This article guides you through how to complete the CBAM communication template for installations producing goods with the following CN codes:

7205, 7208-7217, 7219-7223, 7225-7229, 7301-7311, 7318, 7326.

Download the communication template: CBAM Communication template for installations

The communication template includes several tabs. Below you will find guidance in the order in which we recommend completing them. You can follow the sequence or jump to specific tabs if you have specific questions.

Throughout the Workbook all dark yellow are mandatory cells, light yellow cells are optional.

⬇Tab A_InstData

1. Input the start and end dates for the reporting period. Ideally, it should cover 12-month period and match the same timeframe as the data used to complete this template.

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).

⬇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)

Summary_Communication

1. Here you just need to send this tab to your clients, to do this just go to “Review” and then click “Unprotect Sheet”.

2. Copy this tab to a new Excel workbook

Select all cells in this tab:

You can do this with the command ctrl +A, plus ctrl+A again until all cells are selected.
Copy the cells with the command ctrl+C
Then paste the cells into a new workbook.
Click on the "paste" icon that has appeared and choose "Paste values".
Again click on the "paste" icon and select "Paste Formatting"
You can now save this workbook and send it to your clients.

⬇Implementing a Monitoring Methodology for Steel Products

From 1 January 2026 onwards, importers will have to bear a “CBAM obligation” in the form of certificates, which they purchase at the average price of EU ETS allowances, for every CBAM good imported into the EU. Monitoring should be performed throughout the reporting period. Therefore, you must be prepared to provide your CBAM data and develop a monitoring methodology at your installation as soon as possible, as described in this guidance article.

Develop a methodology that is as straightforward as possible using the best and most reliable data sources, as outlined in section 6.4.4 of the Installation Monitoring Methodology. The methodology should include written procedures with clear instructions, specifying data locations and the assigned roles and responsibilities.

Extra information:

Aggregated Goods Category	Relevant precursors
Steel products	Ferro alloys (FeMn, FeCr, FeNi), pig iron, DRI, crude steel, iron or steel products (if used in the process)

Aggregated good	Monitoring requirement
Steel products	Main reducing agent used in precursor production (if known) Content of alloys in steel expressed as: Mass % of: Mn, Cr, Ni, and total of other alloying elements Tonnes of scrap used for producing one tonne of product % of scrap that is pre-consume

Guidance

What is a monitoring methodology?

A monitoring methodology suply all the required information for your CBAM data collection. The monitoring methodology document (MMD) ensures that monitoring activities are consistently conducted year after year. The MMD acts as a "rule book" for all your installation staff and for training new staff involved in the monitoring process.

You must document methods related to data collection, maintenance and calibration of meters, descriptions of various calculations and formulas used, sources of standard values, and any quality assurance methods.

The methodology should be accompanied by written procedures that include:

Managing responsibilities and competency of personnel: detailing roles and assigning responsibilities to key staff members
Data flow and control procedures
Quality assurance measures
Estimation methods for substituting data when data gaps are identified
Regular reviewing the monitoring methodology
Procedure for regularly reviewing and updating the list of products and precursors produced or imported by an installation

How do I create a monitoring methodology?

1. Define your installation's boundaries

A production route is a specific technology used in a production process to produce goods as defined in the Implementing Regulation and in Table 1.

You can consult it in the Implementing Regulations and in Table 1.

Begin by listing names and quantities of all goods:

Stationary physical units (used in the production processes)

Inputs: raw materials, fuel, heat, electricity.

Outputs: produced goods, by-products, waste, heat, electricity, waste gases, and emissions.

Emissions for your installation

You can collect this data via metering data, invoices, production protocols or stock determination.

Identify which goods produced at your installation are covered by CBAM and to which aggregate goods category the goods belong.

Consult to Table 1 of the Implementing Regulations in Section 2 of Annex 2. Each added good will require a production process to be defined. You can also refer to Table 1 of this article.

Identify relevant production processes and routes producing your CBAM goods.

List the relevant process units, inputs, outputs, and emissions.
Drawing a schematic of your installation might be helpful.
Monitor the emissions of such units separately and attribute them to the production processes based on the amount of heat consumed in each process.

The system boundaries may differ depending if your installation make:

Single category of good:
The installation boundary and production process system boundary for monitoring and reporting embedded emissions are the same.
Several different unrelated categories:
You must define separate production process system boundaries within the single installation.
Same category of good by different production routes:
As an operator, you can define either a single production process system boundary or separate production process system boundaries of the different production routes. If you choose to assign separate processes, the embedded emissions for the goods will be calculated individually for each production route.
Category of complex good and its precursor:
Where this precursor is entirely used to produce the complex good, you may define a joint production process system boundary within the installation.
Non-CBAM goods
You need to define only production process system boundaries for the production processes relating to CBAM goods within the installation. However, it is recommended to also define an additional production process system boundary for the non-CBAM good to ensure that all relevant emissions have been covered, this as an improvement over the basic requirements.
Two or more goods from specific product groups , during the transitional period:
For example, sintered ore, pig iron, FeMn, FeCr, FeNi, DRI, crude steel, and iron or steel products. You can monitor and report embedded emissions by defining one joint production process (the 'bubble approach'), as long as none of the produced precursor materials are sold separately.

Section 3 of Annex II in the Implementing Regulation defines the system boundaries for direct emissions from various steel production production routes as follows:

All CO2 emissions from combustion of fuels and process emissions from flue gas treatment, related to production steps applied at the installation, including, but not limited to: re-heating, re-melting, casting, hot rolling, cold rolling, forging, pickling, annealing, plating, coating, galvanizing, wire drawing, cutting, welding and finishing of iron or steel products.

You may included in your installation's system boundaries the following production steps:

Raw material preparation: including pre-heating, re-melting and alloying
Forming processes for basic steel products: all forming process steps, including casting, hot and cold rolling, shaping by forging, wire drawing
Finishing activities: all finishing steps including surface treatment (such as pickling, annealing, plating, coating, galvanizing) and further fabrication (cutting, welding, finishing)
Emissions control: for treating releases to air, water or ground

2. Define your reporting period

The reporting period is the time during which your parameters will be monitored. Usually, this reporting period corresponds to one European calendar year, but the minimum duration is 3 months.

3. Identify the parameters that need to be monitored

Parameters include data relating to direct and indirect emissions as well as precursors.

Direct emissions may include:

Emissions from stationary fuel combustion processes including:

Coke
Waste gases (direct from the process or from other sources of waste gases in the steelworks
Fossil fuel inputs used both for combustion and as a reducing agent (coal, coke, fuel oils, natural gas, coal)

Emissions from reduction of iron and steel by reducing agents.

Emissions from thermal decomposition of carbonate materials (e.g. coke and natural gas).

Emissions from carbon content of scrap, alloys, graphite, and other carbon containing materials entering the process.

Emissions from emissions control (e.g. carbonate materials, such as soda ash, used for acidic flue gas cleaning).

Other process emissions including:

Graphite electrodes and electrode pastes.

Process materials like: lime, limestone and other additives, other fuels (biomass, biogas), carbon, contained with the ferrous scrap and alloys entering the process.
Combustion of fuels and process emissions from flue gas cleaning (depending on the different combination of production processes)

Direct emissions can be monitored using two approaches.

Calculation-Based Approach: In this method, you will determine the quantities of fuels and relevant materials consumed and identify the corresponding emission factors.
Measurement-Based Approach: In this method, you will measure the concentration of greenhouse gases and the flow of flue gases for each emission source.

Direct emissions related to heat flows must also be monitored. These emissions can be tracked by quantifying heat consumption, whether produced at the installation or received from another installation, and assigning the heat to each process.

Indirect emissions

Indirect emissions from electricity used during production processes must be monitored, regardless of where the electricity is produced. This involves quantifying the electricity consumed in each production process. Electricity produced on site should be monitored like other direct emissions. In the steel sector, indirect emissions are reported only during the transitional period.

You should monitor the precursors relevant to each production process. The monitoring parameters depend on the location where the precursors are produced. Refer to Table 1 to find the precursors relevant to your installation.

If a precursor is produced within your installation, you complete all relevant monitoring by tracking the direct and indirect emissions as described above.

If you purchase a precursor, you must request the relevant data from the installation that produced it. This data should include:

Identifying information of the installation where the precursor was produced
Specific direct and indirect embedded emissions of the precursor
The production route
The reporting period
information regarding carbon prices, if applicable

In both scenarios, you need to monitor the quantities of precursors consumed. The guidelines for monitoring precursor-related data are detailed in section E of Annex III of the Implementing Regulation. Additional parameters for steel products include those in the Table 2.

4. Determine the methodology to monitor each parameter

For the quantities of fuels and materials used (including precursors):
you can either use measurement instruments that track consumption during the reporting period (such as weighing belts, flow meters, or heat meters) or calculate the amounts based on purchase records and stock measurements at the end of each period.
For emission factors:
You can either choose a “standard value” from applicable literature or from Annex VIII to the Implementing Regulation, or you can determine them based on laboratory analyses, for which the Implementing Regulation provides further rules in section B.5 of Annex III.
For continuous measurements of emissions, heat flow, and electricity:
you also need to specify the instruments to be used, along with the relevant calibration and maintenance procedures.
If you lack other methods to monitor the embedded emissions of your goods:
Especially if the producer of your precursors used does not supply the required data, you can use the default values for embedded emissions of CBAM goods provided by the European Commission. You can find a list of goods with available default values on the European Commission’s dedicated website. These default values cover all relevant precursors.

5. Compile your information

You have finished developing your installation’s monitoring methodology. Next, compile all the collected information into a single written document. Ensure that the documentation adheres to the Monitoring Principles outlined below. Additionally, include a diagram of your installation showing the locations of all necessary instruments and sampling points. Be sure to record the names and contact details of those responsible for data collection and monitoring.
