The Prince and Princess of Wales are in Boston for the first time in eight years. William established the Earthshot Prize in 2020 to support entrepreneurs that are developing breakthrough climate solutions.

The name of the prize is a nod to President John F. Kennedy's 1962 "moonshot" speech.

The term has been used as a metaphor for goals that require a lot of money and brain power. The urgent nature of the climate challenge has led to some questioning whether a climate change "moonshot" could be used to avert catastrophe in the future.

A pool of nearly $60 million will be disbursed by the end of the decade thanks to the Earthshot Prize.

The Earthshot Prize, an independent charity that was recently broken off from William and Catherine's Royal Foundation, gives 1 million British pounds, or about $1.2 million, to each of five winners, one in each of the prize categories.
