The European Commission’s Q3 2026 CBAM certificate reference price is set at EUR 82.32/tCO₂e, affecting how carbon costs are reflected in the landed cost of imported goods. The technical emissions-accounting rules that determine the emissions volumes subject to CBAM can influence the final carbon cost. The guidance points to factors including cutting yields, precursor averaging, clinker ratios, fertiliser blending and electricity matching.
The reference price rose from EUR 75.28/tCO₂e in Q2 2026. While certificates covering 2026 imports will be purchased later, the quarterly reference price applies to the period. It is also described as providing companies with a basis for financial accruals and commercial negotiations.
Calculation rules linked to CBAM certificate pricing
European Commission guidance describes how calculation rules interact with the certificate reference price. In steel, steel fabricators must account for precursor material before cutting. Where the same precursor is sourced from multiple installations, producers generally use a weighted average unless they can demonstrate a segregated supply route.
Cement calculations include emissions associated with clinker precursors. For fertilisers, physically blending liquid fertilisers can prevent individual components from retaining separate carbon identities. Electricity calculations rely on actual emissions values that require a power purchase agreement (PPA) and matched physical nominations.
These requirements can change the quantity of CO₂ equivalent ultimately subject to CBAM cost. The emissions volumes determined through these methods therefore affect the carbon cost applied to imports.
Carbon cost sensitivity at EUR 82.32 per tonne of CO2e
At EUR 82.32/tCO₂e, a difference of 0.5 tonnes of CO₂e per tonne of product corresponds to approximately EUR 41 per tonne. The figure is stated as being before any free-allocation adjustment or any eligible deduction for a carbon price effectively paid abroad.
A difference of 1.0 tonne of CO₂e equates to approximately EUR 82 per tonne on the same basis. The relationship between emissions quantities and the certificate reference price is therefore presented as a key driver of cost variation.
Procurement, financing and contract terms under CBAM
The cost sensitivities are described as influencing sourcing decisions across steel, aluminium, cement and fertilisers. They may also affect the commercial value of renewable electricity PPAs, low-carbon precursor supply agreements and investments in material efficiency.
For banks, CBAM exposure is described as becoming relevant to core credit analysis rather than being limited to environmental, social and governance reporting. Carbon assumptions are said to need inclusion in working-capital forecasts, borrowing-base calculations and downside scenarios because errors in emissions methodology can change landed costs and gross margins.
EU importers can address part of the uncertainty through supplier contracts specifying responsibility for emissions data. The guidance also references contract terms covering consequences if verification fails and allocation of additional costs if actual emissions values cannot be used and default values apply.
Exporters are described as needing to identify technical variables with the greatest potential impact on costs expressed in euros per tonne. They also need supporting data that can be audited.
With the CBAM reference price exceeding EUR 80/tCO₂e, the practical effects are described as extending beyond climate policy into procurement, credit assessment and industrial strategy.
