Because of this, there are several studies to evaluate the potential risks of long-term storage of CO2 in geological formations. This paper presents a new method for the qualitative risk assessment of CGS: the risk assessment of stored CO2 (RA-CO2) method. It consists of the systematic and structured identification of CO2 release risk scenarios arising from: seal, well, and fault and fracture zones. The uncertainties associated to each mapped risk scenario and the risks are qualitatively evaluated using the RA-CO2 method. The characteristics of the RA-CO2 method enable a comprehensive understanding of the underground evolution and future behaviour of the CO2 in various time scales and their influence on safety. For future studies, the validation of the proposed RA-CO2 method using a real case study is recommended. International Journal of Environmental Technology and Management
