EU CBAM Carbon Tax Calculator
Carbon Border Adjustment Mechanism Estimator
Estimate the cost of the EU Carbon Border Adjustment Mechanism (CBAM) for your imports. See how CBAM costs will increase from 2026 to 2034 as free allowances are phased out, and calculate credits for carbon prices already paid in the origin country.

What is the EU CBAM?
The Carbon Border Adjustment Mechanism (CBAM) is a carbon tariff on imports into the European Union. It ensures that the carbon price paid for EU-produced goods also applies to imports, preventing "carbon leakage" — the relocation of production to countries with less stringent climate policies.
CBAM Timeline
- October 2023 – December 2025: Transitional period (reporting only, no financial obligation)
- January 1, 2026: Definitive phase begins with 2.5% CBAM obligation
- February 1, 2027: First CBAM certificate purchases
- 2026-2034: Gradual phase-in as EU ETS free allowances are eliminated
- January 1, 2035: Full CBAM application (100% carbon cost)
Which Products Are Covered?
CBAM initially covers six carbon-intensive sectors:
- Cement: Including clinker and Portland cement
- Iron and Steel: Both basic oxygen furnace (BOF) and electric arc furnace (EAF)
- Aluminum: Primary and secondary aluminum products
- Fertilizers: Nitrogen-based fertilizers
- Electricity: Direct electricity imports
- Hydrogen: Green, blue, and grey hydrogen
How Is CBAM Cost Calculated?
CBAM Cost = Quantity × Embedded Emissions × EUA Price × Phase-In Rate
Importers can deduct any carbon price already paid in the country of origin (e.g., a domestic carbon tax or emissions trading system cost). This prevents double taxation.
Impact on Global Trade
CBAM is expected to significantly affect trade in carbon-intensive goods with the EU. Countries with high carbon intensity in manufacturing (China, India, Turkey, Russia) will face the highest additional costs. Countries with existing carbon pricing mechanisms will see lower CBAM bills due to the carbon price credit.
Frequently Asked Questions
When do I actually need to start paying CBAM?
The financial obligation starts January 1, 2026, with 2.5% of the carbon cost. The first certificate purchases begin February 1, 2027. Until then (2023-2025 transitional period), only reporting is required.
Can I get a credit for carbon taxes paid abroad?
Yes. If a carbon price has been effectively paid in the country of origin (through carbon taxes, emissions trading systems, or other mechanisms), that amount can be deducted from the CBAM obligation.
What is the current EU ETS carbon price?
The EU ETS carbon price fluctuates based on market conditions. As of early 2026, it ranges between €65-90 per tonne of CO₂. The CBAM certificate price is linked to the weekly average EU ETS auction price.
