Permanent CO2 removal at scale in Latin America 



Why we remove CO2

Reducing carbon emissions is not enough to prevent the worst consequences of climate change.

In order to stay below 1.5 °C of global temperature rise, we need to remove from our atmosphere 1 billion tonnes of CO2 per year by 2030 and 10 billion tonnes per year by 2050.

We need to scale up solutions with the potential of delivering permanent CO2 removal at scale to meet these ambitious goals.

Solutions like enhanced rock weathering that go beyond carbon capture are particularly important. Silica  aims to improve the lives of  low-income agricultural comunities around Latin America by increasing crop yields and enabling them to capture value from the production and sales of carbon credits. 

Our approach

Unleashing the power of nature

How we remove CO2

Enhanced rock weathering accelerates the natural process through which silicate rocks capture carbon. 


When finely ground volcanic rocks are spread in croplands, its silicates reacts with CO2 dissolved in rainwater and CO2 in the soil. This creates carbonate minerals that are stable for tens of thousands of years. This approach fights climate change by reducing greenhouse gases while improving soil health and agriculture.


The amount of CO2 captured is monitored and measured  through thorough testing and analysis of the treated soil before and after the silicate rock dust is applied.  

Application sites are monitored and tested to measure carbon capture empirically

Maximum impact and transparency

Permanent, verified removals

Silica employs the highest quality monitoring, validation, and reporting standards for its CO2 removals.

Every carbon credit issued is backed up by independently-verified direct measurements from soil analyses.


Surplus material from silicate rock extraction and processing is gathered

The material is spread on agricultural land using existing equipment

High-quality verified carbon credits are issued


Impact beyond carbon capture

Uplifting farmers

Increased crop yields

Silicate rock regulates soil pH and provides a steady nutrient flow that can lead to higher crop yields.  It also decreases stress produced by droughts and creates plants that are more resilient to  pests.


Cost savings

Farming operations employing limestone to regulate soil pH can completely eliminate the procurement and application costs of this material.


Passive income

Fixed payment per hectare creates an additional income stream for farmers that can substantialy increase their operating profits.
