This is a terribly misleading comparison. Your CO2 emissions are more than your house and your car. Do you consume food that was farmed and shipped? Buy things that were made in a factory that produces emissions? Fly on airplanes?

Your personal CO2 emissions are more like a proportional fraction of global CO2 emissions. All of those factories and cargo ships and airplanes aren’t emitting CO2 just because. They’re doing it for individuals who buy those products and services, and therefore your household’s CO2 footprint is primarily external to the house itself.
