Audit Analysis
The Brascarbon Methane Recovery Project is a VCS-registered waste-sector project using AMS III-D methodology with a VVB-confirmed investment additionality test, but it carries a notable number of material findings (seven) and corrective actions (eleven) that raise concerns about the robustness of its additionality demonstration, baseline modelling, and monitoring data quality. The absence of a buffer pool, a thin leakage justification, and multiple inter-document contradictions (particularly on additionality test type and baseline characterisation) temper an otherwise structurally sound project. Overall, the project is functional but sits in the middle of the quality range, with room for significant improvement in documentation consistency and methodological rigour.
Red Flags
- Seven material findings reported in the verification report, including an inconsistency in the additionality assessment between the V&V report and the PD&MR (regulatory vs. barrier analysis) and default values (VSdefault, Wdefault) not correctly sourced from the latest IPCC guidelines.
- Eleven corrective actions required, spanning project start date definition, KML file completeness, stakeholder engagement clarity, SDG monitoring details, and alignment of Wsite monitoring with AMS III.D Clarifications.
- No buffer pool percentage is stated in any available document, leaving permanence risk unaddressed despite the project's 7-year crediting period.
- Five contradictions identified across documents, including conflicting characterisation of the baseline (modelled vs. measured), the additionality test type (investment vs. combined), and the presence of a grievance mechanism (true vs. false) between the 2024 and 2025 monitoring reports.
- Leakage deduction of 0% justified only as 'deemed negligible' with no quantified analysis, while the validation report (Dec 2025) characterises the justification as 'quantified' — an unresolved inconsistency.
