CBAM aims to balance the carbon cost difference between EU production and imported goods while preventing carbon leakage. By adjusting free allocations, it ensures fair competition and makes carbon reporting and management
The European Union’s Carbon Border Adjustment Mechanism (CBAM) is an important regulatory tool designed to help achieve global climate targets and prevent carbon leakage—a risk that arises when carbon-intensive production shifts outside the EU to avoid carbon pricing. The mechanism aims to eliminate the gap in carbon costs between EU producers and non-EU producers exporting similar carbon-intensive products into the EU market. In doing so, CBAM creates a level playing field, strengthens fair competition, and supports the EU’s long-term climate objectives.
CBAM is built on the principle of an inseparable carbon cost. When carbon-intensive sectors operating within the EU compete through foreign trade with imported products manufactured under lower or non-equivalent carbon costs, emissions may effectively relocate rather than decrease. This undermines the EU’s emission reduction efforts. To address this imbalance, CBAM requires importers to report the embedded carbon emissions within imported products and purchase a corresponding number of CBAM certificates, aligning the carbon cost of imports with the carbon pricing level applied inside the EU Single Market.
Under the existing EU Emissions Trading System (EU ETS), certain sectors have been granted free allowances to support production activities. These allowances were introduced to prevent companies from facing sudden financial burdens while adapting to carbon pricing obligations and to reduce the risk of carbon leakage during the transition toward full carbon cost internalization.
With CBAM now entering implementation, the issue of adjusting free allowances in the context of imports has gained prominence. The number of CBAM certificates required for imported goods may be reduced in proportion to the level of free allowances still applied to equivalent domestic production under the EU ETS. The fundamental purpose of this approach is to maintain the most balanced and fair carbon cost alignment between imported products and EU-manufactured equivalents, ensuring competitive equity while preserving the integrity of carbon pricing at the EU’s trade borders.
The draft regulation addressing the adjustment of free allowances under CBAM outlines several practical principles that both importers and EU producers must consider:
1. Calculation Basis: Real Verified Data vs Default Estimated Values
If emissions are declared based on actual measured, verified, and documented company data, the free allowance adjustment is also calculated using that real data basis.
If emissions are declared using default or estimated values, the adjustment will also rely on those same default indicators.
This distinction creates a meaningful practical impact, particularly in emission reporting, documentation controls, and future audit readiness.
2. Transition Timeline and Benchmark Updates
The mandatory CBAM application begins in 2026.
Since final EU ETS benchmark indicators for some sectors have not yet been fully published, initial CBAM emission indicators will rely on estimated ETS benchmarks.
Once final benchmark values are officially published, they will be reviewed and updated, and revised values will apply from 2027 onward.
This transition period provides companies inside and outside the EU with time for compliance preparation, but it also represents a critical strategic window for establishing structured carbon data foundations.
3. Sector-Specific Differences in Free Allowance Adjustments
In the first phase, CBAM applies to product groups with high carbon intensity, including:
Cement
Iron and steel
Aluminium
Fertilizers
Hydrogen
Electricity
The adjustment of free allowances may vary depending on product classifications and sectoral data maturity. For example, in the case of electricity imports, no free allowance adjustment is applied (coefficient 0), while different reduction corridors may apply to imports of steel or similar heavy industrial goods.
CBAM compliance is often perceived purely as a regulatory obligation. In reality, it is also a direct cost planning and sustainability management factor for companies engaged in carbon-intensive imports.
Key practical implications include:
Adjusted free allowance calculations can directly influence the total carbon cost embedded in imported product pricing.
Data consistency, traceability, and documentation credibility create more security than collecting high volumes of unverified data.
Methodological inconsistency or undocumented assumptions pose a greater audit risk than transparent data gaps supported by an improvement plan.
CBAM, in parallel with the EU ETS’s gradual reduction of free allowances, encourages companies to build more robust reporting structures and carbon management foundations. This also provides companies with a strategic opportunity to evolve carbon metrics into a management input, rather than a reporting output alone.
CBAM is a critical mechanism designed to support fair and balanced carbon pricing at the EU’s trade borders. The adjustment of free allowances ensures that:
EU producers remain protected from sudden cost shocks,
Importers are not exposed to disproportionate carbon pricing imbalances,
Carbon cost alignment is structured, proportional, and defensible for future reporting cycles,
and that companies operate within a framework that can scale with regulatory evolution.
Preparing for CBAM is not just a legal requirement—it is a strategic step for managing carbon costs effectively and gaining a competitive advantage in an increasingly carbon-regulated global trade environment.
