The impact of shipping emission to urban air quality in Europe - Detailed port-city analysis
report
Air pollutants concentrations have shown a declining trend over the last decades in
Europe as a result of decreasing emissions in many sectors. However, the strong
emission reductions in some sectors, such as traffic, have shifted the focus to other
less strongly contributing sources, such as shipping whose emissions relative
contributions increase, in order to further reduce air pollutant concentrations.
In this report the influence of shipping emissions on the air quality in European port
cities is investigated with the chemical transport model LOTOS-EUROS. Using the
model’s source apportionment capabilities, the contribution of international and
inland shipping emissions to atmospheric air pollutant concentrations in 19
European port cities is computed.
In the emission set used in this study, the shipping emission on seas are derived
from Automatic Identification System (AIS) data of all ships sailing in the total
geographic domain of the calculations. These emissions are higher than the
emissions reported to the European Environment Agency (EEA) as a result of the
restrictive definition of maritime emissions in the national inventories of the EU
Member States which do not include any shipping emission outside the territorial
waters of the Member States. The total European NOx emissions used in this
simulation are ~9.3 Mton for the simulation domain of which 64 kton (0.7%)
originates from inland shipping and 2.2 Mton (23%) originates from international
shipping emissions.
