When we talk about energy in particular, in fact there is a target that government departments have vis-à-vis their 1990 level of energy for buildings and vehicles. That's something we report to the public through the sustainable development strategies. So that's one target to work toward.
As well, I mentioned the LEED gold standard for new buildings. If we're hitting gold with that particular standard, most of the buildings would be at least 50% more energy efficient than if they were not meeting that target. We've seen a lot of progress in that area as well.
There's also a very important economic consideration when it comes to this. Maybe I could turn to my colleagues from Natural Resources on the federal buildings initiative, where there has been a lot of activity to upgrade buildings so energy is reduced.
