“…The proposed criteria for the both frequency and severity categories were also based on Bowden et al (2013aBowden et al ( , 2013b) and on the industrial risk analysis guide (FEPAM, 2001), risk assessment tool and guidance (HSE 2008) and the standard risk management of Bahia [Bahia (Estado), 2009], and Australian Standards (2004) strongly cited by Fletcher (2005) and Underschultz et al (2011). Despite the references FEPAM (2001), HSE (2008) and Bahia (Estado (2009) are not specific to the risk of CO 2 storage, they are consolidated technical risk references.…”

Carbon geological storage (CGS) projects are designed to securely store carbon dioxide (CO 2 ) for thousands of years. Because of this, there are several studies to evaluate the potential risks of long-term storage of CO 2 in geological formations. This paper presents a new method for the qualitative risk assessment of CGS: the risk assessment of stored CO 2 (RA-CO 2 ) method. It consists of the systematic and structured identification of CO 2 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-CO 2 method. The characteristics of the RA-CO 2 method enable a comprehensive understanding of the underground evolution and future behaviour of the CO 2 in various time scales and their influence on safety. For future studies, the validation of the proposed RA-CO 2 method using a real case study is recommended.Keywords: risk assessment of stored CO 2 ; RA-CO 2 method; qualitative risk assessment; CO 2 leakage; CO 2 geological storage; CGS.Reference to this paper should be made as follows: Paraguassú, M.M., Câmara, G., Rocha, P.S. and Andrade, J.C.S.

“…While the core structure may be very similar, some assessment components are complementary: human health RA is focused on hazard assessment, effects assessment and consequences, while engineered systems' RA is focused is on "establishing the context and vulnerability of potential receptors and the risk management steps, particularly the treatment of risk, monitoring and review" [IEAGHG, (2009), p.23].

Carbon capture and storage (CCS) is included in the list of technological processes that could reduce point source carbon dioxide emissions that contribute to climate change. For geological storage projects, global frameworks for environmental and human health risk assessment (RA) and risk management (RM) have been developed within various regional and national jurisdictions as well as by non-government organisations since the 2005 Intergovernmental Panel on Climate Change Special Report on CCS. This article provides an updated compendium of elaborated RA/RM frameworks in leading jurisdictions for CCS in the regulatory and non-regulatory contexts including online resources. Using a 3-or 4-step RA, there is an emphasis on storage site selection and characterisation; an iterative approach is recommended for RM emphasising monitoring and re-assessment; and other risk-based considerations such as communications and transparency are discussed more frequently in non-government guidance. Comprehensive risk estimation is not yet promoted.

“…More recently Koornneef et al (2012), Bowden et al (2013b) and Pawar et al (2015) expanded the spectrum of environmental risks for the natural environment: CO 2 , brine or process contaminants can affect air, soil and groundwater quality. Bowden et al (2013a), in their list of biosphere risks, extended this further to include wildlife, prairie, recreation and industry assets related to air, soil and water issues. Jones et al (2015) reviewed research and experience regarding the potential impacts of CO 2 leakage on potable water resources and ecosystems.…”

With a focus on risk management (RM) in injection and storage for carbon capture and geological sequestration (CCS), an expert elicitation of scientific judgements quantified collective uncertainty ranges for a number of difficult environmental and human health risk challenges. Results suggest similarities and differences in opinions, an outcome that may be reflective of both the newness and the complexity of this technology. A suitable monitoring period was estimated at about a century; however, uncertainty was three orders of magnitude, with an upper (5th percentile) value of almost 1,000 years. For selected low probability high impact georisks, only site selection and monitoring were considered 'very' effective RM options. Monitoring, well integrity studies, emergency response plan, automatic emergency shut down system and training were considered 'very' or 'extremely' effective in managing two risks more directly related to human health. Experts responded with a wide uncertainty spread for a regulated threshold of minor, major and catastrophic leakage. A companion paper discusses elicitation findings for issues related to risk assessment.
