How would you calculate a personal ecological footprint?

How exactly do you calculate you carbon footprint?

• Answer:

  A.) Multiply your monthly electricity bill by 105. B.) Multiply your monthly gas bill by 105. C.) Multiply your monthly oil bill by 113 (if you don't use either B or C, enter 0). D.) Multiply total yearly mileage driven by .79. E.) Multiply the number of flights 4 hours or less by 1,100. F.) Multiply the number of flights 4 hours or more by 4,400. G.) Do you recycle newspaper? If no, add 184. If yes, add 0. H.) Do you recycle aluminum and tin? If no, add 166. If yes, add 0. A+B+C+D+E+F+G+H = your carbon footprint. A number below 6,000 (reflected in pounds per year) is excellent. Over 22,000? Not so great. Anywhere from 6,000 to 15,999 is good, while 16,000 to 22,000 is average. http://www.forbesautos.com/news/headlines/2008/april/fdc042108-green-carbon-living
