Prince William will travel to Rio de Janeiro next month for the 2025 Earthshot Prize ceremony, but the Princess of Wales will reportedly remain in the UK with their children.

The event, set for November 5, marks the first time the Earthshot Prize will be hosted in South America and represents the halfway point in the initiative’s ten-year mission to tackle the planet’s most pressing environmental challenges.

Founded by the Prince of Wales in 2020, the Earthshot Prize honors five winners each year with £1 million grants to fund innovative environmental solutions.

Kate to Stay in Windsor with the Children

While Kate Middleton has long been a vocal supporter of the Earthshot mission, sources say her absence this year reflects a shared parenting decision rather than a retreat from royal duties.

According to reports, the couple maintain a personal rule ensuring that one parent is always home during term time to handle school routines for Prince George, Princess Charlotte, and Prince Louis.

This year’s ceremony follows a familiar pattern — Kate also missed last year’s event in Cape Town, opting to stay in Windsor, while her last in-person appearance at the awards was in Boston in 2022.
