Audit Analysis
Karbonetiq Contrecoeur is a carbonated-materials CDR project in Quebec verified by 350Solutions under the Puro.earth registry. Additionality is confirmed via a combined test and the inherent permanence of mineralized carbon is strong, but several MRV parameters (leakage, FNRB, usage rate) are absent from the available record, and the project-specific baseline adds moderate uncertainty. The verification report is recent and the ERR figures match exactly, but the documentation set is limited to two documents.
Red Flags
- Leakage deduction and justification are not stated in any available document, leaving the treatment of displaced emissions unverified.
- No buffer pool percentage is specified, and while reversal risk is inherently low for carbonated materials, the absence of a formal buffer mechanism is a gap.
- FNRB method and value are not stated, making it impossible to assess whether the carbonation efficiency assumption is conservative.
- Four corrective actions remain open, including installation of a water meter and compilation of a dedicated stakeholder engagement document.
