Analysis

This Gold Standard biogas programme in Sichuan has confirmed additionality and a measured baseline, but is undermined by a very large volume of calculation errors (including a double application of an uncertainty factor), unresolved contradictions in verified emission-reduction figures across reporting periods, and a delay in re-validation that extended beyond the first crediting period. The project's data-quality record is weak relative to the scale of credits issued.
