The following maps breakdown port tonnage by direction and aggregates ports within each NUTS3 region for the EU’s Atlantic Area. Additionally, pie charts for each NUTS3 region show either the source for inwards tonnage or the destination for outwards tonnage. The benefit to disaggregating port data by direction and composition of source/destination by NUTS3 region is that it can show at a glance the reliance of a region on a port in terms of size if the port is exporting or importing; and what the dependent markets are. The maps clearly show a higher amount of red for inwards flow of tonnage compared to outwards flow indicating significant imports from the rest of the world (Non-EU). The MOSES estimate of inwards tonnage of 651 million tonnes for the Atlantic Area in 2018 is compared to a MOSES estimate of 390 million for outwards tonnage in 2018.

The top three NUTS3 regions for inwards port tonnage in 2018 are Seine-Maritime in France (Port of Le Harve), Cádiz in Spain (Port of Algeciras) and Thurrock (Port of London). The first Portuguese region, Alentejo Litoral is at sixth (Port of Sines) and the highest Irish port is Dublin (Dublin Port) at fourteenth.

Looking at outwards tonnage, the top two NUTS3 regions are in reverse order compared to inwards direction tonnage, with the top region being Cádiz in Spain (Port of Algeciras) followed by Seine-Maritime in France (Port of Le Harve). Third place goes to the UK but well to the north with Falkirk region (Forth Ports) and again the first Portuguese region, Alentejo Litoral is at sixth (Port of Sines). The highest Irish port for outwards tonnage is Dublin (Dublin Port) at seventeenth. In both maps when looking at the light blue element of the pie chart indicating that an Atlantic Area country is the source/destination, three routes are highlighted, Dover-Calais, Dublin-Holyhead and Belfast to Cairnryan. This shows the dependence of these routes on internal Atlantic Area transport and highlights the issue for these ports as all are now on the border of the EU customs union since Brexit.
