Terradot Collaborates with Microsoft to Boost Carbon Removal through Enhanced Rock Weathering

Terradot, a climate tech startup, has signed a major deal with Microsoft to remove 12,000 tons of carbon dioxide from the atmosphere between 2026 and 2029.

This deal not only contributes to carbon reduction but also enables Terradot to carry out the most extensive scientific monitoring yet seen at a commercial Enhanced Rock Weathering (ERW) site, exceeding current industry verification standards.

Backed by Microsoft, Terradot has launched its advanced research initiative in Brazil, where it is expanding its commercial operations and anticipates issuing its first carbon credits by the end of 2025.

Building Momentum with Major Backing

This collaboration follows Terradot’s successful $54 million Series A funding round, which included investment from Microsoft’s Climate Innovation Fund. It also builds on nearly 300,000 tonnes of carbon removal commitments Terradot secured in late 2024 through deals with Google and Frontier.

James Kanoff, CEO of Terradot, said, “"This agreement with Microsoft represents a critical step forward in our mission to transform Enhanced Rock Weathering into a cornerstone of global carbon removal efforts.”

He added, “Beyond purchasing carbon removal credits, Microsoft is investing in the scientific research needed to build confidence in ERW and dramatically improve the accuracy of measurement, reporting, and verification.”

Pioneering Research to Validate and Scale ERW

The partnership’s research initiative has two main goals: to bolster scientific trust in ERW as an effective carbon removal strategy and to develop more affordable, scalable measurement methods for future projects.

Current verification frameworks provide a basic foundation for ERW, but Terradot’s expanded research will go much further. Through dense sampling strategies and sophisticated watershed and water system monitoring, the project aims to refine carbon cycle models and improve verification accuracy.

Terradot is rapidly growing its operations in Brazil, having secured over 300,000 tons in carbon removal commitments. To date, the firm has placed almost 50,000 tons of rock onto 2,000 hectares of agricultural land.

The closeness of rock quarries, within 50 kilometers of agricultural land, reduces logistical cost and complexity.

Furthermore, Brazil’s tropical climate, featuring warm temperatures and ample rainfall, accelerates the rock weathering process, making it an ideal environment for ERW deployment. Terradot's initiatives in Brazil are expected to produce their initial carbon credits by the end of 2025.
