Europe’s debate over mining and critical raw materials often focuses on access to mineral deposits, but another strategic vulnerability lies further along the supply chain: energy-intensive refining and processing. While mineral concentrates can move across international markets, smelters and refineries are fixed industrial assets requiring substantial capital and long investment horizons. Differences in electricity prices and carbon costs can therefore influence where processing capacity develops and whether existing facilities remain competitive.
This creates a challenge for Europe as it seeks to strengthen domestic supply chains for copper, zinc, lead, nickel, lithium, graphite and rare earths. Many refined products from these sectors remain outside the current scope of the Carbon Border Adjustment Mechanism (CBAM), leaving questions about how effectively European processing facilities can compete with overseas producers.
Refining Is Critical to Europe’s Industrial Strategy
Mineral processing and refining generate value beyond the extraction of raw materials. These activities convert concentrates and other feedstocks into products with the chemical composition, purity and technical specifications required by manufacturers.
Refineries also play an important role in recycling, impurity management, material traceability and product quality. Losing domestic processing capacity can therefore leave Europe dependent not only on foreign mineral supplies, but also on overseas conversion infrastructure and industrial expertise.
Although CBAM addresses carbon leakage in selected sectors such as steel and aluminium, many non-ferrous metals and critical-mineral products remain outside its direct coverage. This creates a policy challenge for European producers seeking to expand refining capacity while competing against imports that may not face an equivalent border carbon charge.
Electricity Prices and Carbon Costs Shape Refining Economics
Energy consumption is a major factor in the competitiveness of many processing operations. Electric furnaces, electrowinning, electrolysis, grinding, separation and high-temperature treatment can make electricity procurement a decisive influence on operating margins.
European projects can reduce exposure through renewable power purchase agreements, on-site generation, energy storage and process electrification. These solutions require additional investment, suitable infrastructure and, in many cases, long-term contractual commitments.
Overseas competitors may benefit from lower energy costs and different carbon-related obligations. Where imported products are not covered by CBAM, European refiners can face additional competitive pressure even when their operations comply with the EU’s environmental requirements. The consequences extend beyond individual facilities. If investment shifts toward regions with lower production costs, Europe risks losing industrial capacity needed to supply manufacturers and support its energy transition.
CBAM Is Only One Part of the Solution
Extending CBAM is not necessarily the most effective response for every mineral or refining activity. Its scope is designed around specific products and carbon-leakage risks, so broader coverage would require a clear regulatory justification.
Other measures could strengthen the economics of European processing, including recycling requirements, strategic procurement, long-term offtake agreements, investment grants and faster permitting. These instruments could help projects secure feedstock, attract capital and establish reliable markets for refined products.
Nevertheless, where a particular refining activity faces EU Emissions Trading System (ETS) costs and demonstrable competition from carbon-intensive imports, the absence of corresponding border adjustment may become an increasingly important policy issue. A balanced approach would need to support industrial decarbonisation without unnecessarily increasing costs for European manufacturers that depend on imported metals and minerals.
Refinery Investment Requires More Detailed Risk Assessment
For lenders and investors, evaluating a processing project increasingly requires more than assessing mineral reserves, production capacity and commodity prices.
Financial models should account for electricity-price volatility, EU ETS exposure, competition from imported products, customer carbon requirements and the possibility of future CBAM changes. Developers must also consider the capital needed for cleaner technologies and the commercial value of traceable, lower-emission materials.
Long-term power contracts and offtake agreements can reduce uncertainty, but they do not eliminate the risks associated with changing trade rules or shifts in international production costs. These factors are particularly important for projects involving copper, nickel, zinc, lithium and other materials that Europe considers essential to its industrial and technological development.
Europe’s critical-minerals challenge extends beyond securing deposits. The long-term competitiveness of its raw-material supply chains will depend on whether domestic refineries can operate economically, meet environmental requirements and compete with international suppliers. The mine may secure access to resources, but the refinery determines how much industrial value Europe retains from them.
