Off-topic: How ec0-friendly are you?

This is a little late for Earth Day, but this Carbon Quiz gives you a quick look at how big a carbon dioxide footprint someone with your lifestyle leads. I miss being deep green (15,000 pounds per year) due to all the flying my job involves. The quiz says there are ideas on how to reduce your household carbon footprint, but it doesn't link to the article and I can't find it on a quick skim, unfortunately. I did find this site, which has some common sense tips.
