MSW to Compost through BSF Rearing process

Audit Analysis

A VCS-registered BSF-rearing compost project in India with VVB-confirmed additionality and a standardized methodology (AMS-III.F v12.0), but significant gaps in permanence safeguards (reversal events not addressed, no buffer pool), a contradictory 0% leakage justification, and two open forward actions. The project delivered exactly the claimed 7,335 tCO₂e for its first monitoring period, though the PDD had initially estimated 12,134 tCO₂e before validation reduced the figure by roughly 40%.

Project Description

Red Flags

• ⚠Reversal events are explicitly 'not addressed' in the verification report, and no buffer pool percentage is stated — a material permanence gap for a compost project where the product can decompose
• ⚠Leakage justification is contradictory: the monitoring report (Dec 2022) describes it as 'quantified' while the validation report (Dec 2024) describes it as 'deemed negligible', yet the deduction is 0% in both cases
• ⚠Two Forward Action requests remain open: maintenance of aerobic conditions to comply with the methodology, and issuance of an RFP document post-2027 for the crediting period
• ⚠The PDD (Apr 2023) estimated 12,134 tCO₂e while the validation report (Dec 2024) confirmed only 7,335 tCO₂e — a 40% reduction that signals initial over-estimation in the project design
