Steel · DecarbonisationIndia's Blast Furnace Fleet: The Emissions Profile, the Relining Decision Window, and What BF-BOF Operators Can Actually Do Under CCTS and CBAM
India's blast furnace fleet stands as both the country's most productive steelmaking asset and its most daunting industrial decarbonisation challenge. Roughly 65% of India's crude steel output flows from the BF-BOF route. This happens at an average emission intensity of around 2.2 to 2.6 tCO₂e per tonne of crude steel, which sits roughly 54% above the EU CBAM benchmark and more than twice the intensity of scrap-based electric arc furnace production. More than 43 Mtpa of BF capacity is due for relining before 2030. Each relining decision costs between $200 and $300 million, extends the furnace life by 15 to 20 years, and heavily locks the asset into coal-based production through to the 2040s or beyond. This article breaks down exactly what a BF-BOF operator can do within their existing furnace technology to reduce GEI under the CCTS, how those levers interact with massive CBAM cost exposures, and what the pivotal relining decision means for stranded asset risks in the shadow of India's 2070 net-zero commitment.
Key Takeaways
India's operating BF-BOF capacity is approximately 87 Mtpa, with the route accounting for 65% of crude steel production. The sector's average GEI sits at approximately 2.36 tCO₂e per tonne under the CCTS FY 2023-24 baseline. This sits well above the world average of 2.32 tCO₂/t and substantially above China's 1.84 tCO₂/t. The EU CBAM benchmark for steel is approximately 1.55 tCO₂/t for the most efficient EU producers, placing India's BF-BOF fleet at a massive 52% premium before a single certificate is even purchased.
The CCTS iron and steel targets require a GEI reduction from a sector average of 2.36 down to approximately 2.23 tCO₂/t by FY 2026-27. This represents roughly a 5.5% cut over two compliance years. CEEW analysis confirms that most of this reduction lies comfortably in the negative-cost zone of the marginal abatement cost curve. It can be achieved through smart energy efficiency improvements that save more money than they cost, without requiring brand new technology investments or radical production route changes. However, this is only the compliance picture for the first two years. Beyond saving roughly 23 MtCO₂e, deeper cuts will require genuinely capital-intensive interventions.
BF-BOF operators have a well-defined toolkit of within-technology abatement levers that can collectively reduce GEI by 8 to 15% without changing the core production route. The most valuable interventions in the near term, ranked by abatement per rupee of investment, include coke rate reductions through burden optimisation and coal blend improvements. Other vital tools involve using pulverised coal injection to substitute expensive metallurgical coke, installing top pressure recovery turbines for top-gas energy recovery, leveraging coke dry quenching for waste heat capture, and tapping into renewable electricity for Scope 2 intensity reductions under the CCTS gate-to-gate boundaries.
The relining decision is arguably the most consequential capital allocation choice a BF operator will face under CCTS and CBAM frameworks. A major reline costing $200 to $300 million extends the furnace life by 15 to 20 years and locks the asset deep into coal-based production until the early 2040s. By that point, India's CCTS targets will have tightened significantly beyond current levels, and CBAM's embedded emissions will very likely include Scope 2 electricity in addition to current Scope 1 coverage. Global Energy Monitor estimates a staggering $124 to $187 billion in stranded asset risk stemming from India's BF-BOF capacity currently in development alone. For investors and boards, relining a furnace without a parallel decarbonisation roadmap is no longer a simple, straightforward decision.
India is directly responsible for 57% of all global coal-based BOF capacity currently under development. This equates to approximately 73 Mtpa of new BF-BOF capacity planned to begin operations by 2030. This massive expansion is driven by genuine and highly legitimate domestic demand growth. India's steel consumption per capita remains far below developed economy levels, and the sheer scale of infrastructure required by Viksit Bharat 2047 will demand very large volumes of domestically produced steel. The real policy challenge is not to halt this expansion, but to ensure that the new capacity being built today does not repeat the tragic lock-in errors of the last two decades on an even larger scale.
India's BF-BOF fleet: What it produces, what it emits, and who operates it
India successfully produced approximately 149 million tonnes of crude steel in 2024, easily securing its place as the world's second-largest steel producer directly after China. The BF-BOF route, where iron ore is reduced to liquid iron in a coal-fired blast furnace and then refined into steel in a basic oxygen furnace, accounts for approximately 65% of this massive output by production share, carrying a capacity share of around 59%. The remainder mostly comes from electric arc furnaces (approximately 30%) and induction furnaces (approximately 9%), heavily relying on DRI as a key feedstock for the electric route.
The major BF-BOF operators shaping India's landscape are:
Other major contributors like RINL (Rashtriya Ispat Nigam Limited, operating the Vizag Steel plant at 7.3 Mtpa), JSPL (9.6 Mtpa, with a mix of BF and DRI-EAF at Angul), and a growing cohort of smaller integrated BF-BOF units expertly round out the national fleet. The CCTS covers a massive 253 iron and steel units under the notified GEI Target Rules. These range from smaller plants producing 90,000 tonnes per year all the way up to the massive complexes churning out roughly 12 million tonnes.
The emissions intensity gap: Where India's BF-BOF stands against the world
The starting point for any serious decarbonisation analysis is the hard emission intensity benchmark. It is crucial because it determines both the vital CCTS compliance position and the steep CBAM certificate cost for any plant planning to export into the EU. The numbers, frankly, are not flattering for most of India's integrated fleet.
The chart boldly illustrates a deeply structural problem. Even the sector average for India's BF-BOF fleet sits firmly at the high end of the global distribution curve. Worse, the bottom quartile of the fleet, filled with older, smaller blast furnaces operating at lower productivity and higher coke rates, operates at a significantly more intensive rate than this average. When compared against the harsh EU CBAM benchmark of approximately 1.55 tCO₂/t, which actively dictates the certificate cost for EU importers, the average Indian BF-BOF producer carries a painful CBAM liability of approximately 0.81 tCO₂/t straight above the benchmark. If we calculate this using EU ETS pricing at €80 per tCO₂e, it translates to roughly €65 per tonne of steel exported to the EU in strict certificate costs, well before any benchmark deductions are even applied.
This massive gap reflects a nasty combination of legacy factors. Indian blast furnaces have historically operated with much higher coke rates per tonne of hot metal than world best practice dictates. This happens partly because of local iron ore quality. Indian iron ore contains far more fines and gangue, aggressively requiring more energy to properly reduce. It also stems from older, less efficient furnace designs, and the simple historical fact that energy costs in India were once low enough that pushing for peak coke efficiency was never a major commercial priority. The arrival of CCTS and CBAM has violently disrupted this old financial incentive structure. Today, coke efficiency is intrinsically linked to both basic compliance under the domestic carbon market and the raw export cost required to reach the world's largest premium destination market.
The relining decision: Why it matters more than any other capital choice in steel
A massive blast furnace is absolutely not a simple, single asset that can be continuously operated and cheaply upgraded in tiny increments. It features a very definitive operating campaign life, typically spanning 15 to 25 years between major relinings. At the very end of this lifespan, the vital refractory lining, the thick, heat-resistant brick that fiercely protects the steel shell from blistering temperatures exceeding 1,500°C, must be completely ripped out and replaced. A proper relining aggressively requires a full furnace shutdown lasting anywhere from 60 to 120 days. It demands the total demolition and replacement of the furnace interior, and for the larger modern behemoths, it often necessitates the total replacement of ancillary equipment including massive hot stoves, blowers, and complex gas cleaning systems.
The financial cost is staggering. A standard BF relining easily runs $200 to $300 million. For the absolute largest, most modern furnaces, such as the massive 4,000 m³ class actively operated by JSW Steel down at Vijayanagar, these relinings can painfully approach $500 million to $1 billion when necessary associated infrastructure upgrades are factored in. This is absolutely not casual capital that gets written off quietly in a few short years. It represents a massive operating life extension of 15 to 20 years, carrying a brutal, implicit commitment to dirty coal-based ironmaking through to the early 2040s at a minimum.
When a massive blast furnace successfully reaches the end of its campaign and the critical relining decision arrives, the board of an Indian integrated steel producer faces a brutal choice that is simultaneously a massive capital allocation decision, a severe carbon risk decision, and a critical market strategy decision.
Option A: full relining. This demands Rs 2,000 to 2,500+ crore ($300 to $500 million equivalent) for a major integrated BF. It extends the life 15 to 20 years and severely locks in coal-based production until 2040 or 2045. It captures absolutely no carbon benefit from the massive investment, and bakes the increasingly hostile CCTS and CBAM cost trajectories directly into the asset's future baseline economics.
Option B: partial relining or campaign extension. This offers a much lower upfront cost and buys 3 to 7 years of additional operating time. It does not resolve the deep structural decision; it merely defers it, potentially dumping the problem into a much more expensive regulatory environment where less transition support is available.
Option C: transition to DRI-EAF in parallel. This brave move does not eliminate the existing BF's remaining life immediately, but it actively avoids locking in any new coal capacity. The fresh DRI-EAF capacity beautifully serves the exact same steel demand at a vastly lower carbon cost. The aging BF can then be quietly retired at its natural end-of-life. The capital requirement for building equivalent DRI-EAF capacity sits around $200 to $400 million per million tonnes, which is shockingly comparable to the cost of a massive BF reline for many plants. The sharp CCTS and CBAM financial signals, when analyzed together, are rapidly making Option C look materially more attractive on a risk-adjusted basis than anyone thought possible just five years ago.
More than 43 Mtpa of India's currently operating BF capacity is estimated to be due for a massive relining before the close of 2030, according to detailed GEM analysis. For every single furnace sitting in this cohort, the upcoming relining window serves as both the clearest possible opportunity the sector possesses to break the brutal coal-based production cycle, and, if the relining lazily goes ahead without a strong parallel transition plan, the exact moment at which the carbon lock-in is disastrously renewed for another two decades. With India's CCTS targets fully expected to tighten sharply beyond current first-phase levels, and CBAM's aggressive trajectory moving to swallow Scope 2 electricity emissions for steel in later rounds, every single BF relining executed today without a clear decarbonisation roadmap simply builds a vastly more expensive problem for 2040.
What BF-BOF operators can actually do: The abatement toolkit
The absolute key analytical question for any CCTS-obligated BF-BOF plant is not whether the plant must eventually decarbonise; it absolutely must. The real question is what within-technology measures are actively available right now to drastically reduce GEI without entirely replacing the furnace or radically altering the production route. The answer is surprisingly practical. There is a meaningful, albeit firmly bounded, set of smart interventions that can collectively reduce BF-BOF emission intensity by 8 to 15% relative to the baseline. Better yet, the costs for these interventions range from completely negative (meaning measures that quite literally pay for themselves) to moderately capital-intensive but deeply financially justified.
| Abatement Lever | GEI Reduction Potential | Investment Cost | Payback & CCTS Relevance |
|---|---|---|---|
| Coke rate reduction via burden optimisation Improving sinter/pellet ratio; increasing pellet share; better raw material mix. | 2 to 4% GEI reduction | Low to zero | Immediate payback. Saves massive coke costs. Relevant to Scope 1 direct. |
| Pulverised coal injection (PCI) rate increase Injecting fine coal through tuyeres to substitute expensive metallurgical coke. | 2 to 5% GEI reduction per 10 kg/t increase in PCI rate | Low to moderate | 2 to 4 years. Coal is vastly cheaper than coke. Scope 1 direct impact. |
| Top pressure recovery turbines (TRT) Converting blast furnace top-gas pressure to electricity before gas cleaning. | 0.5 to 1.5% GEI reduction (indirect) | Moderate | 4 to 8 years. Generates excellent power revenue. Scope 2 indirect impact. |
| Coke dry quenching (CDQ) Replacing wet coke quenching with nitrogen gas cooling; waste heat to steam/power. | 1 to 2% GEI reduction | Moderate to high | 5 to 10 years. Scope 1 + Scope 2 impact. |
| Hot stove waste heat recovery Recovering preheated air from BF hot stoves for use in adjacent processes. | 0.5 to 1.5% GEI reduction | Low | 2 to 5 years. Scope 1 indirect impact. |
| Sintering efficiency improvement Improving sinter plant energy consumption; reducing sinter return fines. | 1 to 2% GEI reduction | Low to moderate | 3 to 6 years. Scope 1 direct impact. |
| Renewable electricity for grid power substitution Green open access solar or wind PPA to replace grid power consumed in auxiliary systems. | 1 to 4% GEI reduction depending on grid power share | Moderate (PPA or OA fees) | Immediate improvement in CCTS Scope 2 position. Scope 2 direct impact. |
| BOF gas recovery and use Recovering converter off-gas for fuel use in rolling mills or power generation. | 0.5 to 1% GEI reduction | Low | 2 to 4 years. Scope 1 direct impact. Avoids flare emissions entirely. |
When intelligently applied together across a sprawling integrated plant, this robust toolkit can beautifully reduce BF-BOF GEI by 8 to 15% over a practical 3 to 5 year investment programme. Looking at the sector average of 2.36 tCO₂/t, a solid 10% reduction delivers roughly a 0.24 tCO₂/t improvement, dragging the plant down to an impressive 2.12 tCO₂/t. This is more than sufficient to absolutely crush the CCTS first-phase targets for most units, and in many successful cases, it generates a highly valuable surplus of CCCs that can be easily banked or sold on the open market. While it obviously does not completely close the yawning gap to the elite CBAM benchmark of 1.55 tCO₂/t, which strictly requires a massive 35% reduction from the sector average, it undeniably shrinks the painful per-tonne CBAM certificate cost and boldly demonstrates the exact kind of continuous improvement trajectory that skittish investors, cautious lenders, and demanding EU importers increasingly demand.
Deep CEEW analysis confirms that the iron and steel sector's critical CCTS first-phase targets, requiring GEI to steadily fall from 2.36 down to roughly 2.23 tCO₂/t, sit almost entirely in the highly lucrative negative-cost zone of the marginal abatement cost curve. This practically means the required reductions literally pay for themselves in massive saved energy costs. The sector possesses an enormous abatement potential of up to 45 MtCO₂e at a remarkably low or even negative marginal cost, a figure that completely dwarfs the approximately 23 MtCO₂e avoidance heavily demanded by the initial first-phase targets. The reality is blunt. Plants that fail to meet their CCTS targets in FY 2025-26 are, in most cases, simply refusing to implement basic, cost-effective energy efficiency measures that would save them millions even without a carbon market in place. This makes their non-compliance both financially ruinous and operationally baffling.
The absolute outer limits of within-technology abatement
The brilliant abatement toolkit detailed above eventually hits a hard ceiling. Once absolute best practice energy efficiency is finally achieved, featuring elite coke rates hovering around 400 to 420 kg per tonne of hot metal, full waste heat recovery, beautifully optimised burdens, and maximum PCI rates, any further reductions within the old BF-BOF route require science fiction. They demand either technology that simply does not exist yet at a commercial scale, like top gas recycling paired with massive CO₂ capture or aggressive hydrogen injection, or they require the massive injection of biomass-based reducing agents that carry their own severe sustainability questions and brutal supply constraints.
The fundamental constraint is basic chemistry. A blast furnace forcefully reduces iron ore by reacting it fiercely with carbon, primarily coke or other carbon-based reducing agents, to violently strip the oxygen from iron oxide and produce beautiful molten iron. This exact reaction produces massive amounts of CO₂ as a completely irreducible by-product. Even a flawlessly operated, perfectly efficient blast furnace hitting global best practice energy intensity still churns out around 1.5 to 1.8 tCO₂ per tonne of hot metal from this basic chemistry alone. When you stack on the Scope 2 electricity greedily consumed in auxiliary systems and the dirty processing of sinter and coke, the absolute irreducible floor for BF-BOF under standard operations stubbornly sits around 2.0 to 2.2 tCO₂/t of crude steel. This rigid range still sits dangerously above the CBAM benchmark and will invariably carry a heavy certificate cost in the EU export market, no matter how miraculously efficient the plant becomes.
This chemistry ceiling explains exactly why Global Energy Monitor's blunt assessment states plainly that coal-based blast furnaces simply cannot achieve zero or near-zero emissions even with the most expensive retrofits imaginable. It is exactly why the IEA's aggressive roadmap for net-zero steel demands a fundamental, massive shift away from the blast furnace toward DRI-EAF, either gas-based or hydrogen-based, and scrap-EAF as the absolute dominant production routes by 2050. The current BF-BOF toolkit beautifully buys time, extremely valuable, commercially important time, but it utterly fails to provide the true production route that India's bold 2070 net-zero commitment ultimately demands.
India aggressively imports roughly 55 to 60 million tonnes of premium coking coal every single year. Australia heavily supplies around 60% of this, with the remainder flowing in from the United States, Canada, Mozambique, and Russia. The specific coal blend utilized in the massive coke ovens directly determines crucial coke strength. This strength, measured strictly by CSR (Coke Strength after Reaction) and CRI (Coke Reactivity Index), directly dictates the necessary coke rate in the blast furnace and therefore drives the final CO₂ per tonne of iron. Premium hard coking coal ripped from Australia's Bowen Basin consistently produces the highest quality coke and guarantees the lowest coke rates. Cheaper semi-hard and semi-soft coking coals produce significantly lower quality coke, desperately requiring much higher application rates per tonne of hot metal and directly causing higher Scope 1 emissions intensity. While the ongoing West Asia war has not directly strangled coking coal supply routes, which primarily originate safely from the Pacific Basin, the war's severe disruption of vital seaborne shipping insurance and broader logistics indirectly inflates freight costs for all major dry bulk importers. Any further severe geopolitical escalation along vital Indian Ocean trade routes would immediately pile massive supply chain risk onto coking coal procurement, stacking dangerously alongside the direct energy exposure that Indian steel's massive electricity and fuel inputs already desperately carry.
The new capacity question: What India is building and at what carbon cost
The most consequential dimension of India's entire blast furnace story is absolutely not the aging operating fleet. It is the massive 258 Mtpa of fresh steel capacity currently churning through various stages of development, an alarming 69% of which is planned strictly as dirty BF-BOF and a mere 13% as cleaner EAF. India shockingly accounts for 40% of all developing global steelmaking capacity and an astonishing 57% of all global coal-based BOF capacity currently under development. These are definitely not idle numbers easily ignored. They represent massive, concrete investment decisions being finalized today that will violently dictate the emission intensity of India's entire steel sector not just in 2030, but deep into 2045 and far beyond.
India actively boasts 73 Mtpa of new BOF-based capacity trapped in the planning and construction pipeline, heavily set to commence operations by 2030. If this massive capacity is truly built and operated exactly as intended, and if crucial CCTS targets predictably tighten down to 1.8 to 2.0 tCO₂/t by 2035, a highly plausible trajectory given the strict 2035 NDC and India's bold 2070 net-zero commitment, the fresh BF-BOF capacity will instantly face devastating, material compliance shortfalls within a mere 10 to 15 years of commissioning. This creates precisely the terrifying stranded asset risk that GEM aggressively estimates at a staggering $124 to $187 billion. The official National Steel Policy correctly focuses on massive capacity expansion and politely identifies decarbonisation as a parallel objective, but disastrously fails to specify a firm technology requirement that would legally prevent new BF-BOF capacity from being foolishly commissioned. Furthermore, the modern green steel taxonomy, featuring the new 3-star to 5-star framework, successfully creates a clever labelling and procurement signal, but currently lacks the teeth to prohibit fresh coal-based primary capacity from aggressively flooding the market.
The main counterargument to this, and it is an undeniably legitimate one, points out that India's current per-capita steel consumption sitting at a meager 90 kg per year is merely a tiny fraction of China's massive 650 kg or the global developed-economy average hovering around 200 to 250 kg. The sheer volume of steel desperately needed to fuel India's housing booms, sprawling infrastructure projects, massive railways, and explosive industrial growth over the next 20 years is simply not up for debate. The critical policy question is absolutely not whether to stop building. The question is whether the massive new primary steel capacity built to fiercely serve that demand over the next 5 years truly needs to be dirty BF-BOF, or whether the potent combination of strict CCTS, brutal CBAM, rapidly declining DRI-EAF capital costs, and India's soaring green hydrogen ambition can finally shift the massive investment calculus toward vastly lower-carbon primary production routes for at least a highly meaningful chunk of the upcoming capacity.
Frequently Asked Questions
What exactly is the CCTS GEI target for Indian integrated steel plants?
The iron and steel CCTS targets were officially notified in the second crucial tranche of GEI Target Rules, published initially in June 2025 and finalised deeply in October 2025. These rules actively cover a massive 253 individual units. Targets are meticulously set plant-by-plant based entirely on each specific unit's FY 2023-24 baseline intensity. They use a strict benchmarking approach where plants starting with higher baselines are rightfully assigned much more ambitious reduction targets. The sector average baseline sits at roughly 2.36 tCO₂e per tonne of crude steel, with fresh targets requiring a stern reduction down to approximately 2.23 tCO₂e/t by the end of FY 2026-27. For instance, ArcelorMittal Nippon Steel's massive Hazira plant, carrying a baseline of 2.2701, must aggressively reach 2.1696 tCO₂e/t by FY 2026-27. This represents a solid reduction of 4.4% required over two short years. Naturally, plants launching from a much higher baseline face far steeper required reductions in absolute terms.
Can a traditional blast furnace ever realistically meet the EU CBAM benchmark?
Through fierce within-technology optimisation alone, utilizing high PCI rates, razor-thin coke rates, brilliant full waste heat recovery, and perfect burden optimisation, a world-class Indian blast furnace can heroically reach roughly 2.0 to 2.2 tCO₂/t of crude steel. However, this still sits significantly above the brutally tight EU CBAM benchmark of roughly 1.55 tCO₂/t. That benchmark fiercely reflects the performance of the absolute most efficient EU producers, heavily favoring EAF-based plants or hyper-advanced BF-BOF setups leveraging substantial scrap use and massive renewable electricity. Reaching the elite CBAM benchmark from a basic BF-BOF production base absolutely requires a massive production route change, not just basic within-technology tweaks. Therefore, the CBAM certificate cost for any Indian BF-BOF operator exporting to the EU will always sadly reflect some positive gap sitting above the benchmark. While the gap successfully shrinks as BF efficiency aggressively improves, it will never reach absolute zero under the legacy coal-based route.
Why exactly is India's BF-BOF emission intensity noticeably higher than China's?
Several heavy factors contribute to this frustrating reality. Indian iron ore, particularly the massive volumes ripped from Odisha and Jharkhand, naturally contains much higher alumina content and significantly more fines than standard Chinese ore. This heavily requires vastly more energy during crucial sintering and reduction phases. Furthermore, many older Indian blast furnaces operate at noticeably lower coke rates per unit of hot metal than modern Chinese world-class units, driven partly by aging legacy technology trapped in the massive SAIL fleet and partly due to historically lower local fuel cost pressures. Additionally, the standard coal blend actively used in Indian coke ovens has historically included a much higher, cheaper share of imported semi-hard and semi-soft coking coal relative to premium hard coking coal. This produces lower-quality coke that violently drives higher raw consumption rates. Meanwhile, ambitious Chinese steel producers have quietly invested heavily in massive supercritical and ultra-supercritical power generation technology purely for captive power, massively improving efficiency. Finally, India's broader average grid emission factor, sitting high at 0.710 tCO₂/MWh, is considerably higher than China's in many industrial regions, adding massive, unavoidable Scope 2 intensity directly to the comparison.
What exactly does a massive BF relining involve, and how long does it painfully take?
A major blast furnace relining absolutely requires a completely dead shutdown of the entire furnace. During this massive pause, the crucial refractory lining, the thick, heavy heat-resistant brick that fiercely protects the outer steel shell from terrifying molten iron hitting 1,500°C, is entirely demolished and carefully replaced from the deep hearth all the way up. The dead shutdown typically lasts an agonizing 60 to 90 days for a standard reline, and stretches to 90 to 120 days for a massive major reline that heavily includes vital upgrades to giant hot stoves, heavy blowers, and complex other ancillaries. However, brilliant modern techniques like the advanced NSENGI Single Block Method, beautifully used at JSW Steel's massive Dolvi plant back in 2016, can miraculously reduce the most critical, dangerous phase to as little as 4 days of rapid pull-in and pull-out, compared to 15 slow days required for conventional block relining methods. The brutal capital cost for a standard reline of a typical Indian integrated plant sitting in the 2 to 4 Mtpa range hits approximately Rs 1,500 to 2,500 crore ($180 to $300 million), with the absolute largest units easily exceeding this massive range.
Does aggressively improving BF efficiency meaningfully reduce CBAM costs as well as standard CCTS compliance costs?
Yes, absolutely. In fact, the lucrative CBAM benefit is currently vastly larger than the domestic CCTS benefit per tonne of CO₂e actively reduced. This is simply because harsh CBAM certificate prices, hovering around €80/tCO₂e at current EU ETS pricing and equating roughly to Rs 7,200/tCO₂e, are massively higher than expected early CCTS prices, which float around a mere Rs 300 to 900/tCO₂e based heavily on early market estimates. Therefore, every single tonne of CO₂e by which a massive steel plant successfully reduces its BF-BOF emission intensity below its official baseline beautifully delivers approximately Rs 7,200 in totally avoided CBAM certificate cost for lucrative exports heading to the EU, against a mere Rs 300 to 900 in domestic CCTS market value. This massive, glaring asymmetry perfectly means that for major steel exporters, the CBAM business case for aggressive BF efficiency investment is massively stronger than the CCTS case alone, beautifully reinforcing the exact same smart investment decision from two very different directions simultaneously.
