Carlson said that the average American is responsible for 50,000 pounds of carbon dioxide emissions each year. That is quite a substantial carbon footprint, which he defined as each person's "cumulative impact on global warming from the energy that you use from the electricity for your home, the gas in your car, flying in a plane."
50,000 pounds, that's 25 tons each year! I can't tell from this article if this figure includes the carbon footprint from items that we buy. If not, it's even worse.
