Microsoft Buys India’s Rock Carbon Credits

Microsoft just pulled off a major climate play by securing a three-year deal to buy nearly 37,000 tons of carbon removal credits from India’s Alt Carbon — its first enhanced-rock weathering purchase in Asia. The credits, sourced from a Darjeeling farm project, will be delivered by 2029 after a year-long vetting process that included rigorous scientific oversight. This move counters rumors of Microsoft scaling back on carbon credits, reaffirming its commitment while refining its strategy. Alt Carbon, a startup founded last year, uses crushed basalt rocks spread on farmland to naturally lock away CO2 — a method gaining serious traction as the carbon removal market struggles with credibility. Already a global leader in verified enhanced-rock weathering credits, Alt Carbon leverages the Isometric registry for precision tracking and has attracted big-name buyers like Google and Shopify, plus $12 million in seed funding to back its lab-built verification standards.
