Chestnut Carbon now estimates it has restored roughly 70,000 acres of land to native forests in the Southeast, roughly doubling its footprint over the past year. Since 2022, it has planted 46.7 million trees, including 24 million in the most recent season across nine states, supported by partners such as ArborGen and DDK Forestry & Real Estate.
The firm highlighted its flagship Chestnut Sustainable Restoration Project, described as 1.5 times the size of Acadia National Park and five times the size of Manhattan. The project, cited as the largest U.S.-based afforestation effort on the Gold Standard registry, spans 350 miles of waterways with concurrent river and stream restoration to enhance water quality and co-benefits.
Operational scaling has been underpinned by a first-of-its-kind project-level credit facility of about $210 million, characterized as a landmark structure in the U.S. voluntary carbon market. This debt financing has enabled accelerated land acquisition and planting, signaling institutional appetite for nature-based carbon assets and potentially improving revenue visibility.
Chestnut Carbon reported ecological upgrades including 301,000 Funga-inoculated seedlings aimed at soil microbiome restoration and faster carbon storage. Expanded plantings of longleaf and shortleaf pine in Georgia and Arkansas are intended to bolster biodiversity, climate resilience, and the perceived durability of the company’s carbon credits.
The company also quantified its regional economic impact, citing support for an estimated 768 jobs, $48.8 million in economic output, and $7.4 million in tax revenues from 2022 through 2025. These figures may strengthen community and landowner relationships, which are critical for maintaining and expanding long-term project pipelines.
On the commercial side, Chestnut Carbon is targeting new demand segments by attending the 2026 Green Sports Alliance Summit in Cleveland to engage sports and entertainment organizations. The firm is positioning its forest carbon removal projects as tools to offset emissions from team travel and game-day operations, while emphasizing local environmental and community benefits.
To enhance market visibility and transparency, the company launched a recurring newsletter and released a whitepaper examining Microsoft’s pause in carbon removal procurement. Chestnut Carbon frames this shift as a potential catalyst for a more diversified buyer base and more mature price discovery in the voluntary carbon market, which could reduce concentration risk over time.
Overall, the week’s developments showcase Chestnut Carbon’s dual focus on scaling large, high-integrity afforestation projects and innovating in project finance and market outreach. If current execution and verification standards are maintained, the company appears positioned to expand credit supply and broaden its customer base in the evolving voluntary carbon space.
