Mr. Philip Hughes:

Understanding the nature of the problem and instituting and supporting political moves to help in this regard would help, including moving towards having Single European Sky legislation, increasing harmonisation and looking at making investments in the longer term in systems to enhance efficiency. This is what I have in the master plan and the committee can see the business case. We have done large-scale simulations with it. We have run it on our systems in Brétigny-sur-Orge and we can see what the impact of some of these solutions would be. It is possible to overcome the problems.

The other aspect concerns sustainability, which is a societal issue. Having the political will to move towards using sustainable aviation fuels is a key enabler to addressing this issue. It is not going away. We can see the impact of the climate change we are already witnessing and, therefore, this is something we need to be aware of.
