Progress toward Apple 2030

Apple 2030 is our goal to be carbon‑neutral across our value chain. We design our products to be less carbon intensive by prioritizing the use of recycled and renewable content and low‑carbon materials while focusing on the energy efficiency of our software and hardware.

See Apple’s commitment

Materials

Apple Watch Series 12 with aluminum and titanium cases are made with 40% recycled content,20 including:

  • 100% recycled aluminum in the aluminum case
  • 100% recycled cobalt in the battery
  • 100% recycled copper wire and recycled tungsten in the Taptic Engine
  • 100% recycled gold plating and tin solder in all Apple‑designed printed circuit boards
  • 95% recycled lithium in the battery
  • 100% recycled titanium in the titanium case

Packaging

100% fiber‑based packaging21

Energy

  • 100% of manufacturing electricity for Apple Watch Series 12 with aluminum and titanium cases is sourced from renewable electricity22
  • 100% of expected customer energy use matched with renewable electricity for Apple Watch Series 12 with aluminum and titanium cases22,23

Waste

No established final assembly sites generate waste sent to landfill as part of Apple’s Zero Waste Program24

Smarter chemistry25

All of the materials used in Apple products, accessories, and packaging are covered by the requirements of our Regulated Substances Specification, which was one of the first in industry to restrict the use of key substances of concern. See the latest Environmental Progress Report to understand Apple’s recent efforts in phasing out these chemistries.
