Heather has just worked out our carbon footprint for the last tax year, and found that we generate 3 times the sustainable global average. She has put a heap of effort in, based around 3 months of measuring and tabulating our household inputs and outputs. She has separated the routine elements from the irregular, and filled in for the rest of the year. We are both glad that we have completed our baseline measurements, and can take the compost out in peace.
The only changes we've made so far based on this info are switching from butter to margarine and putting up a 'No Advertising Please' sign on our letterbox. Recycling 3kg of junk mail a week generated about 6.5kg CO2 equivalent for each of us every week!
Here's the breakdown. Click through for the details - still working out how best to share this type of data. Eventually we plan to publish the detailed calculation spreadsheet in case anybody else would like to check their household out -- first I have to automate it further and port it all across to Google Docs.
