Brazilian reforestation company Mombak has delivered its first carbon removal credits more than two years ahead of schedule, marking a significant development for the growing nature-based carbon removal market. The credits were purchased by major companies including Google, McKinsey, McLaren Racing, Bain & Company and Climeworks. Mombak is restoring degraded farmland and pasture in the Brazilian Amazon by planting native, biodiverse tree species. So far, the company has planted nearly 15 million trees across 12 farms, with its first issuance representing more than 21,000 tonnes of CO₂ removed from the atmosphere.
The project demonstrates how forest restoration can deliver both climate and ecological benefits by removing carbon while bringing degraded Amazonian landscapes back toward native forest ecosystems. Mombak expects to issue another 55,000 carbon removal credits by the end of 2026, while the Symbiosis Coalition—which includes major corporate buyers such as Google and Microsoft—has committed to contracting more than 20 million tonnes of nature-based carbon removals by 2030. However, experts and critics stress that carbon credits should complement—not replace—direct reductions in corporate greenhouse-gas emissions. The challenge for the carbon market remains ensuring that every credit represents measurable, additional and durable carbon removal, alongside genuine biodiversity and ecosystem benefits. More
