Restoring Brazil's Amazon: How Mombak Finances Reforestation

Mombak's 2026 Financing Marks a New Stage

The September 2026 announcements illustrate how Amazon restoration is moving from individual project financing toward a more structured investment market. Mombak is combining long-term financing with an operating model whose results can be assessed by investors, lenders, corporate buyers and independent carbon-removal certifiers.

BNDES approved R$200 million through the Fundo Clima's native-forest and water-resources financing line. The bank estimates that the new project will require R$457 million in total investment, with BNDES providing approximately 44% of the planned amount. The loan has a 25-year term, reflecting the unusually long investment horizon of native-forest restoration.

The planned restoration covers 7,200 hectares of degraded land in the Amazon biome, particularly Pará. BNDES expects implementation to take approximately four years, using different restoration techniques according to the conditions of each property.

The Earlier R$160 Million BNDES Operation

The new financing follows an earlier R$160 million operation approved by BNDES on August 28, 2024. The original approval comprised R$80 million from Fundo Clima and R$80 million through BNDES Finem.

According to BNDES's September 2026 update, that first operation was contracted in January 2025. It covers a planned 13,000 hectares of Amazon restoration, of which 9,400 hectares had been implemented by June 2026.

An April 2025 BNDES announcement separately described a R$100 million financing disbursement involving R$80 million from Fundo Clima and R$20 million from Finem, supported by a Santander bank guarantee. The available announcements do not fully reconcile this tranche with the earlier R$160 million approval. The April amount is therefore not added as a third independent financing operation.

BNDES's September 2026 summary identifies the two major operations as totaling R$360 million in financing associated with approximately 20,200 hectares of planned restoration.

From Degraded Cattle Pasture to a Carbon-Removal Asset

Mombak's model begins with degraded or low-productivity pastureland, much of it previously used for extensive cattle ranching. The company secures long-term control through direct property acquisitions or rural partnership agreements with landowners, then restores native vegetation using techniques suited to the conditions of each area.

According to the Symbiosis Coalition, Mombak's project commits to a 100-year durability term. Both direct landownership and long-term rural agreements are intended to support forest persistence and reduce risks associated with changes in land use or project control.

This structure is important because forest carbon projects require secure land rights beyond the initial planting period. Legal ownership, documented agreements and long-term management responsibilities affect whether restoration and carbon-removal obligations can be maintained.

The commercial product is the removal of atmospheric CO₂ through forest growth. Eligible removals can become independently certified units sold under commercial contracts. The revenue from those contracts supports the economics of restoration and long-term management.

For the new BNDES-backed project, approximately 90% of the area is expected to be restored through planting and direct seeding. The remaining 10% is expected to rely on assisted natural regeneration.

Restoration involves substantially more than planting seedlings. Land preparation, nurseries, native seeds, maintenance, invasive-species control, firebreaks, forest monitoring and independent verification must remain coordinated through the establishment and growth phases.

The model differs from a conventional forestry business focused on harvested timber. Mombak's principal climate-related commercial product is measured carbon removal, making forest growth, scientific verification and long-term protection central to the revenue model.

The distinction also matters within Brazil's wider forestry economy. Plantation forestry, timber supply and native-forest carbon restoration may require overlapping capabilities, but their objectives, revenue structures and investment horizons differ.

How Mombak Combines Different Sources of Capital

Native-forest restoration requires substantial capital before it produces significant carbon-removal revenue. Land must be secured, restoration activities financed and forests maintained while trees grow. Investors and lenders therefore need structures that accommodate the time between expenditure and commercial delivery.

Mombak uses several financing channels, each performing a different function. Their reported values should not be added together mechanically, because fund capital, project loans, bond proceeds and future purchase contracts can overlap in the financing of individual projects.

Fund I and the Institutional Investor Base

Reuters reported that Mombak's first fund raised US$120 million from investors including an AXA fund, CPP Investments and Bain Capital. Brazilian financial outlet Reset also identified the Rockefeller Foundation among investors associated with Fund I.

The fund supported restoration projects across 15 Amazon farms. By September 2026, Mombak reported nearly 15 million native trees planted across its operating portfolio.

Amazon Reforestation Fund II

Mombak announced the first close of its second fund in September 2026. The vehicle aims to raise US$150 million in equity capital and has access to the R$200 million BNDES credit line announced at the same time.

The amount raised in the first close and the complete composition of the new fund's investors were not publicly disclosed in the reviewed reporting. The US$150 million figure is the target, not confirmation that the full amount has been secured.

Reset also reported that Mombak had been selected in a BNDESPar climate-investment process, potentially making it eligible for a separate equity investment. That participation remained under evaluation and should not be treated as committed additional financing.

This combination of equity, long-term credit and future carbon-removal demand illustrates the financing structure emerging around forest restoration. The specific allocation between funds, project companies and lenders still requires transaction-level documentation.

The World Bank Outcome Bond Links Investor Returns to Forest Restoration

The World Bank's Amazon Reforestation-Linked Outcome Bond provides a separate example of how Mombak's restoration activities can be financed through international capital markets.

Issued in August 2024, the nine-year bond has a nominal value of US$225 million. It is a principal-protected World Bank security in which investors receive a guaranteed fixed coupon and a variable component linked to the generation and monetization of carbon-removal units.

The transaction mobilizes approximately US$36 million for Mombak-related restoration activities. According to the World Bank's transaction documentation, investors forego part of their ordinary coupon payments, and the equivalent financing is channeled through a structure involving HSBC.

The distinction between the two figures is essential. The US$225 million represents the bond's principal value, with proceeds supporting the World Bank's wider development activities. Approximately US$36 million is the amount separately identified to support Mombak's reforestation activities.

The World Bank's case study describes scheduled financing installments conditional on project milestones. Investors' variable returns are ultimately linked to the carbon-removal units generated and monetized through the transaction, with Microsoft's underlying purchase agreement providing the commercial demand.

Details of the transaction are available in the World Bank's original announcement and its subsequent issuance update.

Verified Carbon Removal Is the Critical Commercial Milestone

Financing and planting establish the physical basis of a restoration project. Independent certification determines whether measured carbon-removal outcomes can enter a formal commercial delivery process.

On July 1, 2026, Isometric announced the issuance of 21,771 reforestation certificates from Mombak's Reforesting the Brazilian Amazon Project 1. Its public registry records an issued quantity of 21,771.53 units.

The registry identifies the project under code 84R7, with Reforestation Protocol version v1.1. The project's crediting period runs from March 31, 2023 to March 30, 2073.

The registered project restores degraded pastureland using native-species planting and assisted natural regeneration. Isometric identifies direct land acquisition and long-term rural partnership agreements as mechanisms supporting land rights and forest permanence.

Dynamic Baselines and Albedo Accounting

Isometric's methodology uses dynamic baselines to compare project outcomes with comparable unrestored land. Its certification framework is intended to account only for removals beyond what would otherwise have occurred.

The Reforestation Protocol also considers albedo changes. Albedo refers to the proportion of incoming solar energy reflected by a surface. Restoring forest cover can change that reflectivity, so accounting for its climate effect is relevant when evaluating net cooling.

Isometric states that its protocol does not admit areas where the projected warming effect from albedo changes would outweigh the intended climate benefit of reforestation.

These methodological provisions distinguish the issued reforestation certificates from claims based only on the number of trees planted or theoretical forest growth.

Long-Term Reversal Risk

Forest carbon remains exposed to reversal. Fire, disease, land-use changes and unsuccessful long-term management can threaten stored carbon even after initial certification.

Isometric's public registry records 2,286.012 certificates contributed by Mombak to the Forestry Buffer Pool. The registry reports an average reversal-risk assessment of 10.5% across the project's removals and no reversals to date.

The buffer mechanism is designed to help address potential future carbon losses. It does not make the physical risk of forest reversal disappear.

Corporate Buyers and the Symbiosis Coalition

Carbon-removal purchase agreements are an important part of Mombak's financing model because they establish demand before the full forest-restoration cycle is complete. Buyers commit to future removals, while the project developer must deliver certificates that meet applicable contractual and certification conditions.

Microsoft: Up to 1.5 Million Tonnes

In December 2023, Microsoft announced an agreement to purchase up to 1.5 million carbon-removal credits from Mombak's native-forest restoration projects by 2032.

The agreement established a substantial long-term demand commitment for the company's emerging restoration portfolio and subsequently became part of the commercial framework supporting the World Bank's outcome bond.

Google: Expanding Contracted Demand

Google announced its first Mombak agreement in September 2024, covering 50,000 tonnes of carbon removal.

In November 2025, Google disclosed another agreement for 200,000 tonnes, four times the size of its first purchase. The company also described the use of Google DeepMind's Perch AI to help quantify biodiversity benefits associated with forest restoration.

These agreements indicate demand for future certified removals. They should not be interpreted as confirmation that all contracted tonnes have already been issued or delivered.

Mombak Becomes the First Symbiosis Project

The Symbiosis Coalition was founded by Google, Meta, Microsoft and Salesforce in 2024 to expand demand for high-integrity nature-based carbon removal. The initiative was launched around a collective ambition to contract up to 20 million tonnes of nature-based removals by 2030.

In November 2025, Symbiosis announced Mombak's Reforesting Brazil at Scale as its first formally selected project. The coalition reported assessing 185 projects from more than 40 countries before announcing the selection.

Symbiosis reported that Google and McKinsey had purchased a combined 215,000 tonnes of carbon removal from Mombak under their coalition commitments. The announcement also referenced Microsoft's earlier 1.5 million-tonne agreement, signed before the coalition's launch.

These contract figures are not necessarily separate from Google's other publicly announced purchases. Individual buyer commitments and coalition-reported volumes should not be added together without checking their contractual scope.

The Symbiosis selection process evaluates carbon accounting, ecological integrity, durability, community benefits and transparency. Mombak's project was recognized for restoring degraded pastureland using diverse native tree species, its long-term land arrangements and its approach to involving local communities.

Symbiosis also highlighted Mombak's efforts to address potential displacement of cattle production. The company provides performance-linked financing to support more intensive cattle management on existing pastureland, aiming to reduce the risk that restoration simply shifts deforestation pressure elsewhere.

This is relevant to the economics of restoration because land use, rural livelihoods and carbon permanence are connected. Commercial credibility depends partly on whether restoration can coexist with agricultural activity without transferring environmental damage to other areas.

Salesforce and Additional Corporate Demand

In September 2026, Mombak announced a new multiyear carbon-removal purchase agreement with Salesforce. Salesforce is also a founding member of the Symbiosis Coalition.

The volume, price and exact delivery period of the Salesforce agreement were not publicly disclosed in the reviewed reporting.

Mombak and BNDES expect future demand to expand beyond the technology sector into industries such as mining, steel and oil and gas. That broader market remains a commercial expectation rather than a demonstrated volume of contracted demand.

Who Received Mombak's First Reforestation Credits?

In August 2026, Mombak announced deliveries of its first independently certified reforestation credits to a group of international buyers.

• Google — technology and carbon-removal procurement.
• McKinsey & Company — consulting and a Symbiosis Coalition participant.
• Bain & Company — consulting and a Symbiosis Coalition participant.
• Climeworks — carbon-removal company.
• Commons — climate-focused consumer technology.
• McLaren Racing — motorsport organization.
• Union Square Ventures — investment firm.

The deliveries included fulfillment of existing offtake agreements as well as new commercial transactions. Mombak said that deliveries to Google, McKinsey and McLaren Racing occurred more than two years ahead of their original expectations.

This provides evidence that the business has moved beyond forward contracting into the delivery of issued carbon-removal certificates.

The commercial achievement does not establish the financial profitability of the wider portfolio. Contract prices and individual revenue recognition remain only partly visible.

The Next Test: Scaling Verified Carbon-Removal Issuance

The July 2026 certification milestone created an observable starting point for Mombak's commercial deliveries. The next question is whether issued volumes can increase as restoration activity expands.

In September 2026, Mombak indicated that it expected a second issuance of approximately 80,000 tonnes by December 2026. If achieved, the year's total issuance would exceed 100,000 tonnes.

This figure remains a forward-looking company estimate. It is not included in the 21,771 certificates already announced in July or the 21,771.53 issued units visible in the reviewed Isometric project register.

Earlier reporting had indicated a smaller expected subsequent issuance. The approximately 80,000-tonne figure reflects Mombak's later September 2026 outlook and should not be described as a verified result.

Scaling certification is commercially important because restoration investment must ultimately produce recognized units that can satisfy contractual obligations. Increasing the area under restoration does not automatically increase certified deliveries at the same rate.

Future issuance will depend on forest growth, measurement evidence, protocol requirements, independent verification and the timing of eligible carbon-removal periods.

Project Economics Depend on Time, Land and Carbon Delivery

The financial logic of large-scale reforestation differs from that of a conventional industrial plant. Investment begins before the principal carbon-removal product has been generated, while a substantial part of project value may emerge over many years.

The new BNDES-backed project provides an illustrative investment indicator. Estimated total investment is R$457 million for 7,200 hectares. Dividing these figures produces approximately R$63,470 in planned investment per hectare.

This Econosur calculation is based on the disclosed investment and area figures. It represents an average total project-investment indicator, not a confirmed planting cost, annual operating cost or cost per certified tonne.

BNDES projects more than 4.7 million tonnes of CO₂ removals over 50 years from the new operation. This long-term estimate is relevant to the project's financing case but cannot be treated as delivered inventory.

Nor should it be used mechanically to calculate a reliable carbon-removal price. The financial result will depend on actual forest growth, credit issuance, timing, operating expenditure, borrowing costs, contract prices and risk provisions.

Financing structure matters because these costs and revenues occur at different times. Long-term credit can help align capital availability with the biological growth cycle, while investor funds absorb project-development exposure.

Forward purchase agreements provide evidence of future demand and may support financing decisions. They do not eliminate the need to deliver the carbon-removal units under the applicable contractual conditions.

The central commercial question is whether verified carbon-removal revenue can cover the full costs of restoration, financing, protection and long-term forest management while providing an acceptable return to investors.

Reforestation Is Developing Its Own Industrial Supply Chain

Mombak's model also creates economic activity beyond carbon-credit transactions. A large restoration program requires land management, biological inputs, transport, labor, equipment, field operations, specialist services and monitoring.

BNDES identifies soil preparation, nursery plants, seeds, planting, maintenance, forest monitoring and supporting infrastructure among the activities financed under the new operation.

The bank estimates up to 440 direct jobs and 65 indirect jobs during implementation, with approximately 50 positions maintained after the establishment phase. These are projected employment effects, not verified jobs already created by the new operation.

Scaling restoration can generate demand for native-seed collection, nurseries, field contractors, ecological expertise, logistics, equipment maintenance, remote sensing, mapping, verification and data management.

Pará's role matters because the operating geography combines degraded agricultural land, tropical forest ecosystems and the practical constraints of projects spread across multiple rural properties.

Local supplier capacity, seasonal access, roads, workforce availability and appropriate native species can influence the cost and reliability of implementation. These factors vary between properties and restoration methods.

This distinction is central to Econosur's analysis of South American project markets: visible financing and project announcements provide a starting point, while supplier selection, purchasing processes and actual implementation require further verification.

Commercial Risks Extend Beyond the Initial Investment

The development of an investable forest-restoration market depends on whether projects can deliver measurable carbon removals consistently over long periods.

Mombak's financing structure must absorb several forms of uncertainty.

• Restoration performance: tree survival, rainfall, soil conditions, fire, disease and maintenance affect forest growth and carbon storage.
• Land tenure: ownership, rural partnership agreements and long-term project control must support restoration and contractual obligations.
• Carbon verification: projected uptake does not automatically qualify for certification. Methodologies, baselines, monitoring and independent assessment determine eligible issuance.
• Market risk: future credit prices, buyer concentration, corporate climate commitments and demand diversification remain uncertain.
• Financing risk: borrowing costs, investor requirements, project expenditure, loan disbursements and delivery timing affect liquidity and returns.
• Reversal risk: forest carbon can be lost after certification. Protection, monitoring, buffer mechanisms and contractual provisions address the durability of the product.
• Scaling risk: operating results achieved on established farms may not be replicated at the same cost or speed across new properties.
• Leakage risk: relocating cattle or other economic activity to new areas could undermine restoration benefits if it causes additional land-use pressure elsewhere.

The July 2026 certification milestone reduces uncertainty about Mombak's ability to obtain independently issued reforestation certificates. The Symbiosis selection also provides evidence of external technical assessment and corporate buyer confidence.

Neither development establishes profitability across the full portfolio or eliminates long-term ecological and commercial risks.
