Aluminium producer Hydro now supplies sustainable aluminium for the battery housing of Audi's first fully electric model, adding to its green credentials.


The supply chain of the Audi e-tron is becoming more sustainable: The aluminium producer Hydro now supplies sustainable aluminuim for the battery housing of the first fully electric model of the company. The material is processed and manufactured along the entire process chain in an environmentally-friendly manner and under socially acceptable working conditions.

The Audi e-tron is produced in a carbon nautral plant in Brussels 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 aluminum components in October 2018. This means that the aluminum 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% 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.

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 aluminum. 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.
