The Duke of Cambridge has urged the world to “stop talking” and move towards “action” during an appearance on a climate change podcast.

William launched his £50 million Earthshot Prize earlier this month, which aims to recognise solutions, ideas and technologies that “repair the planet”.

He was joined by fellow Earthshot council member Christiana Figueres on the Outrage + Optimism podcast which she co-hosts.

Speaking about his motivation for launching the ambitious environmental prize, the duke said: “The science is out there and is irrefutable. We have the data. So let’s stop talking about it and let’s actually provide the action.

“I think that’s what’s going to be really needed over these next ten years.”

The Earthshot Prize takes its inspiration from the Apollo Moon landings, nicknamed Moonshot, which helped advance mankind’s technological achievements

The prize features five categories – or Earthshots – which organisers say, if achieved by 2030, would improve life for all.

Every year from 2021 until the end of the decade, winners in the five Earthshots will each receive £1 million after being picked by a judging panel of William and other leading figures including Sir David Attenborough and Shakira.

Outrage + Optimism is a weekly podcast which has featured guests from climate activist Greta Thunberg to US politician John Kerry.

It is co-hosted by ex-UN climate chief Ms Figueres, political strategist Tom Rivett-Carnac and Paul Dickinson, the founder of environmental charity CDP.

Speaking about the podcast episode, which will be available on Friday, Ms Figueres said: “The Earthshot Prize will not only deliver important innovations to make progress on the most pressing issues of our time, but it will inspire a generation so that many more change-makers will no doubt emerge.

“Tackling climate change is not a far-off challenge – we have the technologies, tools and resources to achieve a halving of emissions this decade, as science shows is necessary.”
