XPRIZE Carbon Removal, funded by Elon Musk and the Musk Foundation, aims to find solutions that fight climate change and rebalance Earth’s carbon cycle. This four-year global competition invites innovators and teams from anywhere on the planet to create and demonstrate solutions that can pull carbon dioxide directly from the atmosphere or oceans. Any carbon negative solution is eligible: nature-based, direct air capture, oceans, mineralization, etc. The competition will last for 4 years through Earth Day 2025. After one year of competition the judges will review all submissions and award up to 15 Milestone Prizes of $1 million each. After 4 years, judges will select the winners: a single Grand Prize Winner (US$50 million) and 3 runners up (US$30 million). Registration for the prize will remain open through 01 December 2023.
