Is India’s Shift to Low-Carbon Green Steel a Slow Process?

Key Takeaways
New Delhi, Jan 20 (NationPress) The shift towards low-carbon green steel in India is set to be a slow and long-term journey due to cost and technological barriers that impede swift decarbonisation, as indicated by a recent report released on Tuesday.
Looking ahead to post-2030, the demand for green steel in India is anticipated to surge, driven by stricter ESG compliance requirements, large-scale industries such as automotive, infrastructure, and capital goods seeking to decarbonise their supply chains, along with supportive policy measures.
According to rating agency ICRA, the carbon emission intensity of Indian steelmakers averages around 2.5 tonnes of carbon dioxide for every tonne of steel produced, which is approximately 12 percent higher than the global average for the blast furnace-basic oxygen furnace (BF-BOF) method.
The government's recent implementation of a Green Steel Taxonomy in December 2024 (as part of the National Mission on Green Steel) is a positive development, establishing graded emission thresholds to identify what constitutes “green” steel.
Nevertheless, most primary producers in India currently exceed even the upper limit of this designated green range, highlighting a significant decarbonisation gap that must be addressed, according to the report.
In the near term, the decarbonisation of the domestic steel industry will largely depend on improvements in operational efficiency and increased adoption of renewable energy, which is expected to lead to a 19 percent reduction in emission intensity by 2029-2030, bringing the sector's average down to about 2.0 tCO₂ per tonne by the decade's end, explained Girishkumar Kadam, Senior Vice-President and Group Head at ICRA.
A significant portion of this reduction is projected to stem from the integration of renewable energy and process optimisations, he noted.
The report indicates that Indian steel mills have already announced 9 gigawatts (GW) of captive renewable power capacity, replacing fossil fuel-based electricity in their operations.
Switching to green power alone is expected to decrease emissions by 13 percent for BF-BOF based mills and up to 22 percent for DRI-based steelmaking units.
Other operational strategies, such as increasing scrap usage in furnaces, implementing energy efficiency measures like waste-heat recovery, and enhancing iron ore beneficiation, are expected to further reduce CO₂ emissions per tonne, the report added.
