Corigin-1: BioChar Q3-25

Audit Analysis

Corigin-1 is an early-stage biochar carbon removal project under the Isometric Standard with a PDD and stakeholder consultation as its only available documents. While it demonstrates some positive elements (LCA, carbon content testing, feedstock sustainability documentation), it lacks VVB verification, a buffer pool, leakage treatment, and FPIC, and makes a 1000-year permanence claim without demonstrated reversal risk mitigation. The project is not yet in a state where credit quality can be robustly assessed.

Project Description

Red Flags

• ⚠FPIC explicitly not conducted, and no grievance mechanism is documented — a significant safeguards gap for a project claiming community benefit sharing
• ⚠1000-year permanence claim with no buffer pool percentage stated and no reversal events explicitly addressed
• ⚠No leakage deduction or justification provided despite biochar feedstock sourcing and end-use displacement being material leakage pathways
• ⚠No VVB identified and no verification report available — additionality test (combined) is unverified
• ⚠No ERR figures (claimed or verified) available, making over-crediting risk unassessable
