re.green
re.green is a Brazilian ecosystem-restoration company founded in 2021 with the goal of restoring one million hectares of degraded land across the Amazon and Atlantic Forest using only native species. In May 2024 it signed a landmark carbon-removal offtake agreement with Microsoft, later expanded in January 2025, making it one of the largest reforestation-based carbon removal deals to date. The company is backed by prominent Brazilian investors including Gávea Investimentos, Dynamo and João Moreira Salles.

Inside the project
Founded in 2021 with roughly R$389 million in initial capital, re.green commercially restores tropical forest by replanting degraded and abandoned pasturelands and selling the resulting carbon removal credits alongside biodiversity and community benefits. Its stated mission is to restore one million hectares of the Amazon and Atlantic Forest and ultimately capture on the order of 15 million tonnes of CO2 per year.
The company works exclusively with native, regionally appropriate species, identifying high-potential restoration sites using a proprietary stack of satellite imagery, drones, and cloud-based machine-learning models combined with ecological and financial data. As of the Microsoft partnership it had projects spanning roughly 33,000–34,000 hectares across Bahia, Maranhão, Pará, Mato Grosso and Rio de Janeiro, with a large share already in active restoration.
re.green's board reflects deep Brazilian financial backing: it is chaired by Marcelo Medeiros and includes figures tied to Gávea Investimentos (Arminio Fraga, Fábio Barbosa), Dynamo, and investor João Moreira Salles. The company has also drawn public climate finance, securing R$80 million from development bank BNDES (via Bradesco) to scale restoration.

Objectives
- Restore one million hectares of degraded land across Brazil's Amazon and Atlantic Forest biomes using exclusively native species.
- Deliver high-integrity, verifiable carbon removal credits to corporate offtakers such as Microsoft over multi-decade contracts.
- Recover full ecosystem function and biodiversity, not just carbon, by replanting hundreds of native species per project.
- Generate income and jobs for rural landowners and local communities while restoring degraded pasture.
Approach
- re.green identifies the highest-potential degraded sites using proprietary spatial analysis: satellite imagery, drones, and cloud-based machine-learning models, layered with ecological and financial data. Restoration is carried out with exclusively native, regional species so that the recovering forest re-establishes full ecosystem processes rather than a monoculture.
- Carbon outcomes are tracked through scientifically grounded measurement and verification, with projects pursuing Verra (VCS) certification and the Climate, Community & Biodiversity (CCB) seal. For the Microsoft deal, third-party firm Carbon Direct conducted independent technical diligence, including on-site visits to Atlantic Forest parcels and nurseries in São Paulo and Bahia and a commercial de-risking analysis of credit-delivery risk.
