Post-it note economics

I am not sure if this falls under psychology, ecology or economics. My friend works for a company which is currently facing severe economic difficulties and management is frantic about reducing costs. Half-jokingly someone suggested that they use both sides of a post-it note. When I heard it, I was surprised but after giving it some thought I realized it's not such a bad idea. If we use less paper, that's good for the environment, isn't it? The only time I used both sides of a post-it note was when, having run out of sets, I had to make do with the last note in the pack. It never occurred to me to think of the environmental impact so I'm now reconsidering my one-side only use.
