Amendments to MARPOL Annex VI, adopted at IMO MEPC 58 on 10 October 2008, will become effective from 1 July 2010.
This ClassNK Technical Information provides additional information on the modified regulations other than the outline of the amendments to Regulation 13 Nitrogen Oxides (NOx) and Regulation 14 Sulphur Oxides (SOx) and Particulate Matters already described in ClassNK Technical Information No.TEC-0771.
