Apple improves global footprint - especially thanks to aluminium

10 August 2020

The American technology company Apple has been able to improve its CO2 balance by 35 percent in 2019. This has been achieved through a strong focus on energy efficiency, low-carbon production and the switch to one hundred percent renewable electricity. And aluminium has also played a key role in this success.

By using recycled aluminium as a material basis in production, carbon emissions have been reduced by 4.3 million tonnes. For example, Apple reduced the amount of aluminium used in the manufacture of the Apple Watch 5 series by 50 per cent by using a new extrusion process. The aluminium used in this process is derived entirely from waste generated in the manufacture of other Apple products. With this increased efficiency and the use of recycled aluminium, CO2 emissions from the production of aluminium enclosures have been reduced by 25 per cent.

Aluminium is a key material for most products. That's why Apple established a joint venture between aluminium manufacturers Alcoa Corporation and Rio Tinto Aluminum in 2018 with the goal of patenting a technology that significantly reduces greenhouse gas emissions during the smelting process. The material obtained in this way is currently used for the 16-inch MacBook Pro.

Apple's successful environmental record once again underscores the importance of aluminium as the material with which a climate-friendly future is made today.
