Mombak's $150 million Amazon fund shows capital is the constraint

Mombak has the hard half of the carbon removal trade behind it, having secured a first close of its second Amazon reforestation fund and signed Salesforce to a multiyear carbon removal offtake that adds the software company to a buyer list including Google, Microsoft and McLaren Racing. Amazon Reforestation Fund II is targeting $150 million for restoration projects across the Brazilian Amazon, with access to a $38.88 million credit line from Brazil's Climate Fund operated by the state development bank BNDES.

The three capital sources do different work: the fund pays for planting, the credit line adds borrowing capacity a vehicle this size would struggle to assemble from commercial lenders, and the offtake turns what grows into a contracted revenue stream. Blended finance usually means a grant layered under a project; here the public piece is roughly a quarter of the target and behaves like senior money standing beside equity, a structure that repeats — the same logic seen in Gennaker's $3.5 billion close, where sixteen commercial lenders took construction risk only with the EIB in the syndicate.

The first fund is the evidence base, having raised $120 million from investors including an AXA fund, CPP Investments and Bain Capital to finance restoration across 15 Amazon farms that yielded nearly 15 million native trees. Mombak issued its first reforestation carbon removal credits earlier this year and expects a second, substantially larger issuance of about 80,000 metric tons by the end of 2026. The coverage does not say how much the first close of Fund II brought in, and for a vehicle that will lean on corporate and development capital, that number matters more than the target.

Removal credits are the sturdier product in this market because they are tied to carbon dioxide taken out of the atmosphere rather than to emissions avoided, and technology companies have become major buyers as they manage emissions tied to expanding AI and data center infrastructure. The terms they are signing suggest procurement discipline rather than patronage; Mombak describes the Salesforce arrangement as a multiyear offtake.

Run the numbers on the first fund and the ceiling on the second becomes visible: $120 million across 15 farms is about $8 million per farm, and if Fund II deploys at that density, the $150 million target plus the BNDES credit line would carry roughly 24 farms, a doubling of the program and little more. Silva says productivity gains and improved reforestation techniques are lowering costs, which should stretch each dollar further, but a structure that needs a state development bank for a quarter of its firepower is telling you that equity alone does not finance standing forest at institutional scale.

Chief executive Gabriel Silva told Reuters, "We are only raising this second fund because we proved over the last five years that there is a business, there is an industry and there is a market for this product." The Salesforce contract is the receipt for that claim, but the fund's design concedes scale: this is a repeat vehicle rather than a large one, needing a development bank and a corporate offtake to close.

The pitch to a wider buyer base rests on cost, and Silva ties accessibility to productivity gains and better technique — the right lever, since removal credits compete against every other line in a corporate sustainability budget. A cheaper credit is also a thinner one unless volume scales faster than price falls, which suggests the value of the Salesforce agreement lies less in its size, which is undisclosed, than in its duration.

The pattern holds: transition capital is moving to the offtake and the term sheet, where risk allocation gets negotiated line by line. The September 21 report on Symbiosis covered the same ground from the other direction, with forty million tons of nature-based removals sitting behind contracts whose innovation is how the risk is split. Mombak's Salesforce agreement belongs to that family, because offtakes give a developer visibility over future revenue, which addresses the uncertainty over future buyers that otherwise stalls emerging removal projects at the financing stage. They do not plant anything; the trees come from the fund and the credit line, and the contract converts them into a sellable credit years later.

Silva expects the buyer base to widen beyond technology companies, saying, "Over time, you can expect announcements involving companies that are not Big Techs." BNDES's socio-environmental director, Tereza Campello, said technology companies are reassessing climate targets, though the excerpt of her remarks does not indicate which way that reassessment runs. The Salesforce signing is evidence toward more buying rather than less, and the fund's economics depend on a second wave arriving — the likely candidates being heavy industry and transport, where abatement is expensive and disclosure obligations are hardening.

Two numbers will settle it: the roughly 80,000-ton second issuance due by the end of 2026, which will test whether measurement and verification can keep pace with the offtakes now being signed — the diligence question raised by Microsoft's six-million-credit round in August, when soil-level measurement and dynamic baselines moved out of marketing and into underwriting — and Fund II's final close, with the size of the BNDES line standing beside it. If the credit line grows with the fund, reforestation capital is scaling; if it stays fixed while the target rises, public balance sheets are carrying the difference. The 80,000-ton issuance lands first.
