Following Charles Stross' lead, I went through this Guardian link last night on how to reduce emissions. In everything but flying it looks like as a household we come out saving about 4.4 tonnes as we do most things right, but then I'm screwed on flights, doing 16 shorthaul and 4 longhaul this year. At least I have cut down since last year by over 70% so I am reducing my footprint.
Amused by the 'take up vegan' idea - can't think of anything worse. Wonder if I get points for giving up all no meat items...
And in Scotland the whole solar power thing.... well...
