Enhanced rock weathering (ERW) company Terradot has secured a new carbon dioxide removal (CDR) deal with Microsoft, under which Terradot will remove 12,000 tonnes of CO2 between 2026 and 2029.
The importance of this deal extends beyond the positive carbon removal effect, as this agreement will also enable Terradot to develop a science-based, comprehensive monitoring process for commercial-scale ERW that will surpass registry crediting requirements.
Through this effort, Terradot hopes to not only improve the credibility and trust in ERW as a reliable solution for the planet’s climate crisis but also to generate a more cost-effective and scalable measurement approach for future ERW deployments.
Commenting on this investment decision, Brian Marrs, senior director of energy & carbon removal at Microsoft, stated, “This deal advances Microsoft’s interest in exploring under what conditions Enhanced Rock Weathering can safely become a cost-effective, scalable source of high-quality carbon removal.”
“Improving soils—both through conservation practices and addition of alkaline rocks—has the potential to deliver real benefits to farmers in addition to the climate.”
The recent deal with Microsoft brings the total CDR sales of Terradot to over 300,000 tonnes of carbon removal.
Founded in December 2024, the company leveraged nearly $60 million in funding secured through Seed and Series A rounds to establish its presence in the carbon removal market.
Last year, Terradot secured a $27 million deal with Frontier buyers for the purchase of 90,000 tonnes of CDR, scheduled to be delivered between 2025 and 2029.

At that time, it also locked in a separate Frontier-facilitated agreement with Google for the removal of 200,000 tonnes of CO2 in 2029 and beyond.
Collaborating with EMBRAPA, Brazil’s largest agricultural research institution, Terradot launched pilot ERW operations in this South American country, managing to spread nearly 50,000 tonnes of rock across 2,000 hectares of Brazilian farmland so far.
Going forward, the company will work on expanding its operations in Brazil, with the first ERW carbon credit deliveries expected towards the end of 2025.
