Anlu Aonong Swine Farm Manure Management System GHG Mitigation Project

Audit Analysis

A VCS biogas-from-swine-manure project in China with VVB-confirmed additionality and no inherent permanence risk, but significant concerns arise from a project-specific baseline, a four-fold contradiction on leakage treatment, and verified emissions reductions that represent only about 15% of the pro-rata ex-ante expectation for the elapsed monitoring period. Multiple material findings and corrective actions remain open, and key eligibility fields (CORSIA, CCP) are unconfirmed.

Project Description

Red Flags

• ⚠Verified ERR of 45,992 tCO2e for the 2021–2023 monitoring period represents only ~15% of the pro-rata expectation (~307,000 tCO2e) derived from the PDD's lifetime estimate of 982,968 tCO2e, suggesting the ex-ante baseline or activity assumptions were substantially overstated.
• ⚠Leakage treatment is contradictory: the verification report (Oct 2025) states leakage was quantified, while the validation report (Dec 2023) records it as not addressed; no leakage deduction percentage is provided in either document.
• ⚠FPIC status is contradictory: the verification report confirms FPIC was conducted, but the monitoring report (Sep 2025) records it as not conducted.
• ⚠Two material findings remain open with corrective actions required: missing SD-contribution evidence and insufficient stakeholder interview detail.
