1. Current Emissions
2. Reduce Emissions

To get the most accurate results, gather your recent electric, gas, and/or oil bills so you can use real numbers for your household’s energy consumption. Remember that your energy bills vary by season, so use an average of winter and summer values if you can.
Allow yourself 10-15 minutes to enter the data.
After entering data, use the TAB key to continue moving through each section of the calculator. When you get to the end of a section, click “Next Section” to move on.
