SA TR ISO 27918:2024
[Current]Lifecycle risk management for integrated CCS projects
AS TR ISO 27918:2024 identically adopts ISO/TR 27918:2018, which addresses more broadly applicable lifecycle risk management issues for integrated CCS projects. The focus of this document is on risks that affect the overarching CCS project or risks that cut across capture, transportation, and storage affecting multiple stages. It needs to be noted that environmental risks, and risks to health and safety should be very low for CCS projects provided the project is carefully designed and executed. Risk identification and management is part of the due diligence process.
