La Yesca Landfill Gas Project

Audit Analysis

The La Yesca Landfill Gas Project is a registered VCS LFG-to-energy project in Chile with VVB-confirmed additionality, but it carries significant documentation and baseline-validity concerns. The validation report identified 16 material findings (all subsequently closed), including calculation errors in emission-reduction parameters, and the project lacks a buffer pool, any monitoring data, and a confirmed FPIC process. Five contradictions between the PDD and the validation report—on FPIC, benefit sharing, leakage, legal capture requirement, and the lifetime ERR—further erode confidence in the project's data integrity.

Project Description

Red Flags

• ⚠16 material findings in the validation report, including calculation errors in BECH4, DOCj, and TDL values and contradictory statements about the baseline flare, all of which undermine baseline validity even though they were closed
• ⚠No buffer pool is in place and no reversal-risk mechanism is documented; the project simply states reversals are 'not applicable' without a quantitative safety net
• ⚠FPIC status is directly contradicted: the PDD (2025-10-30) states FPIC was conducted, while the validation report (2025-10-31) records it as not conducted; the more authoritative validation report is privileged
• ⚠No monitoring or verification report is available for a project whose crediting period began in March 2023, leaving roughly 2.7 years of operations unverified
• ⚠Leakage deduction is 0% with only a 'deemed negligible' justification, and the PDD (2023) did not address leakage at all
