Steel - Rebar

Emission intensity of steel - Rebar. A steel reinforcing bar is rolled on a hot rolling mill. It can be found on the market for direct use or is further processed into finished products by the manufacturers. This product is used to strengthen concrete in highway and building construction also as primary product for the wire rod process. System expansion was used on the steel e.g. for blast furnace slag and other co-products. The influence of system expansion to the GWP for steel products is 3 to 7% lower GWP.

This gives a net life cycle inc Mod D of 1.2 kg CO2e per kg. The source does not clarify if the kgCO2e value is calculated using either IPCC Fourth Assessment Report (AR4) or IPCC Fifth Assessment Report (AR5) methodologies.
