CTRVV Landfill emission reduction project

Audit Analysis

The CTRVV landfill gas project in Brazil has a solid additionality foundation (combined test confirmed by a reputable VVB) and no material findings, but is undermined by a critical discrepancy in which the 2021 monitoring report shows zero verified emission reductions for a nine-month period, a contradiction between the PDD and later monitoring reports on whether the baseline was measured or modeled, and an inconsistent treatment of leakage across documents. The project-specific baseline and the absence of a stated buffer pool or permanence mechanism further limit confidence in the integrity of the credit claims.

Project Description

Red Flags

• ⚠The 2021 monitoring report (covering Apr–Dec 2020) records zero verified emission reductions despite a claimed figure of 97,642 tCO₂e, suggesting either a complete monitoring failure or a data extraction anomaly that cannot be resolved from available documents.
• ⚠The PDD (2017) describes the baseline as modeled and leakage as quantified, while the 2021 monitoring report describes the baseline as measured and leakage as not addressed — a direct contradiction that undermines confidence in the MRV chain.
• ⚠No buffer pool percentage, reversal-event history, or permanence mechanism is stated in any available document, leaving the permanence of issued credits unverified.
