The aviation industry is clearly a very high-carbon-using industry. I think I am right in saying that at the moment it is outside the EUTS and that there is a programme to get it into that scheme. Of course, we will recognise that aviation is part of our everyday life. It is not something you can turn off overnight. There are big technological advances going on in the aviation world. We applaud that. We applaud the fact that the industry is making every effort to recognise the need for carbon reduction globally, and we would be completely mad not to listen to what it has to say.
