I'm pleased you have asked that question, because in terms of the greening government strategy and the opportunities at SSC, we do have opportunities here and we are taking those opportunities seriously. We know that we, as a government, want to show leadership in this regard, and we are willing and able to do that.
I'm happy to talk about other things that we are doing in PSPC with respect to the greening government strategy, but I will hand it over to my officials to give a specific answer with respect to the dollar value.
