Alt Carbon is a deeptech science and data company, building agri infrastructure for climate action. We aim to make South Asia a hub for Carbon Dioxide Removal (CDR) through technology pathways like Enhanced Rock Weathering.

We work with farmers and scientists in the Global South, to turn underutilized land into carbon sinks. Our flagship initiative, the Darjeeling Revival Project (DRP), is a first-of-its-kind effort to unite climate action with cultural and ecological restoration — by reviving degraded soils, restoring livelihoods, and rebuilding ecosystems.

We’re rooted in science, powered by community, and driven by the belief that revivals require ambitious people and audacious bets. Our mission is to remove 5 million metric tons of CO₂ by 2030.
