Regulate or develop self-regulators?

We just released the first report of data we've gathered using PaperCut, a printer/copier usage tracking software. There were a surprisingly large number of concerns by staff when we installed the product earlier this year, with references to Big Brother being common.
The intent of using this software is to build awareness of all staff about how much printing they do, what it costs both financially and environmentally, and how costs for printing on different devices (laser printers, color printers, copiers, etc.) vary. (See Self-awareness or surveillance.)
The goal is to reduce the amount of printing we do in the district, of course. But rather than set quotas and regulate how much individuals can print, we hope to develop awareness that leads to self-regulation. (This is akin to giving a person a bathroom scale and mirror instead of limiting their caloric intake on a weight reduction program.)
I firmly believe most educators will respond to this - and perhaps think of the approach when working with kids, working to create self-regulators rather than simply imposing limits.
