Mast Wood Preserve MT1

Audit Analysis

Mast Wood Preserve MT1 is a Puro.earth wood-burial project with VVB-confirmed additionality and inherently low reversal risk due to full burial, but it carries four material findings from the verification audit, a project-specific baseline with no stated reassessment date, and a thin 0% leakage justification. The verified ERR for the first monitoring period is roughly six times the linear pro-rata expectation, which is plausible for a front-loaded burial project but warrants scrutiny. Key MRV parameters (fnrb, usage rates, buffer pool) are absent from the extracted record.

Project Description

Red Flags

• ⚠Four material findings in the verification report, including inconsistencies in LCA and CORC documentation that 'materially affected CORC quantification' and a methodology deviation on moisture-content measurement (off-site lab vs. required on-site measurement).
• ⚠No buffer pool percentage stated in any available document, leaving permanence protection unquantified despite the project type.
• ⚠Verified ERR of 4,277.66 tCO₂e for a 7.5-month monitoring period is approximately 6.2× the linear pro-rata expectation (~685 tCO₂e) derived from the 6,164.84 tCO₂e lifetime claim over ~67.5 months; while front-loading is plausible for wood burial, the ratio warrants methodological clarification.
• ⚠FPIC was not conducted and the grievance mechanism was absent from the initial audit submission, only added as a corrective action.
