How to calculate your CBAM cost exposure
As an importer of CBAM goods to the EU, you calculate costs using the CBAM formula. Here's an overview, in plain language, of what goes into it.
Emissions Intensity
The producer's direct embedded emissions intensity (tCO₂e/t) of their CBAM goods. For aluminium and steel, only direct emissions apply; for fertiliser and cement, both direct and indirect. Without third-party verification, punitive country-level default values are used instead..
CBAM Benchmarks
The emissions threshold above which CBAM costs kick in. Set by EU benchmarks or installation defaults, and decreasing over time as free EU ETS allowances are phased out. The lower the benchmark, the higher the cost exposure.
Carbon Price Paid Overseas
Any carbon price already paid in the country of origin covering the emissions intensity of the goods. This is deducted from the net CBAM obligation, preventing double-counting and reducing the final cost for producers in countries with their own carbon pricing.
Phase-in Schedule
CBAM costs phase in gradually from 2026 to 2034 as free EU ETS allowances are withdrawn. The percentage applied increases each year, meaning exposure grows significantly over time even if emissions intensity stays flat.
Running this formula manually is HARD
Accurately calculating CBAM costs across multiple suppliers, CN codes, and production routes is both difficult and time-consuming to do manually. Our CBAM Calculator automates default values, benchmarks, and phase-in rates, letting you model costs per tonne and compare suppliers in seconds, not spreadsheets.
HOW IT WORKS
From inputs to cost clarity in four easy steps
1. Select your inputs
Enter your CN code, country of origin, supplier, production route, and tonnage. Everything you need to model a specific trade in seconds.
2. Automatic data lookup
The calculator pulls in global default values, supplier emissions intensities, EU benchmarks, and phase-in adjustments. No manual research needed.
3. Model scenarios
Adjust assumptions around benchmarks, emissions intensity, and carbon price to stress-test your exposure. Compare suppliers side by side to inform procurement decisions.
4. Get instant results
See your annual CBAM cost per tonne from 2026 to 2034, total landed cost impact, and the difference between using default values and primary supplier data.
