One of our Government's priorities is to tackle climate change. Shipping is a major contributor of emissions to the atmosphere, particularly sulphur oxides, nitrogen oxides, and particulate matter, which affect both human health and the environment. This bill will enable us to align domestic legislation under the Maritime Transport Act 1994 with the International Convention for the Prevention of Pollution from Ships (MARPOL), Annex VI, which the Cabinet agreed to accede to in 2019.
