Microsoft in record deal for soil carbon credits as data centres surge

Microsoft has agreed with Indigo Carbon to buy a record 2.85 million soil ‍carbon credits linked to regenerative agriculture in the United States, as the tech giant aims to become “carbon ⁠negative” by 2030 despite surging emissions linked to AI.

While Microsoft – the world’s biggest buyer of carbon removal credits – did not disclose the cost of the 12-year tie-up, a person with knowledge of the deal said ‌it falls within ‌the historic range of $60 to $80 a ton for Indigo Carbon’s credits, which would value the deal at between $171 million and $228 ‌million.
