Audit Analysis
A VCS-registered geothermal space-heating project in China with VVB-confirmed investment additionality and no reversal events, but burdened by 13 material findings, two inter-document contradictions, and a project-specific baseline. The project delivered roughly 71% of its pro-rata expected emissions reductions for the elapsed monitoring period, indicating conservative crediting. Documentation quality is the weakest dimension, with numerous PDMR gaps and formula errors requiring corrective action.
Red Flags
- 13 material findings in the verification report, including inconsistent project boundary for fugitive geothermal emissions, unassessed baseline scenario values, and missing IRR benchmark assessment
- Contradiction between the PDD (leakage 'deemed negligible') and the monitoring report (leakage 'quantified') creates ambiguity in the leakage treatment
- Contradiction between the PDD (additionality 'combined' test) and the validation report (additionality 'investment' test) undermines clarity of the additionality basis
- 13 corrective actions remain open, including missing KML files, formula typos, and absent audit-history entries
