The global shipping industry is of great importance for the economic activity of many countries, as 80%
of commodity trade by volume is carried out by sea transport. Shipping is the most efficient method of international shipping for most goods. It provides reliable, low-cost means of transportation worldwide,
facilitating trade and contributing to the creation of prosperity between nations and peoples. The Greek
shipping industry holds a prominent position in maritime transport worldwide, ranking seventh in the
world and second in the European Union. In addition, the Greek flag remains on the White List of the
Paris Memorandum of Understanding as one of the finest flags, occupying the 24th position among forty
(40) quality flag states. (Paris MoU).
The number of studies addressing the need for drastic measures to reduce emissions of pollutants on
a global scale is significant. Emissions estimation has improved significantly since the mandatory
placement of AIS (AUTOMATIC IDENTIFICATION SYSTEMS) on ships since 2002, providing data
on ship activity, routes and other data required to reduce emissions of pollutants from ships.
Estimation of pollutant emissions using the AUTOMATIC IDENTIFICATION SYSTEMS-AIS has
generally proceeded to two strands: regional studies using sample-based estimates in a marine area with a
mesh that was mainly limited to 5 km and its escalation using port data. The second approach used both
satellite and terrestrial AIS, taking data from AIS such as speed. The measurements were repeated at
regular intervals, thus studying maneuvers and sea passage.
The method used is mainly based on extensive research and reference in the international literature
on the study of atmospheric pollutant monitoring using AIS, the monitoring of ship-generated emissions,
in particular of the cruise ships introduced at Piraeus port for 2018 , in particular, the cruise ships were
gathered from April to August 2018. The total number of ships was 280 cruise ships, calculating the four
most important pollutants emitting and plus a complete picture of all ships for the period mentioned
above.
