CDR Verification Framework
This is an interactive tool for understanding Verification Confidence Levels (VCLs) for carbon dioxide removal (CDR) by mapping key uncertainties for different CDR pathways. Developed in collaboration between CarbonPlan and Frontier. Read the explainer article, the Frontier post, or methods for more detail.

Biomass Carbon Removal and Storage
v1.0
VCL
3-5
Biomass with carbon removal and storage (BiCRS) uses photosynthesis to remove CO₂ from the atmosphere, and transforms the resulting biomass (e.g. via pyrolysis) and its environment (e.g. via geologic injection) to achieve long-term storage. This pathway is VCL 3-5, meaning that current quantification capacity can establish permanent carbon removal, but that for certain approaches, significant uncertainties remain.
