The Earthshot Prize revealed its winnersThe Colombian capital Bogota has been crowned one of this year’s Earthshot Prize winners, following the city’s ambitious – and successful – efforts to cut air pollution. These efforts have reportedly helped cut air pollution by 24% since 2018 – an achievement acknowledged by the Earthshot Prize. Launched in 2020 by Prince William, the award showcases solutions to environmental problems and helps their creators scale up by awarding them £1m each. The latest winners were announced at a star-studded event in Rio de Janeiro on Wednesday, ahead of the Cop30 climate conference. “Their work is the proof we need that progress is possible,” said Prince William.
