The European Sea Ports Organisation’s (ESPO) 2018 environmental report shows that air quality continues to be the main priority for European ports. The Port Authority of the Balearic Island is aware of this and has been working hard since 2016 to establish the level of air quality in its ports and to find out how port activity may be involved in this rating, in line with the Port Authority of the Balearic Island's Environmental Policy.
The Port Authority of the Balearic Island and the University of the Balearic Islands (UIB) have been working together on the development of a project which now enables air quality at the Port of Palma to be monitored through this control panel which is updated eight times a day and records the average hourly value of the seven stations located in the Port of Palma. Each of these stations has nanosensors that can measure carbon dioxide, NO2, O3, PM10 and SO2. In total, there are 113 sensors in the Port of Palma that record data every ten minutes. The air quality rating has been established based on the same criteria as those set by the Balearic Island Regional Government for its reference stations across the region.
The Port Authority of the Balearic Island plans to extend this experience to the ports of Alcudia, Ibiza, La Savina and Mahon in 2019.
