# NOx emissions in European shipping areas in 2019, Mar. 2021

This metadata refers to the map showing the NOx emissions from ships in European shipping areas (calculated as NO2) during the year 2019. The numerical values reported in the map are kilograms of NOx per grid cell area.

NOx emissions cause or add to regional problems, including acidrain and health problems in local areas such as harbours.NOx contribute to eutrophication, caused by excessive amounts of nutrient nitrogen and which can disrupt terrestrial and aquatic ecosystems. NO2 is also a precursor gas, forming new particles in the air or condensing on to pre-existing particles to form secondary PM (i.e. secondary inorganic aerosols)

The dataset has been prepared in the context of the development of the first European Maritime Transport Environmental Report (EMSA-EEA report, 2021: https://www.eea.europa.eu/publications/maritime-transport).https://sdi.eea.europa.eu/geonetwork/srv/api/records/f26cefae-6996-4c59-84de-2988fb1282da
