Prince William starts five-day Brazil environmental visit

Prince William was given the key to Rio de Janeiro as part of his visit

The Prince of Wales has touched down in Brazil for a five-day visit with a focus on the environment.

He started his first trip to the country in the city of Rio de Janeiro, taking in some of the incredible sights and getting the keys to the city from the mayor.

That's a traditional honour which is given to people, like royalty or sports stars, for their service and achievements.

But Prince William's main reason for visiting the country is to present the Earthshot Prize and deliver a speech at the climate meeting COP30.

The Earthshot Prize ceremony will be held on Wednesday at the Museum of Tomorrow in Rio de Janeiro - with the Prince William presenting the award to the winners.

He set up the prize in 2020 to celebrate people who have come up with big ideas to help tackle issues affecting the planet.

The people behind the winning ideas get £1 million to try and develop them further.

When he announced this year's nominees he said the people behind the "projects are heroes of our time" and said if we can support them "we can make the world cleaner, safer and full of opportunity".

After the Earthshot Prize ceremony, Prince William will travel to Belem in the Amazon rainforest to do a speech as part of COP30.

COP is a big meeting of a group of countries that agreed they would avoid behaviours that could lead to "dangerous climate change".

This will be the first time that the prince has travelled internationally for one of these meetings, with his father, King Charles making plenty of speeches at the events over the years.
