Chestnut Carbon reported that it has now restored roughly 70,000 acres of land to native forests in the Southeast, approximately doubling its footprint in the region over the past year. Since 2022, the firm has planted 46.7 million trees, including 24 million during the most recent season across nine states.
Its flagship Chestnut Sustainable Restoration Project is now described as 1.5 times the size of Acadia National Park and five times the size of Manhattan, and is cited as the largest U.S.-based afforestation project on the Gold Standard registry. The project extends along 350 miles of waterways, where concurrent river and stream restoration aims to enhance water quality and other environmental co-benefits.
Operationally, Chestnut Carbon has been supported by a first-of-its-kind debt facility secured in 2025, which has enabled accelerated land acquisition and planting. The company is also working with partners such as ArborGen and DDK Forestry & Real Estate to secure seedlings and meet Forest Stewardship Council standards, helping to de-risk execution and supply chain constraints.
The company emphasized measures to boost ecological quality and carbon durability, including deploying 301,000 Funga-inoculated seedlings to improve soil recovery and diversifying species with longleaf and shortleaf pine. These initiatives are intended to build climate-resilient, high-permanence carbon assets and support a premium positioning in the voluntary carbon market.
Chestnut Carbon highlighted that its projects supported an estimated 768 jobs, generated $48.8 million in regional economic output, and produced $7.4 million in tax revenues from 2022 through 2025. These figures point to growing rural economic impact and may strengthen community partnerships as activities scale further in 2026.
The company also launched a recurring newsletter focused on its nature-based carbon removal activities and broader market commentary. This communication effort is designed to provide updates on project milestones, field progress, and the evolving carbon and climate landscape, potentially improving transparency for investors and corporate buyers.
In addition, Chestnut Carbon drew attention to a new whitepaper analyzing Microsoft’s recent pause in carbon removal procurement, framing it as a possible turning point for the voluntary carbon market. The company suggests this shift could encourage a broader base of buyers, reduce demand concentration risk, and support more mature price discovery over time.
Collectively, the week’s developments underscore Chestnut Carbon’s dual focus on scaling high-integrity afforestation projects and strengthening its market presence as a provider of premium carbon removal credits. If current execution levels and verification standards are maintained, these moves could support greater carbon credit capacity and more resilient demand dynamics for the company.
