The Carbon Border Adjustment Mechanism (CBAM) is established by Regulation (EU) 2023/956 as a compliance instrument requiring importers to declare the embedded carbon emissions in goods imported into the European Union. Embedded carbon emissions are defined as the total direct and indirect greenhouse gas emissions released during the production of goods, expressed in tonnes of CO2 equivalent per tonne of product. This declaration enables the EU to impose a carbon price on imports equivalent to that paid by EU producers under the EU Emissions Trading System (EU ETS), thereby preventing carbon leakage and promoting climate neutrality.

How to Calculate Embedded Carbon for CBAM

The obligation to calculate and declare embedded carbon applies to importers of goods covered by CBAM, including iron and steel, cement, fertilisers, aluminium, and electricity, as specified in Annex I of Regulation (EU) 2023/956. Importers must quantify embedded emissions using either the default values published by the European Commission or the actual emissions verified by an accredited verifier. This guide explains the methodologies, monitoring plan requirements, verification procedures, and deadlines to ensure full compliance.

Understanding Embedded Carbon Emissions: Direct and Indirect Components

Embedded carbon emissions consist of two main components:

  • Direct emissions: Emissions directly released from production processes, such as combustion of fossil fuels in furnaces or process emissions from chemical reactions (e.g., clinker production in cement manufacturing).
  • Indirect emissions: Emissions associated with electricity consumption during production, calculated by multiplying electricity usage by the grid emission factor of the country where production occurs.

Both components must be included in the embedded carbon calculation to comply with CBAM reporting requirements.

Two Methods to Calculate Embedded Carbon Emissions

Importers can choose between two calculation methods under CBAM:

  1. Default Values Method: Uses default embedded emissions values published annually by the European Commission per product category and country of origin. These values reflect average carbon intensity and simplify compliance but often result in higher CBAM costs.
  2. Actual Emissions Method: Requires a detailed monitoring plan, continuous measurement or calculation-based monitoring of emissions at the installation level, and annual verification by an accredited verifier according to Commission Implementing Regulation (EU) 2023/1773.

Default Values: Simplified but Conservative

The European Commission publishes default embedded carbon values annually in accordance with Article 14 of Regulation (EU) 2023/956. These values are product- and country-specific averages based on verified data from EU ETS and other sources. Using default values is straightforward but generally leads to higher CBAM payments because it does not reflect installation-specific efficiencies or cleaner production methods.

Sample Default Embedded Carbon Values (tonnes CO2e per tonne of product) for Steel Imports in 2024
Country of Origin Product Category Default Embedded Carbon Value
China Hot-rolled steel coil 2.1 tCO2e/t
Turkey Hot-rolled steel coil 1.8 tCO2e/t
Russia Hot-rolled steel coil 2.3 tCO2e/t

Actual Emissions Methodology: Detailed Monitoring and Verification

Importers opting to declare actual embedded emissions must implement a monitoring plan approved by the installation operator. The plan must specify:

  • Monitoring methodology for each emission source (direct and indirect)
  • Data sources, including fuel consumption records and electricity invoices
  • Calculation methods for converting activity data into CO2 equivalent emissions

Continuous measurement or calculation-based monitoring is mandatory, with annual verification by an accredited verifier under Regulation (EU) 2018/2067 (EU ETS verification rules). This method often results in lower CBAM costs but requires significant administrative and technical effort.

Monitoring Plan Requirements

The monitoring plan must be comprehensive and include:

  1. Identification of all emission sources relevant to the product
  2. Procedures for data collection and quality assurance
  3. Emission factor selection and calculation formulas
  4. Responsibilities of personnel involved in monitoring

Approval of the monitoring plan by the installation operator is a prerequisite for using actual emissions in CBAM declarations.

Accredited Verifiers and Verification Process

Verification must be conducted by verifiers accredited under the EU ETS framework (Regulation (EU) 2018/2067). The verifier assesses the monitoring plan, data accuracy, and calculation methods to ensure compliance. Verification reports must be submitted annually alongside CBAM declarations.

CBAM Certificate Pricing and Financial Implications

The CBAM certificate price is linked to the weekly average auction price of EU Allowances (EUAs) in the EU ETS market. In 2024, EUA prices have ranged between approximately €50 and €75 per tonne CO2. Importers pay CBAM certificates corresponding to their declared embedded emissions, making accurate calculation critical to avoid overpayment.

Key Deadlines and Penalties

CBAM Compliance Deadlines and Penalties
Requirement Deadline Penalty for Non-Compliance
First CBAM Declaration and Payment 31 May 2024 (for Q1 2024 imports) Fines up to 5% of global annual turnover or €100,000, whichever is higher
Submission of Monitoring Plan (for actual emissions) Before first CBAM declaration Rejection of actual emissions method; default values applied
Annual Verification Report Submission Within 3 months after calendar year-end Suspension of CBAM certificate issuance

Practical Compliance Checklist for Calculating Embedded Carbon

  1. Identify if your imported products fall under CBAM scope (steel, cement, fertilisers, aluminium, electricity).
  2. Decide whether to use default values or actual emissions method.
  3. If using actual emissions, develop and submit a detailed monitoring plan approved by the installation operator.
  4. Collect and document all relevant data on fuel use, electricity consumption, and production processes.
  5. Engage an accredited verifier under Regulation (EU) 2018/2067 for annual verification.
  6. Calculate embedded carbon emissions accurately, including both direct and indirect emissions.
  7. Prepare and submit quarterly CBAM declarations by the 31st of May, August, November, and February following each quarter.
  8. Purchase and surrender CBAM certificates corresponding to declared emissions at prevailing EUA prices.
  9. Maintain records and verification reports for at least 10 years for audit purposes.

Truth Anchor: Under Regulation (EU) 2023/956, failure to submit accurate CBAM declarations or pay corresponding certificates by 31 May 2024 can result in fines up to 5% of global annual turnover or €100,000, whichever is higher, emphasizing the critical importance of precise embedded carbon calculations.

Frequently Asked Questions

What products are subject to CBAM embedded carbon calculation?

CBAM applies to imports of iron and steel, cement, fertilisers, aluminium, and electricity as listed in Annex I of Regulation (EU) 2023/956. These sectors represent high carbon intensity industries targeted to prevent carbon leakage.

Can I use default embedded carbon values for all my imports?

Yes, importers may use default values published by the European Commission for simplicity. However, this often results in higher CBAM costs compared to using actual emissions verified by an accredited verifier.

What are the requirements for the actual emissions monitoring plan?

The monitoring plan must detail methodologies for measuring direct and indirect emissions, data sources, calculation methods, and quality assurance procedures. It must be approved by the installation operator before use.

Who can verify actual embedded emissions?

Verification must be performed annually by an accredited verifier under Regulation (EU) 2018/2067, ensuring compliance with EU ETS verification standards.

What happens if I miss the CBAM declaration deadline?

Missing the quarterly declaration deadline (e.g., 31 May 2024 for Q1) can lead to fines up to 5% of global annual turnover or €100,000, and possible suspension of import authorisations.

How is the CBAM certificate price determined?

The price is linked to the weekly average auction price of EU Allowances (EUAs) in the EU ETS market. In 2024, prices have fluctuated between approximately €50 and €75 per tonne CO2.
