Mr. Denis O'Sullivan:

I am not quite sure I understand the question, but, if I understand what the Deputy means, "Yes" is the answer. There is a saving of 20% in using natural gas instead of diesel. That is the immediate saving in switching. As we have outlined in Vision 2050, in due course we want to transition from natural gas to renewable gas which, in turn, will result in the use of a fuel that is fully carbon neutral in the transport fleet.
