recycled-content statement does not automatically establish an emissions value recognised under CBAM.
Manufacturers should therefore maintain separate evidence for material composition and regulatory emissions calculations unless underlying verified data support a direct connection between them. This distinction is relevant when marketing low-carbon steel products to EU customers whose purchasing requirements may combine recycled-content targets with product-level emissions information supported by verification records.
Verified precursor performance can support customer allocation
Differences in precursor emissions can influence how steel processors allocate finished products across customer portfolios. Manufacturers with access to multiple verified material sources may direct products manufactured from their lowest-emission precursor pool toward customers prepared to recognise associated carbon performance. Other streams may continue serving markets where purchasing decisions rely primarily on conventional product prices.
This differentiation requires reliable physical segregation or documented material genealogy showing which precursor batches contributed to each finished product delivered for specific customer segments. Without such controls, manufacturers may be unable to substantiate separate carbon claims during independent verification activities carried out under relevant processes.
The source also notes that EU customers may consider changes in emissions performance over time when reviewing supplier performance records. Exporters able to demonstrate declining precursor intensity along with improved material yield and consistent supporting data can provide evidence of production-level improvements over time.
When those improvements coincide with efficient manufacturing operations and credible renewable electricity procurement used for broader product claims, documentation can support different customer reporting requirements tied to those claims’ underlying assumptions. For investment assessment across multiple production routes and customer segments, prioritisation is described as covering precursor emissions alongside material yield, fuel consumption and direct process emissions while evaluating electricity measures according to their treatment under the applicable methodology.
