Changwa 10 MW Small-scale Hydro Project

Audit Analysis

The Changwa 10 MW small-scale hydro project in China uses a jurisdictional baseline and an investment additionality test, both of which are structurally sound for a grid-connected hydro project. However, the available record contains only validation-era documents with no monitoring reports or verified emission reduction data, and the extraction confidence on key documents is low, leaving significant evidence gaps. The claimed lifetime reductions of ~155,600 tCO₂e over seven years are internally consistent with the plant's capacity, but cannot be independently confirmed without verified monitoring data.

Project Description

Red Flags

• ⚠No monitoring reports or verified ERR figures are present in the extracted record; the project's crediting period ended in 2022 yet no post-validation data is available
• ⚠Minimum extraction confidence is rated low, indicating at least one key document was poorly readable and key fields could not be reliably extracted
• ⚠Additionality verification by the VVB is not confirmed in the available data despite an investment test being identified
• ⚠Crediting period dates are inconsistent between the validation report (2015-07-09 to 2022-07-08) and another source (2015-09-07 to 2022-08-07)
