Microsoft Corp. dramatically cut back investments in carbon removals in the first half of the year, as it ratchets up spending on artificial intelligence.
The company bought 8.55 million metric tons of carbon removal credits in the year through mid-July, which is about 80% less than it purchased over the same period in 2025, according to calculations by BloombergNEF. That puts Microsoft on track for its first retreat since 2023 from a market it entered in 2020.
