A collection of Rio Tinto operations in Australia and Canada – spanning bauxite mining, alumina refining, aluminium smelting through to casthouses – have been successfully granted ASI’s first Chain of Custody (CoC) Certification.  The announcement of the world’s first ASI CoC Certification means that ASI Aluminium will be available on the market, only six months after the launch of ASI’s voluntary standards program.

ASI developed Chain of Custody (CoC) Certification to support businesses in the aluminium value chain that wish to provide their customers and stakeholders with independent assurance for responsible production and sourcing of aluminium.

ASI Aluminium is tracked by Certified companies under a mass balance model along the production process.  A Certified casthouse is the first point in the chain that can issue ASI Aluminium, delivering a new choice for downstream customers that are looking to source responsibly produced aluminium.

The inaugural ASI CoC Certification covers Rio Tinto’s bauxite mining in Gove, Australia, and primary metal production from selected facilities in the Province of Quebec, Canada.  A pre-requisite for CoC Certification is that facilities also achieve Certification against the ASI Performance Standard, which Rio Tinto successfully achieved for these operations in April 2018 in another world first.  The independent, third-party audits in Australia and Canada were carried out by BNQ (Bureau de Normalisation du Québec).

Fiona Solomon, Chief Executive Officer at ASI said: “ASI’s overall objective with its Chain of Custody Standard is to stimulate supply and demand for ASI Aluminium through the global value chain.  By implementing ASI’s innovative Certification program, encompassing both performance and chain of custody, companies are now able to provide independent assurance of responsible production, sourcing and stewardship of aluminium.”

“We applaud Rio Tinto for their commitment to ASI’s mission since joining as a founding member, and for being the first to achieve ASI Certification for both ASI Standards.  This successful CoC Certification demonstrates ASI’s potential to create impact through voluntary uptake of its program.  We look forward to the positive example being set by upstream producers, like Rio Tinto, extending into downstream aluminium use sectors such as automotive, construction and packaging.”

Rio Tinto Aluminium chief executive Alf Barrios said “Achieving this Certification demonstrates Rio Tinto commitment to the highest international production standards and offers customers the ability to provide end consumers with the confidence that the aluminium in their products has been responsibly produced.

“Aluminium has a key role to play as a material of choice to reduce carbon and increase recycling across a wide range of end products from food packaging to buildings, planes, cars, mobile phones and computers.”

Rio Tinto has led the establishment of responsible production certification for the aluminium industry as a founding member of the ASI, working alongside customers and a broad range of stakeholders.

Rio Tinto Aluminium vice president sales and marketing and ASI Board member Tolga Egrilmezer said “We see certified sustainable aluminium as a point of differentiation for Rio Tinto as customers become increasingly interested in ensuring that metals have been responsibly produced. The ASI Certification will enable us to generate value for Rio Tinto and our customers because we believe there will be a fundamental shift in demand for these products.”
