The ones I can tell you about off the top of my head are things like the buses, where we are working on making more energy-efficient buses. Some of them are hydrogen buses now. We are moving in that direction. Whether they are all going to switch, I couldn't tell you, but there have been moves there. We have also moved to more energy-efficient light bulbs in many cases around the Hill. I think we are replacing the light bulbs in some of the fixtures here and there. Certainly, when renovations to this building take place, if and when that ever happens—we've been working on it for 20 years or so—then there will be changes in that respect as well.
Those are areas where we are working. We have certainly moved on the use of more environmentally friendly paper than we used to use. Certainly there has been a substantial increase in documentation being sent online rather than by paper.
I'd say we are moving in that direction. Those are the general comments I'd make. I'm not an expert in this area, of course, but those are areas in which I notice changes that are taking place.
