GS3428 - Biogas PoA Switzerland - VPA1

Audit Analysis

This Swiss biogas project (Gold Standard, TÜV NORD CERT verified) has a combined additionality test confirmed by the VVB and a measured project-specific baseline, but is undermined by a very large number of material findings and corrective actions, a contradiction in leakage treatment (10% vs 0%), a flip in additionality verification between the 2023 and 2024 reports, and the absence of a buffer pool. The primary extracted document is essentially empty (one page, zero words, titled 'Untitled Document'), which severely limits confidence in the data record.

Project Description

Red Flags

• ⚠Additionality verification flipped from not confirmed (2023 verification report) to confirmed (2024 verification report) — the 2023 report's negative finding is unexplained and raises questions about the robustness of the additionality claim.
• ⚠Leakage deduction contradicts between documents: 10% in the 2024 verification report versus 0% in the 2025 validation report, with the justification shifting from 'quantified' to 'deemed negligible'.
• ⚠FPIC (Free, Prior and Informed Consent) was not conducted, which is a significant safeguard gap for a community-facing biogas project.
• ⚠The primary extracted document contains zero words, one page, and is titled 'Untitled Document' — the data record is extremely thin and the medium extraction confidence compounds the risk of missing critical information.
