The Prince of Wales has declared the “urgent optimism” at the core of his environmental Earthshot Prize “unstoppable”, following the announcement of the 2025 finalists. Prince William established the prize to recognise and scale up ideas aimed at repairing the planet, with five winning finalists each receiving £1 million to advance their concepts.
Winners will be unveiled at the fifth Earthshot Prize awards in Rio de Janeiro, Brazil, on Wednesday, 5 November. The prize champions solutions from diverse geographies, sectors, and developmental stages, all dedicated to solving the planet’s greatest challenges. The event in 2025 marks the halfway point in the Earthshot decade, with William pointing out that at the time of its launch in 2020, scientists made clear significant changes had to be made by 2030.
In a video message posted on social media, William, who will be travelling to Brazil in November, 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.” He added: “The Earthshot Prize was founded because this decade matters. 2030 is a threshold by which future generations will judge us; it is the point at which our actions, or lack of them, will have shaped forever the trajectory of our planet.”
William said he is “deeply proud” of what the Earthshot Prize has done in its first five years and is “enormously excited” for the next five. “Not just for the new finalists we’ll welcome into our network, but to see the continued impact of our 60 existing finalists,” he said. “Together, they are moving us towards achieving vital global goals that will improve and secure lives and livelihoods for all of us – goals such as protecting 30 per cent of our land and sea by 2030.”
Among the 15 finalists is a British company, Matter, headquartered in Bristol, whose simple washing machine filters remove the greatest cause of microplastics in the ocean. Adam Root, chief executive and founder of Matter, said: “Being a finalist for the Earthshot Prize and representing Matter at the awards ceremony in Rio is like winning an Olympic gold medal in innovation.” Actress Cate Blanchett, an Earthshot Prize council member, said: “Five years with the Earthshot Prize has shown me that optimism isn’t abstract – it’s something made real by people bold enough to act now.”
