EU Carbon Border Adjustment Mechanism (CBAM)
The Carbon Border Adjustment Mechanism is an EU policy that puts a carbon price on imports to prevent carbon leakage and ensure fair competition for EU companies subject to carbon pricing.
CBAM levels the playing field by requiring importers to purchase certificates covering the embedded emissions of certain goods, ensuring that imported products face the same carbon costs as EU-produced goods.

Price Carbon in Imports
Embedded emissions - measure carbon in imported goods
CBAM certificates - purchase based on emissions
EU ETS price - linked to carbon market
Prevent Carbon Leakage
Level playing field - same carbon costs for imports
No relocation incentive - remove advantage of moving
Protect EU industry - maintain competitiveness
Drive Global Decarbonization
Export pressure - encourage non-EU decarbonization
Carbon pricing adoption - incentive for similar policies
Supply chain action - reduce embedded emissions
CBAM prevents carbon leakage and drives global climate action
Purpose & Objectives
CBAM is designed to address carbon leakage while supporting the EU's climate goals and encouraging global climate action.
Prevent Carbon Leakage
Carbon leakage occurs when companies relocate production to countries with weaker climate policies to avoid carbon costs. CBAM addresses this by applying the same carbon price to imports, removing the incentive to relocate.
Level Playing Field
EU companies subject to the EU ETS face carbon costs. CBAM ensures that imported goods face equivalent carbon costs, preventing unfair competition from countries with weaker climate policies.
Encourage Global Decarbonization
By putting a price on carbon in imports, CBAM creates an incentive for non-EU countries to adopt their own carbon pricing policies and decarbonize their industries to reduce CBAM costs.
Support EU Climate Goals
CBAM supports the EU's climate targets by ensuring that carbon pricing remains effective without leading to carbon leakage, maintaining the environmental integrity of EU climate policy.
Climate Policy Integrity
CBAM ensures that EU climate policy remains effective by preventing carbon leakage while encouraging global climate action.
How CBAM Works
CBAM operates through a system of reporting, certificate purchase, and surrender based on the embedded emissions of imported goods.
1. Importer Registration
EU importers must register as CBAM declarants in their member state. Only registered declarants can import CBAM-covered goods into the EU.
2. Emissions Reporting
Importers must report the embedded emissions of their imports quarterly. Non-EU exporters must provide emissions data, which can be verified by EU-approved verifiers.
3. Certificate Purchase
In the definitive phase, importers must purchase CBAM certificates from national authorities. Certificate prices are based on the weekly average EU ETS carbon price.
4. Certificate Surrender
Importers must surrender CBAM certificates equivalent to the embedded emissions of their imports by May 31 of the following year. Certificates are surrendered to national authorities.
5. Adjustment for Carbon Pricing
If the exported product has already paid a carbon price in the country of origin, this can be deducted from the CBAM certificate requirement to avoid double pricing.
Certificate-Based System
CBAM uses a certificate system linked to the EU ETS carbon price, ensuring that imports face equivalent carbon costs to EU production.
Sectors Covered
CBAM initially covers carbon-intensive sectors at high risk of carbon leakage, with potential for future expansion.
Iron and Steel
Covers iron, steel, and related products including tubes, pipes, and fittings. These are among the most carbon-intensive industrial sectors.
Aluminum
Covers primary aluminum and aluminum products. Aluminum production is energy-intensive and significant for global trade.
Cement
Covers cement, clinker, and related products. Cement production involves significant process emissions from calcination.
Fertilizers
Covers ammonia, nitric acid, and other fertilizers. Fertilizer production is energy-intensive and involves process emissions.
Electricity
Covers imported electricity. This addresses carbon leakage in power generation and encourages decarbonization of exported electricity.
Hydrogen
Covers hydrogen and its derivatives. Hydrogen is expected to play a key role in the energy transition and its production can be carbon-intensive.
Potential for Expansion
The EU may expand CBAM to additional sectors over time, including chemicals, organic chemicals, polymers, and other carbon-intensive industries.
Implementation Timeline
CBAM is being implemented in phases, starting with a transitional reporting period followed by full implementation.
Transitional Period (October 2023 - December 2025)
Importers must report embedded emissions quarterly but no CBAM certificates are required. This period allows companies to prepare and adapt to the new requirements.
Definitive Phase Start (January 2026)
Importers must begin purchasing CBAM certificates to cover embedded emissions. The system becomes fully operational with financial obligations.
Phased EU ETS Free Allowance Phase-Out (2026-2034)
Free allowances under the EU ETS for covered sectors will be gradually phased out, with CBAM replacing them to maintain competitiveness while ensuring carbon pricing.
Full Implementation (2034 onwards)
By 2034, free allowances for covered sectors will be fully phased out. CBAM will be fully operational as the primary mechanism for addressing carbon leakage.
Gradual Transition
The phased implementation allows companies to adapt gradually, with the transitional period providing time to build capacity and prepare for full compliance.
Reporting Requirements
CBAM requires detailed reporting on embedded emissions to ensure accurate calculation of certificate requirements.
Quarterly Reports
Importers must submit quarterly reports covering the total quantity of imports, embedded emissions, and carbon price already paid in the country of origin.
Emissions Data
Reports must include actual emissions data where available. Default values may be used in the transitional period, but actual data is required in the definitive phase.
Verification
Emissions data from non-EU exporters may be verified by EU-approved verifiers to ensure accuracy and reliability of the reported information.
Record Keeping
Importers must maintain records of their CBAM reports and supporting documentation for at least 5 years for audit and verification purposes.
Data-Driven System
CBAM relies on accurate emissions data to calculate certificate requirements, emphasizing the importance of robust measurement and reporting systems.
CBAM Certificate Calculation
CBAM certificates are calculated based on the embedded emissions of imported goods and the EU ETS carbon price.
Embedded Emissions
The total greenhouse gas emissions embedded in the imported product, including direct emissions from production and indirect emissions from electricity use.
Certificate Price
CBAM certificates are priced based on the weekly average EU ETS carbon price, ensuring that imports face the same carbon costs as EU production.
Calculation Formula
Number of certificates = Embedded emissions (tCO2e) × Quantity imported. Cost = Number of certificates × Certificate price (€/tCO2e).
Adjustment for Carbon Pricing
If a carbon price has already been paid in the country of origin, this amount can be deducted from the CBAM certificate requirement to avoid double pricing.
EU ETS Linkage
The linkage to the EU ETS carbon price ensures that CBAM reflects the cost of carbon in the EU, maintaining policy consistency and effectiveness.
Compliance Obligations
EU importers have specific obligations to comply with CBAM requirements.
Registration
Importers must register as CBAM declarants in their member state before importing covered goods. Registration is required for each member state where imports occur.
Reporting
Importers must submit quarterly reports on embedded emissions. Reports must be submitted by the end of the month following the quarter.
Certificate Purchase
In the definitive phase, importers must purchase CBAM certificates from national authorities to cover the embedded emissions of their imports.
Certificate Surrender
Importers must surrender CBAM certificates by May 31 of the following year to cover the embedded emissions of their imports from the previous year.
Non-Compliance Consequences
Failure to comply with CBAM obligations can result in penalties, including fines and restrictions on importing covered goods into the EU.
Impact on Businesses
CBAM affects businesses in the EU and globally, with implications for costs, supply chains, and competitiveness.
EU Importers
EU importers of covered goods face increased costs due to CBAM certificate requirements. They must invest in reporting systems and supply chain engagement to measure embedded emissions.
Non-EU Exporters
Non-EU exporters to the EU must provide emissions data and may face reduced competitiveness if their products have high embedded emissions. Decarbonization can reduce CBAM costs.
EU Producers
EU producers benefit from a level playing field as imports face equivalent carbon costs. However, they must continue to decarbonize as free allowances are phased out.
Supply Chain Implications
CBAM drives supply chain transparency and decarbonization as companies seek to measure and reduce embedded emissions to lower CBAM costs.
Global Impact
CBAM has global implications, affecting trade flows, supply chains, and climate policy beyond the EU, encouraging worldwide decarbonization.
