Carbon Footprint is the total amount of greenhouse gas emissions (GHG) such as carbon dioxide (CO2) that a business, organization, product, household or personal lifestyle produces. A bigger footprint is harder on the planet. The EPA has developed a Household Carbon Footprint Calculator to provide a rough estimate of a household's GHG emissions. Greenhouse gases act like a blanket by trapp heat in the atmosphere making Earth warmer than it would otherwise be.
