LME integrates CBAM-aligned emissions tracking into listed aluminium businesses — must submit data from June ’25

In a market increasingly ruled by emissions accountability, the LME has stepped forward with a landmark measure to align metals trading with the European Union’s Carbon Border Adjustment Mechanism (CBAM). As of June 15, 2025, all listed aluminium brands are required to submit verified emissions data through LMEpassport, the exchange’s digital certificate system.
At its core, the initiative is about harmonising with Brussels. The LME emissions reporting form asks producers to disclose Scope 1 and Scope 2 emissions, tailored precisely to match EU CBAM standards. Reporting is mandatory for brands under Primary Aluminium, Aluminium Alloy, and NASAAC. Prior to the recent development, on May 1 2024, the LME released a consultation on the proposed integration of the EU CBAM requirements into the LME Rulebook in respect of LME Primary Aluminium, Aluminium Alloy and North American Special Aluminium Alloy (NASAAC) to support the aluminium market.
