Hengyang New Hope Swine Farm AWMS GHG Mitigation project

Audit Analysis

A VCS-registered anaerobic waste management project at a Chinese swine farm with a VVB-confirmed investment additionality test and established methodology (ACM0010 v08.0), but significant gaps in permanence treatment, a weakly justified 0% leakage deduction, and no monitoring data available to verify ex-ante claims. The validation report identified and resolved eight material findings, but the project-specific modeled baseline and absence of a buffer pool leave moderate residual risk.

Project Description

Red Flags

• ⚠Eight material findings and eight corrective actions were raised during validation, including an incorrectly applied MCF value (dry vs. moist), incomplete N2O emission calculations, and an unjustified LEstorage=0 assumption for the full project life
• ⚠Leakage deduction is 0% with a 'deemed negligible' justification, yet the PDD (June 2025) initially described leakage as 'quantified' — the contradiction is unresolved in the record
• ⚠Reversal/permanence risk is explicitly 'not addressed' and no buffer pool percentage is stated, despite a 10-year crediting period
• ⚠No monitoring report or monitoring period data is available; the project has been in its crediting period since January 2023 but only validation-stage data exists
• ⚠Minimum extraction confidence is rated 'low', indicating at least one key document was poorly readable
