A project to restore tropical forests and a global ocean treaty initiative are among the winners of this year's Earthshot Prize.
The winners, named at an awards ceremony in Brazil on Wednesday, will each be given £1m to scale up their projects to repair the climate.
The Prince of Wales, who founded the global environmental award in 2020, said the winners were an inspiration and proof that progress is possible.
Brazilian football legend Cafu, Olympian Rebeca Andrade, and former Formula 1 driver Sebastian Vettel were among the presenters, while pop stars Kylie Minogue and Shawn Mendes performed at the ceremony in Rio de Janeiro's Museum of Tomorrow.
UK Prime Minister Sir Keir Starmer, Energy Secretary Ed Miliband, and London Mayor Sir Sadiq Khan were also in attendance.
Prince William, who is the president of the prize, told those gathered at the ceremony that he had founded the award with the aim of making this the decade in which we transformed our world for the better.
There are five Earthshots, or goals, for which an award is given: Protect and Restore Nature; Clean Our Air; Revive Our Oceans; Build a Waste-Free World; and Fix Our Climate.
This year, nearly 2,500 nominees were submitted from 72 countries, and from these, 15 finalists were selected, from which the five winners were chosen.
