Audit Analysis
ART Line T4 in Yibin is a VCS transport energy-efficiency project (ACM0016 v6.1) with VVB-confirmed additionality and no inherent permanence risk, but it suffers from significant documentation gaps: no monitoring period is stated, usage monitoring methods are absent, and the leakage treatment is contradictory between the PDD and the validation report. The identical claimed and verified ERR figures (33,477) suggest no independent monitoring data has been extracted, limiting confidence in the credit volume.
Red Flags
- Leakage justification is contradictory: the validation report (2025-09-30) states it is 'quantified' while the PDD states it is 'not addressed'; a 0% deduction with inconsistent documentation weakens the leakage claim
- No monitoring period is stated in any available document, making it impossible to determine whether the 33,477 tCO₂e ERR covers the full 7-year crediting period or a single reporting interval
- Usage monitoring method, assumed usage rate, and verified usage rate are all absent from the extracted record, leaving the core activity-level assumptions unverified
- Low extraction confidence across the document set indicates at least one key document was poorly readable, reducing reliability of the extracted facts
