The Centre for International Law (CIL) at the National University of Singapore hosted a two-day workshop on greenhouse gas (GHG) emissions and shipping on 13–14 November 2018. The workshop was co-organised with the Maritime and Port Authority of Singapore (MPA). The objective of the workshop was to bring together legal and industry experts to discuss the Initial Strategy on reduction of GHG emissions from ships adopted by the Marine Environment Protection Committee (MEPC) of the International Maritime Organization (IMO) in April 2018. The workshop aimed to explore GHG reduction from legal, technical and industry points of view, while outlining the technical background and major issues in the reduction of GHG emissions. Academic speakers were invited, as well as speakers involved in the development of the strategy at the IMO, the MPA, and from the bunkering and ship and engine manufacturing industries. Ship owners, classification societies and environmental groups were also represented.
