  • Five winners, one in each category, will receive £1 million to scale solutions in Revive Our Oceans, Fix Our Climate, Build a Waste‑Free World, Protect and Restore Nature, and Clean Our Air.
  • This year’s shortlist was selected from roughly 2,500 nominations across 72 countries, marking the initiative’s midpoint on its 2020–2030 timeline.
