A carbon footprint is a measure of the total greenhouse gas emissions linked to a person, organization, or activity, typically expressed as carbon dioxide equivalents. The option describing the carbon dioxide emitted from fossil fuel consumption by a person best fits this idea, because it captures the idea of personal emissions from energy and transport use. It’s not just about how much energy a household uses (emissions depend on how that energy is produced and consumed), not about emissions from an entire country, and not about carbon stored in trees, which is about sequestration rather than emission.
