Analysis

The Mariposas Hydroelectric Project is a VCS-registered renewable energy project in Chile with a verified combined additionality test, a jurisdictional baseline reassessed in 2023, and no inherent reversal risk. However, the verification report identified 18 material findings and corrective actions related to calibration gaps, missing ex-ante parameters, and equipment misidentification, which significantly undermine confidence in the MRV chain. The project delivered 21,476 tCO2e for the 2022–2023 monitoring period, below ex-ante estimates due to drier hydrological conditions, which is a conservative outcome.
