⁵ Internationally, the first steps to mitigate the impact of climate change were taken in 1992 with the United Nations Framework Convention on Climate Change (UNFCCC). The Kyoto Protocol—an addition to the UNFCCC—expressly identified ‘research on, and promotion, development and increased use … of carbon dioxide sequestration technologies’ for promoting sustainable development, (Kyoto Protocol to the United Nations Framework Convention on Climate Change, 10 Dec 1997, UN Doc FCCC/CP/197/L.7/Add. 1, art 2, section 1(a)(iv) <http://unfccc.int/resource/docs/convkp/kpeng.pdf> while at their Hokkaido Summit in 2008, G8 leaders agreed to establish an international initiative with the support of the International Energy Agency ‘to develop CCS technology roadmaps and co-operate through existing and new partnerships’ <http://www.mofa.go.jp/policy/economy/summit/2008/doc/doc080714__en.html>. At European level, the European Climate Change Programme was launched in 2000 to identify and develop an EU strategy to achieve a reduction in greenhouse gas emissions to 8 per cent below 1990 levels by 2008–12, as required by the Kyoto Protocol (The European Union Commission, Towards a European Climate Change Programme <http://eur-lex.europa.eu/LexUriServ/site/en/com/2000/com2000_0088en01.pdf>). The ‘climate and energy package’ (which was agreed by the European Parliament and Council in December 2008 and became law in 2009) includes the Directive on the Geological Storage of Carbon Dioxide Directive 2009/31/EC <http://eurlex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2009:140:0114:0135:EN:PDF>. The Storage of Carbon Dioxide (Licensing) Regulations 2010 partially fulfil the UK's obligation to transpose the Directive into UK domestic law, stipulating, inter alia, that geological storage of CO₂ will be possible only with an appropriate permit.

⁶ ‘The 1990 baseline’ means the aggregate amount of (a) net UK emissions of carbon dioxide for that year, and (b) net UK emissions of each of the other targeted greenhouse gases for the year that is the base year for that gas: section 1(2) of the Climate Change Act 2008.

⁸ Carbon capture and storage is said to be something of a misnomer given that, ‘storage assumes that materials will be retrieved, whilst disposal aims to store and isolate materials for longer periods, perhaps for many tens of thousands of years in the case of carbon dioxide and nuclear waste’: Evans, Stephenson and Shaw (n 1) S303.

⁹ While the directive assumes that CCS may be deployed both under terra firma and under the seabed, for the present the UK is focusing on the latter hoping to exploit its geophysical circumstances in light of decades of gas and oil exploration and extraction.

¹⁰ Directive 2009/31/EC, art 39 (see n 5).

¹¹ The issues raised by the storage of captured CO₂ have much in common with those associated with the underground storage of natural gas, particularly in relation to the nature of, and title to, the storage space. See e.g. Central Kentucky Natural Gas v Smallwood 252 S.W.2d 866 (Ky Ct. App 1952) in which the main question was whether rent payable for a natural gas storage space should be paid to the surface owner or the mineral owner. However, unlike captured CO₂, natural gas is generally stored for only short periods of time and, because it is a valuable commodity, the ownership of the gas itself is significant (where, for example, it has migrated into neighbouring land: see e.g. Hardwicke, RE, ‘The Rule of Capture and Its Implications As Applied to Oil and Gas’ (1935) 13 TexLRev 391Google Scholar).

²¹ In EOR, CO₂ is injected into a depleting oilfield to reduce the viscosity of the oil. As it sweeps through the reservoir, it releases oil additional to that recoverable by ordinary production methods. The first commercial CO₂ EOR project was initiated in 1972 in Texas: Russial, TJ, CCS: Legal and Regulatory Framework – 10 Year Progress Report (United States Carbon Sequestration Council 2010) 4Google Scholar. During the early 1980s, EOR projects using CO₂ were undertaken in the UK at the Egmanton and Bothamsall oilfields in the East Midlands but the results were disappointing and the research was ended because of ‘prohibitive costs’: Evans et al (n 1) S310.

²⁵ Section 1 of the Energy Act 2008. Under the UN Convention of the Law of the Sea (UNCLOS) 1982, territorial waters may extend 12 nautical miles from its baselines. The Crown Estate owns the majority of the seabed around the UK out to the 12-nautical-mile limit. The 2008 Act asserts the right of the Crown under art 56(1) of UNCLOS to a Gas Importation and Storage Zone (GISZ) for the storage of natural gas and CO₂. The area of the GISZ is designated by the Gas Importation and Storage Zone (Designation of Area) Order 2009 (SI 2009/223).

The answer may be found in the Tasmanian case of Davies v Bennison (1927) 4 TLR 8, where Nicholls CJ pointed out that ‘if the hovering aeroplane is perfected, the logical outcome of Lord Ellenborough's dictum would be that a man might hover as long as he pleased at a yard, or foot, or an inch, above his neighbour's soil, and not be a trespasser, yet if he should touch it for one second he would be’.
