Century Aluminium Company’s Jamalco operations have successfully achieved Aluminium Stewardship Initiative’s (ASI) Performance Certification with Provisional status. 

The achievement demonstrates another way the company upholds its core value of taking care of our people, communities and the planet.

 A joint venture between Century and Clarendon Alumina Production Ltd, Jamalco produces smelter-grade alumina for North American and European markets. With integrated operations spanning three bauxite mining sites, an alumina refinery, and its Rocky Point Port facility, Jamalco’s achievement marks another milestone under Century’s management. Notably, Jamalco is now the third Century Aluminium facility to achieve this prestigious certification, following the company’s Nordural facility in Grundartangi, Iceland—certified in 2020—and its headquarters office in Chicago, which was certified in 2021.

“We’re proud that Jamalco joins other Century Aluminium sites in voluntarily meeting higher standards from mine to metal, reinforcing our commitment to responsible operations and continuous improvement,” said Marvin Jackson, Jamalco’s managing director.

The ASI Certification programme was developed through an extensive multi-stakeholder consultation process and is the only comprehensive voluntary sustainability standard initiative for the aluminium value chain. The ASI Performance Standard V3 and ASI CoC Standard V2 were launched in May 2022 following a multi-year revision process. The ASI Performance Standard V3 defines 11 principles and 62 criteria under three sustainability pillars—Environment, Social, and Governance—to address pressing sustainability issues in the aluminium value chain, such as biodiversity, Indigenous Peoples’ rights, circularity, and greenhouse gas emissions.

The 2022 Standards and related documents underwent a minor update in 2023, accounting for editorial changes, correction of minor errors and general clarification, culminating in the release of Performance Standard V3.1 (2023) and Chain of Custody Standard V2.1 (2023).

The Provisional Certification serves as a strategic and flexible approach for aluminium sector actors to gain access to ASI’s sustainability standards framework, learn, and improve their practices over a defined period. It provides an opportunity for Members to commence their ASI Certification journey, while requiring a commitment to move towards Full Certification as soon as is practically possible.
