• Mombak issued more than 21,000 carbon removal credits after planting nearly 15 million native trees across 12 Amazon farms.
• Google, McKinsey and McLaren Racing received credits more than two years before their expected 2028 delivery date.
• The issuance is the first completed delivery under the Symbiosis Coalition, which plans to contract over 20 million tons of nature-based removals by 2030.

Brazilian reforestation company Mombak has delivered its first Amazon carbon removal credits more than two years ahead of schedule, offering an early test of whether large-scale restoration projects can meet corporate climate commitments on time.

The company issued more than 21,000 credits, representing the removal of an equivalent number of metric tons of carbon dioxide from the atmosphere. Buyers included Google, McKinsey and McLaren Racing, which had expected to receive the credits in 2028.

Bain & Company, Climeworks, Commons and Union Square Ventures also received credits from the initial issuance. Mombak said it had sold additional credits through the spot market.

The early delivery comes as corporate buyers demand stronger evidence that carbon removal projects can produce measurable and durable climate benefits. Delayed projects and lower-than-expected credit volumes have damaged confidence in parts of the voluntary carbon market.

Restoring degraded land in the Amazon

Mombak acquires or partners with degraded farms and pastureland in the Brazilian Amazon. It then restores the land by planting diverse native tree species.

The expanding forests absorb carbon dioxide as they grow. Mombak converts the verified removals into credits that companies can purchase to address emissions that remain difficult to eliminate.

The startup has planted nearly 15 million trees across 12 farms. Its model also aims to improve biodiversity and strengthen the ecological resilience of degraded landscapes.

“The carbon market has unfortunately had a lot of challenges with underdeliveries and late deliveries from suppliers across the board,” Mombak Chief Commercial Officer Dan Harburg told Reuters.

“Being two years early in some of our first deliveries is really valuable for the relationships that we build with existing buyers and with other buyers,” he said, adding Mombak had also sold some credits on the spot market.

Mombak expects to issue another 55,000 credits in late 2026. That larger delivery will provide further evidence of whether the company can scale while maintaining verification and project quality.

Coalition receives first credits

The credits are also the first delivered under the Symbiosis Coalition, a corporate buyer group focused on nature-based carbon removal.

Members include Google and Microsoft. Together, coalition buyers have pledged to contract more than 20 million tons of high-quality nature-based removals by 2030.

The coalition seeks to provide developers with long-term purchasing commitments. Such agreements can improve revenue certainty and help projects secure the capital needed to acquire land, plant trees and maintain forests.

The first Mombak delivery gives the initiative an operational result at a time when buyers are placing greater emphasis on measurable outcomes.

“This is a proof point that when buyers commit, these projects can actually implement and deliver the impact that they say they will,” Symbiosis Coalition Executive Director Julia Strong said.

Buyers seek credible removals

Interest in Brazilian carbon projects has increased as companies search for credits tied to direct atmospheric carbon removal.

Technology companies are emerging as major buyers. Their climate strategies face added pressure from rising electricity demand linked to artificial intelligence and data center growth.

Nature-based projects can offer comparatively affordable removals while supporting biodiversity and land restoration. However, they also carry risks, including forest fires, illegal clearing, weak land governance and uncertainty over how long stored carbon will remain protected.

For corporate boards and investors, early delivery does not remove those risks. It does, however, strengthen the commercial case for projects that use conservative accounting, transparent monitoring and credible long-term safeguards.

Critics maintain that offsets can allow companies to delay direct emissions reductions. Most climate frameworks therefore position carbon removal as a complement to deep operational cuts, rather than a substitute for them.

That distinction will shape the market’s credibility. Companies purchasing credits will face continued scrutiny over whether they are also reducing emissions across their operations and supply chains.

For Brazil, the transaction highlights the potential role of carbon finance in restoring degraded Amazon land. Its wider significance will depend on whether developers can repeat early delivery at larger volumes without weakening environmental integrity or community protections.
