Before you start

To get a really accurate carbon footprint it would be handy to have the following at hand:

1. Your gas and electricity bills

2. Your annual mileage and MPG (miles per gallon) if you drive a motor vehicle.

But don't worry, you can still complete the calculations without them. Plus you can return at any time to redo your calculations when you have this information if you sign-up.
