Market Mechanics

How EU CBAM Works

CBAM mirrors EU ETS by requiring importers to purchase certificates corresponding to the carbon price. The CBAM certificate price equals the weekly average EU ETS auction price (or quarterly average in 2026). Embedded emissions include direct emissions plus indirect for cement and fertilisers.

Only "Authorized CBAM Declarants" can import covered goods — importers must hold an EORI number, maintain a clean compliance record, and provide financial guarantees.

Deductions are allowed for carbon prices effectively paid in the country of origin — but only if documented. A 50-tonne de minimis threshold applies to iron & steel, aluminium, fertilisers, and cement (NOT electricity or hydrogen).

The CBAM Factor phases in from 97.5% in 2026 down to 0% by 2034, as free EU ETS allowances phase out. Full CBAM liability begins in 2034, creating a critical multi-year compliance arc for exporters worldwide.

6 Sectors Covered by EU CBAM

CBAM applies to imports of goods in 6 carbon-intensive sectors. Each sector includes both direct and indirect emissions where applicable. The covered sectors represent approximately 80% of EU ETS emissions and are critical to global trade flows.

Cement
Clinker production and grinding. Direct and indirect emissions covered.
Active
Iron & Steel
98% of early declared volumes. Dominant sector under CBAM.
Active
Aluminium
Primary and secondary smelting. Energy-intensive process.
Active
Fertilisers
Direct and indirect emissions covered. Critical agricultural input.
Active
Hydrogen
Green, blue, and grey hydrogen. All types covered.
Active
Electricity
Import-based coverage. Embedded in imported goods.

Key Design Features

CBAM is designed to level the playing field between EU producers facing ETS costs and importers from jurisdictions without equivalent carbon pricing. The mechanism creates real economic exposure for global exporters while allowing for deductions where carbon prices have been paid.

CBAM Factor Phase-In

97.5% in 2026 decreasing to 0% by 2034, as free ETS allowances phase out. Financial exposure grows predictably, forcing exporters to plan long-term cost mitigation.

EU ETS Price Mirroring

CBAM certificate price equals the weekly average EU ETS auction price (quarterly average in 2026). Direct linkage to EU carbon market price signals.

Authorized Declarant Requirement

Importers need EORI number, clean compliance record, and financial guarantees. Ensures only professional, traceable traders participate.

Embedded Emissions Calculation

Direct emissions + indirect (for cement, fertilisers). Actual values preferred over default. Complex methodology requires rigorous documentation.

Carbon Price Deduction

Importers can deduct carbon prices paid in country of origin. Critical for countries with own carbon pricing (India CCTS, South Korea ETS, etc.).

50-Tonne De Minimis Threshold

Applies to iron/steel, aluminium, fertilisers, cement (NOT electricity, hydrogen). Reduces compliance burden for very small consignments.

Emission Reporting & MRV

Track embedded emissions across imported products (cement, iron/steel, aluminium, fertilisers, hydrogen, electricity). Monitor CN code-level reporting and Authorized Declarant status.

Hotspot Identification & Adjusted MACC

Cross-map embedded emissions with EU ETS allowance prices, CBAM certificate costs, and carbon prices paid in countries of origin. Identify highest-exposure product lines.

Decarb Planning

Best-fit supplier decarbonisation strategies to reduce embedded emissions. MACC sheets adjusted for CBAM Factor schedule (97.5% in 2026 → 0% by 2034) and increasing exposure.

Incentive Management

Track carbon price deductions for prices paid in origin countries. Manage documentation for third-country carbon cost claims.

Compliance & Forecasting

Multi-year exposure modelling as CBAM Factor tightens and free ETS allowances phase out. Model certificate procurement costs under different import volume scenarios.

Market Watch

Track EU regulatory updates, CBAM Factor schedule, ETS allowance pricing, sector-specific implementation, and cross-reference with origin-country carbon markets.

Impact on Global Exporters

CBAM creates real economic exposure for exporters in steel, aluminium, cement, fertilisers, and hydrogen. Companies in India, Canada, and other jurisdictions with domestic carbon pricing may claim deductions — but only if carbon prices are effectively documented. Exporters who fail to plan face rising costs as the CBAM Factor phases in, with 100% liability by 2034.

Frequently Asked Questions

EU CBAM — Common Questions

Answers to the most common questions about the EU Carbon Border Adjustment Mechanism, reporting requirements, and compliance obligations.

What is the EU Carbon Border Adjustment Mechanism (CBAM)?

CBAM is the EU's landmark regulation that puts a carbon price on imports of certain goods into the EU. It ensures that imported products face the same carbon costs as EU-produced goods, preventing "carbon leakage" where production shifts to countries with weaker climate policies. It entered its transitional reporting phase in October 2023 and moves to the definitive phase in January 2026.

Which sectors does CBAM cover?

CBAM covers 6 carbon-intensive sectors: iron & steel, aluminium, cement, fertilisers, electricity, and hydrogen. These sectors were selected because they have the highest risk of carbon leakage. The scope may expand to additional sectors over time to eventually cover all EU ETS sectors.

Who must comply with CBAM?

EU importers of CBAM-covered goods must register as "authorised CBAM declarants" with their national authority. They must report the embedded emissions in their imports and, from 2026, purchase CBAM certificates to cover those emissions. Non-EU producers exporting to the EU are also impacted as they must provide emissions data to their EU buyers.

How are CBAM certificates priced?

CBAM certificate prices mirror the weekly average EU ETS allowance auction price. This ensures imported goods face the same carbon cost as EU-produced goods. If the exporting country already has a carbon price, importers can claim a reduction to avoid double-counting. Free EU ETS allocations will phase out gradually as CBAM phases in fully by 2034.

What changed in 2026 with the definitive CBAM phase?

From January 2026, the financial obligations begin. Authorised declarants must purchase and surrender CBAM certificates corresponding to the embedded emissions in their imports. The transitional phase (2023-2025) only required quarterly emissions reporting. The definitive phase makes it a financial compliance obligation tied to the EU ETS carbon price.

How does CBAM affect non-EU exporters?

Non-EU producers must provide accurate embedded emissions data to their EU buyers. Countries like India, Turkey, and China — major exporters of CBAM-covered goods — are particularly affected. Many are accelerating their own domestic carbon pricing to allow their exporters to claim CBAM deductions for carbon costs already paid at home.

How can Climate Decode help with CBAM compliance?

Climate Decode's TerraNova platform helps both EU importers and non-EU exporters navigate CBAM. For importers: embedded emissions calculation, CBAM certificate management, and compliance reporting. For exporters: emissions data preparation, carbon price exposure analysis, and strategic decarbonisation planning to reduce CBAM liabilities.
