NRCan, or that department, is the repository of a lot of expertise in the area of energy efficiency and greenhouse gas emissions. They are our best experts in the federal government in that area. We rely in large part on their expertise to advise us on what can be achieved across federal departments, what's realistic and what are good ambitious goals to be achieved in different areas, and whether the technology exists to make good progress, and if so, at what rate. That's their role. It's largely as a technical adviser to us, as leaders, to help departments be ambitious in their own plans and in setting their own targets.
My colleague, Mr. Shugart, mentioned that establishing those targets is important. I think he referred to the 31% target that was set out. Actually, in our guidance in 2006, we didn't move away from that target for GHG emission reductions in federal buildings. In fact, it was the target we endorsed at that time to build on the progress, as you mentioned, that we achieved through to 2004, reaching a 24% reduction since 1990.
