This document specifies guidelines and requirements for conducting life cycle inventory (LCI) studies of steel products reflecting steel's capacity for closed-loop recycling, including:

a) specification of the functional unit used for LCI calculation of steel products;

b) definition of the system boundaries used for LCI calculation of steel products;

c) evaluation of scrap in LCI calculation of steel products;

d) evaluation of co-products in LCI calculation of steel products;

e) reporting of LCI calculation results of steel products.

The application of LCI results, including life cycle impact assessment (LCIA), is outside the scope of this document.
