Emissions of Oxides of Nitrogen from ships specifically referred to as NOx emissions is a burning issue today. This is being regulated by the International Maritime Organisation’s convention Marpol Annex VI, which deals with marine pollution from ships. NOx is very harmful to the environment which leads to formation of ground level ozone and triggers serious respiratory and cardiovascular problems. NOx impacts on human health and environment and is a relevant substance contributing to climate change. The International Maritime Organisation (IMO) has set limits to these emissions from ships. This implementation process commenced in January 2000, with the enforcement of a IMO Tier 1, which restricts the emission limits of NOx from large slow speed diesel engines to17 gms/kWhr. Further reduction in NOx limit was affected in January 2011, with the enforcement of IMO Tier II, bringing down the limit to 14.4 gms/kWhr. The emission limits will be reduced further in January 2016 with a possible enforcement of IMO Tier III, where the NOx reduction would be reduced to 80% of the present value.
When these limits are set by the IMO, a reasonable notice period is available, between the proposed and implementation date, to enable all players in the maritime industry to gear up for the change. Meetings are held between these dates, proposed draft amendments are circulated for consultation. Such amendments may include looking at the postponement of the implementation date. The consultation group includes maritime regulatory, legislative and surveying authorities. Ship builders, Classification Societies, Flag state, Port State control authorities, various environmental agencies and engine manufacturers around the globe will also form a part of this wide consultation group. A major decision follows this consultation, for IMO to come up with a final enforcement date for Tier III.
Presume June 2015 to be the intermediate date for review, of the NOx Tier III limit.
Create a report or a presentation to a variety of interest groups addressing NOx emissions from ships. Your report or presentation should include but not limited to the following :
• Analyse the problem from various angles and identify its impact on the maritime world.
• Identify the pros and cons of postponing the implementation date from January 2016 to a further period of 4 years, and justify your argument.
• Identify and justify the likely stands the various players of maritime world adopt during this major decision making process.
• Summarise the final outcome, to be submitted before June 2015, which in your opinion is in the best interest of the maritime world, clearly justifying the same.
