Global emissions of carbon dioxide from fossil fuel combustion and cement porduction rose from 22.6 billion tons in 1990 to an estimated 31 billion tons in 2007 - a staggering 37 percent increase. This is 85 million tons of carbon dioxide spilled into the atmosphere each day- or 13 kilograms on average per person. The annual increase in emissions shot from 1 percent per year in 1990s to 3.5 percent a year from 2000 to 2007- with China accounting for most of that remarkable leap.
