What is CBAM?
The Carbon Border Adjustment Mechanism is the EU's landmark policy to put a fair price on carbon emissions embedded in imported goods. Here's everything you need to know.
Understanding CBAM
The Carbon Border Adjustment Mechanism (CBAM) is a key element of the European Union's "Fit for 55" climate package. Established under EU Regulation 2023/956, CBAM aims to prevent "carbon leakage" — the risk that companies move production to countries with weaker climate policies, or that EU products are replaced by more carbon-intensive imports.
In practice, CBAM requires importers of certain carbon-intensive goods to purchase certificates that reflect the CO₂ emissions embedded in their products. This creates a level playing field between EU producers (who already pay for emissions through the EU Emissions Trading System) and foreign producers.
Why Does CBAM Exist?
Prevent Carbon Leakage
Without CBAM, EU climate policies could simply push production to countries with lower environmental standards, resulting in no net reduction in global emissions.
Level Playing Field
EU manufacturers pay for their carbon emissions through the EU ETS. CBAM ensures imported goods carry a comparable carbon cost, creating fair competition.
Drive Global Decarbonization
By attaching a cost to embedded emissions in imports, CBAM incentivizes non-EU producers to adopt cleaner production methods.
Support EU Climate Goals
CBAM is a central pillar of the EU's goal to reduce greenhouse gas emissions by at least 55% by 2030 under the European Green Deal.
CBAM Timeline
Transitional Phase
October 1, 2023 — December 31, 2025
During this phase, importers are required to submit quarterly CBAM reports detailing the embedded emissions of imported goods. No financial obligations apply yet — this period is about data collection, process building, and preparation.
Definitive Phase Begins
From January 1, 2026
The full CBAM mechanism takes effect. Importers must be registered as authorized CBAM declarants and purchase CBAM certificates to cover the embedded emissions of their imports. This is when the financial impact begins.
Full Phase-In
2026 — 2034
Free EU ETS allowances for CBAM sectors will be gradually phased out, reaching zero by 2034. This means CBAM certificate costs will progressively increase, making early preparation and cost optimization essential.
Which Sectors Are Affected?
CBAM currently covers six product categories defined in Annex I of Regulation 2023/956. If you import any of these goods into the EU, CBAM applies to you.
Cement
Iron & Steel
Aluminium
Fertilizers
Electricity
Hydrogen
Risks of Non-Compliance
Failing to comply with CBAM can have significant financial and operational consequences for your business.
Financial Penalties
Non-compliant importers face fines, and the penalties increase for repeated or prolonged violations.
Import Restrictions
Without authorized CBAM declarant status, you may face delays or be unable to import CBAM goods into the EU.
Default CO₂ Values
If you can't provide actual emission data, default values (typically much higher) are applied — significantly increasing your CBAM certificate costs.
Competitive Disadvantage
Companies that fail to prepare will face higher costs and operational disruptions compared to competitors who acted early.
How to Prepare
Whether you're just getting started or looking to optimize your existing approach, here are the key steps to CBAM readiness.
Assess Your Exposure
Identify which of your imports fall under CBAM, map your suppliers and countries of origin, and quantify the potential financial impact.
Set Up Data Collection
Establish processes to collect actual emission data from your suppliers. Engage early — supplier cooperation is critical for accurate reporting and lower costs.
Prepare Your Application
Register as an authorized CBAM declarant. Prepare all required documentation and ensure your internal processes meet regulatory requirements.
Optimize Strategically
Develop scenarios for cost management. Consider supply chain adjustments, alternative sourcing, and integration with your broader sustainability strategy.
Train Your Team
Ensure everyone involved — from procurement to finance to compliance — understands their role in CBAM data collection and reporting.
