BRSR for Steel — BF-BOF vs EAF, CBAM Exposure, CCTS, Coking Coal + Scrap Strategy

Why this industry matters for BRSR

The Indian steel sector contributes ~12% of national industrial CO₂ emissions + is the second-largest emitting industrial sector after cement. Within the SEBI BRSR Top 1,000 universe:

• Integrated steel producers (BF-BOF route): Tata Steel, JSW Steel, SAIL (Bhilai, Bokaro, Rourkela, IISCO, Burnpur, Salem, Visvesvaraya), AM/NS India, Vedanta steel (ESL Steel)
• EAF / induction furnace based + secondary producers: Jindal Steel + Power (JSPL), Welspun Specialty Solutions, Hi-Tech Pipes, Goodluck India, several regional players
• Stainless steel: Jindal Stainless, Mukand
• Speciality steels: Tata Steel Long Products, Ratnamani Metals + Tubes

The sector is unique in BRSR practice because it sits at the intersection of three regulatory regimes that drive parallel decarbonisation pressure:

1. SEBI BRSR + BRSR Core (domestic disclosure mandate)
2. CCTS (domestic compliance market with sector-specific intensity targets)
3. EU CBAM (export market access cost from 2026 onwards)

No other Indian industrial sector currently faces this triple pressure simultaneously.

Material BRSR Core attributes

For an integrated steel plant, all 9 BRSR Core attributes are material; the 5 attributes dominating the assurance scope are:

Core attribute	Why material for steel
GHG Emission Intensity per Revenue	Dominant emission contributor; per-tonne-of-crude-steel intensity is the operational KPI (Scope 1 dominates for BF-BOF; Scope 2 dominates for EAF)
Energy Footprint Disclosure	Coking coal + thermal coal + natural gas + electricity all aggregated in GJ; coke oven + BF + BOF gas recovery affects net energy
Water Withdrawal Intensity	Cooling water for continuous casting + rolling mills; 25-50 m³ per tonne of crude steel; closed-loop recycling target is critical
Embracing Circularity — Waste	BF slag + BOF slag + dust + coke-oven by-products; scrap as recycled input
Safety Metrics — LTIFR + Fatalities	Molten metal + cast-house + gas-handling + hot rolling all high-hazard; contractor LTIFR 2-4× employee LTIFR

For EAF-only / mini-mill operations, the Scope 1 share drops + Scope 2 (electricity for the furnace + rolling) dominates; the strategic narrative shifts to electricity-source decarbonisation + scrap supply.

BF-BOF vs EAF — the two dominant routes

Blast Furnace - Basic Oxygen Furnace (BF-BOF) — integrated steel

The traditional integrated steelmaking route:

1. Coke oven — bituminous coal → metallurgical coke + by-product gas + tar / benzene
2. Sinter plant + pellet plant — iron ore fines → sinter / pellets feedable to BF
3. Blast furnace — iron ore (sinter / pellets / lump ore) + coke + limestone → hot metal (pig iron) + BF slag + BF gas
4. Basic Oxygen Furnace — hot metal + scrap + lime → liquid steel + BOF slag + BOF gas
5. Continuous casting + hot rolling + finishing

Typical Scope 1 intensity: 2.0 - 2.3 tCO₂e per tonne of crude steel. The Scope 1 split:

• Coke production + BF iron-making: ~70% of mill Scope 1
• Sinter / pellet production: ~10-15%
• BOF + downstream rolling: ~10%
• Lime + dolomite calcination (small process emissions): ~3-5%
• Auxiliary boilers + utilities: balance

The BF-BOF route is dominant in India (~60-65% of total crude steel production); SAIL, Tata Steel, JSW Steel Vijayanagar + Dolvi, AM/NS India + Vedanta ESL operate primarily BF-BOF.

Electric Arc Furnace (EAF) — secondary / mini-mill

Uses electricity to melt scrap + DRI (sponge iron) in an electric arc furnace:

1. Scrap / DRI feed + flux additions
2. Electric arc furnace — electrical energy melts the charge; some carbon injection for chemistry; furnace gases captured
3. Ladle metallurgy + continuous casting + rolling

Typical Scope 1 intensity: 0.4 - 0.7 tCO₂e per tonne (depending on DRI vs scrap mix + DRI source). Scope 2 intensity depends heavily on the electricity source — grid electricity using CEA factors yields significant Scope 2; captive renewable PPA dramatically reduces it.

EAF accounts for ~35-40% of Indian crude steel production; concentrated in induction-furnace + EAF mini-mills + specialty producers like Jindal Stainless.

DRI (sponge iron) — coal-based vs gas-based

India is the world’s largest DRI producer (~40 million tonnes / year), almost entirely coal-based:

• Coal-based DRI (rotary kiln) — coal + iron ore → DRI + waste gas. Higher Scope 1 (~1.4-1.7 tCO₂e per tonne DRI) than gas-based.
• Gas-based DRI (shaft furnace, MIDREX / HYL) — natural gas + iron ore → DRI. Lower Scope 1 (~0.7-0.9 tCO₂e per tonne DRI). Rare in India due to gas availability + pricing.
• Future: green hydrogen DRI — H₂ + iron ore → DRI. Near-zero Scope 1 if H₂ is renewable-powered electrolysis. Pilot stage globally + early R&D in India.

EU CBAM definitive regime — the strategic risk

CBAM is the most concrete near-term decarbonisation pressure on Indian steel exporters.

Mechanism

EU importers of CBAM-scoped products (steel + cement + aluminium + fertilisers + hydrogen + electricity) must:

• Transitional period (1 Oct 2023 - 31 Dec 2025): file quarterly CBAM reports declaring embedded emissions; no financial obligation
• Definitive regime (from 1 Jan 2026): purchase CBAM certificates equivalent to embedded emissions × (EU ETS weekly average price); deduction for verified carbon cost paid in country of origin

Indian steel exposure

Major Indian steel exporters to EU (per latest trade flows):

• Tata Steel (UK + Netherlands operations are EU; Indian operations export to EU)
• JSW Steel (significant EU exports of hot-rolled coil + flat products)
• SAIL (limited EU exports)
• AM/NS India (parent ArcelorMittal has captive EU offtake)
• Jindal Stainless (EU exports of stainless flat products)
• Welspun Specialty Solutions (EU exports of specialty steel)

CBAM certificate cost per tonne of Indian BF-BOF crude steel imported into EU (illustrative, at EU ETS ~EUR 75/tCO₂e):

• Embedded emissions ~2.0 tCO₂e per tonne crude steel
• CBAM certificate cost = 2.0 × EUR 75 = EUR 150 per tonne crude steel (USD ~160; INR ~13,500)

This is meaningful relative to steel price (~EUR 700-900 per tonne flat product); ~17-20% effective import cost increase for high-embedded-emissions Indian steel.

CBAM-driven decarbonisation

Indian steel entities respond via:

• Internal carbon pricing anchored to EU ETS forward curves (typically ₹6,000-8,000 / tCO₂e for capex evaluation)
• Decarbonisation roadmap with intermediate milestones — BF efficiency, scrap/DRI substitution, captive renewable PPA for EAF / rolling mills, future green H₂ DRI
• SBTi target setting (Tata Steel + JSW Steel have SBTi-validated targets)
• Lower-carbon product line — JSW Steel’s “Neosteel” + Tata Steel’s “Steel for Green” lines target sustainability-premium pricing

For the CBAM mechanism, embedded-emissions methodology + sector-specific implementing acts, see the CBAM glossary entry.

CCTS interaction with CBAM

Currently no formal EU recognition that CCTS payments (CCC purchases or environmental compensation) deduct from CBAM certificate cost. This means Indian steel exporters face CCTS compliance cost + CBAM cost in parallel, without offset. Ongoing India-EU trade discussions may bring future mutual recognition; not in force as of 2026.

CCTS iron + steel compliance

Iron + steel is a CCTS 2023 notified obligated sector under the same framework as thermal power. Per Ministry of Power’s CCTS notification:

• Target metric: tCO₂e per tonne of crude steel at the plant level
• Cycle length: 3 years
• Sector-specific intensity reduction trajectory escalating each cycle
• Over-achievement → CCCs tradable on IEX / PXIL
• Under-achievement → CCC purchase + retirement OR environmental compensation

Iron + steel was also a PAT obligated sector since 2012 (PAT cycle history covers 8+ cycles); the CCTS targets build on the PAT baseline + extend the trajectory. For the PAT history + transition mechanics, see the PAT Scheme glossary entry.

Water + waste + circularity profile

Water

Integrated steel plants use 25-50 m³ of water per tonne of crude steel — for blast-furnace cooling, continuous-caster cooling, rolling-mill descaling, coke quenching, and auxiliary cooling. Modern Indian integrated mills target closed-loop water recycling rates of 90%+ (Tata Steel Jamshedpur publishes ~95%; JSW Vijayanagar similar).

The Water Withdrawal Intensity Core attribute captures all withdrawal categories. The closed-loop recycling rate is disclosed as a Leadership Indicator narrative under Principle 6.

BF + BOF slag

• BF slag — ~250-350 kg per tonne of hot metal. Granulated BF slag is used in cement (PSC — Portland Slag Cement) + as supplementary cementitious material in concrete. Indian utilisation rate is high (~85-95%); the Embracing Circularity attribute captures slag as a recycled output.
• BOF slag — ~120-160 kg per tonne of crude steel. Used in road aggregate, soil conditioner, recycle to sinter plant. Lower utilisation rate (~60-75%) due to higher free-lime content.

Coke-oven by-products

Coke-oven gas (COG) + tar + benzene + ammonium sulphate are recovered as commercial products from coke ovens — important for both energy efficiency + circularity. COG is used as fuel within the plant (reducing external natural gas / fuel oil purchase); tar + benzene are sold as chemical feedstocks.

Hazardous waste

• Spent acid (HCl) from pickling lines — neutralised + reused or treated
• Mill scale — recycled to sinter plant
• Spent lubricating oil + coolant emulsions — sent to authorised recyclers
• Refractory waste from furnace relining — Form 10 manifest to authorised TSDF

Material disclosures by NGRBC Principle

Principle 1 — Ethics, Transparency + Accountability

• Compliance with mining lease conditions (for captive iron ore + coking coal mines)
• Forest + environmental clearance compliance for greenfield + brownfield expansions
• Anti-competitive conduct (concentration in long-product segment)

Principle 2 — Sustainable Products + Services

• Lifecycle GHG footprint disclosure per worldsteel methodology
• Lower-carbon product lines + EPDs (Environmental Product Declarations)
• Take-back of end-of-life steel (intersects with EPR for specific product categories)

Principle 3 — Employees + Workers Wellbeing

• Safety Metrics — LTIFR + Fatalities — molten metal + cast-house + gas-handling
• Contractor worker safety + safe-systems-of-work documentation
• Gender Diversity — historically very low female representation in steel operations; improving via targeted recruitment

Principle 4 — Stakeholder Engagement

• Mining-affected community engagement (for captive iron ore + coking coal mines)
• Land + R&R compliance per state R&R policies + the LARR Act 2013
• Tribal consultation under Forest Rights Act 2006 (where applicable)

Principle 5 — Human Rights

• Migrant + tribal worker welfare at mine + plant sites
• Supply chain due diligence (coking coal sourcing — international suppliers’ labour practices)

Principle 6 — Environment

• All 4 environmental Core attributes (GHG, water, energy, waste) are material
• SOx + NOx + PM emissions per MoEFCC standards (especially around coke ovens + sinter plants)
• Mine reclamation + biodiversity (for captive mining operations)

Principle 7 — Public Policy

• Industry-association advocacy (Indian Steel Association, Steel Authority of India in policy fora)
• Position on coal phase-out + green steel premium pricing + CBAM trade discussions

Principle 8 — Inclusive Growth

• MSME supplier development + procurement %
• Job creation in smaller towns (steel plants are often the major employer in their location)
• CSR programmes around plant locations (Tata Steel Jamshedpur is the canonical example)

Principle 9 — Customer Value

• Product quality + after-sales service
• Customer complaint redressal
• Sustainability-linked product narratives (Tata “Steel for Green”, JSW “Neosteel”)

Audit findings specific to steel sector

1. worldsteel methodology not properly applied. The methodology has specific treatment for BF gas / BOF gas / COG recovery (these are netted as fuel substitution, reducing reported Scope 1). Entities that don’t follow worldsteel often double-count fuel input.
2. Hot metal vs crude steel boundary. Some metrics are per-tonne-of-hot-metal (BF output); others per-tonne-of-crude-steel (BOF output). Mixing the two in narrative reporting causes restatement.
3. CBAM embedded-emissions calculation methodology. EU CBAM uses a specific methodology for embedded emissions calculation per Implementing Regulation (EU) 2023/1773. Indian exporter’s BRSR Scope 1 + 2 figures must be converted to CBAM methodology — they’re not identical.
4. Scrap as recycled input — supplier declaration gap. Recycled-input claim for scrap purchases requires the scrap supplier’s documentation that the scrap is genuinely post-consumer or post-industrial recycled material. Pre-consumer mill scrap returned in-house is not “recycled input” — it’s internal recycling.
5. CCTS target overlap with PAT baseline. PAT-VIII iron + steel cycle and CCTS targets coexist for the transition period. Disclosure should clearly state the prevailing regime for the reporting cycle.
6. Coking coal Scope 3 under-reported. Coking coal procurement (largely imported) is a dominant Scope 3 Cat 1; some entities under-report by using only the supplier’s declared upstream emissions rather than the full life-cycle calculation per GHG Protocol Scope 3 Standard.
7. Mine emissions boundary. For entities with captive iron ore / coal mining, the mine operations’ Scope 1 is part of the entity’s consolidated Scope 1 (not Scope 3). Mine equipment fuel + blasting + ventilation are all in scope.
8. BF slag utilisation timing. Slag dispatched to cement company doesn’t equal slag utilised in cement. The utilisation step (when the cement plant actually consumes the slag) is the legitimate count; some entities count dispatch.

Sustainability-linked finance + green steel

Several Indian steel entities have raised sustainability-linked loans (SLLs) + green bonds tied to specific decarbonisation KPIs:

• Tata Steel Group — SLL with KPIs on Scope 1 intensity + renewable electricity %
• JSW Steel — SLL with KPIs on per-tonne emission intensity
• Vedanta Steel (ESL) — SLL aligned with SBTi commitment

These instruments create direct financial consequences for BRSR-disclosed KPI performance (interest rate step-ups for missing targets, step-downs for exceeding). The BRSR P6 + P7 narrative typically discloses sustainability-linked financing activity.
