​Alt Carbon is an Indian company dedicated to removing carbon dioxide (CO₂) from the atmosphere. They use a method called enhanced rock weathering, which speeds up a natural process where CO₂ reacts with minerals in rocks, forming stable compounds that lock away the carbon permanently. By applying this technique to soil, they aim to sequester large amounts of CO₂ and also improve soil health. Alt Carbon collaborates with local agricultural communities, supporting them through their initiatives.
