BS ISO 14404-1:2013

1   Scope This part of ISO 14404 specifies calculation methods for the carbon dioxide (CO 2 ) 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 CO 2 . Besides direct source import to the boundary , upstream and credit concept is applied to exhibit the plant CO 2 intensity. This part of ISO 14404 supports the steel producer to establish CO 2 emissions attributable to a site. This part of ISO 14404 cannot be used to calculate benchmarks or to compare CO 2 intensities of production processes that are operated inside the site. Conversion to energy consumption and to consumption efficiency can be obtained using Annex A.
