Greater New Bedford Landfill Gas Utilization Project

Integrity

The monitoring record indicates additionality was confirmed by the VVB and the project applies ACM0001, which is generally appropriate for landfill gas utilization. However, the monitoring report (2026-01-12) lists extensive corrective action requests, including errors in emissions calculations (e.g., emergency generator emissions double counting and other spreadsheet/parameter issues) and concerns about calibration/QA-QC for gas measurement equipment, which directly affects baseline and project emissions quantification. Leakage is shown as a 0% deduction while the latest monitoring record does not address leakage justification, weakening confidence that all relevant sources are conservatively treated. Baseline is project-specific and the last reassessment is shown as 2016, which is dated for a 2024 monitoring period.

Transparency

The monitoring report provides a clear monitoring period (2024-01-01—2024-12-31) and identifies the VVB (TÜV SÜD America Inc.), supporting basic traceability. Nonetheless, the extracted record contains major inconsistencies in emission reduction totals across validation/verification documents, which makes it difficult for an external reviewer to reconcile what was claimed versus what was ultimately verified. The monitoring report (2026-01-12) also indicates multiple revisions were needed to align with updated VCS standards and to correct reporting inconsistencies, suggesting the public-facing MRV narrative may have been unstable across iterations.

Claim Safety

The project is marked as not CORSIA-eligible, which lowers the risk of certain high-stakes compliance claims. However, claim safety is materially weakened by contradictions in the emission reduction numbers (including a very large gap between a claimed figure and a verified figure across different validation/verification records) and by the volume of CARs affecting core quantification elements (e.g., methane oxidation efficiency updates, generator emissions treatment, and instrument calibration issues) in the monitoring report (2026-01-12). Leakage treatment is also a concern because the latest monitoring record does not address leakage justification while applying a 0% deduction, increasing perceived over-crediting risk.

Documentation

The evidence set is relatively strong in breadth (PDD, monitoring report, validation report, issuance) with high extraction confidence and a large number of documents used (129). The monitoring report is recent (2026-01-12) and includes detailed CAR narratives, which improves audit trail visibility. Still, the presence of many corrective actions and multiple cross-document contradictions (ERR totals, safeguards statements, crediting period dates) reduces confidence that the documentation is internally consistent and stable over time.

Overall

Key contradictions materially affect reliability. For emission reductions, I privilege the higher verified total of 110,197 from the later validation/verification record dated 2025-12-15 over the earlier 32,417 figure (2025-03-10) because it is later and explicitly presented as verified, but the magnitude of the discrepancy still lowers scores. For leakage justification, I privilege the most recent monitoring report (2026-01-12) stating leakage was not addressed over the older 2022-07-18 monitoring report indicating quantified leakage, because recency is higher-priority for current MRV practice; this worsens integrity/claim safety. For safeguards/FPIC/grievance/benefit sharing, I privilege the more recent monitoring report (2026-01-12) indicating these are present over the 2017-05-26 monitoring report indicating they were absent, but the inconsistency signals reporting drift and reduces transparency. For crediting period, I privilege the later monitoring report (2026-01-12) showing 2016-03-29—2026-03-28 over the 2016-09-08 monitoring report showing 2006-03-28—2016-03-28, because it aligns with a second crediting period extension, yet the conflict indicates boundary/registry clarity issues and lowers overall confidence.
