Steel processors supplying the European Union are facing increased attention on material utilisation when calculating embedded emissions under the Carbon Border Adjustment Mechanism (CBAM). European Commission guidance states that, for steel products made from CBAM-covered precursors, emissions are calculated using the precursor mass before cutting. The approach applies instead of using only the mass retained in the finished product.
Cutting is outside the relevant CBAM system boundary for iron and steel transformation. However, discarded material cannot be excluded from the precursor-based emissions calculation. The full mass entering the production process remains the basis for allocating embedded emissions, so lower conversion yields can raise emissions per tonne of saleable output without adding counted emissions from cutting.
Material losses and emissions per tonne of finished steel
The allocation rules affect facilities beyond EU borders. A producer using 1.10 tonnes of steel precursor to produce one tonne of finished product cannot remove the emissions tied to the remaining 0.10 tonnes trimmed away from its CBAM calculation. Under the applicable methodology, emissions embodied in the full quantity of precursor entering production must be accounted for.
As a result, material utilisation becomes relevant not only to metal costs but also to embedded emissions attributed to each tonne of finished output. The relationship between precursor input and saleable output therefore influences how embedded emissions are distributed across deliveries. This links production yield with CBAM reporting requirements for steel processors.
Evidence needed from Southeast European steel fabricators
For Serbian, Turkish and other Southeast European processors, operational records tied to cutting and material handling are part of CBAM preparation. Cutting plans, nesting efficiency, scrap recovery and enterprise resource planning (ERP) records are identified as relevant evidence. Documentation needs to support both the quantity of precursor entering production and the quantity of CBAM-covered output generated from it.
The evidence requirement focuses on material flow through manufacturing rather than only final product mass. Processors preparing for CBAM calculations therefore need traceability between input precursor quantities and output volumes used for reporting. The records are intended to establish what portion of precursor-related embedded emissions corresponds to produced steel.
EU market developments and CBAM certificate reference pricing
The compliance implications are occurring alongside changes in Europe’s steel market linked to trade restrictions, investment and carbon costs. On 13 October 2026, EUROFER reported that approximately 10 million tonnes of European crude steelmaking capacity resumed production during 2026. The industry group also reported at least EUR 3.4 billion in investment decisions, with a further EUR 2.4 billion expected by the end of the year.
EUROFER connected the recovery to a tighter trade framework that limits tariff-free imports and applies a 50% tariff to imports exceeding quota levels. For cost illustration, the Q3 2026 CBAM certificate reference price was cited as EUR 82.32 per tonne of CO₂ equivalent. At that level, differences in emissions allocated to finished products can translate into measurable landed-cost differences across high-volume supply contracts.
The final payable amount depends on factors including applicable free-allocation adjustments and any eligible carbon price effectively paid in the country of origin. Even so, underlying production and material-flow data determine the starting point for embedded emissions allocation under CBAM rules.
Procurement focus on yield-linked embedded emissions
For EU buyers comparing suppliers with otherwise similar offerings, conversion yield can become an additional procurement consideration under CBAM-linked cost structures. Better material utilisation can reduce metal costs while also lowering the quantity of precursor emissions allocated per tonne of saleable finished product. This affects how embedded emissions translate into import-related compliance economics.
The operational evidence extends beyond furnace-related figures to include precursor quantities, cutting losses, output volumes and scrap recovery records linked through enterprise systems. For steel suppliers seeking to demonstrate their emissions performance under CBAM, reliable production data must support calculations across manufacturing steps leading from precursor input to covered output.
As CBAM-related costs become part of import economics, material yield and carbon intensity are increasingly connected variables for competitiveness among steel processors supplying the EU market.
