The Duchess of Cambridge looked stunning in a bold green coat and half-sleeve knit for a visit to London's Kew Gardens.

The duchess' bold green overcoat is by Erdem and she paired it with a matching light jumper, black wide-leg trousers, and coordinating pointed-toe pumps.

The Duchess was joined by the Duke of Cambridge to take part in an event with The Heathland School as part of the Generation Earthshot project. Prince William opted for a navy suit and a light-blue oxford shirt for the royal outing.

The Duke and Duchess worked with the school students to brainstorm "big, bold ideas to repair the planet and to help spark a lasting enthusiasm for the natural world."

The royal couple were joined by the mayor of London, Sadiq Khan, for the garden visit, while explorer and naturalist Steve Backshall MBE and Olympian Helen Glover got involved in activities with the students.

Generation Earthshot is an educational initiative inspired by William's Earthshot Prize, a new annual effort to help combat climate change and environmental disasters over the next decade.

"We know that young children already identify the climate as one of their biggest worries, and Generation Earthshot aims to educate and encourage them that together we can find the answers. Children can be uniquely creative and I can’t wait to see some of the ideas that are shared with us," Prince William said during the visit.

The first Earthshot Prize Awards will be held on 17 October at Alexandra Palace in London, and will be broadcast to a global audience via the BBC and Discovery+.

Both Prince William and Kate, Duchess of Cambridge will be present for the ceremony, which will celebrate the 15 incredible finalists from around the world and award the first five winners of The Earthshot Prize.
