High‑Integrity Forest Carbon Credits

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

Our projects are third-party validated, producing high-quality credits with transparent project documentation and durable climate benefits.

Our growing portfolio of 15 Improved Forest Management (IFM) and Afforestation, Reforestation and Revegetation (ARR) projects spans 800,000+ acres across five states, with a focus on the most up‑to‑date methodologies.

Through our carbon projects, Green Diamond tailors our forest management practices to materially increase 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.

Together, these projects form a diversified, multi-state portfolio with a strong track record of credit issuance.
