I've not watched the movie yet, so perhaps this is addressed there, but I am kinda suspicious of guilt offset schemes.

Also, the websites estimates an Australian's carbon footprint is about 50 times that of a Brit...wtf are they doing down there?

Mine came back as 3.8. It says: "Your total score is 0.4x the national average". However, it does fail to take into account that I drive a v8 with open headers. Though, I do drive it sparingly these days, and typically just to the gym and back. I bus to and from work.

They assumed you just use electric cutouts to intimidate the Hondas and Mitsubishis. That setup doesn't actually produce any carbon, much like cake eaten after work on Thursdays isn't fattening so therefore doesn't count against your diet.
