Potential fixes to the world’s most persistent environmental problems are often little-known and underfunded. That’s why in 2020, Britain’s Prince William launched the Earthshot Prize to encourage approaches that deserve more attention and scale by 2030.

The initiative today announced five winners of the £1 million ($1.2 million) annual prize, now in its second year. The winning organizations are working to improve people’s health, cut pollution and reduce greenhouse gas emissions.
