ISO 14404 part 4 provides the guidance for calculating the CO2 intensity at steel plants with all types of process routes, by defining the boundary, CO2 emission factors and the intermediate products for which upstream emissions are considered for all types of process routes. In particular, ISO 14404 part 4 provides the guidance to apply ISO 14404 family to following types of steel plants. ISO 14404 part 4 also includes Universal Calculation Sheet, which covers all relevant emission sources from ISO 14404-1, 2, 3, to assist the calculation of CO2 emissions.

  1. Steel plants with different process routes from ISO 14404-1, 2, 3 (7.2.1)

  2. Steel plants with more than one process route (7.2.2)

  3. Steel plants purchasing pig iron from the outside (7.2.3)

  4. Steel plants and rerollers purchasing part or all of crude steel from outside (7.2.4)

Moreover, ISO 14404 part 4 provides additional guidance to the entire ISO 14404 family for the following topics.

  1. Evaluation of exported slags

  2. Evaluation of by-product gas

  3. Evaluation of stock

  4. Selection of calorific values and emission factors for electricity and fuel

Conversion to energy consumption and to consumption efficiency can be obtained using Annex A.

While the use of the calculation result is outside Scope of this standard, appropriate applications and inappropriate application are recommended in Annex B.
