Google Deepens Amazon Reforestation Partnership with Mombak in Landmark Carbon Removal Deal

Google has signed a major new agreement with Brazil-based reforestation company Mombak to purchase 200,000 tons of verified CO₂ removals generated through the restoration of degraded land in the Amazon rainforest. The deal, which builds on a 50,000-ton purchase announced last year, marks a substantial step forward in Google’s nature-based carbon removal strategy. Can this scale of reforestation deliver lasting climate and biodiversity gains or will verification and permanence risks limit its long-term impact?

 

Expanding a High-Integrity Carbon Partnership

 

Mombak, founded in 2021, specializes in restoring unproductive pasturelands across the Amazon using native and biodiverse tree species. Its model combines large-scale reforestation with assisted natural regeneration, an approach designed not only to sequester carbon but also to rebuild degraded ecosystems and support local livelihoods. Under the new agreement, Google’s expanded purchase brings the total volume of carbon removal credits contracted from Mombak to 250,000 tons. Each credit represents one ton of carbon removed from the atmosphere through verified and permanent forest regrowth. The investment underscores Google’s broader goal to neutralize residual emissions through durable, nature-based carbon sinks rather than temporary offsets. By prioritizing high-integrity forest projects that are independently verified and monitored, the partnership aims to set a higher benchmark for corporate participation in the voluntary carbon market especially at a time when scrutiny of offset credibility continues to intensify.

Building the Market for Nature-Based Carbon Removal

 

The collaboration also aligns with Google’s role in the Symbiosis Coalition, an initiative launched in 2023 alongside Meta, Microsoft, and Salesforce. The coalition’s mission is to accelerate the scale-up of reliable, nature-based carbon removal by committing to purchase up to 20 million tons of verified credits over time. Mombak has been chosen as the first project under this coalition—a significant endorsement of its methodology and governance standards. Its projects integrate ecological science, community engagement, and financial transparency, creating a framework that other carbon removal developers may emulate. For the participating tech giants, such partnerships not only help achieve net-zero commitments but also serve as a testing ground for scalable models that blend technology, nature restoration, and corporate accountability.

 

Harnessing AI to Measure Biodiversity Gains

 

In addition to carbon removal, Google and Mombak are pioneering an innovative AI-driven biodiversity monitoring collaboration. Google DeepMind’s Perch team will work with Mombak to assess the ecological health of restored areas by analyzing bioacoustic data from the Amazon. The Perch model listens to hours of soundscape recordings from bird calls to insect hums to evaluate species diversity and ecosystem vitality. This technology will provide new insights into how reforestation projects can regenerate complex ecological networks, going beyond carbon accounting to measure tangible biodiversity recovery. Such partnerships between climate technology and ecological science could redefine how companies evaluate the broader environmental impact of their carbon investments.

 

Integrating Climate Goals with Local Impact

 

Mombak’s projects go beyond carbon capture, they also contribute to Brazil’s social and economic development goals. Each reforestation site creates jobs in local communities, supports indigenous stewardship, and improves watershed resilience. Restoring biodiversity on former pasturelands helps reverse soil degradation and strengthens natural carbon storage capacity across the Amazon basin. 

 

According to Google’s Carbon Removal Commercialization Program Manager, Reilly O’Hara, Mombak’s approach balances “high-integrity reforestation using native, biodiverse forests and strong durability safeguards with industrial-scale operations.” This combination, O’Hara added, is essential to achieving both environmental credibility and meaningful impact at scale.

The Road Ahead for Corporate Carbon Removal

 

As companies face growing pressure to move from carbon offsets to verified removals, Google’s partnership with Mombak signals a shift toward projects that deliver measurable, long-lasting results. With the Symbiosis Coalition providing an advance market commitment and AI tools like Perch enhancing transparency, nature-based removals may soon reach the scale needed to complement engineered solutions such as direct air capture. However, sustaining ecological gains will depend on continuous monitoring, community involvement, and adaptive management to counter risks from fire, land-use change, and political shifts in the Amazon. If successful, Google’s collaboration with Mombak could become a blueprint for how corporate climate finance, technology innovation, and ecosystem restoration converge to deliver durable progress on both climate and nature.
