After wrapping his visit on behalf of his Earthshot Prize to Cape Town, South Africa on Nov. 7, buzz is already starting as to where the fifth iteration of the Earthshot Prize Awards might take place.

Prince William wore white biodegradable sneakers as he walked the “green carpet” at his Earthshot Prize environmental awards ceremony in South Africa.

The royal honored the theme of the environmental awards with a pre-loved outfit and shoes from one of the eco-friendly finalists.

Emmy, Grammy, and Tony award-winning, American actor Billy Porter and celebrated South African television presenter Bonang Matheba have been tapped to host the fourth annual Earthshot Prize Awards in South Africa on November 6.

Prince William joined Robert Irwin in South Africa to promote conservation. The Prince of Wales and the Australian conservationist went on a nature walk on Tuesday, Nov. 5, on a trail on Signal Hill in Table Mountain National Park.

Britain's Prince William said he hope his multi-million dollar environmental prize would provide some much needed optimism for climate campaigners, saying the future was looking "pretty bleak" without the involvement of young people.

Prince William looked dapper as he arrived onto the green carpet for first ever Earthshot Prize awards in Africa. The Prince of Wales arrived in a grey suit jacket over a light blue shirt, paired with white trainers.
