Enhanced Rock Weathering Carbon Credits
Enhanced rock weathering accelerates a natural process: silicate rocks such as basalt are crushed and spread on farmland, where they react with CO₂ and rainwater to form stable bicarbonates that eventually wash into the ocean.
The result is permanent carbon removal with agricultural co-benefits: the rock dust can improve soil pH and release nutrients. Measurement methodologies are maturing quickly, and several registries now accredit weathering projects.
