Metoder och styrmedel för att minska sjöfartens utsläpp av kväveoxider.

Since nitrogen oxides, NOx are harmful to human health and the environment, the International Maritime Organization, IMO has proposed reductions of the allowed amount of NOx-emissions from vessels in certain areas. The Swedish Shipowners Association together with others are critical to the suggestion. They are afraid that the cost for the installation of the reduction technique will be so expensive that the shipping business would lose competitiveness and that the goods will find other ways. In this paper different alternatives, such as NOx-reduction techniques, economical instruments of control, alternative fuels etc. to reduce NOx- emissions are described and analysed. Some alternatives are relativley new and unrealible, while others not have the potential to meet the future demands. The alternatives which are tested and proven are quite expensive and space demanding, but all alternatives can contribute
