A Way to Incentivize Companies Globally

The EU has introduced the Carbon Border Adjustment Mechanism (CBAM) which is a carbon tariff on the production of carbon-intensive goods imported to the EU such as iron, electricity, hydrogen, cement, fertilizers, and aluminum. This tariff is a way to ensure that a price has been paid for the carbon emissions generated during the production of imported goods.

CBAM Timeline

January 1, 2026
The definitive phase of CBAM begins. Importers must purchase and surrender CBAM certificates corresponding to embedded emissions. Free allowances for domestic producers under the EU ETS begin to phase out.
Early 2026
A legislative proposal from the Commission is expected, following a full review of CBAM later in 2025, to assess its potential extension to other ETS sectors, downstream goods, and indirect emissions, and how to help exporters.
February 1, 2027
Importers will be able to purchase CBAM certificates to cover emissions embedded in goods imported during 2026.
September 30, 2027
The first annual report for the definitive phase is due.
2027-2028 (potential)
Sectors like chemicals and polymers are being considered for inclusion in CBAM scope.
2029
The Commission aims to cut administrative burdens by 25% overall, with SMEs benefiting from a 35% reduction.
2030
Free ETS allowances for domestic producers will decrease to 50% of emissions against ETS benchmarks. The estimated revenue from CBAM is approximately EUR 2.1 billion.

Current phase: Definitive Phase

This marks the end of the 2023–2025 transitional reporting period, shifting to a system where importers must buy CBAM certificates to cover embedded emissions, matching the carbon price paid by EU producers.

Key Aspects of the Current Definitive Phase (From 2026):
  • Financial Obligations: Importers must pay for emissions, with the first declaration and surrender of certificates due by September 30, 2027, for 2026 emissions.
  • Authorized Status: Importers must be registered as “authorized CBAM declarants” to import goods.
  • Scope & Compliance: The scope remains focused on energy-intensive sectors (iron, steel, cement, fertilizers, aluminum, electricity, hydrogen), with stricter rules on calculating emissions and verifying data.
  • Phase-in: This phase aligns with the gradual phasing out of free allowances under the EU Emissions Trading System (ETS).

What is CBAM?

The EU has introduced the Carbon Border Adjustment Mechanism (CBAM) which is a carbon tariff on the production of carbon-intensive goods imported to the EU such as iron, electricity, and hydrogen.

This tariff is a way to ensure that a price has been paid for the carbon emissions generated during the production of imported goods. This means that producers outside the EU will need to account for the carbon emissions associated with their products and importers have to pay a price for them if producers do not pay for the emissions locally.

The mechanism works out a calculation that provides an equivalent carbon price of imported goods to that of the carbon price applied domestically within the EU.

Why was the CBAM introduced?

As companies move their carbon-intensive productions outside the EU and EFTA to countries with less strict climate policies, the risk of ‘carbon leakage’ becomes higher as these products are then imported into EU.

Since the ETS is a regional scheme that does not cover global markets, CBAM was put into place to address this carbon leakage that undermines EU’s net zero ambitions.

The CBAM is EU’s tool to address carbon leakage and eventually replace the allocation of free allowances which is already set to phase out completely by 2034.

How Does the CBAM Work?

Transitional vs. Definitive Phase (October 2023 – 2026)

There will be a gradual phasing in of the CBAM to allow EU and non-EU businesses adjust their policies and work out an effective transition to their compliance.

The Transitional Phase:

Spanning from October 2023 until 2026, this phase will apply to certain imports at high risk of carbon leakage such as cement, iron and steel, aluminium, fertilisers, electricity and hydrogen. As a pilot for CBAM, this phase will also work as a learning stage for all involved parties (importers, producers and authorities) to collect useful information and refine the mechanism for the second phase.

The single requirement of this phase is for importers to produce quarterly reports on the amount of goods and their direct and indirect greenhouse gases (GHG) emissions embedded during the production of these goods. Check Q4 for ways to report.

The Definitive Phase:

The CBAM will be put fully into force starting from 2026. Importers will be able to buy and surrender CBAM certificates and declare emissions.

The products’ scope will be adjusted to include (e.g. cement and fertilizers) more than 50% of the emissions in ETS covered sectors.

What are the three ways to report the amount of goods and their direct and indirect greenhouse gases (GHG) emissions?
  1. Full reporting according to the new methodology (EU method).
  2. Reporting based on an equivalent method (three options).
  3. Reporting based on default reference values published by the EU Commission (only until July 2024, then applied during the transitional period, but up to 20% of the total embedded emissions).

However, starting from January 2025, only the EU method will be accepted.

The reporting mechanism is facilitated through the CBAM Transitional Registry developed by the EU Commission to mainstream the process of communication and submission. Access to the registry is requested through the National Competent Authority (NCA) of the Member State in which the importer is established.

What are the responsibilities of importers?

With the CBAM in full force, importers will need to:

  • Get registered: Before importing goods covered by CBAM, importers need to register with the appropriate national authority.
  • Report emissions annually: Each year, importers will need to declare the quantity of CBAM goods imported and the estimated carbon emissions associated with them.
  • Obtain CBAM certificates: To offset the emissions from imports, importers need to purchase and surrender the corresponding number of CBAM certificates.
  • Keep records for compliance: importers are required to maintain documentation related to CBAM compliance.
What are the benefits of CBAM?

Encouraging Cleaner Production Globally: CBAM creates a market advantage for cleaner production. By making high-emission goods more expensive, it incentivizes companies around the world to invest in cleaner technologies and practices to remain competitive as potential exporters to the EU.

Leveling the Playing Field for EU Industries: because EU companies under the ETS face costs for carbon emissions, they are less competitive against firms in countries without similar schemes. CBAM addresses this by adding a charge on carbon emissions in imported goods, ensuring fair competition and preventing EU companies from being undercut by cheaper imports.

What are the challenges of CBAM?

CBAM introduces a layer of administrative complexity for producers and importers.  This includes registering with authorities, accurately calculating and reporting the embedded emissions of imported goods, requiring verification from suppliers or specialized expertise.  Additionally, importers need to manage CBAM certificates, which involves purchasing and surrendering them to offset their import emissions.

These new procedures can lead to delays at customs if importers are not fully prepared or encounter issues with their documentation.  Adapting internal systems to handle CBAM compliance, such as training staff and investing in new software, can be a challenge, particularly for smaller companies.
