Divvying up fair share of carbon emissions

“Most of the world’s emissions come disproportionately from the wealthy citizens of the world, irrespective of their nationality,” says physicist Shoibal Chakravarty, noting that many emissions come from lifestyles that involve airplane flights, car use and the heating and cooling of large homes. “We estimate that in 2008, half of the world’s emissions came from just 700 million people.”
