Climate Impact Partners (CIP) has completed the purchase of one million tonnes of nature-based carbon removal credits from GreenTrees, the largest reforestation initiative in the United States. The transaction was executed on behalf of an undisclosed Fortune Global 500 corporate client.
The transaction utilizes a “staggered spot” financial structure, which combines already issued carbon credits with newer vintages currently undergoing formal registry verification. This mechanism is designed to reduce delivery risk for corporate buyers while accelerating cash flows directly to regional landowners before final credit issuance.
Operated by ACRE Investment Management, the GreenTrees Mississippi Alluvial Valley Reforestation Project converts marginal, degraded agricultural land back into native woodland ecosystems. To date, the project has planted more than 50 million trees across 140,000 acres, sequestering nearly 8 million tonnes of atmospheric carbon. The initiative involves approximately 600 landowners in low-income regions across the Mississippi Delta, restoring regional watersheds and reconnecting migratory corridors for vulnerable wildlife.
The project is the first afforestation, reforestation, and revegetation (ARR) development globally to issue carbon credits approved under the Core Carbon Principles (CCPs)—the quality benchmark established by the Integrity Council for the Voluntary Carbon Market (ICVCM).
To satisfy these compliance standards, the project deploys proprietary digital measurement, reporting, and verification (dMRV) technology managed via ACRE IO. The digital system provides frequent, data-driven canopy and soil carbon measurements to guide regional replanting efforts and automate third-party audits.
This latest agreement expands a multi-year funding pipeline between the two environmental organisations. Since 2020, Climate Impact Partners has directed corporate finance into the GreenTrees network to secure the purchase of nearly 2.5 million tonnes of carbon removals.
Sheri Hickok, Chief Executive Officer of Climate Impact Partners, commented, “This million-tonne agreement demonstrates how the carbon market is delivering measurable, large-scale climate impact today. It reflects how we work in partnership with both project developers and corporate clients to match climate ambition with high quality supply.”
Chandler Van Voorhis, Co-Founder of the GreenTrees platform, added, “The carbon market is the catalyst, turning projects into scalable, sustainable enterprises to help companies achieve their climate goals while driving value and impact for marginalised landscapes and communities.”
