Thanks to the U.S. Environmental Protection Agency for allowing the use of its household emissions calculator.<br />
<ol>
    <li>Allow yourself 10-15 minutes to enter the data. </li>
    <li>To get the most accurate results, gather your recent electric or natural gas 
        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. </li>
    <li>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.</li>
    <li>After your calculations are complete, we will help you learn about actions you can take to reduce your carbon footprint.</li>
    <li>Calculations are based on the <a href="http://www.csu.org/residential/prices/sheet/item1130.pdf" target="_blank">residential rate sheet</a> published at the start of the year.</li>
