3.1.2 OSPAR Convention

The OSPAR Convention (The Convention for the Protection of the marine Environment of the North-East Atlantic) has published guidelines concerning risks related to storage of CO2 in off-shore geological formations in the north east Atlantic (OSPAR Guidelines for Risk Assessment and Management of Storage of CO2 Streams in Geological Formation reference number, 2007). Countries that are parties of OSPAR include Belgium, Denmark, Finland, France, Germany, Iceland, Ireland, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom, together with the European Community. The guidelines have been ratified by Norway, Germany, the United Kingdom, Spain, European Union, Luxembourg, Denmark and the Netherlands (July 2011).

The OSPAR guidelines only consider storage related CCS issues. The guidelines have been designed to ensure that if leakage does occur from a site of geological storage of CO2, "it does not lead to significant adverse consequences for the marine environment, human health or other legitimate uses of maritime the area". OSPAR recognises that leakage of CO2 into the marine environment may occur during injection and/or from the storage site after injection. In general the guidelines aim to aid and facilitate the management of a CO2 geological storage site so that:

  • The suitability of a potential site is properly assessed and necessary measures of hazard reduction, remediation and mitigation are identified.
  • Risk characterisation to the marine environment is undertaken for each potential storage site.
  • Monitoring is performed and a strategy to manage uncertainties and minimise risks is developed.

The guidelines also include a framework for risk assessment and management of a geological CO2 storage site, also referred to as FRAM which is an integral part of the OSPAR guidelines. FRAM also considers developments of the London Protocol.

FRAM presents all the possible impacts of an eventual leakage in the marine environment. Section 1 of FRAM introduces a conceptual model of potential environmental pathways and effects (Fig. 3-1) to be considered for the risk assessment and management of offshore storage sites. Appendix 1 of FRAM includes all the relevant information needed for risk assessment and management, while Appendix 2 identifies the issues that need more research. OSPAR-FRAM (2007) Appendix 3 classifies leakage as "the escape of that CO2 stream from the storage formation into overlying formations, the water column and the atmosphere".
