Prince William is on the move again—and this time it’s to a special place close to his heart and the heart of wife Kate Middleton.

In a recent statement posted to Instagram Stories and signed by Prince William himself, the royal couple revealed that William will be heading to South Africa this week to celebrate The Earthshot Prize, a global environmental award that’s rewarded to a handful of winners each year to further advancements in environmentalism. Each winner receives a grant of £1 million (almost $1.3 million) to continue their environmental work, and The Royal Foundation has been a part of this great cause since its inception in 2021.
