Implementation of directive 2009/31/EC on the geological storage of carbon dioxide
Guidance document 2, characterisation of the storage complex, CO2 stream composition, monitoring and corrective measures
Publication metadata
The purpose of this set of Guidance Documents is to assist stakeholders to implement Directive 2009/31/EC on the geological storage of CO2 (so called CCS Directive) in order to promote a coherent implementation of the CCS Directive throughout the European Union (EU). The guidance does not represent an official position of the Commission and is not legally binding. Final judgments concerning the interpretation of the CCS Directive can only be made by the European Court of Justice. This Guidance Document 2 (GD2) builds on the first Guidance Document (GD1) that has laid out the overarching framework and nomenclature for the entire life cycle of geological storage activities including its phases, main activities and major regulatory milestones. This non-legally binding document provides guidance on: Site selection; Composition of the CO2 stream; Monitoring; Corrective measures.
