Audit Analysis

The BT3 Windfarm is a Gold Standard wind energy project in Vietnam with a VVB-confirmed investment additionality test and a jurisdictional grid-emission-factor baseline, both appropriate for the sector. However, four material findings (methodology version mismatches, a missing calibration hyperlink, and an emission-factor misalignment) and a low extraction confidence across the document set introduce meaningful uncertainty. The project delivered roughly 87% of its pro-rata expected reductions for the elapsed monitoring period, consistent with normal wind variability.

Red Flags

  • Four material findings (CARs) in the verification report: methodology version number errors on the cover page and in MR sections, a missing calibration-frequency hyperlink, and a combined margin emission-factor value that did not align with the PDD
  • Minimum extraction confidence rated 'low', indicating at least one key document was poorly readable, reducing reliability of the extracted record
  • Reversal events are listed as 'not addressed' in the extracted record, and no buffer pool percentage is stated, leaving permanence risk unquantified
  • Five contradictions between the PDD, validation report, and verification report (FPIC status, additionality test type, ERR figures, baseline method, leakage treatment) create ambiguity about the project's true parameters
