A Stanford‑spawned startup, Terradot, is spreading crushed volcanic rock across Brazilian cropland so rainfall turns CO2 into bicarbonate that washes to the ocean for long‑term storage. It has applied 100,000 tons of rock over 4,500 hectares, signed contracts to remove ~300,000 tons of CO2, and expects its first verified removal credits this year.
— Commercial‑scale enhanced weathering could reshape carbon markets and climate policy by adding a land‑based removal option with tough measurement and governance challenges.
