This paper describes outline of approach to confidence building including conventional risk assessment techniques in projects for CO2 geological storage. The decision to proceed with the CO2 geological storage in a particular reservoir system must be made that take into account a number of arguments for the effectiveness of the confinement of CO2 within the reservoir. These decisions must provide sufficient confidence and demonstrate that an efficient strategy exists to deal with any uncertainties in our understanding. In order to make the arguments for effectiveness of confinement more rigorous and transparent, we need a comprehensive framework that is much broader than a quantitative risk assessment. Multiple lines of reasoning based on a variety of evidence are necessary in order to develop a robust argument to support long-term effectiveness in the presence of uncertainty and to communicate confidence among various types of stakeholders.
