To begin using the calculator, select an option above and calculate your CO2 emissions in that area.

If you are unclear at any time about your actual numbers, you can use the national averages. Just click the link and they will be auto-entered in the form. Remember that using the national average will only give you a rough estimate of your carbon footprint. You can always grab your electricity bill or check the mileage on your car the next time you return to begreennow.com and enter the actual values.
