The key message, really, around this bill is that it is relatively minor and yet it is a positive step for the shipping sector towards a cleaner and healthier sector for people and our environment. What is really rather interesting for me in debating this bill, having been through a whole range of other things, particularly in the energy space and the agricultural space, is that we are kind of late to the piece in this one. With so many other things that the current Government is trying to lead the world on—New Zealand first signed up to MARPOL in 1998, which was some time ago. So 94 other countries are party to Annex VI, representing 97 percent of the world's shipping tonnage. So we are rather late to this, albeit that this particular piece of legislation, which we are happy to support, is in the process of making a difference to the environment and to climate change around the world. It is really important because it takes into account the human environment around courts, it takes into account climate change and ozone layer - depletion both through air-quality regulations and energy-efficiency measures.
