The emission regulations of NOx and SOx from ships started with this protocol. After that, the severe sulfur regulation was discussed and adopted at MEPC58 held in October 2008. This paper presents the production process and the expected quality of low sulfur marine fuels that will be used in specified sea areas after 2015 and in general sea areas after 2020.
