Metal fabricators in the Western Balkans may still report substantial embedded emissions for products exported to the European Union, even after installing solar power, procuring renewable electricity and electrifying manufacturing equipment. The reported outcome can reflect differences between factory energy use and emissions already linked to purchased steel and aluminium precursors.
Companies performing cutting, bending, welding, drilling, coating, machining and assembly may find that the carbon intensity of incoming metal affects their CBAM result more than the electricity consumed during fabrication. This effect is most relevant where manufacturers process purchased metal without operating their own melting or smelting facilities.
Under current CBAM sector methodologies, some downstream finishing activities can fall outside the applicable production boundary. In those cases, emissions associated with relevant precursor materials remain incorporated into the finished product.
Upstream precursor emissions drive product-level CBAM calculations
For metal fabricators preparing product-level carbon calculations, the emissions characteristics of purchased raw materials are a central input. A manufacturer sourcing steel or aluminium needs to identify the original producing installation, the applicable reporting period, whether actual emissions data is available and whether it is verified.
These requirements can be harder to meet when materials are bought through trading companies rather than directly from producers. Distributors may provide material specifications, dimensions and commercial origin without supplying installation-level emissions evidence needed for the applicable CBAM calculation.
Procurement agreements therefore need to preserve the link between delivered metal and the facility where it was produced. Without that connection, a manufacturer may keep accurate electricity records for its own equipment while lacking reliable data for the emissions component that has the greatest effect on the finished product.
Material yield and scrap losses affect embedded emissions intensity
The efficiency with which purchased metal becomes saleable products influences how much precursor material is required for manufacturing. Cutting patterns, nesting efficiency, machining losses and rejection rates determine how much steel or aluminium is consumed relative to finished goods output.
Improving production layouts or reducing rejected components can lower raw-material expenditure while also reducing precursor emissions attributed to each tonne of saleable output. Depending on the applicable production boundary, such improvements may reduce CBAM embedded emissions intensity more than additional renewable electricity purchases.
Scrap recovery can generate offcuts and recoverable material that are sold into recycling markets. While scrap revenue may partially offset material expenditure, it does not necessarily remove the carbon-accounting consequences of purchasing more precursor material than ends up in saleable products.
Renewable electricity benefits depend on how electricity is accounted
Renewable energy investments remain relevant to industrial decarbonisation even when their direct effect on CBAM reporting is limited. Rooftop photovoltaic systems, renewable electricity supply agreements and electrified cutting or welding equipment can reduce energy expenditure and contribute to improvements in corporate emissions performance.
Renewable electricity can also support market-based Scope 2 reporting and product carbon footprints requested by original equipment manufacturers (OEMs) or other industrial customers. However, workshop electricity treatment under a customer product-footprint methodology may differ from its treatment within the applicable CBAM production boundary.
A sales department should therefore avoid presenting renewable electricity procurement as automatic evidence of reduced CBAM embedded emissions. The same investment may still be commercially valuable for electricity-cost reductions, corporate decarbonisation commitments and customer sustainability requirements without producing an equivalent regulatory benefit under CBAM.
Equipment upgrades require separate assessments under different reporting boundaries
Metal fabricators considering new production equipment should separate direct operational savings from emissions reductions recognised under specific accounting frameworks. An investment in a more efficient laser-cutting system or welding line can be assessed initially through electricity consumption, productivity improvements and manufacturing performance.
The manufacturer can then evaluate how that investment affects product emissions under the methodology requested by customers. Where the current CBAM production boundary excludes electricity tied to relevant fabrication activity, a financial assessment should not include a regulatory carbon benefit that the methodology does not recognise.
This distinction also matters for regional industrial policy and financing. Green loans and grant programmes supporting renewable electricity may improve factory energy performance but may not independently deliver substantial improvements in the CBAM position of downstream metal processors.
Customer requests can require different carbon figures for the same product
EU industrial customers may request more than one emissions figure for the same fabricated product. A procurement or sustainability department may require a product carbon footprint incorporating workshop electricity consumption, while a customer’s customs function may use a separate CBAM embedded-emissions calculation.
Both figures can be appropriate within their respective methodologies even when reported emissions intensities differ. Exporters are expected to provide clearly labelled calculations rather than use one figure for every reporting purpose.
A short reconciliation explaining different production boundaries, energy treatment and precursor contributions can help customers understand why values are not identical. Supporting evidence should remain consistent across both calculations while each reporting system applies its own methodology to relevant factory records.
Material genealogy supports traceable differentiation across CN codes
A factory’s carbon-data system should follow the physical movement of steel and aluminium through manufacturing. Material batches need recording when received, connection to production orders and adjustment for scrap generation before linking to finished products.
Electricity and fuel consumption records can be allocated to relevant processes where needed for broader product-footprint calculations. This shared evidence base allows manufacturers to produce different emissions outputs without changing underlying historical production information.
The approach becomes especially important when exports include several finished products classified under different Combined Nomenclature (CN) codes but manufactured using the same precursor materials. Allocation rules must be established before commercial results are known, including avoiding assignment of lowest-emission precursor or renewable electricity benefits solely to highest-margin customers unless supported by physical records and applicable calculation methodology.
Differentiated inputs and customer design changes can reduce material-related emissions
Manufacturers sourcing metal from several producers may distinguish finished products based on verified carbon intensity of precursor inputs. Where lower-emission steel or aluminium is physically segregated and traced through production, a differentiated product line can be supported by stronger emissions evidence.
This requires production and warehouse controls demonstrating which materials were consumed in relevant manufacturing orders. Differentiation cannot be achieved simply by reallocating favourable emissions values after production has been completed.
Certain material efficiency improvements depend on decisions made by industrial customers rather than fabricators alone. Product dimensions, component specifications and manufacturing requirements influence cutting patterns and scrap quantities during production.
If customer designs contribute to poor material yield, manufacturers can use verified precursor emissions information and production records to demonstrate potential benefits from modifying those specifications. A relatively small dimensional adjustment or improved nesting arrangements can reduce both purchased material quantities and embedded emissions associated with finished products.
This creates an opportunity for exporters and customers to negotiate shared economic benefit based on measurable reductions in material consumption connected to identifiable changes in manufacturing cost and product carbon intensity.
