AUDI AG is the first automobile maker to be awarded the Chain of Custody certificate of the Aluminium Stewardship Initiative (ASI). This certifies that Audi can comply with the materials flow chain for sustainably produced aluminum in accordance with the ASI standard and can also input correspondingly certified material to the Aluminum Closed Loop with its suppliers. In this way, the level of sustainability attested by the ASI is completely maintained, not only for components of car making but also for the process scrap from Audi press plants that is retained in the loop.
