My household and individual ecological footprint (more accurate).

No comments:
Why post details of my household/individual ecological footprint? Well: 1. I have the information and have been calculating it in reasonable detail and with fair accuracy by the same method for yrs now, for both work and personal purposes; 2. People are increasingly interested in their footprint and growing numbers do a calculation eg via a website; 3. I've said previously I would publish a more detailed footprint document, having done some estimates using websites (see Sept 9 '07 posting); 4. As someone who has for yrs been campaigning to get greener society with much lower footprints and environmental impacts, people may be interested to see if I try to practice what I preach; 5. The information is quite interesting; 6. The figures show that you can lead a pretty normal life and have a low footprint - I have a car, I eat meat, I have holidayed I dont live in a teepee eating only leaves or in the latest high-tech, ultra-expensive green get a low footprint, though I do aim to be very efficient and to prioritise.

My total 3 person household ecological footprint for 2007, was 1.04 hectares (10,400 square metres). This is 0.35 hectares (3500 square metres) per person. This amounts to approx 5 tonnes of carbon, or 1.7 tonnes per person per yr – about half the national average of 10.22 tonnes given on the website

The 2007 footprint compares to a 1999 household score of 1.47 hectares (14,700 square metres), which is 0.49 hectares (4,900 square metres) per person. The 2007 figure is 29% lower (meaning annual cuts, from an already low base, of 4% per yr on average).

According to the Ecocal model software ( ) a sustainable score for a UK household is 0.4 – 0.5 hectares per person.

A reasonably detailed breakdown of the score can be viewed here. I've placed a link just under About me and Biography in the right hand column of this blog site so that its conveniently available.
