Prince William awards Earthshot prizes as US visit wraps up

Boston: Prince William honored climate change innovators during a star-studded ceremony in Boston Friday at the culmination of a US trip overshadowed by a race row and estranged brother Harry´s Netflix series.

Britain´s heir to the throne rewarded five entrepreneurs with £1 million each ($1.2 million) as part of his Earthshot Prize initiative to support efforts to save the planet from warming temperatures.

Annie Lennox and sisters Chloe x Halle were among singers to perform at Boston´s MGM Music Hall. Actor Rami Malek and ex-footballer David Beckham presented awards.

British naturalist and television presenter David Attenborough and actress Cate Blanchett were among the judges.

Winners included a female-founded start-up providing cleaner-burning stoves to women in Kenya and a British company that crafts biodegradable packaging from marine plants.

"I believe that the Earthshot solutions you have seen this evening prove we can overcome our planet´s greatest challenges. And by supporting and scaling them we can change our future," William told the audience.

The ceremony, now in its second year, was trailed by royal insiders as William´s "Superbowl moment" and came at the end of his and wife Kate´s first visit to the United States in eight years.

The couple´s three-day trip to Boston focused on the environment, as they discussed rising sea levels with local officials and toured a laboratory specializing in green technologies. William briefly met President Joe Biden Friday.

The trip started Wednesday under a cloud after William´s godmother Susan Hussey apologized and quit the royal household for repeatedly asking a Black British woman where she was "really" from during a reception at Buckingham Palace the day before.

A spokesman for the royal couple told reporters in Boston that William believed it was right that Hussey, 83, had stood down.

Then on Thursday, Netflix unveiled a trailer for its six-part docuseries in which Harry and wife Meghan Markle lift the lid on their lives in the royal family, which they quit in 2020.

Harry and Meghan, a mixed-race former television actress, cited racism in the royal household as one of the reasons for their acrimonious departure and move to California almost three years ago.
