Adilabad biogas project

Audit Analysis

The Adilabad biogas project has a VVB-verified additionality assessment and a measured project-specific baseline, but the record is undermined by eleven cross-document contradictions, a missing verified ERR figure, and a striking discrepancy between the PDD lifetime estimate (63,961 tCO₂e over five years) and the single-year monitoring claim (72,685 tCO₂e), which represents roughly 568 % of the pro-rata expectation. The 95 % leakage deduction is extremely conservative yet contradicted by a 0 % figure in an earlier verification report, and no buffer pool is documented. Overall the project shows moderate integrity but significant data-reliability and over-crediting concerns.

Project Description

Red Flags

• ⚠The 2025 monitoring report claims 72,685 tCO₂e for the 2024 period while the PDD (2024) states a lifetime estimate of 63,961 tCO₂e for the full 2024–2028 crediting period; the one-year claim is approximately 568 % of the pro-rata expectation (12,792 tCO₂e), indicating a potential over-crediting issue.
• ⚠Leakage deduction jumps from 0 % in the February 2025 verification report to 95 % in the December 2025 verification report with no documented methodological change, raising questions about data reliability.
• ⚠The December 2025 verification report marks reversal events as 'not addressed' while the November 2025 monitoring report states 'none reported'; the higher-priority verification document does not confirm the absence of reversals.
• ⚠Eleven contradictions across the document set (leakage, ERR, usage rate, additionality test type, FPIC, FNRB method, reversal events, crediting period, monitoring method) significantly erode confidence in the data record.
