Carbon footprint - Prevent global warming

Just calculated my own carbon foot print using the calculator provided on BP.com website. While I am glad to know that my footprint is about the same as the US average, its still disappointing because average US resident is probably several times higher in Carbon usage (5% of the global population with 25% of energy usage) and is adding to global warming faster than other people around the world. I need to work harder on somehow mitigating this.

Try determining the Carbon footprint for yourself. The websites with such calculators are rather basic, simplistic, and certainly unattractive, but they are providing a useful service to the mindful.

p.s. It was fascinating to see how much air travel contributes to our carbon burden!
