Zaoyuan Solar Cooker Project

Audit Analysis

The Zaoyuan Solar Cooker Project is a Gold Standard cookstove project with a VVB-confirmed investment additionality test and documented safeguards, but it is undermined by a 100% assumed usage rate versus 90.68% verified, a verified ERR figure that represents only a small fraction of the lifetime ex-ante estimate, and 30 corrective actions flagged across the verification and monitoring reports. The project-specific baseline and the absence of a stated FNRB value further weaken the robustness of the emissions-avoidance claim.

Project Description

Red Flags

• ⚠Usage rate assumed at 100% in the validation report but verified at only 90.68% in the 2023 verification report, implying roughly a 10% over-claiming of emissions reductions.
• ⚠Verified ERR of 97,875 tCO2 (2023 verification report) represents only about 19% of the 516,420 tCO2 lifetime ex-ante estimate, raising questions about the realism of the original projection.
• ⚠30 corrective actions were required across the PDD, validation, and monitoring reports, indicating substantial gaps in MRV methodology, parameter documentation, and stakeholder-consultation records.
• ⚠Contradiction between the 2020 PDD (common-practice additionality) and the 2023 validation report (investment test) suggests the additionality basis was revised late in the project lifecycle.
