On Thursday, Microsoft revealed plans to acquire over 7 million tons of carbon credits from Chestnut Carbon.
This agreement, spanning 25 years, will empower Chestnut Carbon to undertake the reforestation of 60,000 acres across Arkansas, Louisiana, and Texas, as reported by Axios here. Recently, the tech giant has faced challenges in managing its carbon emissions due to a rapid increase in data center construction and operations fueled by AI advancements.
Microsoft reported a 29% spike in emissions since 2020, primarily driven by the AI and cloud computing boom, putting its 2030 target of sequestering more carbon than it emits at risk. In 2023, the organization documented producing 17.1 million tons of greenhouse gas emissions prior to offsets.
Carbon credits come with varied characteristics. Chestnut Carbon specializes in reforestation, where the firm facilitates tree planting and oversees the health of these new forests to ensure they thrive and remain protected. The company is currently managing eight projects in the Southeastern U.S. that were once farmland or pastures.
As trees grow, they naturally capture carbon, though not all forest-related carbon credits are of equal value. Credits from projects that plant fast-growing, non-native trees are often regarded as lower quality and typically fetch lower prices due to their limited biodiversity support and shorter lifespans. In contrast, projects that promote diverse, native plantings generally command a premium, given their associated ecological resilience over time.
Even the highest-quality carbon credits derived from afforestation, reforestation, and prevention of deforestation remain relatively inexpensive compared to other methods. Chestnut Carbon sold credits for $34 per ton last year, whereas direct air capture—which employs fans and chemical sorbents to extract CO2 from the atmosphere—costs between $600 and $1,000 per ton. Despite this cost disparity, Microsoft has also invested in carbon credits from direct air capture companies.
While nature-based carbon credits have significant benefits, they are not without flaws. Verra, a leading organization in nature-based carbon credits, faced scrutiny in 2023 from an in-depth investigation that suggested it had overstated the climate benefits of its initiatives. The fallout from the scandal resulted in the CEO’s resignation and prompted the sector to reevaluate its standards. Chestnut Carbon, which had previously counted on Verra for its carbon credit certifications, is now aligning with Gold Standard.
