Automotive, packaging and industrial buyers are increasingly seeking lower-carbon aluminium. This demand creates opportunities for producers to secure a customer premium for renewable-powered material before electricity-related emissions treatment changes under the EU Carbon Border Adjustment Mechanism (CBAM). The timing is linked to how CBAM will treat electricity-related emissions in the future.
CBAM scope and the role of purchased renewable electricity
For iron-and-steel and aluminium goods currently listed in Annex II, the existing CBAM calculation takes account of direct emissions. Renewable electricity procurement can deliver operating, commercial, financing and decarbonisation benefits without automatically reducing current CBAM certificate liability for these goods through purchased-electricity emissions. This means renewable power procurement does not automatically change certificate liability under the current calculation approach.
The distinction allows aluminium producers to pursue customer demand for lower-carbon products independently of any future changes to CBAM calculations. The commercial value depends on whether buyers are prepared to pay for claimed environmental characteristics and whether those characteristics can be documented. Documentation requirements therefore affect whether premiums can be supported in practice.
Renewable electricity can support a lower-carbon product proposition when the supplier can demonstrate the generating source. Suppliers also need to show ownership of associated attributes and their allocation to production. Customer-facing claims should specify what is being measured rather than rely on an unrestricted zero-carbon label.
Contracts, evidence and responsibility for emissions reporting
Power traders and independent power producers (IPPs) can support aluminium producers by supplying long-term electricity. They can also provide Guarantees of Origin (GoOs), generating-source data and structured documentation. The aluminium producer retains responsibility for its product-level emissions reporting.
Premiums established through binding customer contracts should be distinguished from expectations based on marketing. A signed low-carbon supply agreement with measurable specifications provides a more concrete basis for assessing revenue potential than an assumption that customers will pay more for aluminium produced using renewable electricity. This approach ties commercial claims to contractual terms and measurable requirements.
The financing case is described as stronger when a power purchase agreement (PPA) improves operating competitiveness under current market conditions. The same contract should preserve flexibility for future policy developments. The contract should not depend on anticipated CBAM changes to justify its commercial rationale.
Electricity access for new aluminium capacity
For new aluminium capacity, access to competitive low-carbon electricity can influence site selection alongside labour availability and logistics. Electricity-market structures and grid development therefore have a direct role in the regional investment case for aluminium production. These factors affect how projects are evaluated during capacity planning.
The commercial assessment should separate the cost advantages of electricity procurement from compliance with product-level emissions requirements. Each decarbonisation measure needs to be financed according to the benefits it can demonstrably deliver. This separation is intended to align investment decisions with both cost and compliance considerations.
Downstream CBAM expansion from 2028
A legislative file proposing changes to CBAM also includes a downstream expansion from 2028. The expansion would cover selected steel- and aluminium-intensive goods. Both the Council of the EU and the European Parliament support an expansion, but their proposed product lists differ and remain subject to negotiation.
Until final legislation is adopted, the existing CBAM scope remains the operating baseline. Customer demand for lower-carbon aluminium can generate commercial value before regulatory treatment changes, provided that product claims are specific, measurable and supported by evidence that withstands procurement scrutiny. Evidence requirements therefore remain central to how claims translate into premiums.
