Mr. Gareth Llewellyn:

I cannot give the Chairman a geographical spot but, clearly, the impact of buses fuelled by hydrogen or electricity on the climate is very low. The benefit of public transport is quite high but those buses still need infrastructure to run on. TII will play an important role in facilitating that change. The point I made regarding modal shift was that the shift will probably be a policy decision. TII plays an important role in making sure that the infrastructure is in place and ready for a shift in modes.
