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, durable, 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.
Direct air capture refers to a set of chemical or electro-chemical processes that remove carbon dioxide from ambient air. CO₂ in the air binds to either a solid sorbent or a liquid solvent which then undergo a process called regeneration where they are treated to release captured CO₂. This typically creates a pure stream of CO₂ which can then be stored using a variety of storage techniques.

DAC 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.
DAC science experts
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 DAC protocols have deep knowledge of environmental geochemistry and geologic storage of carbon, among other topics.
We collaborate both internally and externally to conduct foundational research, evaluate and develop protocols and communicate the applications of our work.
