Microsoft plans to buy 3.5M carbon credits, estimated to be worth ~$200M, from Re.green over 25 years to restore parts of Brazil's Amazon and Atlantic forests

Context & Ripple Effects
Microsoft’s proposed 25-year Re.green purchase extends its 2030 carbon-negative commitment into a long-duration restoration contract. It follows the company’s earlier 500,000-credit agreement with Occidental’s 1PointFive, showing that it is using multiple carbon-credit approaches rather than a single supplier or project type.
The deal also sits against pressure created by Microsoft’s rising emissions, which were reported after its climate pledge. Its later multimillion-credit soil-carbon purchase from Indigo Carbon underscores how large, multi-year procurement has become central to the company’s climate strategy.
First-order effects
- Re.green gains a large, long-term buyer for credits tied to restoration in Brazil’s Amazon and Atlantic forests, while Microsoft secures 3.5 million credits toward its climate commitments.
- Microsoft commits an estimated $200 million over 25 years, making the quality, delivery, and durability of the underlying restoration projects material to its carbon-accounting plans.
Second-order effects
- Other credit developers gain evidence that large corporate buyers may support long-duration nature-restoration contracts, but they will need to compete on project credibility and ability to deliver credits over time.
- Microsoft’s use of restoration credits alongside credits from a US carbon-capture project broadens demand across carbon-removal pathways, potentially increasing scrutiny of how different credit types are assessed.
Third-order effects
- If large buyers continue to sign diversified, multi-decade offtakes, voluntary carbon markets could shift from intermittent credit purchases toward contracted project finance tied to delivery performance.
- The pattern raises the strategic importance of consistent standards for permanence and verification: corporate climate claims will increasingly depend on whether long-lived credits perform as contracted.
The trend: Corporate climate procurement is evolving into diversified, long-term offtake for carbon-removal and restoration projects, with buyers seeking supply across distinct credit types.
