I congratulate the hon. Member for Stroud (Neil Carmichael) on introducing the Bill. It is a great pleasure to deal with a genuinely bipartisan Bill. As he rightly said, the Bill follows a consultation on a draft Bill in 2009. I do not propose to detain the House too long on this issue, albeit for possibly a little longer than my 57-second contribution last week.
The Bill would implement a new annex to the Antarctic treaty that was agreed back in 2005 on liability arising from environmental emergencies. It requires anyone undertaking activities in Antarctica to ensure that measures are in place to deal with any environmental damage, together with contingency plans for any damage that might occur. The present Bill was based on the Bill consulted on in 2009 by the previous Government, but it does not contain part 2 of the original Bill covering the requirement for contingency and safety planning by all British operators. In that context, I understand that the Minister’s officials believe that these issues can be addressed through the permit system, so that part of the original Bill is not required. I hope that the Minister will take this opportunity to be a bit more explicit and to send a clear message to operators—and reassurance to those who have a passionate interest in the Antarctic environment—that that is the case, and that the Bill follows the long line of measures to protect this vital environment. I hope that the Minister will deal with that issue when he winds up.
The Antarctic environmental legislation is a very good example of international co-operation on matters of great concern for the future of the planet. The treaty froze territorial disputes relating to the continent in order to pursue peaceful scientific investigation and conservation. Several hon. Members have referred to examples of that, some of them at considerable length. In the 1991 protocol, stringent measures on environmental protection were introduced, including—importantly—a 50-year moratorium on mineral extraction. The current permit requirements for British expeditions entering the Antarctic were introduced in the Antarctic Act 1994—in another example of the bipartisan nature of these discussions and concerns about the issue—which implemented the treaty’s protocol on environmental protection.
Why is this Bill so important and necessary? The Antarctic, as has been stressed by several hon. Members, is a pristine and highly sensitive environment that is of great significance in the global eco-system. It contains, for example, 90% of the ice on earth and 60% to 70% of its fresh water. At a time of rising sea levels—mentioned with great concern yesterday by Mayor Bloomberg in New York—the melting of this ice would see a dramatic increase in sea levels. The seasonal growth of sea ice each year is one of earth’s most significant seasonal cycles, covering 19 million sq km at its maximum extent, which is one and half times the area of the Antarctic continent.
The Southern ocean also dominates the global oceans and influences the climates of many countries. In that context, I was pleased and honoured earlier this year to visit the Australian Antarctic division in Hobart, Tasmania. That is a valuable resource, and the hon. Member for Romford (Andrew Rosindell) will be well aware of the extensive co-operation with our Commonwealth ally, Australia, on this issue. This is a valuable resource not only for Australia but for the international community. It monitors the impact of climate and environmental change, conservation and eco-systems onshore and near shore, and in the vast Southern ocean.
