Analysis

A CAR-registered dairy digester methane capture project with VVB-confirmed additionality and a standardized methodology, but the verification report records 12 material findings including over-reporting in three vintage years and repeated QA/QC calibration failures. Leakage treatment and several key MRV parameters are absent from the available documents, and the project-specific baseline has no documented reassessment date. The project is valid but carries meaningful data-quality and transparency concerns.
