On Earth Day (April 23, 2025), the winning teams of the XPRIZE Carbon Removal Competition were announced at the TIME100 Summit in New York City. Indian-African company Mati Carbon won the $50 million grand prize for its enhanced rock weathering program. Five runners-up — NetZero, Vaulted Deep, UNDO Carbon, Planetary, and Project Hajar — received a share of the $100 million prize sponsored by the Musk Foundation.

Mati, which collaborates with Remineralize the Earth (RTE) on projects in the Global South, was selected as the winner of the XPRIZE Carbon Removal thanks to its remineralization project, an often overlooked strategy of ERW (Enhanced Rock Weathering). While ERW focuses on the carbon removal abilities of rock dust, remineralization considers the broader impacts of rock dust spreading on agricultural land, including improved outcomes for farmers through increased crop yields and increased nutrient density.
