Description / Abstract:
This part of ISO 14404 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. This part of ISO 14404 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.
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.
