Zinc refining and lead production remain important to Europe’s industrial base, despite receiving less strategic attention than lithium and rare earth elements. Both metals are used in manufacturing, including galvanised steel and corrosion protection, batteries, backup power systems and specialised industrial applications. However, their energy-intensive refining is outside the current scope of the EU Carbon Border Adjustment Mechanism (CBAM), leaving European producers with carbon and operating costs that are not directly reflected in border charges on imported refined metal.
This creates a gap in Europe’s industrial decarbonisation framework. Domestic refiners must meet energy, environmental and carbon-compliance requirements, while imports of refined zinc and lead do not incur CBAM charges simply because they are supplied as those metals.
Energy and compliance costs weigh on European refiners
Zinc refining includes several energy-intensive stages: roasting, leaching, purification and electrowinning. Electricity supply is a significant production cost, so reliable power at competitive prices matters to plant economics.
Lead production uses smelting furnaces and fuels. Secondary processing increasingly handles complex feedstocks from used batteries and industrial scrap, while facilities must also manage environmental controls and compliance obligations. These requirements add to the cost pressures on European plants.
European producers face a competitive challenge when they absorb these costs while overseas suppliers operate under different energy and regulatory conditions. Refined zinc and lead remain outside the current CBAM scope, so their carbon intensity is not directly priced at the EU border through the mechanism. Customers may still require sustainability reporting, recycled content or other environmental standards, but these commercial requirements do not provide the same direct carbon-cost signal as CBAM coverage for products such as steel and aluminium.
Recycling supports supply security
Recycling is a key tool for strengthening Europe’s zinc and lead supply security. Lead-acid batteries are supported by a mature closed-loop recycling system, allowing recovered lead to return to production. Zinc can also be recovered from galvanised steel residues, electric-arc-furnace dust and other secondary material streams.
Combining recycled feedstock with primary materials can reduce reliance on imported concentrates and make European refining chains more resilient. Secondary processing can improve resource efficiency, although its economic benefits depend on feedstock availability, processing technology and operating costs. Reliable access to recycled materials can therefore provide refiners with a supply-chain advantage and help them manage exposure to volatile raw-material markets.
Margins are central to investment assessments
For lenders and investors, a central concern is whether European plants can preserve adequate margins between global metal prices and local operating expenses. Low-carbon electricity contracts, by-product revenues, recycling feedstock, environmental performance and proximity to customers can all affect a refinery’s financial resilience.
These factors matter particularly when metal prices or processing margins weaken. Plants with efficient operations, diversified feedstock supplies and established customer relationships may be better placed to absorb cost pressures than facilities reliant on expensive imported concentrates or less flexible production models. A future CBAM review could change the competitive environment, but investment assessments should reflect the rules currently in force rather than assume zinc and lead will eventually receive equivalent border protection.
CBAM coverage remains selective
The zinc and lead sectors highlight a broader challenge for European industrial policy: carbon costs apply across industrial supply chains, while CBAM coverage remains selective. Refiners outside the mechanism must manage energy expenditure, environmental compliance and international competition without the border-adjustment framework available to certain covered industries.
Recycling, access to affordable low-carbon power and more efficient production will remain central to the competitiveness of Europe’s zinc and lead refining industries. Carbon-border measures alone cannot resolve the structural pressures facing metal producers whose products remain outside the current system.
