Currently 6-9% of all global carbon emission are from steelmaking. Coal meets around 75% of the energy demand in the steel sector. Active and significant reduction of carbon emissions is needed to ensure the net zero goal is met by 2050.
Three major changes to reduce carbon emissions in the
steelmaking process:
Renewable Energy: Using renewable energy to power the process.
DRI or scrap: Replacing BF and coke with hydrogen as the reductant, as it releases only water.
Electric Arc Furnace (EAF): Harnessing DRI and scrap with EAF to produce green steel.

Scope 1
emissions of the Greenhouse Gas Protocol looks at the direct emissions from an
organisation’s sites and assets, which is the source of the largest proportion
of CO2 emissions.
