Apple:

Aluminum giants Alcoa Corporation and Rio Tinto Aluminum today announced a joint venture to commercialize patented technology that eliminates direct greenhouse gas emissions from the traditional smelting process, a key step in aluminum production. This is a revolutionary advancement in the manufacturing of one of the world’s most widely used metals.

As part of Apple’s commitment to reducing the environmental impact of its products through innovation, the company helped accelerate the development of this technology. And Apple has partnered with both aluminum companies, and the Governments of Canada and Quebec, to collectively invest a combined $144 million to future research and development.

And:

[Apple Engineers] Lynch, Yurko and Sassaman learned that Alcoa had designed a completely new process that replaces that carbon with an advanced conductive material, and instead of carbon dioxide, it releases oxygen. The potential environmental impact was huge, and to help realize it quickly, Alcoa needed a partner.

Apple once again demonstrates its commitment to do what it can to minimize the environmental impact of its products.
