ESTRE’s Paulínia Landfill Gas Project (EPLGP)

Integrity

Additionality appears reasonably supported because the validation/verification record indicates an investment test and that additionality was confirmed by the VVB. The baseline is project-specific under AM0003 and the last reassessment is dated 2011, which is somewhat dated relative to the 2012–2013 monitoring period. Integrity is materially weakened by inconsistent ER figures across monitoring reports and by the recorded leakage deduction of 120%, which is not credible as a standard leakage deduction and suggests a serious reporting/extraction problem.

Transparency

The extracted record provides a clear monitoring period (2012-10-01 to 2013-09-13), identifies the methodology (AM0003 v3), and names the VVB (Econergy Brasil Ltda.) in the monitoring documentation. Transparency is reduced because key MRV elements (such as the usage monitoring method) are not found in the extracted record. Most importantly, the monitoring reports conflict on both claimed and verified ER totals, making it difficult for an external reviewer to reconcile what was actually monitored and credited.

Claim Safety

The project is explicitly marked as not CORSIA-eligible, which lowers the risk of CORSIA-related misclaims, but CCP status is not found in the extracted record, leaving some market-claim ambiguity. Claim safety is pressured by the large spread between claimed and verified ERs in the 2014-02-24 monitoring report (1,021,281 claimed vs 621,742 verified) and by contradictions with an earlier monitoring report (2012-10-05). The leakage treatment is also inconsistent across monitoring reports and includes an implausible 120% leakage deduction value, increasing the risk that buyers could rely on incorrect or non-comparable figures.

Documentation

Documentation coverage is moderate-to-good given the evidence set includes a PDD, validation report, monitoring report(s), and issuance records, and 33 documents were used in extraction. However, minimum extraction confidence is only medium, indicating some limitations in readability or extraction reliability. Social safeguard documentation is weak in the extracted record (no FPIC and no grievance mechanism evidenced), and safeguards mentions are inconsistent across documents.

Overall

I privileged the more recent monitoring report dated 2014-02-24 for the main ER figures and crediting period because it is later and likely reflects the finalized monitoring/verification outcome for the stated 2012–2013 monitoring window; however, the earlier monitoring report dated 2012-10-05 provides conflicting claimed (378,762) and verified (178,012) ER values, which materially undermines confidence in the MRV record. For safeguards, I treated the inconsistency (validation report 2005-12-16 mentions safeguards, while the 2014-02-24 monitoring report does not) as a reliability gap and scored conservatively, especially given FPIC and grievance are not evidenced in the extracted record. For leakage justification, I privileged the later statement that leakage was quantified (2012-10-05) over the earlier 'not addressed' (2010-03-09), but the presence of a 120% leakage deduction still indicates a serious data quality issue. The crediting period contradiction (2006-09-14 to 2013-09-13 vs 2006-05-01 to 2013-04-30) further signals record inconsistency, so overall scores are reduced for reliability even though additionality is VVB-confirmed and the project is not CORSIA-eligible.
