CBAM implications during the final phase and how the cost of CBAM allowances is calculated

The prices of CBAM allowances for the first quarter of 2026 will be published on April 7, 2026. This marks a significant milestone in the final phase of the CBAM’s implementation. However, to determine the costs of CBAM allowances in 2026, it is necessary to consider several factors, such as specific embedded emissions, the adjustment of CBAM allowances based on free allocation, reference values, the CBAM factor, and others.

Companies must be prepared with a method for calculating the CBAM cost in order to assess the impact of the CBAM on the cost of imported products and to determine profit margins on the products they sell. Such preparation is essential for proper compliance and for the strategic management of financial resources.

Furthermore, although the price of the certificates will be published on April 7, the actual purchase obligation will take effect on February 1, 2027. This underscores the need for companies to budget for these costs in advance in order to comply with the CBAM mechanism.

Given these implications and the CBAM obligations during the definitive phase, Deloitte is hosting a CBAM-focused training session on May 5 that will cover the following topics in detail:

• Introduction to CBAM rules
• CBAM taxation in 2026 and during the definitive phase
• How to calculate the cost of CBAM certificates
• Case studies
• Q&A
