Steel companies supplying the European Union are facing increased compliance attention on material utilisation when determining embedded emissions under the Carbon Border Adjustment Mechanism (CBAM). European Commission guidance states that, for steel products produced from CBAM precursors, the emissions calculation uses the precursor mass before cutting. This approach applies instead of relying only on the mass retained in the finished product.
Cutting is described as outside the relevant CBAM system boundary for iron and steel transformation. However, discarded material cannot be omitted from the precursor-based emissions allocation. The full mass entering the production process remains the basis for distributing embedded emissions, so lower conversion yields can raise emissions per tonne of saleable output without adding counted emissions from cutting itself.
Precursor allocation and losses in finished steel output
The implications extend to steel fabricators outside the EU under the same precursor allocation logic. A facility using 1.10 tonnes of steel precursor to produce one tonne of finished product cannot exclude emissions linked to the remaining 0.10 tonnes trimmed away from its CBAM calculation. The embedded emissions associated with the full quantity of precursor entering production must still be accounted for under the applicable methodology.
As a result, material utilisation affects not only metal costs but also the embedded emissions assigned to each tonne of finished output. Evidence requirements therefore focus on both input and output quantities tied to CBAM-covered calculations. For processors in Serbia, Turkey and other Southeast European markets, this includes how losses occur during production.
Operational evidence needed for CBAM preparation
For Serbian, Turkish and other Southeast European processors, cutting plans and nesting efficiency are identified as relevant to CBAM preparation. Scrap recovery and enterprise resource planning (ERP) records are also cited as part of the evidence base. Documentation must support both the quantity of precursor entering production and the quantity of CBAM-covered output generated from it.
The operational data needed for compliance extends beyond furnace-related emissions to include material flow across manufacturing steps. This includes precursor quantities, cutting losses, output volumes, and scrap recovery figures connected through production records. The aim is to ensure that calculations can be supported throughout the manufacturing process using consistent inputs and outputs.
Certificate reference price links conversion yield to cost
The cost implications are tied to changes in Europe’s steel market linked to trade restrictions, investment activity 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 linked this recovery to a tighter EU trade framework that limits tariff-free imports and applies a 50% tariff to imports exceeding quota levels. The carbon-cost implications of precursor allocation can be illustrated using the Q3 2026 CBAM certificate reference price of EUR 82.32 per tonne of CO₂ equivalent. At that reference price, differences in allocated emissions for finished products can translate into measurable landed-cost differences across high-volume supply contracts.
The final payable amount depends on the applicable free-allocation adjustment 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 emissions allocation under CBAM rules.
Procurement focus on yield alongside embedded emissions
For EU buyers comparing otherwise similar suppliers, conversion yield can become an additional procurement consideration. Better material utilisation can reduce metal costs while also lowering the quantity of precursor emissions allocated per tonne of saleable finished product. This links operational performance with embedded-emissions outcomes relevant for CBAM calculations.
The evidence requirements cover precursor quantities, cutting losses, output volumes, scrap recovery and records connecting those figures to production results. For steel suppliers seeking to demonstrate their emissions performance under CBAM, reliable production data must support calculations across manufacturing steps rather than only at specific points in production.
As CBAM-related costs become part of import economics, material yield and carbon intensity are increasingly connected variables for competitiveness among steel processors supplying EU demand. In practice, this connection depends on how precursor inputs translate into saleable output quantities under the CBAM methodology.
