Royal Dairy Solid Separation Enhanced by Vermicomposting

Audit Analysis

The Royal Dairy Solid Separation project has a VVB-confirmed barrier additionality test and no reported reversal events, but suffers from a project-specific baseline, an unaddressed 0% leakage deduction, and no stated buffer pool. Eleven corrective action requests during verification indicate significant initial data-quality gaps, though all were resolved. The project delivered exactly its claimed emissions reductions for the 2024 monitoring period, but the absence of a lifetime ex-ante estimate prevents a full over-crediting assessment.

Project Description

Red Flags

• ⚠Leakage deduction of 0% with justification listed as 'not addressed' in the 2025 verification report, despite the 2024 report having stated it was 'quantified' — a regression in documentation quality
• ⚠No buffer pool percentage stated for a manure-management project with inherent reversal risk (degradation of vermicompost or re-methanation)
• ⚠Eleven corrective action requests raised during the 2025 verification cycle, including discrepancies in herd counts, missing fossil-fuel calculations, and parameter deviations, indicating fragile data management
• ⚠Baseline is project-specific with no documented reassessment date, and the 2025 monitoring report describes the baseline as 'mixed' (measured and modeled) while an earlier 2025 report described it as purely 'modeled'
