Abstract

The issue of climate change affecting the ozone layer demands critical efforts from different sub sectors of the world carbon source emission sources cutting across the Agricultural sub sector, the oil and gas sub sector, the fossil fuel technology sub sector to mention but a few. Under the fossil fuel technology sub sector, the marine industry by having fossil fuel powered ships in the waters contributes a good measure to greenhouse gas emissions. In view of this fact the sector has instituted good number of measures to address the mitigation of ship source emissions through regulations developed by the International Maritime Organization (IMO).The work first reviewed the various air emissions control mechanisms developed for the sector. Next, the work developed a model of compliance to these rules for both flag states and port states using port state control mechanisms. Both oxides of nitrogen NOx and oxides of sulphur SOx compliance were covered in the light of IMO, Marine pollution convention MARPOL73/78 as currently amended. The theories of efficiency and responsiveness were applied in eliminating laxity in the overall ocean emissions sub sector.
