Two major parts of the solution to climate change are switching to rail transport and promoting it as much as possible and developing district heating systems in our towns and cities. Both solutions require appropriate development densities that are much higher than is the norm in this country. As well as being an important element of tackling climate, higher density, when done right, lends itself to healthier and more thriving communities and better supports business, schools and other public services. Does the Tánaiste acknowledge the importance of appropriate density to support rail development and district heating across our urban areas? Will he get back to me in writing, if he cannot answer now, on the progress of two important documents, namely, the sustainable and compact settlements guidelines and the guidance on transport-orientated development for major urban centres?

I accept that rail transport and district heating will make significant respective contributions to the climate change agenda. A bit more work is needed. The Minister for the Environment, Climate and Communications recently brought a document to the Government on a policy framework for district heating. However, there is the size of the country and other factors to take into account. There is one development in Tallaght, Dublin, that has been successful. There could be another at Poolbeg but we need local actors to get their act together in terms of pipes and so forth. There is significant investment going into rail transport. Deputy Shanahan might close his ears to this but the Midleton-Cork-Mallow rail service was designed around density and to enhance further density in that corridor as part of the EU's recovery and resilience programme.
