BINZHOU TOPIGS NORSVIN BREEDING SWINE CO., LTD. BINHAI SWINE FARM BIOGAS RECOVERY AND UTILIZATION PROJECT

Audit Analysis

A VCS biogas recovery project at a Chinese swine farm with a VVB-confirmed barrier additionality test and appropriate safeguards, but undermined by a material finding that the biogas heating system was never operational (all biogas flared), multiple unresolved monitoring data gaps, and verified emissions roughly 39% below the pro-rata expectation for the elapsed crediting period. The project's climate benefit is real but the deviation from the project design and the thin leakage justification warrant caution.

Project Description

Red Flags

• ⚠Biogas heating system was never put into operation during the monitoring period; all biogas was flared instead of used for heat as described in the Project Design Document (verification report, 2023-09-08).
• ⚠Verified emissions of 20,326 tCO2e represent only ~61% of the pro-rata expectation (~33,420 tCO2e) derived from the PDD lifetime estimate of 82,563 tCO2e over the 34-month monitoring window, indicating a significant under-delivery relative to the ex-ante baseline.
• ⚠Four corrective actions remain open, including missing thermocouple readings, missing FRG monitoring values, and missing swine weight sampling results (verification report, 2023-09-08).
• ⚠Leakage deduction is 0% with only a 'deemed negligible' justification; no quantitative analysis of potential methane slip or unaccounted emissions is provided in the available documents.
