India’s steel expansion risks locking in 25% emissions cuts while doubling capacity—structural shift needed to avoid carbon lock-in and global inequity

Traditional Indian metallurgical practices, such as the *loha* (iron) smelting techniques of the Adivasi communities in Jharkhand and Chhattisgarh, achieved low-carbon iron production using renewable charcoal and localized ore processing. These methods were systematically marginalized during British colonial rule, which imposed energy-intensive blast furnaces to serve imperial supply chains. Modern 'green steel' initiatives could revive these techniques by integrating indigenous knowledge with modern engineering, yet corporate and state actors continue to prioritize high-throughput, high-emission models. The erasure of these practices reflects a broader colonial epistemological violence that devalues non-Western scientific traditions.

India’s steel expansion mirrors historical patterns of industrialization, where latecomer economies adopt high-carbon technologies to 'catch up,' only to face stranded assets and debt crises later. The UK’s 19th-century steel boom led to decades of pollution and worker exploitation, while Japan’s post-war steel industry triggered severe environmental degradation before regulations curbed emissions. India’s current plan risks repeating this trajectory, with 25% emissions cuts by 2030 still allowing a 100% capacity increase—echoing China’s 2000s steel glut, which now faces overcapacity and trade wars. The lack of historical reflection in policy debates ensures these patterns will recur.

In Africa, countries like South Africa and Nigeria are pursuing steel expansions with similar 'green transition' rhetoric, yet face the same structural constraints: reliance on foreign capital, lack of green tech transfer, and pressure to meet global demand. Latin American nations like Brazil have leveraged hydroelectric power for low-carbon steel, but these models are sidelined in favor of fossil-fueled expansion. In East Asia, South Korea’s POSCO steel plant in India exemplifies how foreign corporations export high-emission models while claiming 'sustainability.' These cross-cultural parallels reveal a global pattern where 'green steel' is often a misnomer, masking continued carbon lock-in under the guise of development.

Scientific consensus confirms that steel production accounts for 7-9% of global CO2 emissions, with blast furnace-basic oxygen furnace (BF-BOF) routes emitting ~2.3 tons of CO2 per ton of steel. Emerging technologies like hydrogen-based direct reduction (H-DRI) and carbon capture and storage (CCS) can reduce emissions by 50-90%, but require massive infrastructure investments and renewable energy inputs. India’s 25% reduction target is achievable with incremental efficiency improvements, but doubling capacity without scaling green steel risks locking in 20-30 years of emissions. The IPCC’s AR6 emphasizes that without immediate deployment of breakthrough technologies, steel emissions will continue to rise through 2050.

Steel is not just a commodity but a cultural symbol—from the sacred *damascus* blades of the Middle East to the iron pillars of ancient India, which resisted rust for 1,600 years due to low-carbon smelting techniques. Indigenous artists in Odisha and Jharkhand use scrap metal in folk art and rituals, transforming industrial waste into cultural heritage. Yet the modern steel industry treats these materials as mere inputs for profit, severing the spiritual and artistic connections to metal. A systemic shift would require reimagining steel as a medium of cultural resilience, not just economic growth.

If India proceeds with its current plan, steel emissions could peak at 300-400 MtCO2 by 2035, delaying global net-zero targets by a decade. Scenario modelling by the IEA and TERI shows that without green steel mandates, India’s steel sector will consume 25% of the country’s remaining carbon budget by 2050. Alternative pathways—such as scaling hydrogen DRI with renewable energy or adopting circular economy models—could reduce emissions by 70% by 2040 but require $150-200 billion in investments. The risk of carbon lock-in is exacerbated by global steel demand projections, which anticipate a 30% increase by 2050, primarily driven by Global North consumption patterns.

Adivasi and Dalit communities in steel-producing regions like Jharkhand, Odisha, and Chhattisgarh face displacement, water contamination, and respiratory diseases from coal-based steel plants, yet their testimonies are excluded from policy debates. Informal steel workers—who comprise 30% of India’s steel workforce—lack labor protections and are excluded from 'green transition' plans that focus on formal sector decarbonization. Women in mining and smelting regions bear disproportionate health burdens, yet their knowledge of local ecosystems and low-carbon alternatives is ignored. The framing of 'India’s steel expansion' erases these voices, treating marginalized communities as collateral damage rather than stakeholders in systemic change.
