Chestnut Carbon

Afforestation-based carbon offsets with monitored forests

Overview

Chestnut Carbon turns marginal land into biodiverse forests in the United States to act as carbon sinks. It partners with local foresters, nurseries, and communities to design and implement afforestation projects tailored to local conditions, then uses advanced technology to monitor forest growth and how much carbon is stored. The projects are verified by Gold Standard certification and FSC approval, ensuring transparency and high standards, and the resulting carbon removal credits are sold to help clients offset their footprint. Chestnut Carbon stands out by combining site-specific forest restoration with strict, third-party verification and data-driven tracking, plus clear co-benefits for wildlife, air and water quality, and local economies. Its goal is to restore more than 100,000 acres and remove 100 million tons of carbon from the atmosphere by 2030.

Simplify's Take

What believers are saying

  • RBC bought Chestnut IFM credits in September 2026, widening blue-chip demand beyond Microsoft.
  • Sol Systems renewed Chestnut purchases in August 2026, showing repeat commercial traction.

What critics are saying

  • Microsoft publicly adjusted carbon procurement pace in 2026, exposing Chestnut to buyer concentration.
  • Chestnut's credits face long-dated delivery risk through 2030, while forestry execution spans decades.
  • If carbon buyers reject nature-based offsets, Chestnut's core project-finance model breaks.

What makes Chestnut Carbon unique

  • Chestnut became Microsoft's largest U.S. nature-based carbon removal partner in January 2025.
  • Chestnut launched Chestnut Nature Works on September 22, 2026, targeting infrastructure environmental execution.
  • Chestnut's 2026 FSC verification for biodiversity impacts strengthens credibility beyond standard carbon accounting.

Chestnut launches new business to align data centre growth with community and environmental benefits

Chestnut has launched Chestnut Nature Works (CNW), a new business helping developers, utilities, and communities build environmental and community foundations for data centre and industrial projects across the United States. CNW addresses local concerns about water availability, environmental impacts, and community benefits by delivering measurable outcomes including watershed restoration, protected land, and community assets. The platform combines strategic advisory services with implementation capabilities, leveraging Chestnut's experience managing natural assets for forest carbon projects. "Major infrastructure projects succeed when communities, developers, utilities, and local stakeholders work together from day one," said Ben Dell, Chestnut CEO and Kimmeridge managing partner. Unlike traditional consulting firms, CNW operates as an execution-oriented platform capable of originating, structuring, and implementing projects at scale. The business builds on Chestnut's existing nature-based carbon removal operations, which began in 2022.
