Our Scientific Leadership
InPlanet's science leadership team is composed of experts in geology, soil science, and environmental engineering. Their work is focused on optimizing ERW for maximum carbon removal and soil health benefits. With decades of combined experience, they are dedicated to advancing ERW as a scalable climate solution.
Understanding Enhanced Rock Weathering
InPlanet investigates many components in the measurement process to advance ERW in the tropics scientifically and operationally. InPlanet investigates many components in the measurement process to advance ERW in the tropics scientifically and operationally.
Natural Rock Weathering
As rain (H₂O) falls through the atmosphere, it absorbs CO₂ and forms carbonic acid (H₂CO₃).
This weak acid reacts with rock and soils, producing dissolved bicarbonate and, over longer timescales, stable carbonate minerals.
Scientists estimate natural weathering removes approximately 1 billion tonnes of CO₂ from the atmosphere each year.

Accelerating Nature with Enhanced Rock Weathering
Enhanced rock weathering (ERW) is a nature-based carbon dioxide removal technology that permanently locks away CO₂.This approach accelerates a natural geological process that has been happening for millions of years.
Brazil offers abundant farmland and basalt with ideal climate conditions
With Brazil’s unique conditions, InPlanet’s EW projects benefit from an ideal setting for scalable carbon removal. The country’s abundant basalt deposits allow for efficient, sustainable sourcing and transport, while its vast agricultural lands and tropical climate, with high temperatures and heavy rainfall, accelerate the carbon sequestration process compared to temperate regions. This favorable context makes EW more effective and also brings immediate benefits to farmers, such as enhancing soil health, increasing crop yields and reducing reliance on fertilizers, thereby supporting a sustainable and resilient agricultural future.

Quantifying Impact
To accurately assess our carbon removal and agricultural regeneration efforts, InPlanet prioritizes rigorous sampling methodologies, comprehensive measurements, and transparent uncertainty quantification to ensure the integrity and reliability of our impact.
Scientific Rigor in Sampling
Soil samples are collected (0-20cm) at baseline before the rock powder spreading and 9 months later using GIS-assisted paired sampling. This method allows direct evaluation of chemical and agronomical changes at individual sampling points, greatly reducing the noise introduced by heterogeneous field conditions.
Five-Pillar MRV Approach
Through our Five-Pillar MRV Approach, we investigate multiple components at different levels of complexity. While most of these setups are not required for carbon credit generation, they serve critical research purposes, advancing ERW in the tropics both operationally and scientifically.

Conservative Results, Radical Impact.
Translating theoretical geochemical principles into complex, open-system agricultural environments requires an adaptive, risk-mitigated approach to Measurement, Reporting, and Verification (MRV).Bincreasing our baseline sampling density and anchoring our data in peer-reviewed loss factors, InPlanet ensures that every single credit issued represents a true, permanent, and permanent climate benefit.
1 sample/ha
We collect maximum 1 sample per 1 hectare to make sure we capture the soil heterogeneity and can accurately estimate rock powder dissolution and loss terms.
2 methods
InPlanet always use 2 methods to mitigate uncertainty: quantifying the CDR using soil-based method and then validate the CDR using porewater-based flux estimation.

Raising the Bar of Enhanced Rock Weathering
InPlanet has partnered with Isometric to ensure the highest standards of certification for our enhanced rock weathering projects. We are proud to be among the first to certify ERW, setting a new benchmark for quality and transparency in carbon removal.
Project Araçari
Project Araçari marks InPlanet’s second Enhanced Rock Weathering (ERW) credit issuance under the Isometric Standard, and the world’s first verified ERW credits from citrus agriculture. Building on our inaugural credits in sugarcane last year, this issuance demonstrates ERW’s continued evolution as a durable carbon removal pathway with agronomic benefits for Brazilian farmers.

Project Serra da Mantiqueira
The Serra da Mantiqueira, derived from the Tupi language meaning "raindrop," stands as a symbol of natural abundance and cultural heritage in southeastern Brazil. Project Serra da Mantiqueira is a groundbreaking Enhanced Weathering initiative as the first third-party certified carbon credits by Isometric.
Creating real impact on Brazilian Farmlands
Our network includes Brazilian and global scientists, innovators, and ecosystem builders. Together, we advance Enhanced Rock Weathering and high-integrity carbon removal through collaboration, delivering science-driven impact and agronomic benefits to citrus farms.
Our commitment to scientific rigour and transparency translates into unmatched MRV science and industry-wide advancement
Our dedication to advancing ERW transcends carbon credit generation. We actively share our findings through peer-reviewed publications and collaborative research, fostering a global understanding of ERW's potential in tropical ecosystems and beyond.

InPlanet’s commitment to measurement and monitoring bolster the integrity of their enhanced rock weathering carbon removal credits, which will contribute to Microsoft’s goal to be carbon negative by 2030.
Director of Carbon Removal at Microsoft
These world-first Enhanced Weathering (EW) credits are a key step to scaling carbon removal. They bring an unprecedented level of scientific rigor to a pathway that has great potential, but which has lacked robust verification until now. The transparent data behind these credits shows that Isometric’s high quality, verified EW credits represent a tonne of carbon dioxide removed from the atmosphere and should be a key part of every CDR buyer’s portfolio.
