Abstract

ISO 14404-2:2013 specifies calculation methods which companies using EAF to manufacture steel can use to evaluate the total annual carbon dioxide (CO₂) emissions and the emission factor of CO₂ per unit of steel production of the entire steel production process. ISO 14404-2:2013 is applied to the plants that produce mainly carbon steel.

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.

ISO 14404-2:2013 supports the steel producer to establish CO₂ emissions attributable to a site. ISO 14404-2:2013 cannot be used to calculate benchmarks or to compare CO₂ intensities of production processes that are operated inside the site.
