Recent research has shown that the global steel industry’s greenhouse gas (GHG) footprint was around 4.43 gigatonnes of C02equivalent (GtC02e) in 2023, which was 8.2% of total global GHG emissions of around 53.8 GtC02e in that year. The steel industry’s share in total global C02 emissions, excluding other GHGs, was higher at 10.7%. In 2025, global steel industry emissions actually fell marginally by 0.4% y-o-y. But this has been due to decrease in production because of weak economic sentiments and slump in demand rather than through low-carbon technology deployment.
