The shipping industry is a relatively small contributor to the total volume of atmospheric emissions compared to road vehicles and public utilities such as power stations while atmospheric pollution from ships has reduced in the last decade. There have been significant improvements in engine efficiency. Improved hull design and the use of ships with larger cargo carrying capacities have led to a reduction in emissions and an increase in fuel efficiency. Moreover, a new annex to the International Convention for the Prevention of Pollution from Ships (MARPOL 73/78) entered into force in 2005 year, setting formal limits on sulphur oxide (SOx) and nitrogen oxide (NOx) emissions from ship-generated (bunkers or engine) exhausts and prohibiting deliberate emissions of ozone-depleting substances.

Revised MARPOL Annex VI - Regulations for the Prevention of AirPollution from Ships- and NOx Technical Code 2008, 2009 Edition -
Following three years of extensive work, IMO's Marine Environment Protection Committee adopted in October 2008 the revised regulations for the prevention of air pollution from ships, which enter into force on 1 July 2010.
This publication features:
The revised MARPOL Annex VI, the revised regulations on prevention of air pollution from ships engaged in international trade, including emissions limits and operational requirements for prevention of harmful emissions of ships' exhaust and cargo vapours.
The NOx Technical Code 2008, which is made mandatory under MARPOL Annex VI for all marine diesel engines with a power output of 130 kW or more and provides the requirements for testing, survey and certification of marine diesel engines.
The Standard specification for shipboard incinerators, as well as other relevant information on prevention of air pollution from ships.
It also includes a preview of future IMO work by in the field of preventing harmful emissions from ships.
