Many of the changes announced Tuesday at Apple’s “Wonderlust” event involved the company’s quest to move all its products to becoming carbon neutral by the year 2030. One of those changes means Apple accessories, including watchbands and iPhone cases, will no longer use leather.

“Leather is a popular material for accessories, but it has a significant carbon footprint,” Lisa Jackson, Apple vice president of environment, policy and social initiatives, said during the event. “To reduce our impact, we will no longer use leather in any new Apple product, including watchbands, and that starts today.”

With leather gone from the watchband and other options, Apple is exploring more environmentally friendly materials. The company is calling one of those materials “FineWoven” and says it’s made of 68% postconsumer recycled content, giving it a significantly lower carbon footprint than leather, while offering a subtle luster and suedelike feel.

Apple will also use its FineWoven material for iPhone MagSafe cases and wallets, as well as the Magnetic Link and Modern Buckle Apple Watch bands.

The Apple Watch Series 9 also includes numerous technical changes, including faster performance, on-device Siri processing and a new means of interacting with the watch through a gesture called Double Tap.

And the Apple Watch Ultra, Apple’s high-end outdoors watch, will be available Sept. 22 and also includes Double Tap.
