A lot of staff have a real big interest, of course, in environmental issues. What we've found is that they're really committed and really interested, so we're tapping into that network, that grassroots network of staff who are really keen on greening, and asking how we enable them to do that, and not with central command and control. How we enable and give tools to staff to green in their area of responsibilities inside their areas is I think what we're looking at, for sure.
