Just calculated my footprint at http://footprint.wwf.org.uk/
It is just a guide but shocking none the less. My biggest carbon consumer is all those flights to Spain. I have already resolved to cut the number of flights by at least half and perhaps replace one with a train journey.
I have been working on reducing my carbon footprint in terms of food and the home for some time already.
The WWF website has lots of other ideas for bringing this appalling figure down.
