What the researchers at MIT found was that even in the U.S. people with the lowest energy usage, a homeless person, a five-year-old and a Buddhist monk, all have a carbon footprint twice as large as the average global citizen. This is because the services provided for every American, including infrastructure and public services, guarantee set a baseline that no American can drop below.
Bill Gates, specifically chosen for the study, has a carbon footprint about 10,000 times the average. Of course, he also has produced a great deal of wealth and growth for the world. In general, the researchers found that as income rises, so do emissions. A homeless person, who ate at soup kitchens and slept in shelters, had an average carbon footprint of 8.5 tonnes, still twice as much as the world average. Even monks, who lived half the year in the forest, had carbon footprints of 10.5 tonnes.
But the big question of how to lower carbon footprints is a tough answer. The study found that voluntary reductions is likely unobtainable for the average American. Considerably more can be done by the wealthy, but the best way to lower footprints is to tax carbon use which, Professor Gutowski says, is a hard pill to swallow, especially for politicians.
