Apple Buys First Carbon-Free Aluminum from Rio-Alcoa Venture

Apple Inc. is taking delivery this month of the first batch of carbon-free aluminum produced by a Montreal-based venture, helping move the iPhone maker closer to its greenhouse-gas reduction goal.

Elysis, a joint venture between Rio Tinto Group and Alcoa Corp. backed by Apple, uses new technology that emits pure oxygen when producing aluminum. Apple has said in an environment report that 80% of its emissions from an iPhone 8 came during the production phase. The metal is also used in iPads, Macs and Apple watches.
