High‑Integrity Forest Carbon Credits

Green Diamond develops, owns and manages U.S.‑based forest carbon projects across Compliance and Voluntary markets.

We offer buyers rigorously third-party validated credits with transparent project documentation, regulatory alignment and durable climate benefits. Our portfolio of 14 Improved Forest Management (IFM) and Afforestation, Reforestation and Revegetation (ARR) projects spans 700,000+ acres across five states.

We apply the latest methodologies to tailor forest management practices that materially increase on-land carbon sequestration. This added carbon is verified under rigorous protocols, generating high-integrity credits—both removals and avoided emissions—while delivering meaningful benefits to forests and local communities.

Green Diamond Carbon by the Numbers

Growing forests absorb and store carbon dioxide, making forest carbon projects an effective, near-term climate mitigation strategy. Green Diamond is one of the largest owner-operators of IFM projects in the U.S., with a growing ARR portfolio. Together, these projects form a diversified, multi-state portfolio with a strong track record of credit issuance.

Improved Forest Management (IFM)

IFM projects involve a substantive, long‑term change in Green Diamond’s forest management practices. By extending rotations relative to baseline management, these projects increase on‑landscape carbon storage while preserving timber economies and providing essential long‑lived wood products. IFM projects are an essential near‑term climate change mitigation solution.

Afforestation, Reforestation and Revegetation (ARR)

ARR projects draw on Green Diamond’s in‑house land acquisition and reforestation expertise—with 25,000 acres reforested each year—to restore degraded agricultural and pasture lands to productive forest ecosystems. These projects are designed for long‑term carbon sequestration and sustained forest management while supporting recreation and conservation.

Co‑Benefits

As nature‑based solutions, IFM and ARR projects abound in co‑benefits, including improved soil quality, erosion control, contiguous animal habitat and biodiversity uplift. Forest carbon projects also support forest industry jobs and local timber economies for the long‑term. In many cases, public access for recreation on our carbon projects is also a tangible benefit to local communities.

Green Diamond believes carbon projects offer a way to participate meaningfully in addressing the climate crisis while allowing us to continue to be good stewards of the land.
