I'm very confused by the other section and see no explanation anywhere but it takes up 75% of my pie chart :/

Edit: Even if everything is set at zero everyone still raises the earth by 1.8 degrees Fahrenheit.

If this site wants to educate people they need to give out more information but as of now it looks like they are just gathering data and making a silly pie chart and map.

As noted in the how it works link (posted twice on this page, or at the bottom of your chart), they've assumed you have the average emission levels for all sorts of other activities, such as home telephone service, car purchases, apparel purchases, and, of course, alcohol and tobacco.

Interesting, they assume you get 20mpg. Does the fact that I get 50+ change my impact, per miles driven? Apparently not.
