While many of the current "green" trends in IT are hype, I'm pretty sure we can do better than this:
What you see here is an 8P8C (not RJ-45) connector, individually packaged and labeled. While sorting through storage at work the other day, I cam across an entire bag of these, probably about a hundred, all individually bagged and labeled. The manufacturer probably used about as much plastic for the packaging as for the connectors themselves.
Unfortunately there was no vendor name on the bag, so I can't say who to avoid purchasing from. I can only hope they get a clue.
