Europe’s efforts to strengthen mineral supply security extend beyond mining, as energy-intensive refining and smelting operations face competitive pressure from differences in electricity prices and carbon costs between regions. While mineral concentrates can be traded internationally, processing facilities are fixed industrial assets that require substantial capital and long payback periods.
When operating costs diverge between markets, processing capacity can relocate even if the underlying mines remain in operation. This creates a challenge for Europe as it seeks to retain and rebuild domestic capacity across critical mineral supply chains.
CBAM Coverage Leaves Several Refined Metals Exposed
The Carbon Border Adjustment Mechanism (CBAM) is designed to address carbon-cost differences affecting imports of products such as aluminium and steel. However, most refined products derived from copper, zinc, lead, nickel, lithium, graphite and rare earths remain outside its current scope.
This creates a policy challenge for European processing projects seeking to compete with imported materials while managing domestic carbon and electricity costs.
Refining also captures value beyond raw mineral extraction by producing materials that meet downstream industrial specifications. The sector relies on traceability, impurity management, recycling and product quality, while the loss of processing capacity can increase dependence on foreign conversion infrastructure and industrial expertise.
Electricity Costs Influence Refinery Competitiveness
Electric furnaces, electrowinning, electrolysis, grinding, separation and high-temperature processing can make energy procurement a major determinant of refinery margins. European projects can manage exposure through renewable power purchase agreements (PPAs), self-generation, energy storage and process electrification, although these measures require capital investment and long-term contracts.
Competing refineries in third countries may benefit from lower electricity costs without facing an equivalent carbon charge when their products enter the EU market.
Policy Support and Financing Requirements
A broader CBAM is not the only available policy option. Recycling requirements, strategic procurement, long-term offtake agreements, grants and permitting reform can also support the development of European refining capacity.
Where a specific processing activity falls under the EU Emissions Trading System (EU ETS) and faces demonstrable competition from carbon-intensive imports, the absence of a corresponding border adjustment remains a relevant consideration.
For lenders, refinery assessments increasingly need to account for energy-price sensitivity, EU ETS exposure, imported-product competition, customer carbon specifications and potential future CBAM inclusion. While mining secures access to mineral resources, refining determines how much downstream industrial value Europe retains.
