Use this calculator to measure your individual impact on the environment in terms of the amount of greenhouse gases you produce, measured in units of CO2. After assessing your carbon footprint consult our list of helpful CO2 reduction tips – designed to empower and encourage you during the process of reducing your carbon footprint and global warming.
To get started, if you are a Marin County resident select the San Francisco Bay Area as the California region you live. Then select how many persons are in your household and your household annual income, this will populate the remainder of the calculator with initial values based on averages of households like yours.
Within each field of the calculator you may choose to select the default, average value or enter specific data (select the applicable field and type in the data, or use the up arrow to increase the value or the down area to decrease the value).
The calculator currently estimates emissions for average products. If you pay more for organic products than conventional products then you may consider reducing your answers to compensate for higher prices.
Future versions of the tool will allow users to select organic and adjust emissions appropriately based on difference in price and, to the extent data is available, based on energy inputs to different farming systems.
