The key instruments in this context are: (1) 1972 London Dumping Convention [22], as amended by the 1996 London Protocol [23]; (2) 1992 OSPAR Convention [24] for the protection of the marine environment of the North

East Atlantic; and (3) the 2009 EC Directive on Geological Storage of Carbon Dioxide (EU CCS Directive) [25], which applies to the UK as a consequence of its membership of the European Union. The 1972 London Dumping Convention and subsequent Protocol establish a framework for managing the dumping of wastes and other matter at sea. The definition of ‘dumping’ in the 1996 London Protocol includes ‘any storage of wastes or other matter in the seabed or subsoil thereof from vessels,

aircraft, platforms or other man-made structures NU7441 cost at sea’ [26]. ‘Wastes and other matter’ are broadly defined as ‘material and substance of any kind, form or description’ [27]. The Protocol prohibits the dumping at sea of all substances except for those listed in its Annex 1. For the listed substances, a permit must be granted in accordance with detailed technical and environmental conditions set out in Annex 2 and associated guidelines. Following amendments agreed in November 2006, ‘CO2 streams’ are included in Annex 1, and may be disposed of provided that (1) the disposal is into a sub-seabed geological formation; (2) the stream consists overwhelmingly CO2; and (3) no wastes or other matter are added buy IWR-1 for the purpose of their disposal [28]. The 1992 OSPAR Convention establishes a framework for managing the marine environment of the North

East Atlantic region (excluding the Baltic and Mediterranean Seas) [29]. The Convention requires its Parties, Endonuclease inter alia, to ‘take all possible steps to prevent and eliminate pollution’ and ‘take the necessary measures to protected the maritime area against the adverse effects of human activities so as to safeguard human health and to conserve marine ecosystems…’ [30]. It contains detailed obligations concerning: environmental quality assessment (Annex IV of the Convention); protection and conservation of ecosystems and biological diversity (Annex V); and pollution arising from land-based sources (Annex I), dumping and incineration (Annex II), and offshore sources (Annex III). In 2007 States Parties to the Convention adopted, by consensus, several amendments designed to enable regulated offshore CO2 storage activities. Annex II of the Convention was amended to specifically permit the dumping of CO2 streams from CO2 ‘capture processes’ subject to four conditions. The first three of these conditions are identical in substance to those found in the 1996 London Protocol.
