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.

Biomass Carbon Removal and Storage (BiCRS) involves storing carbon present in biomass, which is organic material originating from living or recently living organisms. Examples of products stored are biomass in its original form, dried biomass, or products produced from biomass such as bio-oil or biochar.

BiCRS 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 BiCRS protocols have deep knowledge of geologic storage of carbon and geochemical tracing, and other aspects of MRV necessary for verification of BiCRS projects.
We collaborate both internally and externally to conduct foundational research, evaluate and develop protocols and communicate the applications of our work.
