CGR Guatapara Landfill Project

Integrity

The extracted record does not include the baseline method, methodology, or any reassessment timing, so baseline validity cannot be evaluated (source document listed as unknown). Additionality is also not evidenced because neither the type of additionality test nor confirmation by a VVB was found (source document listed as unknown). Leakage treatment is entirely missing (no deduction or justification found), which is a material integrity gap for methane projects where boundary and displacement effects must be addressed (source document listed as unknown).

Transparency

Core MRV transparency items are absent: the monitoring period, monitoring approach, and both claimed and verified emission reductions were not found in the extracted record (source document listed as unknown). The VVB name is not provided, preventing an assessment of independent assurance and audit trail (source document listed as unknown). Low extraction confidence further reduces transparency because it suggests the underlying document was poorly readable or incomplete.

Claim Safety

Because verified emission reductions were not found, there is no way to reconcile claimed versus verified outcomes or check for over-crediting signals (source document listed as unknown). Baseline and leakage information are also missing, which are central to defensible avoidance claims for landfill methane projects (source document listed as unknown). CCP status and CORSIA eligibility were not found, so downstream claim and double-claim risk cannot be screened (source document listed as unknown).

Documentation

Documentation is very weak: only one evidence document is listed and it is labeled as unknown, with low extraction confidence (source document listed as unknown). Key metadata such as document date, project name, methodology/version, and crediting period were not found, limiting traceability and recency checks (source document listed as unknown). While no material findings or corrective actions are recorded, the absence of verification details makes this non-informative.

Overall

No contradictions were reported in the extracted record, but this appears driven by missing data rather than consistent cross-document evidence (only one low-confidence document is listed). Given the absence of baseline, additionality, leakage, MRV period, and verified reductions, the project cannot be substantiated from the available extracted materials, so scores are conservatively low. Note: if documentation remains below 3.0, transparency would be capped by the stated gate rule in post-processing.
