UNDO

This award recognises UNDO for accelerating the natural carbon cycle at industrial scale through enhanced rock weathering. In 2025, the company released a peer‑reviewed study in Frontiers in Climate providing field‑based evidence of measurable CO₂ removal under temperate conditions, secured a landmark offtake with Barclays for 6,538 tonnes of removal, signed a third agreement with Microsoft totalling nearly 49,000 tonnes, and won the prestigious XPRIZE Carbon Removal Award for its Canadian project.

By spreading crushed silicate rock across farmland, UNDO permanently locks away atmospheric CO₂ while simultaneously enriching soil health and increasing crop yields. More than a series of commercial milestones, UNDO has transformed enhanced weathering from a theoretical model into a verifiable, replicable carbon removal solution. The company’s rigorous measurement, reporting and verification framework, deployed across thousands of hectares, provides the credibility needed to attract corporate financing and government support. By proving that permanent carbon removal can be both nature‑based and scalable, UNDO has established itself as a global leader in the urgent race to build a net‑negative future.

For delivering enhanced rock weathering at verified scale and setting a credibility benchmark for the sector, UNDO receives this recognition.
