ISO 14404-1

Description / Abstract: 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. ISO 14404 cannot be used to calculate benchmarks or to compare CO₂ intensities of production processes that are operated inside the site.

Conversi9on to energy consumption and to consumption efficiency can be obtained using Annex A.
