Europe’s efforts to strengthen industrial independence depend on retaining domestic processing capacity as well as securing raw materials. Under the current EU Carbon Border Adjustment Mechanism (CBAM), copper, zinc, lead and refined nickel smelters face carbon and energy costs that are not necessarily matched by equivalent border adjustments on imported metals. The question is how to sustain that processing capacity without relying on an expansion of CBAM alone.
European smelters and refineries take in recycled materials, retain technical expertise and supply downstream manufacturers with metals that meet industrial specifications. Domestic processing also limits dependence on facilities abroad, particularly in regions that control both raw-material production and refining. The EU Critical Raw Materials Act (CRMA) recognises processing and recycling as parts of strategic supply chains, but strategic project designation does not by itself establish financial viability.
Operating Costs and Investment Measures
Smelters are capital-intensive operations exposed to electricity prices, maintenance costs, volatile treatment and refining charges, and environmental compliance requirements. When operating costs in Europe are higher than in competing regions, the absence of equivalent CBAM coverage can make investment decisions more difficult. Without a consistent framework for competitiveness, Europe could support new mines while continuing to import higher-value refined products.
Expanding CBAM is one possible response, alongside measures to strengthen metal processing directly. Long-term renewable electricity contracts, waste-heat recovery, process electrification and recycling can improve efficiency and reduce reliance on imported concentrates. Valuable by-products can add revenue.
Government support through faster permitting, targeted grants, contracts for difference and infrastructure investment could help strategic projects secure financing. Long-term offtake agreements can make revenue more predictable, while demand for traceability and documented environmental performance may offer further commercial opportunities. Whether these measures can sustain margins throughout the commodity cycle remains the central challenge: public support cannot replace competitive operating costs and a commercially viable business model.
Considerations for CBAM Coverage
The case for expanding CBAM depends on where differences in carbon costs are large enough to undermine European production. Any extension would need to account for emissions, international competition and the effects on downstream manufacturers that rely on affordable metal inputs. Keeping domestic refining viable while decarbonising industry would require competitive energy, recycling, investment support and carefully designed trade measures, rather than CBAM alone.
