Rio Tinto’s existing Chain of Custody certification (ASI Certificate #4) for its operations in Québec and its bauxite mine in Australia has been extended to include the BC Works smelter and Kemano Power Operations in Kitimat, British Columbia.

The ASI CoC Standard sets out requirements for the creation of a Chain of Custody for material that is produced and processed through the value chain into diverse downstream sectors. The implementation of ASI’s CoC Standard links verified practices at successive steps of the supply chain – certified under the ASI Performance Standard – to the products produced by ASI Certified Entities. Rio Tinto’s Certification includes bauxite mining, alumina refining, aluminium smelting and remelting, and casthouse operations, thus enabling the production of ASI Certified Aluminium.

The ASI Certification program was developed through an extensive multi-stakeholder consultation process and is the only comprehensive voluntary sustainability standard initiative for the aluminium value chain. The independent, third-party audits of the Kitimat operations were carried out by BNQ.

Rio Tinto Aluminium vice president sales and marketing and ASI Board member Tolga Egrilmezer said “This certification continues Rio Tinto’s leadership on responsible production. It increases the availability of ASI certified aluminium in a range of markets, giving customers the ability to offer end consumers products made with aluminium that meets the highest sustainability standards.”

ASI chief executive officer Fiona Solomon said “We applaud Rio Tinto for their commitment to ASI’s mission since joining as a founding member, and for continuing to extend the reach of their ASI certified operations. This successful Chain of Custody certification demonstrates ASI’s potential to create impact through voluntary uptake of its program. We are seeing the positive upstream examples like this one now extending into downstream aluminium use sectors such as automotive, construction and packaging, and this is very encouraging.”
