Carbon Removal Credits

Our system combines Biomass Sinking, safely storing carbon in the deep ocean for centuries, and Ocean Alkalinity Enhancement, transforming atmospheric CO2 into stable dissolved inorganic carbon, where it remains for centuries to millennia.​

Running Tide is the global leader in open-system monitoring, reporting, and verification. We have spent the last six years building the technology (hardware and software) required to monitor the flow of carbon through open/natural systems while integrating and improving on the best available science and building out independent 3rd party validation and verification.​

Our carbon removal work has been validated by Deloitte for alignment with ISO and similar international standards. We are working diligently toward conformance with the  Reykjavik Protocol, and our carbon removal projects are subject to assurance and third party review by accredited, internationally-recognized auditing firms.
