London Exchange Agency Struggles for Green Metal Trade Data

A London Metal Exchange-linked agency, Commodity Pricing and Analysis Ltd (CPAL), is encountering difficulties in collecting actual trading data for sustainable metals. The initiative, announced a year ago, aimed to publish premiums based on real trades, but current assessments for aluminum and copper premiums have relied on market conversations instead. This stems from participant reluctance to share sensitive trading details, a concern echoed by the LME's collaboration partner, Metalshub, which requires customer approval before sharing any transactional data. CPAL hopes to secure this approval in the future to strengthen premium calculations.

The agency's initial assessment that sustainable copper commands no premium has ignited controversy. Some European producers argue that CPAL's broad definition of low-carbon copper, using a global average of 4 tons of carbon emissions per ton of metal, inaccurately represents their high-value green metals. For instance, Austrian smelter Montanwerke Brixlegg offers copper with significantly lower emissions (0.63 tons/ton) at a premium of €398 ($446) per ton for 2027 delivery. CPAL acknowledges using a higher CO2 threshold initially to encourage broader participation, stating their definition encompasses various environmental and labor factors beyond just carbon emissions.

CPAL plans to expand its premium pricing to include zinc and nickel, likely next year, and encourages producers to direct small volumes of sustainable metal to Metalshub to facilitate data sharing. The LME Insight website, currently offering CPAL's market commentary and premium prices for free, is expected to introduce a paywall to ensure its sustainability. This initiative, despite its current data-sharing challenges, aims to provide a more transparent system for valuing sustainable metals in the global market.
