This is another tool that has been developed to give the general public an idea of how ecologically they live in terms of sustainability. It is a quiz in which you answer questions such as how many people live in your house and what size it is, whether the energy for heating it comes from renewable sources or not, what your most frequent mode of transport is, etc. It has been modified to take account of different countries and even different regions, although some people feel that the tool cannot really be applied to localities.
Here are some links to websites dealing with ecological footprints:
University of Texas site that goes into more detail about ecological footprints, and from which you can download the Excel sheet used for the calculations, check out the ecological effects of air travel, and estimate your own ecological footprint (using US figures).
Prosus site that is based on a conference in Norway in 2001 on the use of ecological footprints in Europe. Includes a comparison of the strengths and weaknesses of the ecological footprint concept as well as other useful information.
