Abstract
This document specifies calculation methods 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. This document applies to plants that produce mainly carbon steel. It can be used by companies using EAF to manufacture 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.
This document supports steel producers to establish CO2 emissions attributable to a site.
Conversion to energy consumption and to consumption efficiency can be obtained using Annex A.
