That's reassuring.
We have a bit of a contradiction, potentially, but I'd like to know if it is a contradiction. We understand that obviously your department is committed to achieving savings both through its management of property and through its various varieties of procurement. But now, to carry on with these greening initiatives, is this going to be a direct outlay of cost and expense? Or do you see this potentially being offset with not only environmental gain but cost savings, by embracing a technology that could actually be of real advantage to the government?
