Waste Gas
If you produce pig iron and/or crude steel, you must attribute emissions from the generated waste gas. These emissions contribute to the direct emissions.

Right-click on the screen and select CBAM > Production Process
Select any good under the aggregated goods categories of Pig Iron or Crude Steel
Select the Measurement Unit
Indicate the amount of waste gas generated in the specified unit
Input the Waste Gas Emission Factor
According to equation 54, input the standard emission factor of natural gas 56,1 tCO2/TJ.
Click Next
Click on the black dot at the edge of the Production Process and drag the line to connect it to one of the black dots on the Self Electricity and/or Production Process
Select Waste Gas as the type of output
Enter the Quantity of Waste Gas you want to send to the Self Electricity unit
Click Add
Emissions are calculated based on the amount of waste gas exported to each process
In the below example, emissions from the production process are calculated using equation 54, taking into account the amount of waste gas exported to each process, the standard emission factor of natural gas (56.1 tCO2/TJ), and the correction factor (Corrη = 0,667).
Simultaneously, emissions from the waste gas imported to each process are calculated using equation 53, where the correction factor is not applied. Hence, the attributed emissions are higher than those deducted from the originating process (blast furnace).
