CO2 Utilization in Concrete – Removals & Reductions – CarbonCure – U.S & Canada Project #1
#1of 5 in Bolivia#433of 629 in Verra (VCS)
Audit Analysis
A CarbonCure CO2-utilization project under VCS methodology VM0043 with VVB-confirmed additionality and no material findings, but undermined by eight inter-document contradictions, a 0% leakage deduction with no stated justification, an unconfirmed buffer pool, and a striking country mismatch (registered in Bolivia but named 'U.S & Canada Project #1'). Data reliability is a significant concern that limits confidence in the credit figures.
Red Flags
- Country mismatch: project name references 'U.S & Canada' but registry country is Bolivia — either a data-extraction error or a registration anomaly requiring clarification
- Eight contradictions across documents, including conflicting FPIC, grievance mechanism, safeguards, and benefit-sharing statuses between two verification reports dated 2025-04-07 and 2025-06-06
- Leakage deduction of 0% with justification recorded as 'not_addressed' in the verification report, while the PDD states 'deemed_negligible' — inconsistent treatment
- Buffer pool percentage not stated in any available document, leaving permanence risk unquantified
- ERR figures conflict: PDD reports 8,147 tCO2 while the monitoring report and verification report report 14,443 tCO2, with no clear reconciliation
