This brief describes residential carbon dioxide emissions profiles and calculations of carbon dioxide reduction measures. The brief contains a profile for energy consumption, energy costs, and the emissions of greenhouse gases resulting from the direct and indirect use of energy in the household. The goal of this brief is to discuss numerous ways for ordinary homeowners to cost-effectively reduce their carbon emissions in their own homes. The document distinguishes energy use and emissions by end uses (such as heating, cooling, and appliances) after consideration of the various fuels used for each end-use and the carbon dioxide content of fuels. This household profile is an amalgamated average for a great variety of climate zones, heating and cooling requirements, types of installed equipment, size and age and condition, and numerous other factors that differ from your consumption and CO2 emissions patterns.
