By 2050, we will need to remove between 5-10 billion tons of CO2 from the atmosphere every year (IPCC 2023). Oceanic Enhanced Weathering is the simplest and most scalable method we have to reach this goal and course correct our current climate trajectory.

OEW is a part of the geologic carbon cycle. We accelerate this cycle by grinding rocks into sand, adding the sand to the ocean, and monitoring the process to verify the resulting carbon removal.

Monitoring, reporting, and verification is one of the key challenges holding back deployment of ocean alkalinity enhancement carbon removal methods. Our novel tracer-based approach to MRV allows for environmental monitoring and the robust quantification of the amount of CDR performed without significant increases to the cost or complexity of the process.
