Carbon footprint is the amount of greenhouse gases measured in amount of carbon dioxide, produced by human activities. A carbon footprint can be measured in terms of tons of CO2 equivalent per year. An organization’s or individual’s carbon footprint can be broken down into primary and secondary footprints. Primary footprint is the direct emission of greenhouse gases (GHG) from the burning of fossil fuels while secondary footprint is indirect emission of GHG during the lifecycle of products used by an individual or organization.
