Audit Analysis

The Butterfly Effect is a Gold Standard cookstove project in Mexico's Monarch Butterfly Biosphere Reserve with a combined additionality test and no material findings, but significant documentation gaps including no verification report, unconfirmed VVB oversight, and a project-specific baseline with no stated reassessment date. The project delivered only about 30% of its pro-rata ex-ante expectation for the elapsed monitoring period, indicating conservative crediting but also questioning the robustness of the original baseline assumptions.

Red Flags

  • No verification report found in the extracted record; VVB name and independent verification of additionality are not confirmed in available documents
  • Project-specific baseline with no stated reassessment date, reducing confidence in baseline validity over the 5-year crediting period
  • Leakage is described as 'quantified' in the monitoring report but no deduction value is provided, creating an internal inconsistency
