Chestnut Carbon, a nature-based carbon removal developer, has raised an additional $90 million in Series B financing, bringing its total Series B round to $250 million.
The investment, led by existing partner CPP Investments, underscores the growing demand for high-quality, verifiable carbon removal solutions that can help companies and communities meet their net zero goals.
This milestone follows Chestnut’s recent closing of an interesting non-recourse project finance credit facility of up to $210 million, the first-of-its-kind bank financing for a U.S. voluntary carbon removal afforestation project.
Together, these moves position the company at the forefront of scaling sustainable forestry initiatives nationwide.

Chestnut Carbon is focused on transforming marginal croplands and pastures into biodiverse forests across the United States.
Its afforestation projects are designed to:
🌱 Capture and store carbon through healthy, resilient ecosystems
🌱 Generate Gold Standard® verified carbon credits for corporate partners
🌱 Conserve forestlands while creating long-term economic benefits for landowners
Already, Chestnut has acquired more than 60,000 acres across eight southern states. Projects like the El Ranchos site in Jefferson County, Arkansas (2,367 acres with 1,843 earmarked for afforestation), and the Rooks Ranch in Dallas County, Alabama (1,422 acres with 1,177 for afforestation) demonstrate the scale at which the company is operating.
Bill Rogers, Head of Sustainable Energies at CPP Investments, emphasized the importance of Chestnut’s model in a global context.

By pairing private capital with ecological restoration, Chestnut is demonstrating how climate finance can move beyond offsets toward long-term, verifiable impact.

As Greg Adams, Chief Financial Officer of Chestnut Carbon, notes,
“We’re committed to helping our customers meet their decarbonization goals and ensuring they can rely on us as their trusted partner in the process.”
With $250 million secured in Series B funding and a first-of-its-kind project finance facility in place, Chestnut Carbon is charting a path for large-scale, nature-based solutions to play a central role in the global climate response.
By aligning investors, corporations, and landowners, the company is building not just forests but also a framework for a more sustainable future.
