Avoidance of Methane Emissions at Organic Compost Soil Amendment Facility

Integrity

The project’s integrity is supported by VVB-confirmed additionality through an investment test and a quantified leakage deduction of 0% in the verification report. That said, the verification report also records material findings about green waste being included in calculations even though not all received waste was used, and the reversal risk is not addressed because reversal events are marked as not addressed and no buffer pool is stated.

Transparency

Transparency is moderate because the monitoring period, verifier name, methodology version, and registry are identified in the available documents. However, the record does not provide claimed or verified ER totals, and several operational fields such as usage monitoring and FNRB inputs are not stated, which limits auditability.

Claim Safety

Claim safety is weakened by the verification findings that question the accuracy of waste accounting and the source/location information for purchased green waste. The project does benefit from a quantified leakage treatment and a project method baseline, but the absence of verified usage-rate details and the calculation concerns increase over-crediting risk.

Documentation

Documentation quality is fair because multiple official documents were used and extraction confidence is high. Still, some key items are missing from the extracted record, including buffer pool information, verified totals, and several monitoring inputs, so the evidence set is incomplete for a high-confidence assessment.

Overall

I privileged the verification report over the earlier PDD where the documents conflict, because it is more recent and directly reflects the monitored period; that means I treated leakage as quantified, additionality as investment-test based, and the crediting period as the monitoring-period slice rather than the full PDD period. The contradictions matter: the PDD and verification report differ on additionality framing, leakage treatment, and crediting period, which lowers reliability and keeps the score below a strong-investment grade. Under the deterministic gate rules, the integrity score remains above 4.0 so no overall cap is triggered, but the unresolved accounting findings and missing claim totals still constrain confidence.
