Mr. Hugh Creegan:

"I do not know" is probably the fairest answer of the lot. There is a lot of carbon assessment in infrastructure development. It is a key component we evaluate as part of most infrastructure development. I am less sure we need it for residential or commercial development. The reason is we can have a different metric that gives the same view on the transport side. Even in the absence of a pure carbon assessment, the very fact of whether there are services there to serve development, is not a strong indicator of whether it is positive or negative. I would be guided by others as to whether it is a worthwhile addition.
