What is your carbon footprint? Like the real estate slogan, it depends on location, location, location.
For a single-person household earning less than $10,000, living in California, the annual carbon footprint is about 16 tons of greenhouse gasses. But for a couple earning $90,000 living in the Bay Area, it's about 57 tons annually. That is almost the same as a family of five living in St. Louis, with half of the annual income.
