This gives us a data set that allows us to look at change, to see how this situation is changing from year to year.

If you look at European harbours in the Mediterranean area like Savona, Barcelona and others, you can really see the impact of the new regulations – you can see a decrease by two thirds – 66% – of SO2 concentrations in harbours.

There's quite a high level of air pollution over the Mediterranean. And there's a lack of data about this, we don't know enough. So we need more observations. And this ship is a very good platform for making observations, because it covers a large area, particularly around the coast where we often have air pollution problems.
