Audit Analysis
The Içara Landfill Gas Project benefits from the inherent permanence of methane destruction and a VVB-confirmed investment additionality test, but is significantly undermined by 16 material findings in the validation report, including a near-doubling error in the stated annual ERR, missing financial parameters for the additionality case, and methodological non-conformance with ACM0001. Five contradictions between the PDD and validation report (grid emission factor, additionality test type, leakage treatment, benefit sharing, and crediting period) further erode confidence in the project's data integrity. The project is at the validation stage with no monitoring or verification data yet available.
Red Flags
- The validation report identifies 16 material findings, including a methodological non-conformance in the baseline heat-generation calculation (BEHG,y) with ACM0001 v19.0, and missing CAPEX, OPEX, and revenue parameters that underpin the investment additionality test.
- The PDD states an average annual ERR of 290,881 tCO2e, but the validation report's ER sheet calculates 136,084 tCO2e — a 2.1× overstatement in the project document.
- The grid emission factor differs by 50% between documents: 0.2169 tCO2/MWh in the validation report versus 0.3263 tCO2/MWh in the PDD.
- The opening meeting date (23 Jan 2023) preceded the public comment period start (28 Sep 2023), violating VCS Standard procedural requirements.
- The entity commissioning the VVB is inconsistent between the PDD (UniCarbo) and the validation report (RAC Saneamento Ltda.).

Risk Indicators
VVB-confirmed investment test, but CAPEX/OPEX data missing and PDD references a different test type
Inherent permanence — methane destroyed upon collection, no reversal risk
0% deduction deemed negligible (reasonable for LFG), but appendix references a 'quantified' treatment
Project-specific modeled baseline; grid EF contradicted between documents; not yet due for 10-year reassessment
Grievance mechanism present and safeguards mentioned, but FPIC not conducted and benefit sharing not described per VR
CORSIA eligibility and CCP status not stated in available documents
