VPA 16 - GHG Emission Reduction through use of Bondhu Chula (Improved Cook Stoves) in Bangladesh

Audit Analysis

The Bondhu Chula cookstove project in Bangladesh has a sound methodological foundation with VVB-confirmed additionality and a quantified leakage deduction, but is significantly undermined by an extensive list of over 30 material findings and 25 corrective actions that raise serious concerns about data quality and monitoring rigor. The project-specific baseline, absence of a documented buffer pool or permanence mechanism, and contradictions between documents (particularly on the crediting period) further weaken confidence in the integrity and reliability of the claimed reductions.

Project Description

Red Flags

• ⚠Over 30 material findings and 25 corrective actions identified in the 2023 verification report, including inconsistencies in emission reduction values, missing sample calculations, and widespread data-entry errors in the installation database (47,508 end-users with missing phone numbers)
• ⚠Crediting period contradiction: the 2023 verification report states 2014–2024 while the 2022 validation report states 2021–2026, creating ambiguity about the actual project duration and baseline validity window
• ⚠No buffer pool percentage or permanence mechanism is documented, and no reversal events data is available, leaving the cookstove project's inherent reversal risk (stove breakdown, user abandonment) unaddressed
• ⚠No ex-ante lifetime ERR estimate is available in the extracted record, preventing a reliable pro-rata comparison of verified reductions against the original project estimate
• ⚠Usage rate assumed value is not stated in any available document, making it impossible to assess whether the verified 0.93 usage rate represents an improvement or deterioration relative to the original assumption
