ASI Chain of Custody Material along the value chain shown in IAI Global Mass Flow model

M&E Insights, January 2021

ASI has published 2019 data for ASI Chain of Custody flows, visualized in the context of aluminium global supply and demand for that year. It is the result of a valuable and ongoing collaboration with the International Aluminium Institute (IAI) and was supported by an ISEAL Impulse Grant.

ASI Material is produced, transformed and received by Entities along the aluminium value chain that are each Certified against both the ASI Performance Standard and ASI Chain of Custody (CoC) Standard.

As part of ASI’s Monitoring & Evaluation program, CoC Certified Entities are required to annually report on CoC material inputs and outputs. By the end of 2019, there were 13 dual-Certified Entities, enabling the first data collection cycle to commence in 2020. Eleven of these Entities were CoC Certified during the course of 2019, meaning their ASI production represents only part of a year.

The data is visualized in a Sankey diagram developed by IAI, and the green stripe shows ASI Material flows in the context of global supply and demand:

The 2019 data shows ASI Material flows are highest so far from bauxite mining, with each subsequent supply chain stage reducing in volume. This is to be expected, as available supply must be first built to enable the subsequent supply chain stage to source.

Data from each reporting year will be added annually, enabling year-on-year growth to be shown. At the end of 2020, there were 28 dual-Certified Entities, more than double the number in 2019. A measurable increase in the flow of ASI Material is thus expected to be shown in the next reporting cycle.

With this first set of published data, ASI demonstrates a commitment to transparency and whole of supply chain uptake and impact. We sincerely thank IAI for their collaboration and support, and all CoC Certified Entities for their contributions to this first reporting cycle.

We look forward to building on these important beginnings and invite all interested supply chain actors and stakeholders to contribute to this momentum!
