Lithos Carbon accelerates Earth’s natural carbon cycle via enhanced rock weathering on farms. By spreading organic-grade basalt, they permanently remove CO₂ while improving crop yields and soil health—helping decarbonize a food system responsible for ~25% of global emissions. Lithos selects superfine, low-footprint basalt and uses a cost-effective MRV framework—developed with Yale and Georgia Tech—to precisely measure, report, and verify captured carbon.
