ASI certifies Rio Tinto against ASI Performance Standard and Chain of Custody Standard certifications

Rio Tinto has successfully expanded their certification scope to the ASI Performance Standard and Chain of Custody Standard to include several of its facilities in Australia and New Zealand. Their ASI Certifications now additionally cover the Amrun and Weipa bauxite mines, Yarwun alumina refinery, and the Bell Bay and NZAS aluminium smelters.

Aluminium Stewardship Initiative (ASI) today announced that Rio Tinto has successfully extended their existing certifications to the ASI Performance Standard and Chain of Custody Standard to additionally include two bauxite mines, an alumina refinery, two smelters and associated casthouses.

The ASI Performance Standard defines environmental, social and governance principles and criteria, with the aim to address sustainability issues in the aluminium value chain.
It sets out 59 criteria under the three sustainability pillars of Governance, Environment and Social, which address key issues such as biodiversity, Indigenous Peoples rights, and greenhouse gas emissions.

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.

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 audit of Rio Tinto’s Performance Standard Certification scope change was carried out by ERM Certification and Verification Services, while the independent, third-party audit of Rio Tinto’s CoC Certification scope change was carried out by BNQ.

ASI Chief Executive Officer, Fiona Solomon, said “Having a responsible supply chain means not just low carbon emissions in production, but meeting the highest standards from material stewardship to human rights. We applaud Rio Tinto’s ongoing commitment to encouraging the uptake of ASI’s standards across the aluminium and manufacturing supply chain.”

Rio Tinto Aluminium chief executive, Alf Barrios, said “This certification enhances Rio Tinto’s offering of independently certified, responsibly produced aluminium to customers in markets around the world. It continues our leadership on responsible production, so that customers can meet the growing demand from consumers for sustainably sourced products.”
