Carbon Sequestration Risks and Risk Management

This section summarizes the risk assessment approaches and risk management methods that can be applied to study geologic carbon sequestration in California, including CO2 capture, transportation and storage operations. Risk assessment and risk management concepts are introduced and applied. Known hazards from carbon sequestration are discussed individually, and risk reduction options are presented. Human exposure limits, pathways for human and environmental exposure during operations and post‐operations, and how risks change over the time scales associated with storage as the CO2 migrates and reacts in the subsurface environment, are also discussed.
