And where is Adobe's office? Did they reclaim brownfield? Did they put their offices in a central location accessible by transit? Did they use their $$$ to revitalize an economically neglected neighborhood?
This is the same thing I think about when people tell me how "green" Google is. Nothing like sitting in your air conditioned office, looking across your manicured campus, created in plowed-over soybean field or whatever, and ruminating over your dot-com billions, and thinking, "I need to do something for Mother Gia."
In any event, NOTHING would do more for "saving the earth" than eliminating offices altogether. Why do people have to spend an hour "getting to work" just to sit in their cubes with their laptops? If our industry claims to want to "reinvent business," let's lead by example and make telecommunting the de-facto way to work.
