An LME-linked pricing agency, Commodity Pricing and Analysis Ltd, has published its first premiums for sustainable copper and aluminium. It set the copper premium at zero, saying it found limited evidence that buyers pay extra for sustainable cathode over standard Grade A material. That stands in contrast to producers like Montanwerke Brixlegg, which is marketing copper with 0.63 tonnes of carbon per tonne of metal at a premium of 398 euros per tonne for 2027. For aluminium, CPAL set a sustainable premium of $25 to $35 per tonne over the standard P1020A Rotterdam premium, for metal with 8 tonnes or less of carbon per tonne. That is broadly in line with Fastmarkets' low-carbon premium of $22.50, even though Fastmarkets uses a stricter 4-tonne threshold. CPAL based both initial premiums on market assessments, not executed trades, because no trades or firm bids were available on platforms. The launch gives buyers and sellers a reference point for low-carbon metals, but the gap between the zero copper premium and real-world deals shows the benchmark still needs more trading activity to be representative. For anyone tracking industrial decarbonization, this is one to watch.
