Zinc and lead remain essential to Europe’s industrial base, although they receive less strategic attention than lithium and rare earth elements. Both metals are used in critical manufacturing, from galvanised steel and corrosion protection to batteries, backup power systems and specialised industrial applications. However, the energy-intensive refining of these metals falls 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 highlights a gap in Europe’s industrial decarbonisation framework. Domestic refiners must comply with energy, environmental and carbon requirements. Imported zinc and lead, by contrast, do not incur CBAM charges simply because they enter the market as refined metals.
Energy and compliance costs pressure European refiners
Zinc refining comprises several energy-intensive stages, including roasting, leaching, purification and electrowinning. Electricity costs are a significant part of production expenses, making reliable power at competitive prices important to plant economics. Lead production uses smelting furnaces and fuels, while secondary processing increasingly handles complex feedstocks from used batteries and industrial scrap.
Lead and zinc operations must also manage environmental controls and compliance obligations, adding to the cost pressures on European facilities. Domestic producers bear these expenses while overseas suppliers may operate under different energy and regulatory conditions. Since refined zinc and lead are outside CBAM’s current scope, their carbon intensity is not directly priced at the EU border through the mechanism.
Customers may still demand sustainability reporting, recycled content or other environmental standards. 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 strengthening Europe’s zinc and lead supply security. Lead-acid batteries are served by a mature closed-loop recycling system, which allows 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 improve the resilience of European refining chains. Secondary processing can also increase resource efficiency, although its economic benefits depend on feedstock availability, processing technology and operating costs. Reliable access to recycled materials can therefore 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 sustain 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 become particularly important 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 review of CBAM could change the competitive environment. Investment assessments should nevertheless reflect the rules currently in force, rather than assume zinc and lead will eventually receive equivalent border protection.
CBAM coverage leaves refining outside the border framework
The zinc and lead sectors illustrate 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 some covered industries.
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.
