WWF Biogas Nepal II

Audit Analysis

WWF Biogas Nepal II is a Gold Standard biogas project with a confirmed barrier-based additionality test and a quantified 5% leakage deduction, but it relies on a project-specific baseline and lacks a stated buffer pool. The project over-delivers relative to its ex-ante estimate (approximately 220% of the pro-rata expectation for the monitoring period), which is a positive signal for claim safety. Multiple contradictions across documents—particularly in the ex-ante lifetime ERR, additionality verification status, and crediting period dates—introduce moderate data-reliability concerns.

Project Description

Red Flags

• ⚠Additionality was marked as not verified in the 2022 verification report but confirmed in the 2025 report; the earlier negative finding is unexplained in the extracted record.
• ⚠The ex-ante lifetime ERR differs by a factor of ~3.6 between the 2014 appendix (691,591 tCO₂e) and the 2025 monitoring report (193,565 tCO₂e), with no documented reconciliation.
• ⚠Crediting period dates differ between the 2022 and 2025 verification reports (2017-07-24 to 2024-07-23 vs 2017-04-30 to 2023-03-31), suggesting a possible period correction or extension that is not clearly documented.
