The EU Carbon Border Adjustment Mechanism (CBAM) applies to selected cement and clinker imports from January 1, 2026, introducing a carbon-cost requirement for covered goods. The financial impact depends on embedded emissions and on the CBAM calculation approach used by importers. Delivered import costs also vary with transport routes, port infrastructure, product specifications and local construction demand.
For the third quarter of 2026, the European Commission published a CBAM certificate price of €82.32 per tonne of CO2 equivalent (tCO2e). The published price is an input to prospective liabilities but does not function as a uniform surcharge per tonne of cement. Importer calculations also rely on customs classification, verified or default embedded emissions, a free-allocation adjustment, and deductions for carbon prices paid abroad.
CBAM calculation inputs and ETS market stability reserve changes
CBAM liabilities are influenced by whether embedded emissions are verified or determined using default values under the CBAM framework. Customs classification determines which product category applies for the covered goods. The free-allocation adjustment and eligible deductions for carbon prices paid outside the EU further affect the final CBAM outcome.
A separate EU ETS policy development could affect longer-term carbon-market conditions. On October 20, 2026, the Council and European Parliament reached a provisional agreement to raise the market stability reserve invalidation threshold from 400 million to 700 million allowances. The change remains subject to formal adoption and does not immediately reduce cement producers’ allowance obligations or CBAM certificate costs.
Clinker production emissions and available decarbonisation options
Clinker manufacturing generates emissions from both fuel combustion and chemical transformation of raw materials. Limestone and other materials are heated at high temperatures, releasing CO2 during calcination. Switching to lower-carbon electricity or kiln fuels can reduce energy-related emissions, while process emissions from limestone decomposition remain.
Producers can reduce cement emissions intensity by lowering clinker content in finished products, improving kiln efficiency, changing fuel mixes, and deploying carbon capture where commercially viable. These options involve different technical and financial requirements, particularly when projects require substantial capital investment. Carbon capture can require financing, permits, and dedicated CO2 transport or storage infrastructure.
Alternative fuels depend on procurement arrangements and emissions controls. Lower-clinker formulations may require changes to product certification and customer acceptance. How plants respond to carbon pricing will be shaped by implementation costs, availability of supplementary materials, energy costs, and the ability to sell lower-emission products at commercially viable volumes.
How clinker and finished cement compete across supply chains
Commercial exposure differs between imported clinker and imported finished cement. Imported clinker can be ground and blended at EU facilities, while bagged or bulk cement generally competes closer to final construction markets. Freight costs can be substantial relative to product value.
Sourcing decisions depend on shipping distances, port access, terminal capacity and local construction demand. Mediterranean supply routes can therefore present different competitive conditions compared with inland Central European markets where road and rail economics apply additional constraints. A port-side grinding facility may import clinker from outside the EU, employ local workers, and supply nearby construction customers.
Even when grinding occurs at a port-side site within the EU, CBAM treatment starts with customs classification and embedded emissions of the imported clinker product. The location of final grinding does not remove the need to account for the covered imported material. When supplementary materials are used to reduce clinker content in finished cement, reductions must be evaluated using an appropriate product-specific methodology with independent verification rather than inferred from final product descriptions alone.
Default embedded emissions values and record requirements
The European Commission set definitive-period CBAM default values under Implementing Regulation (EU) 2025/2621, later corrected by Regulation (EU) 2026/1740. For most relevant cement products, applicable default values include a 10% markup in 2026, with higher markups scheduled in subsequent years. Importers can use verified actual emissions when applicable requirements are met.
The default-value framework creates incentives for exporters to establish reliable emissions-monitoring systems. Records referenced in this context include kiln fuel consumption, process emissions, production volumes and movements of clinker through manufacturing and export chains. The quality and granularity of these records can affect how importers calculate liabilities and negotiate purchasing contracts.
Suppliers relying only on default assumptions may face different cost estimates than exporters that substantiate actual emissions under prescribed verification requirements. This difference can influence contract terms tied to CBAM-related cost components for covered goods.
ETS reserve agreement effects on compliance planning
The provisional ETS market stability reserve agreement could preserve a larger stock of allowances for potential future use under applicable rules. It does not require an immediate release of permits or establish a reduction in current carbon prices. For cement manufacturers, exposure continues to depend on allowance prices, phase-out of free allocation, and relative costs of technologies that can reduce process emissions.
The reserve agreement is therefore distinct from measures that directly change plant-level compliance obligations. Investment assessments also need to separate operational improvements from capital-intensive projects. Reducing clinker content may require product certification and customer acceptance; alternative fuels require dependable supply arrangements and emissions controls; carbon capture depends on long-term contracts for CO2 transport and storage alongside an outlook for future carbon prices.
Lenders evaluating projects are expected to consider plant-specific costs and revenues rather than assume that the reserve agreement provides general relief from carbon expenditure. Execution risk, financing risk and debt-servicing risk vary across investment pathways described for decarbonisation measures.
CBAM exposure for exporters in Montenegro, Serbia, Albania and North Macedonia
For producers in Montenegro, Serbia, Albania and North Macedonia, CBAM implications depend on individual plant locations, access to maritime or land transport, exposure to EU customers and verified emissions performance. Exporters with reliable kiln data may be positioned differently in negotiations with European buyers compared with suppliers relying solely on default values.
Changes in national composition of cement imports cannot automatically be attributed to CBAM alone. Trade developments also reflect construction demand levels, selling prices, freight costs and stockpiling ahead of the definitive phase. Product composition matters as well because clinker and finished cement are separate customs goods with different shipping patterns.
Comparing changes in clinker import volumes with changes in customs value of finished cement can produce misleading conclusions about competitiveness due to potentially different emissions intensities across customs categories. Trade analysis also needs to determine where grinding takes place within supply chains and whether intermediate materials are imported before finished goods are produced inside the EU.
Cement certification requirements linked to low-clinker products
Cement used in construction must meet technical specifications covering strength, durability and setting behaviour. Lower-clinker formulations may therefore require changes in certification processes, customer acceptance procedures or applicable local standards where they are sold.
For lenders assessing decarbonisation claims tied to reduced emissions calculations, evidence supporting reduced-emissions performance must be paired with a credible sales forecast for the proposed product. If customers do not purchase sufficient volumes of lower-carbon cement, financial benefits tied to reduced calculated emissions may be offset by underused grinding capacity or carbon-capture capacity.
CBAM accounting alone cannot guarantee demand for higher-cost decarbonisation investments because commercial viability depends on delivered costs, technical requirements and securing customers for resulting output volumes. For European producers specifically, investment decisions continue to rely on how carbon performance aligns with market pricing under delivered-price comparisons by buyers.
