Darn, forgot to post my own answer on there to start you all off!
I'm probably up to 3.5 on the scale. I'm not particularly dedicated to being carbon neutral, however, I am a Geologist and work for a conservation charity here in the UK so I am quite carbon neutral without meaning to be.
Some things that I do that aren't on the list are:
~ Keep the house thermostat low. This is good for three reasons: 1) Makes your bills cheaper! 2) Stops your from getting dry skin and headaches! 3) Your body burns more energy in cooler temps (keeping you warm), so dropping the thermostat a couple of degrees burns off more calories!
~ My laptop is energy star
-ed, as is my tv.
~ I don't drive when I can walk to my destination (but must admit to hating buses, so I would go by car if necessary!).
