Full title and description

ISO 27914:2017 — Carbon dioxide capture, transportation and geological storage — Geological storage. This International Standard provides requirements and recommendations for the geological storage of CO₂ streams to promote safe, long‑term containment that minimizes risk to the environment, natural resources and human health.

Abstract

ISO 27914:2017 establishes requirements and recommendations covering site screening and selection, site characterization, design and development, operation of storage sites, and preparation for site closure for geological storage of CO₂. It applies to onshore and offshore porous and permeable geological strata (including certain hydrocarbon reservoirs when CO₂ is not injected for hydrocarbon production or CO₂‑EOR). The standard also addresses management systems, stakeholder engagement, risk assessment and risk communication while acknowledging that permitting and legal/property matters are outside its scope.

Scope

ISO 27914:2017 provides requirements and recommendations for the geological storage of CO₂ streams for safe, long‑term containment. It covers both onshore and offshore storage in permeable/porous strata, including some hydrocarbon reservoirs when CO₂ injection is not for hydrocarbon production or CO₂‑EOR. The standard addresses activities from site screening and selection through characterization, design, development, operation, cessation of injection and the post‑injection/closure period. It recognizes site‑specific risk and uncertainty, and excludes regulatory permitting processes and property/right issues.

Key topics and requirements

• Site screening and selection criteria for geological storage projects.
• Subsurface and surface site characterization requirements (geology, hydrogeology, containment and integrity assessment).
• Design and engineering principles for storage facilities and injection operations.
• Operational requirements including monitoring, measurement and verification (MMV) of CO₂ behavior and containment.
• Requirements for preparation for site closure and post‑injection care and monitoring.
• Management systems, risk assessment, risk management and risk communication.
• Stakeholder and community engagement recommendations.
• Clarification that permitting, legal/property rights and regulatory compliance are outside the standard's direct scope.

Typical use and users

Used by project developers and operators of CO₂ storage projects, subsurface and reservoir engineers, geoscientists, environmental and safety managers, regulatory advisors, consultants, and organisations developing corporate management systems for carbon storage projects. The standard is also referenced by regulators and permitting authorities as technical guidance (where appropriate) and by stakeholders assessing project safety and environmental risk.

Related standards

Relevant complementary standards include other ISO documents in the CO₂ capture, transport and storage series such as ISO 27913 (pipeline transportation systems for CO₂ streams) and ISO 27916 (CO₂ storage using enhanced oil recovery), plus greenhouse‑gas accounting standards (for reporting and verification) referenced when quantification and verification are required. National and industry pipeline, well integrity, EHS and environmental standards are also commonly used alongside ISO 27914.

Keywords

FAQ

Q: What is this standard?

A: ISO 27914:2017 is an International Standard that provides requirements and recommendations for the geological storage of carbon dioxide streams to achieve safe, long‑term containment and minimize environmental and health risks.

Q: What does it cover?

A: It covers the lifecycle of a geological CO₂ storage project from site screening and selection, characterization, design and development, operation, through cessation of injection and post‑injection/closure activities, including monitoring, management systems, stakeholder engagement and risk management. It does not include permitting or property/right governance.

Q: Who typically uses it?

A: Typical users are CO₂ storage project developers and operators, reservoir/state/regulatory authorities, engineering and environmental consultants, geoscientists, and organisations implementing management systems for CCS projects.

Q: Is it current or superseded?

A: ISO 27914:2017 is the published first edition (2017). As of early 2026 the standard has been subject to a technical revision and a second edition was under publication (ISO listing indicates an edition 2 in development/under publication). Users should check the current ISO catalogue or their national standards body for the latest edition status before relying on specific clauses.

Q: Is it part of a series?

A: Yes — ISO 27914 is part of the ISO family of standards on carbon dioxide capture, transportation and geological storage (ISO/TC 265), which includes related documents addressing pipeline transport (ISO 27913), CO₂ storage with EOR (ISO 27916) and other topics in the CCS lifecycle.

Q: What are the key keywords?

A: CO₂ geological storage; CCS; storage site screening; site characterization; monitoring and verification; risk assessment; closure planning; ISO 27914.
