⬇Tab A_InstData
2. Enter information about the installation. Here you can find your UN/LOCODE. If you do not know the latitude and longitude of your facility, you can check them on Google Maps.
3. Fill out the required information in the “Verifier of the report” section, this is optional until 2026.
4. Enter your Aggregated goods categories and select “iron or steel products” from the drop-down list.
5. Enter your production processes
- You can add one row for each of the products you produce. You can also choose to group similar products together:
- multiple products within that fall within a single CN code
- multiple products across CN codes, provided the products are similar
- If you produce an intermediate product that is fully consumed in producing your final product (i.e. you produce steel rods that you then use to produce steel screws), you don't need to list the intermediate product as a separate row (instead, change "only direct production" to "iron or steel products"). If however, some of that product is not used to produce your final product (i.e. some of it is sold directly, or used to produce non-CBAM goods), you need to list it as a separate row.
6. Add any CBAM products you purchase as precursors and add one row for each supplier.
⬇Tab B_EmInst
1. Add the data for the fuels you combust:
- Exclude fuels used in vehicles.
- You can use the default values from Annex D of the CBAM installation guidance or your own NCV and EF values.
- Ensure your units are consistent.
- Don't enter any electricity data. If you can't clearly distinguish between electricity and non-electricity data (for example you have a CHP plant, or you fuel a process that makes waste gas that is then used to produce on-site electricity), you can still enter that full data here (we'll allocate the correct portion to electricity later on).
2. If you have process emissions (e.g. anode consumption etc.) add them as well
3. If you have PFC emissions, scroll down to add them (or check our detailed step-by-step guides)
4. If you produce nitric acid, scroll down to add N2O process emissions. A continuous monitoring system is compulsory for N2O emissions.
⬇Tab D_Processes
1. Enter the amount of product you produced during a 12 months period.
2. Divide the quantity into the amount sold ('produced for the market'), amount consumed in other (CBAM) production processes, and amount consumed in producing non-CBAM goods.
Make sure you repeat this step for each of the goods you produce (scroll down to find input areas for your other goods)
3. Enter the total directly attributable emissions.
To determine the directly attributable emissions:
1. Check the sum of all emissions listed in column AU ("CO2e fossil (t)") of Tab B_EmInst.
2. Distribute the emissions between the various goods you produce.
3. Exclude any emissions resulting from the on-site production of electricity.
Make sure you repeat this step for each of the goods you produce (scroll down to find input areas for your other goods)
4. Provide the information about your electricity consumption.
- Enter the annual purchased and/or generated electricity in MWh for each process.
- Divide your total annual electricity consumption between each of your goods based on the consumption of electricity by each good.
- Enter the emission factor for your electricity and its source. Your options are:

- IEA default emission factors: CBAM - EU Grid Emission Factors.xlsx.
Note: If you have a CHP unit, generate your own electricity, or import/export waste gases, we will revisit this sheet when we complete tab F_Tools.
⬇Tab E_PurchPrec
1. Enter the quantity of product you purchased over the 12-month period.
- Remember to repeat this step for each good you purchase (scroll down to find input areas for your other purchased goods.)
2. Divide the quantity into the amount used as an input into each of your CBAM goods, as well as any amount used in producing non-CBAM goods
- Remember to repeat this step for each good you purchase for each supplier.
3. Add the specific embedded emissions for each of your purchased precursors.
You can obtain this data from your suppliers, who should provide you with their own summary communication sheet.
There are two cases where you don’t need to use real data from your suppliers:
- If the emissions from your purchased precursors contribute less than 20% to your total emissions. You can estimate these emissions using default values to check if this applies (though this is unlikely for steel goods).
- If you are providing data for your customers to use in their April 2024 and/or July 2024 declarations (after this date, primary data is mandatory).
In these cases, you can enter in these cells default values. Otherwise, you will need to use specific data from your suppliers. Contact your suppliers now to ensure they can provide the necessary data when you need it. You can also contact us to help you with data collection.
⬇Tab F_Tools
This is an optional tab. Only provide information in this tab if:
- You have a CHP/cogeneration unit, and you want to assign the emissions arising from this CHP unit between the heat and electricity outputs
- You currently pay a carbon price on your goods in your country.
⬇If you have a CHP/cogeneration unit:
1. Enter the total fuel input, and heat and electricity output, from your cogeneration unit
2. Enter the emissions resulting from your cogeneration unit.
- If you have a continuous monitoring system, enter the emissions measured directly.
- Alternatively: Calculate emissions by multiplying the fuel quantity by its emission factor
- Note: Refer to Annex D of the CBAM installation guidance if you don't have a measured emission factor for your fuel.
- If you have emissions from flue gas cleaning, enter those (if not already included in your continuous monitoring system).
This will give you emissions information for your heat and for your electricity
3. Return to Tab D_Processes and update with information from your co-generation calculations.
Add emissions from heat used in each product to the directly attributable emissions for that product.
-
Add emissions from generated electricity used in each product to the directly attributable emissions for that product.
Divide the total emissions from generated electricity by the total electricity generated to get the emission factor.
Change the Source of the emission factor to D.4.2
If you use a mix of generated and purchased electricity, enter a weighted average emission factor, and set the Source of the emission factor to 'Mix'
⬇If you pay a carbon price:
1. Specify the currency in which the carbon price is paid. This could be the currency of your installation's country or the country where the installation of your purchased precursor is located, if that’s where the price is paid.
2. Indicate the share of emissions covered by the carbon price, along with the carbon price and any rebates.
Enter the carbon price per tonne of emissions in your local currency and any rebate received per tonne of emissions, such as free allocations.
⬇Tab C_Emissions&Energy
This tab is mainly for you to verify the accuracy of the data entered in other sections.
1. The only mandatory part is to select the options that best describe the quality of your data, and the level of assurance that this data is correct.
All other contents are optional and if you like, you can skip to the next part.
2. Enter the total fuel you used in your CBAM goods, your on-site electricity production and for your non-CBAM goods, and make sure it sums to the total you expect.
3. Enter your electricity emissions calculated in tab D_processes. You have to multiply the quantity of electricity by the emission factor, for each of your products.
Notes:
- Have you correctly assigned your direct and indirect emissions in tab D_Processes, without double counting, and without forgetting any emission sources?
- Do your direct and indirect emissions in tab D_processes add up to the total emissions?
- This data is simply for you to check the accuracy and completeness of your data you will not used it elsewhere.
⬇Summary Tabs
Summary_Processes
If you pay a carbon price, enter information here. Otherwise there is nothing to do in this tab.
Summary_Products
1. In this tab you will enter each of your CBAM goods, their CN codes and public-facing names.
- Enter at least one row for each of your "production process from which the products arise" (If you'd like to report multiple products/brands to your customers using the same data you can duplicate a "production process").
- On the column "CN Codes" enter the CN code for the good.
- Add a public facing name for each good.
2. Add product composition information to each of your goods
Scroll to the right then complete the relevant product composition information and if known the main reducing agent and the heat number(s)
