Granja Tres Arroyos Methane Avoidance in Slaughterhouse Effluents Project

Audit Analysis

A CDM methane-avoidance project in Argentina's slaughterhouse sector with a combined additionality test and a project-specific modeled baseline. The project carries a significant data-reliability concern: the lifetime emission-reduction estimate differs by a factor of five between the 2015 validation report and the 2022 monitoring report, and the leakage justification is internally contradictory. All three material findings raised during verification were closed, but the absence of a documented buffer pool, permanence mechanism, or safeguards detail limits confidence in the credit's robustness.

Project Description

Red Flags

• ⚠Lifetime ERR estimate differs by 5.3× between the validation report (33,764 tCO₂e) and the 2022 monitoring report (177,466 tCO₂e), creating serious uncertainty about the true credit volume
• ⚠Leakage justification is contradictory within the extracted record: one source states it was 'quantified' while another states it was 'not addressed', yet the deduction is 0%
• ⚠No buffer pool, permanence mechanism, or reversal-risk mitigation is documented in any available source
• ⚠Three material findings (policy-impact omission, incomplete end-use monitoring, unjustified exclusion of emission sources) were raised during verification, indicating baseline and monitoring weaknesses
