Global steel emissions intensity 2007-2022

The global average emissions intensity of steel production in 2022 was 1.91 metric tons of carbon dioxide (tCO₂) per metric ton of crude steel cast. The CO₂ emissions intensity of steel production has increased by roughly six percent since 2007. The most carbon intensive steel production process is blast furnace-basic oxygen furnace (BF-BOF).

Average carbon dioxide (CO₂) emissions intensity of steel production worldwide from 2007 to 2022 (in metric tons of CO₂ per metric ton of crude steel cast)

Supplementary notes

CO₂ emissions intensity includes all scopes (1, 2, and some scope 3). The two intensities represent production weighted averages between blast furnace-basic oxygen furnace (BF-BOF), scrap-based electric arc furnace (EAF) and direct reduced iron (DRI)-based EAF steel production.

BF-BOF = Blast Furnace-Basic Oxygen Furnace
Scrap-EAF = Electric Arc Furnace Process
DRI-EAF = Direct Reduced Iron-based electric arc furnace process
