CPA # 2 Improved Cooking Stoves for Nigeria, GS 1352

Audit Analysis

This Gold Standard improved cooking stove PoA in Nigeria has a VVB-verified additionality assessment and a quantified 5% leakage deduction, but suffers from a project-specific baseline, no stated buffer pool, contradictory reversal-event reporting, and self-reported usage monitoring. Multiple ERR figure discrepancies across monitoring and verification reports, combined with CORSIA eligibility and an unknown CCP status, elevate over-crediting and dual-channel risk. The project is functional but carries moderate data-reliability concerns that temper confidence in the claimed reductions.

Project Description

Red Flags

• ⚠Reversal events are described as 'reported' in the 2022 verification report but 'not addressed' in the 2024 verification report, and no buffer pool percentage is stated in any available document, leaving permanence risk unquantified.
• ⚠Usage monitoring relies on self-reporting (2024 verification report) rather than independent verification, and neither the assumed nor verified usage rate is stated in the extracted record, weakening the evidentiary basis for emission reductions.
• ⚠The project is CORSIA-eligible while its CCP status is not stated in any available document, creating an unresolved dual-channel allocation risk.
• ⚠Multiple ERR figures conflict across documents (e.g., 26,905 tCO₂e verified in 2020 vs. 62,459 tCO₂e verified in 2018; 5,781 tCO₂e claimed in 2023 vs. 20,229 tCO₂e claimed in 2022), and the 2024 verification report itself notes that GS passport values do not match CDM monitoring report figures.
