Alt Carbon scores $12M seed to scale carbon removal in India

Alt Carbon, a climate tech startup founded by siblings Shrey and Sparsh Agarwal, transformed their struggling family tea estate in West Bengal into an innovative project using waste basalt rock dust to combat climate change. The company's pilot project aims to remove 5 million tons of carbon by 2030 through a 500-acre site, with plans to expand to 500,000 hectares and deliver its first carbon credits soon. Secured investments from notable organizations like Stripe and Meta have positioned them strategically for growth, while their proprietary mix, Hari Maati, targets farmers to enhance soil fertility and crop yields, ensuring community buy-in and scalability.
