CBAM for Aluminium Exporters
Carbon Border Adjustment Mechanism (CBAM) compliance for exporters of aluminium to the European Union, worldwide, and for the EU importers who declare them. Embedded emissions of unwrought aluminium and aluminium products calculated from installation data, CBAM reports prepared for verification by accredited verifiers, and certificate exposure estimated and managed, as one accountable engagement delivered from Mumbai.

What CBAM means for aluminium exporters
Aluminium supply into the EU is global, and only direct emissions are priced.
The Carbon Border Adjustment Mechanism (CBAM) prices the carbon emissions embedded in imported goods, and aluminium is one of the six covered product groups. The European Union imported about 29.5 billion euro of aluminium and aluminium products in 2024. Its three largest suppliers, Norway, Iceland and Switzerland, sit in the European Economic Area or a linked emissions trading system and fall outside CBAM under Annex III, so the definitive regime, in force since 1 January 2026, reprices market access for the in scope suppliers that follow them, led by China, Türkiye and the Gulf.
Among the suppliers CBAM actually prices, China and Türkiye lead, with the Gulf states also material. India is a mid-tier supplier to the EU and, at the same time, one of the largest primary aluminium producers in the world through Hindalco, Vedanta and Nalco. GreenSutra works as a CBAM consultant for aluminium exporters across India and worldwide, and the EU importers and authorised declarants who file for them.
Exposure tracks the production route and the country of origin. The table below shows the leading suppliers of aluminium to the EU and how CBAM bears on each.
| Market | Aluminium to the EU, 2024 | CBAM exposure |
|---|---|---|
| Norway | €4.4 billion, the largest supplier | In the EEA and the EU ETS, so outside CBAM under Annex III, whatever its hydro powered emissions. |
| China | €3.9 billion | The highest direct emissions intensity of the major routes, so the most exposed on a per tonne basis under direct only accounting. |
| Türkiye | €2.8 billion | A mixed route supply, exposure set by the specific installation. |
| Iceland | €2.1 billion | In the EEA and the EU ETS, so outside CBAM under Annex III. |
| India | Around €1 billion, a mid-tier supplier | A major global primary producer; direct emissions sit modestly above the EU benchmark, so verified data matters. |
Import values from Eurostat, 2024 (aluminium and articles). Because aluminium is priced on direct emissions only, the electricity behind a smelter is excluded, so a coal grid does not by itself raise the current certificate cost, though it would if the scope were extended to indirect emissions. The CBAM cost of any specific installation turns on its route and verified emissions, so the figures above frame exposure rather than fix a bill. A first step is the structured CBAM discovery brief, after which exposure feeds the CBAM cost calculator. The full deadlines and methods are set out in the CBAM compliance guide.
Aluminium products and their default values
The India default embedded-emissions values that apply where verified data is not supplied.
Coverage follows the combined nomenclature (CN) code of each good, from unwrought aluminium through bars, rods, wire, plates, sheets, strip, foil, tubes and structures. The India defaults below count direct emissions only, and each carries a mark-up of 10 percent in 2026, 20 in 2027 and 30 from 2028.
The representative values below span the aluminium range. Each is a single country-of-origin default; the figure for a specific installation turns on whether the metal is primary or recycled and, where supplied, its verified emissions.
Reading down the table, the default climbs with each stage of working, from 1.87 tonnes of CO2e per tonne for unwrought aluminium to 4.13 for plates, sheets and strip. Set against the tonnage a supplier ships to the European Union, that spread is what fixes the scale of a certificate position, before verified installation data brings the declared figure below the default.
| Product | Representative CN | India default (tCO2e/t) |
|---|---|---|
| Unwrought aluminium | CN 7601 | 1.87 |
| Bars and rods | CN 7604 10 10 | 3.41 |
| Plates, sheets and strip | CN 7606 | 4.13 |
Values are the India direct-emissions defaults, specific to the country of origin, so the set differs elsewhere. Source: Implementing Regulation (EU) 2025/2621, Annex I. Wrought products carry more embedded emissions than unwrought metal because of the further processing. Estimate a specific product, volume and route in the CBAM cost calculator.
How an aluminium CBAM engagement runs
From exposure assessment to a prepared, declared and managed certificate position.
Assess CBAM exposure
Aluminium products, CN classification, production route, export destinations and volumes mapped against the definitive regime, the de minimis threshold and the authorised declarant requirement.
Calculate embedded emissions
Direct embedded emissions of each product quantified from actual installation and production route data following the EU methodology, in place of default values that carry a mark-up, then prepared for verification.
Prepare for accredited verification
Installation data and the monitoring methodology behind it prepared for confirmation by an accredited verifier, so the declared embedded emissions stand on evidence rather than marked up default values.
Report through the CBAM registry
Verified data shared with EU importers and authorised declarants through the central CBAM registry, and the annual declaration prepared so every covered consignment is accounted for.
Manage CBAM exposure and reduce
Certificate exposure tracked against the EU ETS price, any carbon price paid at origin deducted, and a reduction pathway built to lower the embedded emissions and the cost over time.
How CBAM works for aluminium
The border mechanism follows the embedded emissions of an aluminium good from the smelter across the European border to the certificate that is surrendered.
A smelter or plant produces an aluminium good. Primary metal from ore carries far more embedded carbon than recycled, scrap based metal.
The direct embedded emissions are measured from installation data, or estimated with a country and product specific default value that carries a mark-up. Indirect, electricity related emissions are not priced for aluminium, so the grid mix behind a smelter does not add to the certificate obligation.
An accredited verifier confirms the actual data, which is shared with the European importer through the central CBAM registry.
The good crosses the European border, where an authorised CBAM declarant reports the embedded emissions for the year above the 50 tonne de minimis.
CBAM certificates are surrendered for the direct embedded emissions, priced off the EU ETS, with any carbon price already paid at origin deducted.
Direct embedded emissions are measured at the smelter, verified and shared through the CBAM registry, then declared at the European border by an authorised declarant who surrenders certificates priced off the EU ETS. Aluminium is an Annex II good, so only direct emissions are priced and the electricity behind the smelter is excluded. First surrender, covering 2026 imports, falls on 30 September 2027.
Embedded emissions follow each aluminium product from the smelter to the European border, and a readiness review turns that path into a measured, verified compliance plan.

The gains of moving from marked up default values to verified installation data.
Market access retained
Verified embedded emissions data keeps aluminium products moving into the European market under the definitive regime without compliance friction.
Lower certificate cost
Actual verified data replaces the conservative default, so the certificate obligation reflects the real production route rather than a penalty estimate.
Trusted supplier status
Sharing verified data through the CBAM registry positions the smelter as a preferred supplier to European importers and declarants.
Decarbonisation advantage
A reduction pathway lowers embedded emissions over time, an advantage that grows as the payable share climbs toward 100 percent in 2034 and if the scope later widens to indirect emissions.
