Aluminium · Secondary & Recycling · CBAM & CCTSIndia’s Secondary Aluminium Sector: The CBAM Benchmark Gap Between 0.139 and 1.464 tCO₂/t Is the Largest Carbon Cost Differential in Any CBAM Product — and India’s Recyclers Already Qualify
The leaked EU CBAM provisional benchmark document published in December 2025 contains the single most commercially transformative number for India’s aluminium industry: the secondary aluminium CBAM benchmark is 0.139 tCO₂e per tonne, compared to 1.464 tCO₂e per tonne for primary aluminium. The secondary route applies when more than 50% of the aluminium is sourced from scrap. India’s secondary aluminium industry produces at approximately 0.3-1.3 tCO₂/t depending on the energy source used for remelting — well below both the secondary CBAM benchmark and the primary benchmark. At EU ETS prices of approximately €60/tCO₂e, an Indian secondary aluminium exporter to the EU pays approximately €8/t in CBAM certificates, while an Indian primary coal-CPP producer facing the default rate would pay approximately €800/t. This €792/t CBAM advantage for secondary over primary coal-CPP aluminium is the largest carbon cost differential in any CBAM-covered product category — larger than the gap in steel, fertilisers, or cement. India’s secondary aluminium sector — producing approximately 1.5 million tonnes per year, growing at 6-8% annually — is structurally positioned to capture this CBAM advantage if it can secure scrap supply, navigate the EU’s 2025 Waste Management Rule restricting scrap exports from non-OECD countries, and scale its production base ahead of the first annual CBAM declaration in May 2027. This article maps the full secondary aluminium economics: production volumes, scrap supply dynamics and constraints, the CCTS targets gazette-notified on January 16, 2026, the CBAM calculation, and the investment case for scaling India’s recycled aluminium sector through 2030.
The EU CBAM benchmark for secondary aluminium is 0.139 tCO₂e per tonne — compared to 1.464 tCO₂e per tonne for primary aluminium. The secondary route applies when more than 50% of the aluminium input is sourced from scrap. This benchmark gap of 1.325 tCO₂e per tonne is the most commercially significant number in India’s aluminium CBAM exposure picture. At EU ETS prices of approximately €60/tCO₂e: primary aluminium CBAM certificate cost = approximately €88/t; secondary aluminium CBAM certificate cost = approximately €8/t. The difference is €80/t — approximately Rs 7,200/t at current exchange rates. For India’s coal-CPP primary aluminium producers, which carry verified GEI of approximately 13-16 tCO₂/t (versus the 1.464 primary benchmark), the CBAM exposure is even larger — at the default rate this could be €800/t or more. Secondary aluminium producers face essentially zero CBAM exposure for EU exports, since their typical GEI of 0.3-1.3 tCO₂/t sits below the 0.139 secondary benchmark when using efficient gas or RE-based remelting.
The energy economics of secondary aluminium are fundamentally different from primary. Secondary aluminium production — remelting scrap in rotary, reverberatory, or induction furnaces — requires approximately 5% of the energy used in primary aluminium production from bauxite through electrolysis. Primary aluminium requires approximately 13-15 GWh per tonne of metal (of which 13 GWh is for the electrolysis cell alone). Secondary aluminium requires approximately 0.5-1.0 GWh per tonne for the remelting process, and no electrolysis. The CO₂ impact of this energy difference is the foundation of the secondary sector’s regulatory advantage: primary coal-CPP aluminium at 14 tCO₂/t; secondary aluminium with gas remelting at 0.5-0.8 tCO₂/t; secondary aluminium with RE-based remelting at 0.2-0.4 tCO₂/t. India’s MRAI has cited 0.3 tCO₂/t as the typical CO₂ imprint of secondary aluminium production. This figure qualifies Indian secondary producers for the CBAM secondary benchmark, for CCTS CCC surplus generation, and for any green aluminium procurement premium that EU buyers apply.
CCTS targets for secondary aluminium were gazette-notified on January 16, 2026 as part of the final GHG Emission Intensity Target Rules, along with refinery, petrochemicals, and textiles. Hindalco Industries’ Taloja aluminium plant (Maharashtra), which is India’s largest secondary aluminium facility, carries a baseline GEI of 1.3386 tCO₂ per tonne from its FY2023-24 data, with targets of 1.2563 tCO₂/t by FY2026-27. At 1.3386 tCO₂/t baseline against a Phase 1 target of approximately 1.32 tCO₂/t, Hindalco Taloja’s CCTS compliance burden is modest — the facility is already performing well below the primary aluminium average of 13-16 tCO₂/t. The CCTS targets for secondary aluminium are therefore not a compliance threat but a CCC opportunity: any outperformance below the notified target generates surplus CCCs that can be sold on the exchange. A secondary aluminium facility that invests in gas-to-RE remelting energy transition could generate 0.1-0.5 tCO₂/t of CCC surplus — worth Rs 80-400 per tonne of secondary aluminium at Rs 800/CCC — in addition to the CBAM certificate cost saving on EU exports.
The scrap supply constraint is the primary barrier to scaling India’s secondary aluminium sector. India’s domestic aluminium scrap pool is growing — driven by the expanding end-of-life vehicle fleet, the growing installed base of aluminium-intensive consumer durables, and construction sector aluminium recycling — but is still insufficient to support the sector at scale. India has historically imported a significant share of its secondary aluminium feedstock. The EU’s Waste Management Regulation, which became effective January 1, 2025 for non-OECD countries, restricts aluminium scrap exports to countries that cannot demonstrate equivalent environmental standards for scrap processing. This regulation has directly tightened the supply of European scrap available to Indian secondary producers. MRAI has called for zero import duty on aluminium scrap to support the sector, arguing that scrap is a critical raw material for India’s decarbonisation — a parallel to the steel sector’s scrap import access challenge. The domestic scrap pool is expected to grow significantly through 2030 as India’s aluminium-intensive infrastructure and vehicle fleet reaches end-of-life, but bridging the near-term supply gap through imports is commercially necessary for sector scaling.
The combined CBAM, CCTS, and energy cost advantages of secondary aluminium versus primary create a commercially compelling investment case for new secondary capacity in India through 2030. A secondary aluminium facility investing in RE-based remelting (gas or electric induction using open-access solar) achieves: GEI of 0.2-0.4 tCO₂/t (below the 0.139 CBAM secondary benchmark when using sufficiently clean energy), CCTS CCC surplus of 0.5-1.1 tCO₂/t per year (generating Rs 400-880 per tonne in CCC revenue at Rs 800/CCC), zero CBAM certificate cost on EU exports (versus €80-800/t for primary), and energy cost 90-95% lower than primary production. Against a capex of approximately Rs 800-1,500 crore for a 100,000-200,000 tpa secondary aluminium facility, these combined returns support payback periods of 5-8 years at current market prices — and the regulatory returns from CBAM and CCTS make the investment case substantially stronger for EU-exporting producers than domestic-only demand would justify.
The CBAM gap — why secondary aluminium has the largest carbon cost advantage in any CBAM product
The EU CBAM provisional benchmark document leaked in December 2025 established two separate emissions benchmarks for aluminium — one for primary production (electrolysis route) and one for secondary production (recycling route). The distinction between the two routes is based on a simple rule: when more than 50% of the aluminium input material is sourced from scrap, the secondary production route benchmark applies. For all other aluminium goods, the primary benchmark applies.
Applies to unwrought un-alloyed aluminium, slabs, billets, and alloys where less than 50% of input is scrap. India’s primary aluminium producers using coal-based captive power plants carry verified GEI of approximately 13-16 tCO₂/t. At the default CBAM rate (for unverified emissions): exposure could be €800/t or higher. At verified emissions of 13.5 tCO₂/t with credit for the 1.464 benchmark: CBAM certificate cost = (13.5 – 1.464) × €60 = €722/t. India’s coal-CPP primary aluminium faces existential CBAM exposure for EU exports.
Applies when more than 50% of aluminium input is sourced from scrap. India’s secondary aluminium producers with gas or RE-based remelting carry GEI of approximately 0.3-0.8 tCO₂/t. Many Indian secondary facilities already operate below the 0.139 secondary benchmark when using efficient remelting processes. CBAM certificate cost at 0.3 tCO₂/t: (0.3 – 0.139) × €60 = €9.7/t — effectively zero. Indian secondary aluminium exporters face near-zero CBAM exposure.
The €712/t CBAM gap between Indian coal-CPP primary (approximately €722/t) and Indian gas-remelting secondary (approximately €10/t) is the largest carbon cost differential in any CBAM-covered product category — larger than the BF-BOF versus scrap-EAF gap in steel, and far larger than in fertilisers or cement. For any Indian aluminium producer currently exporting primary metal to the EU, the strategic question posed by CBAM is existential: either invest in rapid decarbonisation of the primary smelting process (captive solar, open-access RE, CCUS) or pivot capacity toward secondary aluminium where the CBAM exposure is negligible. For the growing secondary aluminium sector, CBAM is not a threat — it is a competitive moat that grows larger every year as EU ETS prices rise.
India’s secondary aluminium sector — production, scrap, and the EU Waste Management constraint
India’s secondary aluminium industry produces approximately 1.5 million tonnes per year of recycled aluminium, making it one of the largest secondary producers in Asia. The sector is fragmented — dominated by small and medium-scale remelters and alloy producers — with Hindalco’s Taloja facility being the most prominent large-scale integrated secondary operation. Secondary aluminium in India serves the automotive sector (aluminium alloy castings for engines, transmission, and chassis components), the packaging sector (aluminium foil and containers), and the construction sector (aluminium profiles and extrusions). These downstream users are increasingly subject to EU green procurement requirements and CBAM-linked supply chain due diligence, creating demand-side pull for certified low-carbon secondary aluminium.
The scrap supply picture is more constrained than the production economics would suggest. India’s domestic aluminium scrap pool is growing — driven by an expanding end-of-life vehicle fleet, the increasing installed base of aluminium-intensive consumer durables, and demolition-related construction scrap — but the informal collection and processing sector lacks the scale and quality control that high-grade secondary aluminium production requires. India has historically supplemented domestic scrap with imports from Europe and the Middle East. The EU’s Waste Management Regulation, effective January 1, 2025 for non-OECD countries, restricts aluminium scrap exports to countries that cannot demonstrate equivalent environmental processing standards. MRAI has called for zero import duty on aluminium scrap, arguing that scrap is a critical raw material for India’s industrial decarbonisation — and that restricting scrap imports while simultaneously mandating lower-carbon production through CCTS creates a policy contradiction that the government must resolve.
The EU Waste Management Regulation, effective January 1, 2025 for non-OECD countries, requires that aluminium scrap exported to non-OECD countries (including India) can only go to facilities that meet equivalent environmental processing and reporting standards — effectively OECD-equivalent standards for scrap processing, environmental controls, and waste management. India’s formal secondary aluminium sector — Hindalco Taloja and a handful of BIS-certified remelters — can likely meet these standards with documentation. But the bulk of India’s secondary aluminium production capacity, concentrated in the informal MSME sector in Rajkot, Jalandhar, and Pune, cannot demonstrate EU-equivalent environmental standards without significant investment in facility upgrades, monitoring, and certification. This means the EU Waste Management Rule effectively restricts premium European scrap to only the formal, certified segment of India’s secondary sector — potentially tightening the scrap supply for the exact facilities that are best positioned to capture the CBAM advantage on EU exports. The policy response required: rapid BIS certification expansion for secondary aluminium facilities, investment in formal scrap collection infrastructure (analogous to authorised vehicle scrapping centres for steel), and engagement with the EU on recognition of India’s CCTS MRV framework as equivalent for scrap export eligibility.
CCTS targets for secondary aluminium — the January 2026 gazette
Secondary aluminium was included in the final GHG Emission Intensity Target Rules gazette notification on January 16, 2026 — the same notification that finalised targets for petroleum refinery, petrochemicals, and textiles. The inclusion of secondary aluminium in CCTS Phase 1 confirms that the sector is a designated obligated entity for FY2025-26 and FY2026-27 compliance. The targets are calibrated to the sector’s actual emission intensity — which is dramatically lower than primary aluminium — rather than requiring primary-level performance.
| Entity | Production (FY2023-24) | Baseline GEI (tCO₂/t) | Phase 1 target FY2025-26 (est) | Phase 2 target FY2026-27 | CCC position |
|---|---|---|---|---|---|
| Hindalco Taloja (Maharashtra) | Largest India secondary Al facility | 1.3386 tCO₂/t | ~1.32 tCO₂/t (est.) | 1.2563 tCO₂/t | Likely modest CCC surplus if efficiency improvements made |
| Other formal secondary producers | Various — total sector ~1.5 Mt/yr | 0.3-1.5 tCO₂/t depending on energy source | Sector-specific targets per gazette | Targets tightening ~6% from baseline | Most well-performing facilities: CCC surplus position |
| RE-based secondary remelting | Emerging; not yet dominant | 0.2-0.4 tCO₂/t | Below CBAM secondary benchmark 0.139 tCO₂/t | Target trajectory: below 0.3 tCO₂/t | Strong CCC surplus — 0.8-1.1 tCO₂/t above Phase 2 target |
The critical commercial implication is that CCTS compliance for secondary aluminium is not a burden — it is a revenue source. A secondary aluminium facility operating at 0.3 tCO₂/t with a Phase 2 CCTS target of approximately 1.26 tCO₂/t has an outperformance of approximately 0.96 tCO₂/t. At Rs 800 per CCC and 100,000 tpa production: Rs 76.8 crore per year in CCC revenue. For a 200,000 tpa secondary facility: Rs 153.6 crore per year. This CCC revenue stream is on top of the CBAM near-zero certificate cost advantage on EU exports — creating a dual regulatory tailwind that the primary aluminium sector cannot access without transformational capital investment.
The investment case — why secondary aluminium deserves priority capital in India’s decarbonisation plan
The combined financial returns from CBAM advantage, CCTS CCC surplus, and energy cost savings make secondary aluminium one of the highest-return decarbonisation investments available to Indian industry. The following return model is based on a 100,000 tpa new-build secondary aluminium facility using gas-based induction remelting.
| Return component | Basis | Annual value |
|---|---|---|
| Energy cost saving vs primary | Secondary uses ~0.7 GWh/t vs primary 14 GWh/t. At Rs 6.5/kWh: savings of Rs 85,800/t. Not directly comparable (different products) but positions cost competitiveness. | N/A — structural advantage |
| CBAM near-zero certificate cost on EU exports | Primary coal-CPP pays ~€722/t CBAM on EU exports; secondary at 0.3 tCO₂/t pays ~€10/t. For 30,000 tpa EU exports from a 100,000 tpa facility: saving vs primary = €712 × 30,000 = €21.4M | Rs ~189 crore/year saving vs primary competitor |
| CCTS CCC revenue (outperformance of CCTS target) | GEI 0.3 tCO₂/t vs Phase 2 target ~1.26 tCO₂/t: surplus 0.96 tCO₂/t × 100,000 t × Rs 800/CCC | Rs 76.8 crore/year in CCC income |
| Green aluminium market premium | EU buyers paying €50-150/t premium for certified low-carbon aluminium (CBAM-compliant, ResponsibleAl certified). At €80/t average on 30,000 tpa EU exports | Rs ~21 crore/year |
| Total regulatory + market premium return | CBAM saving + CCC income + green premium | Rs 287 crore/year (for 100,000 tpa EU-exporting secondary facility) |
| Indicative capex for 100,000 tpa secondary facility | Rs 800-1,200 crore (new build, gas induction remelting, scrap preparation, casting) | Payback: 2.8-4.2 years at Rs 287 crore/year return |
The payback period of under 5 years for a new secondary aluminium facility, driven largely by CBAM and CCTS regulatory returns, is materially better than most industrial capital investments in India’s decarbonisation space. The key risk remains scrap supply — at full utilisation, a 100,000 tpa secondary facility requires approximately 105,000-110,000 tpa of aluminium scrap input (allowing for approximately 5-10% melt loss). Securing long-term scrap supply agreements — domestically from ELV scrapping centres and aluminium-intensive construction demolition, and through strategic import partnerships with compliant OECD recyclers — is the primary pre-investment requirement that determines whether the financial model is executable.
Frequently Asked Questions
What is the CBAM benchmark for secondary aluminium and how does it compare to primary?
The EU CBAM provisional benchmark for secondary aluminium is 0.139 tCO₂e per tonne — applying when more than 50% of the aluminium input is sourced from scrap. The primary aluminium benchmark is 1.464 tCO₂e per tonne. The gap of 1.325 tCO₂e per tonne translates to approximately €79/t in CBAM certificate cost difference at EU ETS prices of €60/tCO₂e. For India’s coal-CPP primary aluminium producers, the gap is far larger: at verified GEI of approximately 13.5 tCO₂/t, the CBAM certificate cost on EU exports is approximately (13.5 – 1.464) × €60 = €722/t, while Indian secondary aluminium at 0.3 tCO₂/t carries approximately (0.3 – 0.139) × €60 = €10/t — a practical difference of €712/t. This is the largest carbon cost differential in any CBAM-covered product category.
What are India’s CCTS targets for secondary aluminium and when were they notified?
Secondary aluminium was included in the final GHG Emission Intensity Target Rules gazette notification on January 16, 2026 — along with petroleum refinery, petrochemicals, and textiles. Hindalco Industries’ Taloja secondary aluminium plant (Maharashtra), India’s largest secondary facility, carries a baseline GEI of 1.3386 tCO₂/t from FY2023-24 data, with a Phase 2 target of 1.2563 tCO₂/t by FY2026-27. Secondary aluminium facilities that operate at 0.3-0.8 tCO₂/t — well below the notified targets — will generate large CCTS CCC surpluses. At 0.3 tCO₂/t versus a Phase 2 target of approximately 1.26 tCO₂/t, a 100,000 tpa secondary facility earns approximately 0.96 × 100,000 = 96,000 CCCs per year — worth approximately Rs 76.8 crore at Rs 800/CCC. CCTS is a revenue opportunity for secondary aluminium, not a compliance burden.
What is restricting India’s secondary aluminium scrap supply and what is the policy solution?
Two constraints: (1) Domestic scrap pool is growing but fragmented and insufficient at scale — India’s aluminium-intensive infrastructure and vehicle fleet is generating increasing end-of-life scrap but formal collection and processing infrastructure (analogous to authorised vehicle scrapping centres) is underdeveloped. (2) The EU’s Waste Management Regulation, effective January 1, 2025 for non-OECD countries, restricts premium European aluminium scrap exports to facilities that cannot demonstrate EU-equivalent environmental processing standards — limiting access for most of India’s informal MSME secondary sector. MRAI has called for zero import duty on aluminium scrap. The policy solution requires: rapid BIS certification expansion for Indian secondary aluminium facilities; investment in formal scrap collection infrastructure; and engagement with the EU on recognition of India’s CCTS MRV framework as demonstrating equivalent environmental standards for scrap export eligibility.
