Audit Analysis

The Mansfield Forest Carbon Offsets project (Sandy Cross Forest Preservation) is a 40-year urban tree preservation project under the City Forest Credits standard with a verified combined additionality test and a 10% buffer pool. However, reversal risk over the 40-year crediting period is explicitly not addressed, the baseline is project-specific without a stated reassessment date, and the leakage deduction percentage is not quantified in the available documents. The project shows no contradictions and all verification issues were closed, but several key permanence and baseline parameters remain unconfirmed.

Red Flags

  • Reversal events are explicitly 'not addressed' in the verification report despite a 40-year crediting period for a living forest asset
  • Leakage is described as 'quantified' in the justification field but the actual deduction percentage is not stated in any available document
  • Baseline is project-specific with no stated date of last reassessment, limiting confidence in long-term baseline validity
