This website helps you figure out how your lifestyle impacts the planet by asking you a bunch of questions and then giving you a score. Sometimes if you understand the consequences of your actions, it makes it easier to consider them in the first place.
Basically, the score is for your household. My score was 663 and 37 tons of carbon output, which contributes to global warming. Mr. K sort of killed with all the air travel. Another reason to love his company (feel the sarcasm)!
The scores range from 150 to 900 and lower is better on this test! The average in the US is 325.
