Mercedes bets on green aluminium from Norway's Hydro for next-gen CLA

Mercedes aluminium body

Mercedes is turning to green aluminium from Norway's Hydro to cut embedded emissions in its new CLA model. The green aluminium from Norway's Hydro is certified at just 3kg of CO₂ per kilogram of metal across mining, refining, smelting and casting. This compares with a global average of 16.7kg, giving Mercedes a meaningful reduction in material-related emissions. The alloy also contains 25pc post-consumer scrap, which further lowers its lifecycle footprint and supports circular-economy targets.

However, the company’s claim that CLA production is “net carbon-neutral” still depends on offsets. Mercedes powers the plant with 100pc renewable electricity, mainly externally sourced hydropower, which materially cuts scope 2 emissions. But scope 1 emissions from on-site processes and logistics, as well as upstream emissions from suppliers, remain. Therefore, the move to green aluminium from Norway's Hydro is a genuine step forward, even if the overall net-zero claim rests partly on controversial offset mechanisms that investors often scrutinise.

Green aluminium supports low-carbon steel and battery initiatives

The CLA’s use of green aluminium from Norway's Hydro forms part of a broader materials decarbonisation strategy. Mercedes says its latest battery cell design cuts emissions by about 30pc per cell through renewable energy in anode and cathode production. The company also relies on “net carbon-neutral” cell manufacturing at suppliers, since it does not produce cells in-house. As a result, the true impact depends on supplier practices and verification of their renewable power usage.

Meanwhile, Mercedes is layering in low-carbon steel to tackle emissions in chassis and body-in-white applications. The CLA incorporates steel from US producer Nucor’s Econiq-RE range, made using 100pc renewable energy. Mercedes also has a deal with Steel Dynamics for more than 50,000 t/yr of CO₂-reduced steel for its Tuscaloosa plant. Together with green aluminium from Norway's Hydro, these supply contracts show how OEMs are weaponising procurement to reduce embodied carbon ahead of incoming carbon border measures.

Demand for certified green aluminium rises faster than headline prices

Demand for certified low-carbon aluminium is rising as automakers prepare for tighter climate regulations and potential carbon border charges. Carmakers want to cut embedded emissions at the material level, especially for high-intensity metals such as aluminium and steel. This is likely to support growing premiums for Hydro’s Reduxa-style green aluminium grades and similar products from competitors. As a result, upstream smelters with renewable power and high scrap usage gain a strategic pricing advantage.

However, headline aluminium prices on global exchanges remain relatively stable despite bullish long-term forecasts. London Metal Exchange cash aluminium has traded in a narrow range over the past year, even as demand for differentiated “green” material accelerates. This suggests that the value is migrating into contract premiums and long-term offtake deals instead of the base price. Over time, producers unable to demonstrate low-carbon credentials may find themselves pushed into a discounted “grey” segment of the market.

The Metalnomist Commentary

Mercedes’ partnership around green aluminium from Norway's Hydro shows how decarbonisation is increasingly driven by procurement, not just tailpipe regulation. For metals producers, the message is clear: access to cheap renewable power and high-quality scrap streams will shape competitiveness more than pure tonnage growth. As carbon accounting tightens, the premium for verifiable low-carbon tonnes is likely to widen, rewarding early movers across the aluminium value chain.
