Apple has made some pretty big environmental claims over the years, and one of the more eyebrow-raising ones centered on select models of its Apple Watch Series 9.

Apple said it was able to bring a redesigned blood oxygen feature to its devices after a recent U.S. customs ruling.

Apple can no longer advertise its Apple Watch as a "CO2-neutral product" in Germany, following a court ruling on Tuesday that upheld a complaint from environmentalists, finding that the U.S. tech company had misled consumers.
