I am grateful to my hon. Friend for that intervention. I will certainly salute the flag, and I wish to thank him for his work as chairman of the all-party group on polar regions. We have worked very effectively together, and I am grateful to him for coming along to the debate. We will continue to work together because, as I have stressed, this is not just a matter of getting the Bill through Parliament, but a matter of what happens thereafter.
Let me speak about the details of the Bill, which I know hon. Members will have read with great interest. The two parts of the Bill, as I mentioned, build on treaty obligations, the need to maintain and where possible strengthen the British presence, and the good work that our scientists and explorers have done over two centuries. The first part deals with environmental emergencies, and enhances contingency planning for such emergencies. That is important because of the increasing pressure on the Antarctic. Part 1 raises the issue of liability and passes to operators and others the responsibility to make sure that they properly prepare for their activities.
The provisions for environmental emergencies cover the impact not of routine operations, but of accidents and unpredictable incidents that result in environmental damage—for example, ship groundings. There have been one or two shipping accidents. My hon. Friend the Member for Christchurch (Mr Chope) spoke about Argentina. The biggest single accident involved a ship from Argentina, which dispensed 600,000 litres of diesel, resulting in a huge $10 million bill for the clean-up. Appropriate contingency measures are important, and responsibility for accidents should be properly allocated. That is a useful point to make.
Part 1 also requires operators to secure adequate insurance, a point that has been discussed with my hon. Friend the Member for Richmond Park (Zac Goldsmith). It is important to underline the obligation for operators to be properly insured for whatever they intend to do in the Antarctic.
