An inside look at why InPlanet is getting the most of Enhanced Rock Weathering through farms in Brazil
It was on a road trip through the vast farmlands of Brazil that InPlanet’s COO Niklas Kluger and CEO Felix Harteneck first had the vision of founding InPlanet. Niklas had studied various carbon removal techniques during his master’s and gained hands-on agricultural experience in agroforestry, reforestation, and soil restoration while working with farmers in Brazil. Enhanced Rock Weathering in Brazil attracted his interest due to the outstanding co-benefits and conditions in the country. At the same time, Felix understood the appealing economics behind the technology and saw that Enhanced Rock Weathering (ERW) could be scalable and, therefore, valuable to our planet. Collectively, they were inspired by its potential to revolutionize sustainable agriculture and combat climate change. They decided to found InPlanet and set up the first ERW enterprise in Brazil in August 2022.
These are some of the many reasons why Enhanced Rock Weathering in Brazil is a particularly promising activity to scale Enhanced Rock Weathering for Carbon Dioxide Removal (CDR), while having profound agricultural benefits.
The Climate
There are two main climatic factors that significantly accelerate carbon dioxide removal through rock weathering: rain and heat. Abundant rainfall is crucial, as dissolving minerals requires water. Additionally, warm temperatures speed up the rate of dissolution, leading to faster carbon dioxide removal.
Therefore, Brazil’s climate creates the perfect environment for EW, with weathering rates more than ten times higher than temperate regions like Europe or the USA. The maps below show how Brazil is a sweet spot, with a high mean annual temperatures and rainfall.


Scalability
Land availability
One of the main advantages of Enhanced Rock Weathering compared to other carbon removal technologies is that it requires no additional land use. We apply rock powder directly on existing agricultural farmlands – and this is where Brazil stands out.
Remember our founders’ trip through the Brazilian countryside? If you have the opportunity to explore Brazil beyond the main cities like São Paulo and Rio, you will see that you may travel for hours admiring the vast greenery of soybean, sugarcane, coffee, and other crops. This abundance of farmland, covering 33% of the country’s territory, provides massive opportunities for scaling ERW.
Brazil ranks among the top five agricultural producers in the world with an agricultural land area almost twice what is available in the whole of Europe, presenting huge potential for InPlanet to scale up its ERW projects.

Rock Powder available
In addition to expansive farmlands to apply our products, high-quality rock powder is the key component to implement and expand ERW projects.
Brazil’s robust mining and quarrying sectors provide abundant amounts of feedstock, which is produced as a by-product of their operations. InPlanet repurposes this rock powder for carbon removal, contributing to a circular economy.
The best part is that Brazil has a large mining industry that will be able to provide large amounts of feedstock to scale ERW and meaningfully contribute to climate mitigation targets by 2050.
This means that, in Brazil, we do not need to establish new mines for rock powder; as we have rock powder already available in a network of mines around the country, with millions of tonnes already in stock.
The combination of ample land for application and abundant rock powder resources make our work in Brazil exceptionally scalable, presenting unparalleled opportunities for impactful carbon dioxide removal efforts.
Pioneering research and legal framework for Enhanced Rock Weathering
Brazil pioneered academic research that explores the benefits of rock powder since the 1950s. A movement of scientists called Rochagem (“rockage”) has been studying and promoting the use of natural rock powder fertilizers (referred to as ‘remineralizers’) since then. Brazil has also hosted five international conferences on rock powders in 2022 and has a unique collaborative industry voice through the Brazilian Association of Producers of Soil Remineralizers and Natural Fertilizers (ABREFEN).The result of efforts by the rochagem community was a legal framework for the exclusive certification of rock powders in agriculture (‘remineralizers’), which goes beyond the incorporation of rock powders into generic amendment regulations seen elsewhere.
Co-benefits where they are most needed
Tropical soils have been significantly depleted of nutrients due to enduring intense weathering conditions for millions of years. Consequently, extensive fertilizer application has become increasingly common, affecting soils’ acidity and requiring even more chemical feedstock to raise the pH – a practice that comes with a high financial and environmental price.
Moreover, chemical fertilizers can contribute to the loss of minerals in the soil, making farms more dependent on even higher fertilizer applications, which creates a vicious cycle of increasing fertilizer use and soil degradation. Rock powder is treating the source of the problem, naturally releasing minerals in the soils and restoring the health of the land.
It is essential to note that Brazil feeds some 10% of the world’s population. Restoring the health of soils in Brazil means improving the nutritional quality of the produce that will be exported worldwide. Therefore, addressing soil degradation in tropical regions is not only crucial for local agriculture but also for global food security.
Enhanced Rock Weathering in Brazil’s potential to offset
Through extensive research and analysis tailored to Brazil’s unique conditions, InPlanet’s scientists determined that ERW has the potential to offset 100% of Brazil’s Nationally Determined Contributions. Whilst the world continues in an effort to reduce emissions, scaling Enhanced Rock Weathering globally can potentially contribute to removing an extra 0.5–4 Gt of CO2, accounting for between ~20 and 100% of global Carbon Removal requirements by 2050.
Conclusion
In this context, Brazil emerges as a global leader in Enhanced Rock Weathering, making the country an attractive environment for the Carbon Removal Market. The synergy between the country’s natural climate, potential for scalability, and regulatory framework available offers an unprecedented opportunity to substantially reduce atmospheric CO2 levels.
InPlanet continues to scale its operations around the tropics and has a team of dedicated people all around the world, from the US to China, Europe, the Caribean, and, of course, Brazil, joined in the mission of creating a livable planet for us and for future generations. We are bringing the world together to solve this global crisis. You can be part of this mission to harness the power of Enhanced Rock Weathering and contribute to a greener, healthier planet.
