Prince William honored climate change innovators during a star-studded ceremony in Boston on Friday.
Britain's heir to the throne rewarded five entrepreneurs with o1 million each ($1.2 million) as part of his Earthshot Prize initiative to support efforts to save the planet from warming temperatures, reports AFP.
William's US visit was overshadowed by a racial conflict and his estranged brother Harry's Netflix series.
The couple's three-day trip to Boston focused on the environment, and they met President Joe Biden on Friday. This was Kate's first trip to the United States in eight years.
