Mr. Graham Doyle:

Public transport contributes less than 5% of overall emissions. Nevertheless, it is important that we use the public transport that we control to show leadership, and it is an area in which we can have a direct impact.

We have committed not to buy any more diesel-only buses by mid-2019. That is significant. We are now looking at trials as to how we get there. They will begin shortly, notably in Dublin and Cork. I will ask Ms Graham to speak about some of the plans for trains and electrification of the network.
