In January last year, Gurgaon-based climate-tech company, Varaha ClimateAG Private Limited, struck the largest ever biochar carbon removal deals with Google and Microsoft. It was to sell 100,000 carbon removal credits each to the tech giants.
Biochar is a charcoal-like material made by burning biomass with low oxygen. This process locks away carbon that the biomass would otherwise release when it rots or burns. Applied to soil, biochar can increase fertility, by helping it hold water and nutrients.
