Portfolio Spotlight: Inplanet
This series highlights the many companies Carbon Drawdown Initiative has invested in.
NVIDIA, Duolingo, and InPlanet
Fast Company’s “Most Innovative Companies in Latin America for 2025” brought attention to a company using regenerative agriculture to remove carbon from the atmosphere. In other words, while other innovative companies create next-generation microchips or augment language learning software, InPlanet is spreading rock dust.
The founders’ (Felix Harteneck and Niklas Kluger) mission is simple and visionary: Use enhanced rock weathering (EW) to trap carbon in tropical soils—turning farmland into climate tech.
The early results show a simple and rewarding finding: it’s working.
Project Serra da Mantiqueira
InPlanet’s project, called Serra da Mantiqueira, delivered the world’s first independently verified enhanced rock weathering (ERW) carbon removal credits. The initiative partners directly with local farmers to restore soil health and transition toward sustainable agriculture.
Brazil offers ideal conditions for scalable carbon removal due to abundant basalt resources and favorable tropical climate. The country's consistently high temperatures and heavy rainfall significantly accelerate the carbon sequestration process, making ERW notably more efficient compared to temperate regions. Additionally, Brazil’s extensive agricultural and pasture lands—nearly 40% of its total area—more than double the European Union's approximately 157 million hectares.
The team at InPlanet sources basalt rock powder from Brazilian mines and quarries, where it would otherwise accumulate as waste. After rigorous quality control, this basalt powder is distributed to local farms as a sustainable alternative to traditional fertilizers. This method not only captures carbon but also directly enhances soil health, boosts crop yields, and promotes a sustainable future for agriculture.
InPlanet will have spread enough rock powder in the next two years to achieve a CO₂ removal of 1 million tonnes, and their long-term vision is even bolder. They are working toward removing gigatons of CO₂ while regenerating tropical soils, proving that ERW is both an effective and sustainable solution to the present climate issues.
ERW Credits
InPlanet is on pace to spread 200 kilotons of basalt early this year, building on methods they have proven through rigorous research, cutting-edge geochemical tracing, and third-party testing. As a result of their dedication to excellence, the team delivered the first Enhanced Rock Weathering credits in the world.
Isometric, a carbon removal registry, issues credits verified according to their Isometric Standard, which lists the requirements to prove carbon capture and storage have measurable climate impact.
Put simply, they verify what works.
The Serra da Mantiqueiera project has earned InPlanet over 235 Isometric credits, meaning they’ve successfully removed 235 net tonnes of carbon dioxide from the atmosphere in a little over a year of testing. Their work has global implications. As the science continues to advance, InPlanet will lead the charge to scale ERW and heal our planet.
