This part of ISO 14404 specifies calculation methods for the carbon dioxide (CO2) intensity of plant
where steel is produced through a blast furnace.
NOTE The steel plant is generally called “the integrated steel works”.
It includes boundary definition, material and energy flow definition and emission factor of CO2. Besides
direct source import to the boundary, upstream and credit concept is applied to exhibit the plant
CO2 intensity.
This part of ISO 14404 supports the steel producer to establish CO2 emissions attributable to a site. This
part of ISO 14404 cannot be used to calculate benchmarks or to compare CO2 intensities of production
processes that are operated inside the site.
Conversion to energy consumption and to consumption efficiency can be obtained using Annex A.
