There are many examples, and we're coming across them more and more often, of where there is a good intersection point between what is the right thing to do for the environment and what is fiscally prudent to do.
An example we talk about sometimes—it's relatively easy for those of us who use a lot of paper to understand—is printers. You buy a printer that can print on both sides of the paper; it's a duplexing capability, and as long as you actually use that feature, the statistics suggest you could save about $700 per printer per year. Even though the printer might cost a little more, you multiply that out across the number of people who actually have printers in the federal government and you can see there can be a savings.
It's a matter of looking at the whole life cycle of the product to see where savings are possible.
