Analysing the regulation of vessel-source pollution from the perspective of the political interests of key players in the ship transportation industry, Khee-Jin Tan offers a comprehensive and convincing account of how pollution of the marine environment by ships may be better regulated and reduced. In this timely study, he traces the history of regulation at the International Maritime Organisation (I.M.O.) and investigates the political, economic and social forces influencing the IMO treaties. Also examined are the efforts of maritime states, ship-owners, cargo owners, oil companies and environmental groups to influence IMO laws and treaties. This is an important book which offers solutions for overcoming the deficiencies in the regulatory system and uncovers the politics behind the law for the first time. It will be of great interest to professionals in the shipping industry as well as practitioners and students.
