CCTS Impact on Iron & Steel: Compliance Costs & Decarbonisation Pathways

Iron & steel is the largest obligated industrial cohort under CCTS with 253 facilities facing ₹3,860–3,960 crore in annual compliance exposure. Driven by coal-dominated production (70–75% of output), the sector faces a cumulative deficit of ~9.9 million tonnes by FY 2029-30—establishing it as the primary demand anchor for carbon credits. This analysis quantifies exposure, details decarbonisation pathways (EAF, hydrogen DRI, CCUS), and outlines the USD 283 billion capex required for sector transformation.

CCTS Sectoral Snapshot: Iron & Steel

Metric	Value
Obligated Facilities	253 (largest cohort: integrated mills, DRI-EAF, secondary steel)
Weighted Average Reduction (WAR)	1.85% annually
Baseline Emissions Intensity	~2.36 tCO₂/t crude steel
Compliance Position	NET SHORT (deficit sector)
Annual Compliance Exposure	₹3,860–3,960 crore across 253 facilities
Cumulative Deficit (FY29-30)	~9.9 million tonnes CCCs

Why Iron & Steel Faces Acute Compliance Exposure

The iron & steel sector is uniquely vulnerable to CCTS compliance costs due to structural reliance on coal-based production processes:

Coal-Dominated Production (70–75% of Output)

Indian crude steel production is dominated by three route types:

• Integrated blast furnace-basic oxygen furnace (BF-BOF): ~55% of output, using coal as fuel and reducing agent. Emissions: 2.1–2.3 tCO₂/t crude steel
• Direct Reduced Iron (DRI) via coal: ~15% of output, coal-based DRI reduced in electric arc furnaces. Emissions: 1.8–2.0 tCO₂/t
• Scrap-based EAF: ~30% of output, electric arc furnaces using recycled scrap. Emissions: 0.5–0.7 tCO₂/t (electricity dependent)

Blended across routes, sector emissions intensity averages ~2.36 tCO₂/t, significantly above equivalent best-practice benchmarks in low-carbon economies. Without major process shifts or renewable power scaling, most facilities will exceed GEI benchmarks, requiring sustained credit purchases.

Compliance Deficit Trajectory

The sector's cumulative deficit grows as benchmarks tighten faster than operational improvements can deliver:

Period	CCC Deficit (lakh t)	Trajectory
FY 2025-26	4.87 (early-phase, moderate)	Moderate deficit
FY 2026-27	18.0 (sharp increase)	Benchmark tightening acceleration
FY 2029-30	99.0 (cumulative)	9.9 million tonne cumulative demand for CCCs

Steel as the Primary Demand Anchor for CCTS Pricing

While cement is the market's largest supplier, steel is the primary demand anchor. With a cumulative deficit of 9.9 million tonnes by FY 2029-30, the steel sector will absorb the majority of cement's credit supply, establishing steel's price-setting behavior as critical to CCTS equilibrium:

• Credit demand concentration: 253 obligated facilities with persistent deficits means sustained buyer pressure throughout transition cycle
• Price elasticity: Steel's capital intensity means producers will tolerate higher credit prices to maintain competitiveness, creating price floors that exceed purely marginal cost
• Market power: Consolidated buyer base (major JSW, Tata, ArcelorMittal, others) means negotiating power with cement suppliers; long-term contracts at fixed pricing likely to emerge

Decarbonisation Pathways: Technology Options & Timelines

The sector has multiple decarbonisation levers available across different timescales and capex profiles:

1. Energy Efficiency (Near-Term: FY 2025-27)

Potential: 5–7% emissions intensity reduction. Mechanisms:

• Furnace insulation and air preheating improvements
• Motor and drive efficiency upgrades
• Waste heat recovery and steam efficiency
• Capex: ₹50–100 cr per 1 Mt capacity, ROI 3–5 years via fuel savings

2. Scrap-Based EAF Expansion (Medium-Term: FY 2027-30)

Potential: ~70% emissions reduction (0.5–0.7 tCO₂/t vs. 2.1–2.3 from BF-BOF). Requirements:

• Abundant recycled scrap supply (India's scrap-to-crude steel ratio is low, ~20%)
• Renewable electricity for EAF (carbon intensity of power directly impacts EAF emissions)
• Capex: ₹250–400 cr per 1 Mt EAF capacity
• Timeline: 3–5 years from project conception to production

3. Hydrogen-Based Direct Reduced Iron (DRI) (Long-Term: 2030+)

Potential: Near-zero carbon production. Status: Pre-commercial in India; in pilot/early commercial phase globally (Salzgitter, SSAB). Requirements:

• Green hydrogen production infrastructure (electrolysers, renewable power)
• Cost parity with coal-based DRI (currently hydrogen DRI is 2–3x more expensive)
• Capex: ₹500–800 cr per 1 Mt hydrogen DRI capacity
• Timeline: 2030–2035 for commercial deployment at scale in India

4. Carbon Capture, Utilization & Storage (CCUS) (Emerging)

Potential: 30–50% process emissions reduction via carbon capture from blast furnace off-gas. Status: Pilot stage globally. Capex: ₹100–200 cr per capture unit; not yet economic at scale in India.

Sector-Wide Capex Requirements for Decarbonisation

The Council on Energy, Environment and Water (CEEW) estimates USD 283 billion total capex required for India's steel sector transformation through 2050, with the majority concentrated in FY 2025-2035 CCTS compliance cycles. Key allocation:

Technology / Pathway	Capex (USD Billion)	Deployment Timeline
Energy Efficiency	USD 25–35 B	FY 2025-27 (near-term)
EAF Capacity Expansion	USD 80–120 B	FY 2027-33 (medium-term)
Hydrogen DRI Infrastructure	USD 120–140 B	2030–2050 (long-term)
CCUS & Emerging Tech	USD 20–30 B	Pilot through commercialization

GEI Benchmark Notification Status & Planning Uncertainty

As of early 2026, facility-specific GEI benchmarks for iron & steel remain PENDING (notification expected early 2026). This creates ongoing planning uncertainty:

• Unknown baseline: Without notified benchmarks, facilities cannot precisely quantify compliance deficits or credit purchase requirements
• Multiple scenarios: Most producers are developing 3–5 scenario capex roadmaps to accommodate tighter or looser-than-expected benchmarks
• First-mover advantage: Facilities that deploy efficiency capex and secure renewable PPAs early will be better positioned regardless of final benchmark stringency

Financial Impact: Credit Costs & Margins

Annual compliance exposure by facility type (assuming 1 Mt capacity):

Facility Type	GEI (tCO₂/t)	Annual CCC Liability (₹)	% of Profit Margin
Integrated BF-BOF	2.1–2.3	₹315–345 cr	20–35%
Coal-Based DRI-EAF	1.8–2.0	₹270–300 cr	15–30%
Scrap-Based EAF	0.5–0.7 (grid-dependent)	₹75–105 cr	5–15%

For integrated mills, CCTS compliance costs can represent 20–35% of profit margin, materially impacting competitiveness. This underscores the urgency of capex deployment and the strategic importance of renewable power procurement.

Key Takeaways

• Iron & steel is the largest obligated cohort (253 facilities) and primary credit demand anchor, facing ₹3,860–3,960 crore annual compliance costs and 9.9 million tonne cumulative deficit through FY 2029-30
• Coal dominance (70–75% of production) makes sector structurally exposed; baseline emissions intensity (~2.36 tCO₂/t) significantly exceeds low-carbon peer benchmarks
• 1.85% annual WAR tightening compounds exposure; deficit grows sharply from 4.87L tonnes (FY25-26) to 99L tonnes cumulative by FY29-30
• Four decarbonisation levers available: energy efficiency (5–7%), EAF expansion (70% reduction), hydrogen DRI (near-zero), CCUS (emerging). USD 283 billion capex required; majority FY 2025-2035
• GEI benchmarks PENDING (expected early 2026); facility-level planning uncertainty until notification. Integrated mills face highest margin impact (20–35% of profit), creating strongest incentive for early capex deployment
