BS ISO 14404-1:2013

This standard BS ISO 14404-1:2013 Calculation method of carbon dioxide emission intensity from iron and steel production is classified in these ICS categories:

• 77.080.01 Ferrous metals in general
• 13.020.40 Pollution, pollution control and conservation

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. 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.
