We do enhanced rock weathering
We’re harnessing the power of nature for a greener future. Our mission is to spread enough rock by 2025 to remove 1 million tonnes of CO2.
Taking action on CO2
Extreme weather. Soil degradation. Ocean acidification. Our climate is in crisis.
Reducing emissions alone isn’t enough. We need to remove excess CO2 from our atmosphere, permanently.

"Enhanced rock weathering represents the rare CDR pathway where permanence, scalability, and co-benefits intersect. We believe that with their proven carbon removal track record and emphasis on developing a trusted MRV methodology, Jim and the team at UNDO have what it takes to move the needle on negative emissions."
"Enhanced weathering offers a highly scalable, low-cost route to carbon removal, and the UNDO team is making strong progress. We're particularly excited about UNDO's upcoming large-scale field trials and commitment to working towards best-in-class measurement of removal, which will be essential to commercialising enhanced weathering."
"Enhanced rock weathering offers a great deal of potential, and we are excited by the prospect of having this nature-enabled approach as an additional pillar of our permanent carbon removal portfolio."
Global operations
Thousands of tonnes of rock spread in the UK, US, Australia and Canada, with field trials set up in East Africa.
