As we all know, the MARPOL agreement is a really good multilateral tool that is available to countries around the world in arresting the effects of climate change, particularly in the marine environment, and that is a really important thing. Certainly, you know, we've all been signed up in New Zealand here to MARPOL since 1998, and we've acceded to four of the six annexes already, and it's good that Annex VI, which is really fixated on limiting air pollution of ships around ports and harbours, is a good thing for us to be signing up for.
