Earthshot Prize

By Callie Brauer, Conservation Working Group

In December 2022, Boston was honored to be the site of the Second Annual Earthshot Prize presentation. This is an award sponsored by Britain's Royal Foundation and is an annual prize given to five winners each year for contributions to improving the environment. Prize money of one million pounds (sterling) is awarded to the winner in each of five categories.

The Earthshot Prize began in 2021 and will continue to 2030. Britain's Prince and Princess of Wales are the leaders of the foundation and were in Boston to present the prizes.
