Terradot

The Approach

Terradot sources basalt from quarries across southern Brazil, transports it to nearby farms where it is spread on farmland to absorb CO2, and measures how much CO2 has been removed. The basalt reacts with rainwater, converting atmospheric CO2 into bicarbonate, which is stored permanently in the ocean.

Terradot conducts soil sampling both before and after application to quantify the amount of CO2 captured. This approach also helps farmers with soil health and pH management.

The Case for Terradot

Brazil is an ideal venue for enhanced weathering. The country’s warm, humid climate, and well-drained clay and sandy soils create optimal conditions for accelerated rock weathering. Brazil also benefits from an abundance of basalt quarries located near farms, strong farmer interest in using basalt rock application to improve degraded soils, and government incentives promoting soil restoration.

Terradot’s partnership with the Brazilian government’s principal agricultural research agency (EMBRAPA) creates potential for scale. Joint pilots and research projects with EMBRAPA will give Terradot access to 1+ million hectares of land. This collaboration will also help earn farmers’ trust.

Terradot has a feasible path to near-term, low-cost removal. Terradot projects a 35% decrease in the cost of removal by 2030 driven by: recruitment of farmer partners closer to quarries, development of new MRV methods that rely on fewer samples, and deployment of a software platform to optimize spreading and sampling.

Despite being a young company, Terradot is showing promising early results. Terradot has only been operating in Brazil since 2023, but has already demonstrated its ability to run scaled-up operations, spreading more than 48,000 tons of rock in its first year over 1,800 hectares of agricultural land.

Pricing and Delivery

Frontier buyers’ total offtake is $27M to deliver 90,000 tons between 2025 and 2029. The price accounts for both the removal itself as well as measuring, reporting and verifying (MRV) that each ton is safely and permanently stored.
