Avonmouth Production Facility

Audit Analysis

The Avonmouth carbonated materials project has a VVB-verified investment additionality test and documented end-use tracking, but suffers from a project-specific baseline, completely unaddressed leakage, and three material findings including a RECs eligibility issue. The verified ERR for the most recent 3-month monitoring period (1,574 tCO₂e) is roughly 42% of the pro-rata expectation derived from the prior full-year figure (14,873 tCO₂e), raising questions about production consistency. Multiple MRV parameters (FNRB, usage rate, ex-ante lifetime estimate) are absent from the record.

Project Description

Red Flags

• ⚠Leakage is entirely unaddressed: no deduction percentage and no justification appear in any available document, despite the project type (alternative materials production) where displaced material or process changes could generate leakage.
• ⚠Material finding: RECs certificates used in the project are not eligible under Puro's clarification CL023 CMA, and a FAR corrective action was issued requiring future RECs to meet Puro eligibility requirements.
• ⚠The verified ERR dropped from 14,873 tCO₂e (full-year period, Dec 2024 report) to 1,574 tCO₂e (3-month period, Apr 2026 report), which is only ~42% of the pro-rata expectation (~3,718 tCO₂e), suggesting a significant production or methodology change that is not explained in the extracted record.
• ⚠Safeguards documentation is inconsistent: the December 2024 verification report states safeguards are mentioned, while the December 2025 report states they are not; no FPIC or grievance mechanism is confirmed.
