I think the answer is that we're looking at that now in the broader sense of green and clean technology, and how procurement could be leveraged to support that initiative.
Over the many years, because I'm getting old now.... I was around 20 years ago when there was a very strong push for green products. For example, 20 years ago, had you wanted to buy paper in the federal government that had recycled content, it didn't exist. Through constantly advising the private sector that this is where the government wanted to go—of course, over the years virtually all the paper we buy has a high recycled content, and it's very environmentally green—we've totally transformed the market. It wasn't just us, but the world at large. You would have to pay a premium now to find paper without green content, so yes.
