CBAM embedded emissions

Specific embedded emissions (tCO₂e per tonne) of a product at your installation, calculated with the method of Implementing Regulation (EU) 2025/2547, compared with the Commission default values, with the data for the operator’s emissions report (Annex IV). A data pack, not a CBAM declaration.

New here? How this works

You will need: For one product made at one installation: the production quantity, the fuels and electricity used to make it, and its CN code (the customs code on the invoice). Ask your plant or energy manager if you do not have them.

Choose the sector and type the CN code of the product (first 4 to 8 digits of the customs code).
Enter how much you produced, in tonnes unless the box says otherwise.
Add the fuels burned and the electricity bought. Skip the technical boxes you do not know; the standard values are used.
Press Calculate. The result is the embedded emissions per tonne, ready for your EU customer.

Example values are already filled in. Press Calculate once to see what a result looks like, then replace them with your own.

Operator and installation (Annex IV, point 1)

Operator nameYour company’s legal name as on the EU declaration.Operator registration numberOptional. Fill in only if the EU importer or the CBAM Registry gave you a number.Installation nameThe plant or factory where the good is made.Installation ID in the CBAM RegistryOptional. Fill in only if you already have one from the CBAM Registry.UN/LOCODE of the locationOptional. Five-letter UN code of the town, for example TRIST for Istanbul.Full address (English)Optional. The plant’s address in English.Coordinates of the main emission sourceOptional. Latitude and longitude, for example 41.01, 28.97. Copy them from a map.

Good and period

Reporting yearThe calendar year your numbers cover.SectorThe industry of the good. If unsure, check the first digits of its CN code.CN code (at least 4 digits)The customs tariff code of the product, found on the invoice or customs declaration. Four digits are enough to start.Country of productionWhere the good was made. Türkiye for your own plant.Activity level: quantity of the good in its functional unitTonnes of the good; for cement CN 2523 10/21/29/90 tonnes of clinker contained; for fertilisers 2808 00 00, 2814 and 3105 kilograms of nitrogen (Art. 4). Only sellable goods count: not off-spec products, by-products or scrap (Annex II F).Content per tonne of good: t clinker/t (cement) or kg N/t (fertilisers), optionalConverts the result from the functional unit to tonnes of good (Annex III B, equations 64 and 65). Ranges of composition may not be wider than 10 %.Total output of all goods sharing the process, same functional unit, optionalIf the process makes several goods, emissions are attributed by functional unit (Annex III A.2): this good's share = activity level ÷ this total. Chemicals and fertilisers use a molar ratio: not implemented.

Direct: fuels burned (standard method, Annex II B.3.1.1)

Fuels burned at the plant to make the good. Enter the total for the period, in the unit shown.

SourceQuantitytonneYour NCV (GJ/t), blank = standard valueOptional. Only if your lab or supplier gave the heating value. Blank uses the standard value.Oxidation factor (0 to 1)Share of the fuel that burns completely. Use 1 unless you measured it.Biomass fraction (0 to 1), zero-rated only if the B.3.3 criteria are metShare of the fuel that is biomass (wood, biogas). Use 0 for fossil fuels.

Direct: process emissions from carbonate decomposition (Table 3, input based)

Only if the process breaks down limestone or similar. Skip otherwise.

Direct: process emissions from other materials, iron and steel (Table 5)

Advanced, iron and steel only. Skip otherwise.

Direct: mass balance method (Annex II B.3.2), your carbon contents

Advanced. Only if you track carbon in and out of the process. Skip otherwise.

Direct: other gases and measured CO₂ (Table 6 GWPs)

Advanced. Only for measured gas emissions such as N₂O or PFCs. Skip otherwise.

Measurable heat imported or exported (Annex III A.2.2)

Only if you buy heat from or sell heat to another plant. Skip otherwise.

Waste gases imported or exported (Annex III A.2.3), energy content in TJ

Only if waste gases are passed to or from another plant. Skip otherwise.

Indirect: electricity (Annex II D, Art. 9)

Electricity bought for the plant. Your electricity bill gives the kWh.

SourceQuantitykWhEmission factor of this source (kg CO₂e/kWh)Use the factor the CBAM rules allow (importer defaults: Annex II of Implementing Regulation (EU) 2025/2621). Several sources are weighted by consumption (Art. 9).Supplier and country of originOptional. Who you buy the electricity from and in which country.

Precursor materials (Annex II E, Art. 14, 15; Annex III B)

Materials you bought in that were already made with emissions (for example steel rods for screws). Skip if none.
