“One of my passions is exploring ways that we can protect and promote the natural world—something I have in common with His Majesty,” the Oscar-winning actress said, adding that protecting the planet and encouraging young people to learn about the “beautiful” countryside was something that was “deeply important” to her.

“I am so thrilled to become an ambassador for The King’s Foundation, particularly as the charity celebrates its 35th anniversary this year,” Kate said of the organization formerly known as The Prince’s Foundation before Charles took the throne in 2022.

“The King’s Foundation does such fantastic work to prioritize and protect nature and our wonderful planet, in particular championing field to form farming, as well as getting young people outdoors and learning about our beautiful countryside and how we can all play a part in protecting its future—all things that are deeply important to me and to so many of us,” Winslet continued.

Winslet added that “it’s been fascinating learning about what the foundation does over these past few months, and I am really looking forward to collaborating with the other ambassadors so we can discuss ways in which we can collectively make a positive difference.”

The organization was founded by Charles in 1990 with the mission of advocating “for the change His Majesty wants to see in the world.”

“We look forward to working with Kate to promote our work over many years to come,” Murrin continued.
