Just done mine (again) for a proposal someone was making to a green organisation. I have to say it was a much better experience than last time (when it felt like filling in a tax return). I did it here
It's a very static picture though. I do like their giving recommendations, although the ones that involve me persuading my landlord to spend money on eco-improvements have got to be a slight longshot.
I really want to take part in a carbon progress monitor that tells me that over the last few years switching to ecotricity, finding a farmers market, buying (and then barely driving) a prius, refusing lots and lots of long haul conferences, getting occasional trains half way across europe & so on mean that I am 80% less crap than I could have been if I had an eco lobotomy.
Anyway because of my carbon disclosure thread I'll have to show you mine (feel free to add yours to the comments if the mood takes you!)
CARBON FOOTPRINT (3 person household):
home heating 3.79 tonnes
appliances 1.26 tonnes per year
emissions from transport 4.48 tonnes per year
If that was our total footprint it wouldnt be too bad (UK average is 12 tonnes per person) but given the lack of questions about food, imported & manufactured goods and so on you've got to suspect that its only the stuff that's actually using energy in your immediate surroundings that gets counted here...
