Mr. George Hussey:

I will go back to the Cathaoirleach's first question as I do not particularly have a point to make on permeability. It is sort of a common objective we should all share, but in our submission we referred to developing an evidence base to support planning authorities at all levels to quantify the impact of spatial planning policies on greenhouse gas emissions in a consistent way. It is a fertile area for all manner of different approaches to emerge. It would probably be very useful system-wide if some work were done on trying to help local authorities to find a reasonably consistent methodological approach they could all use to help that. It is not just transport but also the built environment and the electricity emissions, potentially, as well. We could go across the whole energy piece in assessing whether a development in area X is preferable to one in area Y. I am sure there are all sorts of other planning aspects to this as well, but from a greenhouse gas emissions perspective alone, there is something positive to be said for it.
