Map shows the difference in SO2 emissions in European shipping areas between the years 2014 and 2019. The map indicates the changes in ship SO2 emissions, 2019 minus 2014 situation. The numerical values reported in the map are tonnes of SO2 per each grid cell. It can be seen that in 2019 SO2 emissions from shipping in the English Channel and the North and Baltic Seas are much lower compared to 2014 than those in areas outside the sulphur emission control areas (SECAs), including the Mediterranean Sea, where SO2 emissions have remained largely unaltered or increased.
