Thank you for the question. It's a robust one, to say the least. I will turn to Robert as well in our Office of Greening Government Operations for part of the answer.
From the real property branch perspective, the targets that are set in terms of the GHG reductions are linked very strongly to energy savings. Somewhere between 80% and 90% of the reduction will be achieved through energy reductions. Having set the target for 2020, that's the target that we're working toward. I can tell you that in terms of energy savings, from 2001 to 2010 we have reduced our energy consumption by 19%. Our GHG reduction target—and there are so many of these targets that they do get confusing—runs from 2005 to 2020. So in pursuing that reduction, we're also achieving reductions in our energy consumption. It's not a stated target for reduction, but it is achieved as a product of pursuing the GHG reduction.
