The material is processed and manufactured along the entire value chain in an environmentally conscious manner and under socially acceptable working conditions. This has been confirmed by the Aluminium Stewardship Initiative (ASI) with a “chain of custody” certificate. The ASI already awarded Audi a certificate for the sustainable assembly of these aluminium components in October 2018. This means that the aluminium sheets processed in the battery housing of the Audi e-tron are now demonstrably produced in a responsible manner along the entire value chain, from the extraction of the bauxite raw material to the end product.

The two partners pursue sustainability as an important goal in their corporate strategy and together want to reduce CO2 emissions from the use of aluminium. By 2025, Audi aims to reduce the CO2 footprint of its products throughout their lifecycle by about 30 percent compared with 2015. There is great potential in the use of sustainable and responsibly extracted resources.

Certification by the ASI is the result of various workshops in which Audi and Hydro exchanged their expertise on effective measures for CO2 reduction.

“We want to offer our customers completely CO2‑neutral mobility by 2050 at the latest. To do that, we need a sustainable supply chain,” says Dr. Bernd Martens, Audi Board of Management Member for Procurement and IT. “We therefore seek dialogue with our partners and, together with them, want to significantly reduce CO2 emissions along the entire value chain.”

In late 2018, Audi started a CO2 program in procurement and since then has already carried out more than 20 CO2 workshops with aluminium suppliers. Hydro is one of the first aluminium producers to offer sustainable aluminium sheet that is certified by the ASI.

“We are very proud to supply ASI-certified metal, especially for the Audi e‑tron, one of Audi’s flagships. We are constantly working on reducing our impact and that of our customers on the environment,” says Einar Glomnes, Executive Vice President at Hydro. “This is an important milestone in our strategy of helping our customers to document the fact that they offer aluminium products that are procured and produced responsibly along the entire value chain.”

ASI encompasses environmentally, socially and economically ethical criteria that apply along the entire value chain, from the extraction of the raw material bauxite to the processing, production and recycling of aluminium. For example, it is assessed whether a company uses the material in a resource-conserving manner, prepares holistic lifecycle analyses and considers the subsequent repair and recyclability of its products in the design phase.
