Carbon Footprint Calculators
Have you ever wondered how much carbon dioxide (CO2) you release into the environment? There are a number of calculators online that can help estimate your personal carbon footprint. These calculators will ask you to fill in a wide range of data, such as where you live, what you eat, and what transportation modes you use.

They may also ask you how much you spend per month on energy; this data is used to calculate your usage based on national or regional average energy prices. Based upon the data given, the calculators then estimate your total CO2 emissions.
