ICVCM approves five new Isometric protocols to use CCP label

World’s first CCP-labeled credits across three pathways

Today, five new Isometric carbon removal protocols received approval from the Integrity Council for the Voluntary Carbon Market (ICVCM) to issue credits with the Core Carbon Principles (CCP) label. Isometric is the first and only carbon registry to receive ICVCM approval for protocols in these pathways. 

The approved protocols are Biomass Geological Storage (v1.0-1.1), Bio-oil Geological Storage (v1.0-1.1), Subsurface Biomass Carbon Removal and Storage (v1.0), Biogenic Carbon Capture and Storage (v1.1), and Direct Air Capture (v1.1). 

This brings the total number of Isometric protocols with ICVCM approval to six, following the approval of the Biochar Production and Storage Protocol (v1.0) in August, cementing our position as the world’s leading carbon removal registry.

ICVCM’s decision follows a rigorous, independent assessment confirming that these five protocols meet all ten CCPs, including permanence, additionality, transparency, independent verification, and robust quantification.

From today, all credits issued under these protocols are eligible for the CCP label, with all previously issued credits also receiving it retroactively—making them the world’s first credits in their respective pathways to carry the CCP label. These include:

  • 3,655 Bio-oil Geological Storage credits issued to Charm Industrial
  • 55 Bio-oil Geological Storage credits issued to NULIFE GreenTech
  • 25,215 Biomass Geological Storage credits issued to Vaulted Deep
  • 4,095 Subsurface Biomass Carbon Removal and Storage credits issued to Graphyte
