Paschal Donohoe (Dublin Central, Fine Gael) | Oireachtas source

I am well aware of the Senator's point.The challenge we have is that the cost of the buses to which the Senator refers is multiples of that relating to the vehicles we can access which are diesel-powered but which are considerably cleaner and more efficient than they have been in the past. I have engaged with Dublin Bus on this matter and it is considering all kinds of measures to make its fleet more environmentally friendly. The particular challenge in obtaining coaches or buses propelled by alternative fuel sources is that they are much more expensive than the most efficient diesel buses.
