In its biggest carbon removal agreement to date, Google will finance the reforestation of degraded pastureland in the Amazon through Brazilian startup Mombak, marking a major shift in how tech companies source high-quality carbon offsets. The deal will cover 200,000 metric tons of CO, quadrupling Google's previous engagement with Mombak.

The move comes as the tech sector faces mounting pressure to balance its energy-intensive data centers-especially for AI-with credible climate strategies. According to Google's environmental report, its scope 2 emissions (mostly from purchased electricity) have surged, more than tripling since 2020 to 3.1 million tons last year.

While the value of the deal wasn't disclosed, its implications are clear: the search giant is moving away from widely criticized REDD credits-which pay for preserving forests potentially at risk-and toward restorative projects that remove carbon directly by planting trees.

"The most derisked technology we have to reduce carbon in the atmosphere is photosynthesis," said Randy Spock, Google's head of carbon credits and removal. Mombak's model of turning exhausted pastureland back into jungle aligns with the company's stricter standards and has positioned it as a leader in Brazil's emerging reforestation economy.

The agreement is also timely, as Brazil prepares to host the COP30 climate summit in Belém, branding it the "Forest COP" and spotlighting Amazon restoration as a global priority. Mombak is the first reforestation project to be approved by the Symbiosis Coalition, a group of buyers including Google, Microsoft, Meta, and McKinsey, committed to contracting over 20 million tons of nature-based offsets by 2030.

Only 1 of 185 reviewed projects has met Symbiosis's rigorous standards so far-underscoring the credibility challenge in the carbon credit space. These standards demand transparent carbon accounting, long-term ecological benefits, and support for biodiversity and local communities.

The scarcity of top-tier carbon offsets has driven prices upward. While REDD credits may cost under $10 per ton, reforestation projects like Mombak's can fetch $50-$100 per ton. "There's way more demand than supply right now," said Mombak CEO Gabriel Silva, though he notes that producers are working to reduce costs without compromising integrity.

As more corporations seek measurable, trustworthy carbon removal, Brazil's reforestation sector-if it maintains its focus on quality-could become a key supplier in the global climate solution portfolio.
