Grouped Projects For Laos Water Purifier

Audit Analysis

The Laos water purifier grouped project has a confirmed additionality test and quantified leakage deduction, but the verified emissions reduction of 134,200 tCO2e in a single 6-month monitoring period equals the entire 10-year lifetime estimate, representing a 20× over-delivery relative to pro-rata expectation. Ten contradictions across documents—including conflicting ERR figures, additionality test types, and fNRB methods—undermine confidence in the data. The project is not CORSIA-eligible and no reversal events were reported, but the over-crediting risk and project-specific baseline warrant caution.

Project Description

Red Flags

• ⚠Verified ERR of 134,200 tCO2e for the 6-month monitoring period (Jan–Jun 2025) equals the full 10-year lifetime estimate, implying a 20× over-delivery relative to the pro-rata expectation of ~6,710 tCO2e
• ⚠Ten contradictions across documents, including conflicting ERR figures (134,200 vs 84,968), additionality test type (investment vs barrier), fNRB method (not applicable vs national default), and crediting period start dates
• ⚠Buffer pool percentage not stated in any available document, leaving permanence risk unquantified
• ⚠Baseline is project-specific rather than jurisdictional, and no baseline reassessment date is recorded
