As Mr McKelvie just recently, in a contribution on the prior bill, noted, shipping is, of course, of fundamental importance to New Zealand's trade. None the less, it's also true that shipping is a major contributor of noxious emissions to the atmosphere, particularly sulphur oxides, nitrogen oxides, and particulate matter, which affect both human health and the environment. Passing this bill will enable us to reduce these emissions and implement greenhouse gas emission reduction measures by aligning our domestic legislation under the Maritime Transport Act 1994 with the International Convention for the Prevention of Pollution from Ships—or MARPOL—Annex VI.
