The iPhone maker has been working to reduce its use of the carbon-intensive metal.
Apple announced on Thursday that it will purchase its first industrial-size batch of carbon-free aluminum tio use in its low-cost iPhone SE, as it ramps up efforts to reduce the carbon footprint of the metal it heavily uses in product casings.
The size or cost of the purchase were not disclosed.
The iPhone maker has taken steps to reduce its use of the carbon-intensive metal, which emits direct greenhouse gases during the smelting process and has sparked consumer, activist, and investor outrage due to its environmental impact.
Apple first purchased a smaller batch of the lab-made metal in 2019 from Elysis, a Montreal-based joint venture between two of the world’s largest aluminum suppliers, Alcoa and Rio Tinto. It had used metal in its 16-inch MacBook Pro.
Elysis had hoped to commercialize its technology, which uses a ceramic anode to produce aluminum and emits only oxygen, by 2024.
