Prince William and Princess Kate have called for a “better, more sustainable world” in a new social media post.

Just after King Charles formally began the process of stripping Prince Andrew of his titles and honours, the couple, both 43, shared the message on their Kensington Royal X account as part of ongoing promotion for the Earthshot Prize, William’s environmental initiative recognising global projects tackling climate change.

The post included a two-minute video highlighting finalists from Barbados, Bangladesh and the United States, describing how each is helping communities adapt to environmental challenges.

William and Kate wrote: “We envision a world that’s a better, more sustainable home for everyone. A world where greenhouse gas emissions are falling, and carbon-neutral economies help protect the most vulnerable. A world like this is within reach.”

It was the fifth consecutive day the Prince and Princess of Wales had posted Earthshot content, following videos released throughout the past week.

William, unveiling the Earthshot shortlist earlier this month, reflected on the urgency of the prize’s mission.

He said: “Back then, a decade felt a long time. George was seven, Charlotte five and Louis two; the thought of them in 2030 felt a lifetime away. But today, as we stand halfway through this critical decade, 2030 feels very real.”

Five winners will each receive £1 million ($2.3m) when the Earthshot Prize is awarded on November 5 at the Museum of Tomorrow in Rio de Janeiro, ahead of the COP30 UN climate summit.

The latest Earthshot message appeared less than a day after Buckingham Palace confirmed King Charles, 76, had ordered the removal of Andrew’s HRH style, titles and honours.

In a statement, the Palace said: “Prince Andrew will now be known as Andrew Mountbatten Windsor. These censures are deemed necessary, notwithstanding the fact that he continues to deny the allegations against him.”

It added: “Their Majesties wish to make clear that their thoughts and utmost sympathies have been, and will remain with, the victims and survivors of any and all forms of abuse.”

Andrew, 65, is expected to vacate Royal Lodge and live privately under the King’s care at Sandringham Estate.

Royal sources told the Daily Mail he could receive around £500,000 as part of the early termination of his lease agreement.

Meanwhile, Republic, the anti-monarchy campaign group, said it had instructed lawyers to explore a private prosecution against Andrew over allegations relating to his friendship with Jeffrey Epstein.
