Google buys $100M in carbon credits from Indian startup using farm waste to make CO2-trapping biochar.

Google has agreed to purchase 100,000 carbon removal credits from Varaha, an Indian startup that converts agricultural waste into biochar, a charcoal-like substance that traps CO2 in the soil. This $100 million deal, one of the largest involving biochar, marks Google's entry into India’s carbon removal market and supports its goal of net-zero emissions by 2030. Varaha aims to use waste from smallholder farms to produce biochar, which can store CO2 for centuries.
