The $100M XPRIZE Carbon Removal competition was launched in 2021 to accelerate scalable, durable, and verifiable carbon dioxide removal solutions capable of operating at gigatonne scale. The prize challenged teams across technological pathways—nature-based, engineered, and hybrid approaches—to demonstrate performance, scalability, and long-term carbon durability.

Over four years, the competition convened a global ecosystem of innovators, researchers, students, and investors—helping define the next generation of carbon removal technologies and catalyzing rapid industry growth at a critical moment for climate action.
