Manhattan-sized basalt field in Brazil becomes live testbed for carbon removal

Microsoft is backing Terradot's groundbreaking carbon removal project in Brazil, where scientists are spreading finely milled basalt across 4,500 hectares of farmland to accelerate natural rock weathering that captures CO₂ from the atmosphere. The enhanced rock weathering process transforms carbon into dissolved bicarbonate stored in soils and groundwater, while Microsoft provides funding and technical expertise to verify the carbon removal through extensive monitoring systems tracking carbon's journey from soil to streams.
