The heir to the British throne, Prince William, has been in Singapore for the third annual Earthshot Prize awards ceremony. The event is meant to celebrate entrepreneurs and businesses who are working on solutions to climate change. This year’s winners include an Indian maker of solar-powered dryers, a soil carbon marketplace and groups that work to make electric car batteries cleaner, restore Andean forests and deter illegal fishing.

A glitzy ceremony took place at state-owned Media Corp on Tuesday, hosted by actors Cate Blanchett, Ted Lasso star Hannah Waddingham and Sterling K. Brown and featuring the bands One Republic and Bastille. Prince William wore a 10-year-old green suit by Alexander McQueen as he and other presenters walked a “green carpet.”

An entrepreneur who is creating an online marketplace for soil carbon credits, a company that is making electric car batteries more environmentally friendly and a global non-profit whose goal is to bolster law enforcement against the lucrative trade in illegal wildlife products were the three finalists for this year’s prize. The winner will receive a cash prize of S$300,000 (US$216,000), a trophy and a two-plus season exemption on the PGA Tour, as well as berths at some of its key events.

The second runner-up, an artist who has created a series of murals to highlight the impact of pollution on the natural world, won S$200,000 ($130,000) and a trophy. The third runner-up, who is designing a new platform to allow users to donate their used phones to developing countries, will receive S$100,000 ($69,000).

In a separate event, the Singapore prize, which was launched in 2014 by a group of private philanthropists, awarded its first book prize this year. The award carries a cash prize of S$3,000 (US$2,160) and an engraved trophy.

Professor Wang Gungwu, who chaired the panel that chose the winning book, said that Prof Miksic’s “confirmation of the history of Singapore through concrete archaeological evidence is a landmark.” The book also offers a fresh perspective on how tightly controlled the city-state has been through its turbulent past.

Several of the shortlisted books focus on Singapore’s rich cultural heritage and have shaped public discussion on the country’s past. Others have delved into the nature of Singapore’s state-sanctioned religions, such as Islam and Buddhism.

The winner of the literary prize, which carries a cash prize of S$3,000 and an engraved trophy, will be announced next month. The film winner will be announced later this year. The prizes are presented by the National Arts Council of Singapore. The council also confers a number of other accolades, including its most prestigious award, the President’s Medal, which has been bestowed to 132 artists since the foundation of the prize in 1995. It is the nation’s highest arts accolade. For more information, visit the NAC website. The council is supported by the government of Singapore. The NAC also supports a range of other creative and cultural initiatives in the city-state. In addition, it offers grants for professional development and training opportunities.
