Treaty of Lisbon (No. 8)

I agree with my hon. Friend entirely. As she will know, the challenge is even more complex in relation to shipping. It is not simply a question of divvying up the emissions according to which port a ship leaves and which one it arrives in. We need to address the question of fuel bunkering; if that happens in international waters, who is responsible for the emissions? We also need to deal with the question of flags of convenience, because if the trading were arranged on that basis, some countries might suddenly find that they had to take responsibility for a lot of emissions. This is a complex issue, and it needs to be dealt with on an international basis.
