Zinc and lead remain important to Europe’s industrial base, although they receive less strategic attention than lithium and rare earth elements. They are used in manufacturing applications ranging from galvanised steel and corrosion protection to batteries, backup power systems and specialised industrial uses. However, the energy-intensive refining of both metals falls outside the current scope of the EU Carbon Border Adjustment Mechanism (CBAM), leaving European producers exposed to carbon and operating costs that are not directly reflected in border charges on imported refined metal.
This exclusion highlights a gap in Europe’s industrial decarbonisation framework. Domestic refiners must comply with energy, environmental and carbon requirements, while imports of refined zinc and lead do not incur CBAM charges simply because they are supplied in those forms. Their producers therefore face different cost conditions from industries whose products are covered by the mechanism.
Energy and compliance costs pressure European refiners
Zinc refining uses energy at several stages, including roasting, leaching, purification and electrowinning. Electricity is a significant production cost, making reliable access to competitively priced power important to plant economics. These requirements add to the operating pressures on European facilities.
Lead production uses smelting furnaces and fuels. Secondary processing increasingly handles complex feedstocks from used batteries and industrial scrap, and must also meet environmental-control and compliance obligations. These requirements add to the costs faced by European lead producers.
European refiners absorb these expenses while overseas suppliers operate under different energy and regulatory conditions. Since refined zinc and lead are outside the current CBAM scope, the carbon intensity of those imports 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 does for covered products such as steel and aluminium.
Recycling supports supply security
Recycling is a key tool for improving Europe’s zinc and lead supply security. Lead-acid batteries are supported by a mature closed-loop recycling system, through which recovered lead can re-enter production. Zinc can be recovered from galvanised steel residues, electric-arc-furnace dust and other secondary material streams.
Combining recycled feedstock with primary materials can reduce dependence on imported concentrates and strengthen the resilience of European refining chains. Secondary processing can also improve resource efficiency, although its economic benefits depend on feedstock availability, processing technology and operating costs. Reliable access to recycled materials can give refiners a supply-chain advantage and help manage exposure to volatile raw-material markets.
Refining margins shape investment risk
For lenders and investors, a central concern is whether European plants can maintain 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.
Facilities with efficient operations, diversified feedstock supplies and established customer relationships may be better placed to absorb cost pressures than plants reliant on expensive imported concentrates or less flexible production models. A future CBAM review could change the competitive environment. Investment assessments should nevertheless be based on rules currently in force, rather than assuming that zinc and lead will eventually receive equivalent border protection.
CBAM coverage leaves gaps for metal refining
The zinc and lead sectors show a wider challenge for European industrial policy: carbon costs apply across industrial supply chains, but CBAM coverage remains selective. Refiners outside the mechanism must manage energy expenditure, environmental compliance and international competition without the same border-adjustment framework available to some covered industries. The current system therefore leaves these producers exposed to costs that are not addressed through CBAM charges on imports of refined metal.
Strengthening recycling, securing affordable low-carbon power and improving production efficiency 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.
