Jinquan Geothermal Based Space Heating System

Audit Analysis

The Jinquan geothermal space-heating project (VCS-3101) demonstrates a sound additionality case confirmed by TÜV Rheinland via a combined test, and the first monitoring period delivered 65,568 tCO₂e consistent with the claimed figure. However, the project-specific baseline, absence of a stated buffer pool, inconsistent leakage-justification language across documents, and a set of eight corrective actions (all closed) temper confidence. Several key MRV parameters (FNRB, usage rates, end-use tracking) are not stated in the extracted record, limiting full verification of the credit quantity.

Project Description

Red Flags

• ⚠Leakage justification is characterised as 'quantified' in the monitoring report but 'deemed negligible' in the validation report, with a 0% deduction in both — the basis for the zero deduction is not transparently documented.
• ⚠No buffer pool percentage is stated in any available document, leaving the permanence safeguard unquantified despite the project being an avoidance-type credit.
• ⚠Eight corrective actions were required during validation (missing equipment references, incorrect crediting dates, incomplete project-boundary assessment, calculation errors in Section 5.2, etc.), all closed but indicative of initial documentation quality issues.
• ⚠FPIC was not conducted and stakeholder-consultation documentation was flagged as unclear in the validation report's material findings.
