Analysis

The Hexi Biogas project is a VCS-registered biogas recovery project in China using AMS methodologies, with VVB-confirmed additionality and no material findings. However, the project-specific modeled baseline, absence of a stated buffer pool, inconsistent leakage treatment across documents, and a significant under-delivery relative to the PDD's lifetime estimate (verified ERR is roughly 29% of the pro-rata expectation) raise moderate concerns about baseline robustness and permanence safeguards.
