Nature-based carbon removal (reforestation). Re.Green is Brazil’s leading ecological restoration company, on a mission to reforest degraded Amazon and Atlantic rainforest land at massive scale and generate high-quality carbon removal credits. It acquires or partners on deforested lands and restores native forests, planting diverse species to rebuild ecosystems. The carbon sequestered is sold as credits to corporations seeking credible offsets.

Growth stage (Project developer). Backed by significant private capital completed a $79M Series A in late early 2022. Key investors include BW, the family office for Unibanco founding family Moreira Salles, and major asset managers like Dynamo, Lanx Capital and Gávea (led by ex-central bank governor Arminio Fraga). With these funds, Re.Green is scaling operations and is likely not seeking traditional venture rounds but rather project capital and strategic partnerships (though a Series B for corporate growth could occur).

To date Re.Green has planted over 4.4 million trees covering 11,000 hectares in Brazil. It has already restored 15,500 ha under its first phase and just signed a second agreement to restore an additional 17,500 hectares – totaling 33,000 hectares committed with Microsoft as the buyer of ~3.5 million metric tons of CO₂ removal over 25 years. Re.Green has acquired ~26,000 hectares of land from ranchers and also just partnered with a large agribusiness (AgroPenido) to reforest 600 hectares of privately owned farmland. Revenues come from multi-year carbon credit offtake agreements clients such as Microsoft. The team is close to 100 people, including forestry scientists and a seasoned CEO (Thiago Picolo) with private equity experience in Latin America.

Huge. Each hectare reforested can sequester roughly 500+ tons CO₂ over 50 years. Re.Green’s current commitments (33k ha) could remove on the order of 6–8 million tons of CO₂ in coming decades. Beyond carbon, restoring native forests in the Amazon and Atlantic Forest yields biodiversity gains (habitat for endangered species) and hydrological benefits (improving rainfall cycles and water security). The projects create local green jobs and support communities, aligning with several UN Sustainable Development Goals. If Re.Green achieves its goal of 1 million hectares restored (about twice the size of Delaware), the climate impact would be on the gigaton scale of CO₂ removal, alongside preserving immeasurable ecosystem value.

Supported by prominent investors Moreira Salles (of the Itaú banking family), Lanx Capital, Principia, Dynamo, and Gávea have equity stakes. Corporate buyers include Microsoft(two landmark deals totaling 33k ha). On partnerships, Re.Green works with local NGOs and research institutes to ensure scientific rigor in its restoration methods. It’s also coordinating with Brazil’s government as the country prepares to host COP30, showcasing Re.Green as a model for private-sector-led reforestation.

Scale and integrity. While many offset projects have faced credibility issues, Re.Green focuses on high-integrity reforestation (native species, permanent protection) to generate verifiable carbon removal credits – a cut above typical avoided-deforestation credits. By owning land and planting trees itself (rather than just funding others), it controls the entire process and quality. The team’s mix of financial acumen and on-the-ground forestry expertise allows it to navigate both investor expectations and operational challenges in remote regions. Re.Green’s strong backing and multi-year offtakes also give it a capital moat – it can undertake large projects that smaller developers cannot.

Political/regulatory risk in Brazil – changes in land use laws or carbon market regulations could affect operations (though the current government is climate-friendly). Execution risk on planting so many trees it requires careful community engagement and ecological knowledge to ensure trees survive and forests become self-sustaining. Thus far, Re.Green’s results are encouraging, mitigating this risk with data (80+ native species planted, high survival rates). The carbon credit market volatility is another risk prices can fluctuate, but demand for high-quality removals is strong and growing. Opportunities include expanding into other Latin American countries or scaling through joint ventures (e.g., partnering with timber or agriculture companies to reforest unproductive lands). Additionally, as corporates race toward net-zero pledges, Re.Green is positioned as a premier supplier of nature-based carbon removals, potentially allowing premium pricing and long-term contracts (it already commands ~$50–100/ton for its credits in private deals). Overall, Re.Green offers family offices a blend of impactful philanthropy-like outcomes (forest restoration) with a commercial model backed by real cash flows from Fortune 500 companies.
