To reach the gigatonne-scale carbon removal the world needs to keep warming below 1.5°C, we need more than science. We need finance that can scale.
An industry first, this novel financing structure from Inlandsis provides the capital needed to fully deliver on this purchase, with the scope to scale further high-integrity ERW projects globally.
Jim Mann, UNDO’s Founder and CEO, puts it simply:
“Innovative financing is the catalyst for unlocking gigatonne-scale carbon removal. The support of Inlandsis shows how financial backers can help transform carbon removal into a genuine asset class, one that is scalable, tradable, and investable. By combining financial innovation, strategic partnerships and bleeding-edge science, UNDO is accelerating deployment and delivering both climate and agricultural benefits in Ontario and beyond.”
A Measured Progression With Microsoft
This relationship has grown season by season. In 2023, Microsoft made its first-ever ERW purchase with a 5,000 tonne contract. In 2024, Microsoft followed with 15,000 tonnes and funding for vital science. Today’s agreement for 28,900 tonnes is the biggest yet. That progression matters because it reflects evidence-led growth, increased confidence in ERW, and trust in delivery that holds up to scrutiny.
Phillip Goodman, Director, Carbon Removal Portfolio at Microsoft, explains the rationale:
“Enhanced rock weathering is a promising pathway to gigatonne-scale carbon removal. UNDO’s commitment to scientific rigour gives us confidence in both the durability of these credits and their role in helping Microsoft achieve its goal of being carbon negative by 2030.”
Financing Designed for Delivery
For Inlandsis, this marks key firsts: their first investment in an ERW project, and the first Canadian investment for their second fund. It is a signal that climate finance is moving toward structures that can support durable removals with clear evidence chains.
As David Moffat, Managing Director at Inlandsis, notes:
“Inlandsis is very pleased to provide capital to this strategic and innovative deal, helping to strengthen the growing relationship between Microsoft and UNDO while advancing the critical fight against climate change. This collaboration marks several milestones for us and highlights our commitment to advancing carbon finance across Canada and beyond.”
As with the recent Barclays deal, this purchase is underwritten by CFC, a specialist insurance provider that supports high-quality carbon market initiatives by mitigating risk and enabling transactions.
Insurance is fast becoming a critical enabler for climate solutions such as ERW. It provides both banks and investors with the confidence that projects will deliver, unlocking more capital for scaling operations.
What This Signals for the Market
Buyers want permanence, additionality, and verification. Lenders want clear milestones and repayment that is tied to paid issuance. Farmers want predictable, well-run operations that fit within crop calendars. This structure meets those needs. It turns expected tonnes into delivered tonnes by making capital follow fieldwork and by making issuance follow evidence. It is also repeatable. The same draw and repay logic can scale to larger volumes and additional regions as the operational base grows.
The direction of travel is clear. With backing from leading brands such as Barclays, British Airways, and McLaren, UNDO is building the operating and scientific foundation to spread mineral-rich silicate rock at a massive scale in the years ahead, with a focus on transparent MRV and practical delivery.
Under this agreement, 90,000 tonnes of wollastonite will be spread, benefiting 30,000 acres of Canadian farmland. Deployment supports farm operations with familiar equipment and schedules, and it is set up to report progress with transparency as seasons advance.
Operations are practical, seasonal, and measured. Delivery is planned with farms to fit planting and harvest alongside local conditions. Material quality is checked, spreading equipment is calibrated to target rates, and GPS logging records where and when applications occur. After application, field teams collect porewater and soil samples at defined locations and intervals, then move samples through validated lab workflows with a full chain of custody.
The operational record connects load tickets, GPS traces, and lab results, creating a clear evidence chain from quarry to field to credit. The aim is delivery that is repeatable across sites and seasons, with data that stand up to scrutiny, and accounting that stays conservative as volumes grow.
Enhanced rock weathering accelerates a natural process where CO₂ in rainwater reacts with silicate minerals, and the chemistry that follows leads to storage on geological timescales. Turning that pathway into verified credits requires measurement by design. Sampling plans are written in advance for statistical power, include controls, and specify when and where porewater and soils are analysed. Laboratory workflows are auditable, results pass quality checks, and every measurement is tied to time, location, and method.
Accounting is conservative. Life cycle emissions for quarrying, processing, logistics, and MRV are deducted, and uncertainty is applied as a discount. Issuance follows delivery and verification, which means credits represent net, measured removal rather than a forecast. Reporting is shared on a schedule so partners can see progress and understand results.
How Partners Make This Work
Strong partners make scaling possible. Microsoft’s multi-year purchasing provides demand you can plan against. Inlandsis’s delivery-aligned facility provides capital that tracks the work. UNDO’s teams and local partners run the operations, sampling, and lab workflows with a focus on data integrity. The combination is what turns carbon removal into a genuine asset class, one that can be financed, evaluated, and grown with confidence season after season.
From Agreement to Delivery
The next phase is steady execution. That means planning rock supply and spreading across active sites, keeping measurement programs in lockstep with operations, and sharing updates with transparency so partners can follow the data.
The combination of Microsoft’s long term purchasing, Inlandsis’s facility, CFC’s derisking, and UNDO’s on the ground delivery provides a strong foundation for that work. As volumes grow, the focus remains the same, deliver permanent, measured carbon removal with benefits for soils and farming communities.
