Steps to reduce greenhouse emission gases (CO₂) are increasingly becoming a matter of priority for the industry, particularly for the iron and steel industry, which is the largest consumer of the world’s generated energy on a global basis. This paper outlines the principal factors necessary for evaluating CO₂ emission rates as the basis for comparing the net CO₂ emission figures for different iron and steel production routes from cradle to grave. Calculations show that CO₂ emissions considerably depend on the assumptions for the system borders and some external factors, e.g. the specific emission values for grid electricity.
