Full title and description

St ISO TR 27915-2017 — Carbon dioxide capture, transportation and geological storage — Quantification and verification. This Technical Report provides guidance and a review of practices for quantifying and verifying greenhouse gas (GHG) emissions and emission reductions associated with carbon capture and storage (CCS) projects across the full project life cycle (capture, transport and geological storage).

Abstract

ISO/TR 27915:2017 presents a review of publicly available literature and current practice to identify materially relevant issues and options for "good practice" in quantification and verification (Q&V) of GHG emissions and reductions at the project level for CCS. The document addresses Q&V boundaries for integrated CCS components, composition and measurement of the CO2 stream, identification and quantification of direct and indirect GHGs across capture, transport and storage, monitoring objectives and sampling strategies, GHG data collection and reporting, agreed verification criteria, and a lifecycle assessment approach to estimating project-level emissions and emission reductions.

Scope

This Technical Report is intended as a reference for the development of technical standards and guidance for project-level quantification and verification of GHG emissions and emission reductions for CCS projects. It covers all components of an integrated CCS project (capture, transport, storage) and considers the full project life cycle from assessment, construction and operation through completion and post‑closure. The report includes discussion of measurement and verification of CO2 stream composition and purity, monitoring objectives and methodologies, sampling locations/frequencies, data collection and reporting, verification criteria and lifecycle assessment (LCA) approaches. It provides a review of existing practices and options rather than prescriptive requirements; regulatory or national requirements may supplement or take precedence.

Key topics and requirements

• Project-level Q&V boundaries and approaches for integrated CCS projects.
• Principles for measurement quality: relevance, completeness, consistency/comparability, accuracy, transparency and conservativeness.
• Considerations for fungibility and integrity of emission reductions: realness, additionality, quantifiability, permanence and enforceability.
• Measurement and verification of CO2 stream composition and purity, including other entrained GHGs (e.g., CH4) and impurities.
• Identification and quantification of direct and indirect GHG emissions across capture, transport and storage stages.
• Monitoring objectives, methodologies, sampling strategies, locations, timing and frequency for verification and leakage detection.
• GHG data collection, record keeping, reporting formats and quality assurance/quality control practices.
• Verification procedures, criteria and conformance considerations for independent verification bodies.
• Life cycle assessment (LCA) considerations for estimating net project-level emissions and emission reductions.
• Limited discussion of other environmental impacts and interactions with permitting, stakeholder engagement and risk management.

Typical use and users

Used by CCS project developers and operators, verification and auditing bodies, environmental and energy regulators, consultants, LCA practitioners, research institutions and standards developers. It is useful for teams preparing project-level GHG accounting, monitoring plans, verification protocols, or for organizations drafting national guidance and regulatory frameworks for CCS quantification and verification.
