Rigorous protocolsyou can trust.
Isometric protocols are authored by our team of Ph.D. scientists, and set the bar for what suppliers need to measure to demonstrate that carbon dioxide has been removed from the atmosphere and safely stored. In line with the Isometric Standard, all protocols ensure removals are additional and based on the latest scientific knowledge.Each protocol is modular, ensuring suppliers can choose the capture, feedstocks, LCA, and storage mechanisms that best describe their process while adhering to our uniformly high and conservative standard.

Ocean Alkalinity Enhancement (OAE) enhances the natural capacity of the ocean to absorb and store carbon. The process works by adding alkaline materials to seawater, which acts to raise pH and shift the surface ocean’s carbonate buffer system to consist of proportionally more bicarbonate and carbonate ions and less dissolved aqueous carbon dioxide. This change prompts drawdown of atmospheric carbon dioxide into the surface ocean, lowering the concentration of atmospheric carbon dioxide.

OAE modules
Modules are distinct parts of Isometric's protocols, each detailing a portion of a project's carbon removal. This modular structure makes it simple to quickly adjust protocols to appropriately describe the removal mechanism while maintaining their rigour and quality.
v1.0 | CertifiedDissolved Inorganic Carbon Storage in Oceans
This module details the durability, reversal risks and requirements for storage of removed atmospheric CO₂ as dissolved inorganic carbon (DIC) in the ocean by CDR approaches.
Storage Module
v1.0 | CertifiedAir-Sea CO₂ Uptake
This module details the monitoring requirements for air-sea gas exchange in oceans.
Capture & Conversion Module
v1.0 | CertifiedRock and Mineral Feedstock Characterization
This module details the key physical and geochemical characteristic requirements of rock and mineral feedstocks for CDR projects to ensure safety and suitability for carbon removal.
Feedstocks Module
The Isometric Science Team consists of internal, full-time scientists, all of whom are subject matter experts in one or more CDR pathways. The scientists developing our OAE protocols have combined expertise in marine chemistry and carbon dynamics.
We collaborate both internally and externally to conduct foundational research, evaluate and develop protocols and communicate the applications of our work.
