Analysis

A novel accelerated-carbonation sequestration project in Switzerland with VVB-confirmed additionality and well-documented safeguards, but significant gaps in permanence treatment (reversal risk unaddressed, no buffer pool), unclear leakage quantification, and a monitoring deviation that relies on signed declarations rather than direct measurement. Multiple procedural corrective actions remain open, and low extraction confidence in the source documents limits assurance.
