Abstract: Air pollution is the most relevant externality of maritime transport and its effects are  more acute in urban areas. As Short Sea Shipping (SSS) services call ports frequently and expend  significant time in port, both the overall turnaround time and the port city closeness, become  critical in their sustainable performance. This paper analyses the impact of maritime transport
on Spanish SSS ports and identifies the ideal ones, reflecting the differences in their sustainable  performance and finally identifying the characteristics that a harbour needs to gather in order to  minimize air pollution impact in the maritime transport sector.

 

MARPOL Annex VI seeks a progressive reduction in SOx emissions limiting the  sulphur content in marine fuel oils. The  actual sulphur cap of 4.5 % shall be reduced  to 3.5 %, by January 2012 and furthermore  down to 0.5 % by January 2020 (International  Maritime Organization, 2008b). Since July  2010 the sulphur limit in the ECA-s is of  1 % and will be further reduce to a 0.1 %  by January 2015 (International Maritime  Organization, 2008b). Progressively restrictive  policies regarding NOx emissions are also  being enforced by Annex VI, for instance  Tier III applicable for new constructions  after January 2016 (International Maritime  Organization, 2008b).
