Dr. Kelly de Bruin:

There is a lot of movement in that specific area. The European tax directive does not allow us to tax kerosene, for example. They now want to tax kerosene and they are allowing nation states to do so. Ireland has been quiet on this issue when we could have made a bit more noise. Other countries have implemented a passenger tax, for example, to indicate that they think that aviation should be taxed. Many other European countries indicated they think something should be done. Ireland did not do so.

I feel as though the movement is already there.
