Work out your embedded emissions from your own data.
If you export goods covered by the Carbon Border Adjustment Mechanism (CBAM), the embedded emissions of your product have to be declared. This tool derives an approximate specific embedded emissions (SEE) figure from your installation’s fuel, process and electricity data, and lets you carry the result straight into a comparison against the regulatory default.

Derives an approximate specific embedded emissions (SEE) figure from your installation data. The result is carried into the field above.
What do you produce?
The category determines which precursors are required (Guidance No. 3, Table 4-2).
The denominator of the formula (AL). The product itself, not the inputs.
Enter the production quantity to continue.
Fuel consumption
Fuels burnt in kilns and boilers. Leave empty and continue if there are none.
Where your installation also makes goods outside CBAM, charging all the fuel to the CBAM product overstates the estimate. Left blank it counts as 100%. Process emissions are not affected — calcination belongs to the product that caused it.
Process emissions
Either Method A (carbonate input) or Method B (oxide output) — do not use both, that double-counts.
There is no standard factor for carbon anodes in primary aluminium — MRR Annex IV §7(B) requires the mass balance methodology. Use the “carbon-bearing input (pure C)” row with the carbon fraction from your anode analysis.
Energy and flows
Electricity consumed is required. Tick the others only where they apply to your installation.
Enter the grid emission factor for the country of origin. Where a direct technical link or a power purchase agreement exists, an actual factor may be used (Methodology Act, Annex III).
Measurable heat
Where the fuel mix is unknown, the default of 62.3 applies (natural gas at 90% boiler efficiency). Heat recovered from electricity-driven processes and from nitric acid production is not accounted.
CBAM Guidance No. 3 §4.8.2 — EFheat,default = 62.3 t CO₂e/TJ
Waste gases
Enter the energy content as volume × net calorific value. Imports are multiplied by the natural gas factor; exports also carry the 0.667 efficiency correction.
On-site electricity generation
Electricity generated inside the process boundary is deducted. The factor is determined under Methodology Act, Annex II section D.
Precursors
For each precursor, enter its mass and its own SEE. Direct and indirect are carried separately.

Most companies searching for CBAM software actually have one of three distinct needs. Knowing which one you are in saves a lot of time before you start collecting quotes:
- 1 · Looking up a value: “What is the default value for my CN code and country of origin?” This needs no software — the default value lookup does it free, with no sign-up.
- 2 · Calculating embedded emissions: “How do I establish my own installation’s actual figure?” This is a data-collection and calculation exercise: installation boundaries, activity data, heat and electricity flows, precursors. The tool on this page produces exactly that, at screening level. What decides the outcome is not software but the quality and traceability of your data.
- 3 · Reporting and verification: getting the calculation verified by an accredited verifier and the declaration to your importer. Software alone will not carry you here; the file has to be built so that it survives verification.
To be explicit: EPDlogy is not a software company, and this tool is not software. No registration is required and nothing is hidden behind a quote form; the calculation runs directly in your browser. What it does is narrow and honest: turn your installation data into a screening estimate and let you benchmark it against the official default.
What this tool does and does not calculate
It calculates
- Direct emissions from fuel combustion (33 fuels, using the Commission’s standard factors)
- Process emissions — carbonate input (Method A) or oxide output (Method B), cement clinker, iron & steel process materials
- Measurable heat imported and exported, and the waste gas correction
- Indirect emissions from electricity consumed, less electricity generated on site
- Emissions carried by purchased precursors — direct and indirect kept separate
- A fuel split for installations that also make goods outside CBAM
It does not calculate
- N₂O and PFC emissions. N₂O dominates nitric acid production and PFCs arise in primary aluminium; both need their own monitoring methods. The tool warns you when you pick those categories — the estimate will sit below the real figure.
- Sampling and laboratory analysis rules. It uses standard factors and does not replace an installation-specific analysis.
- Sub-installation attribution and multi-process sites. It assumes a single production process; the Commission’s template supports up to four.
- Oxidation and conversion factors. Complete combustion is assumed.
- The biomass fraction of mixed fuels. A fuel counts as wholly fossil or wholly biomass.
- The free-allocation adjustment and any carbon price paid in the country of origin. Neither is included in the certificate cost.
In short, this is a screening tool. It does not substitute an accredited verifier report and cannot be used in a CBAM declaration. Its purpose is to show you, in a few minutes, what collecting your real data would be worth.
Using your actual data removes the mark-up.
Reporting with verified installation data lets you use your own emissions intensity instead of the default plus its mark-up — which may turn out lower or higher than the default. Get in touch for emission accounting and verification readiness.
