Carbon Monoxide Emissions

Caption: New research shows that levels of carbon monoxide dropped sharply in the Beijing area between 2007 and 2008, due to traffic restrictions imposed because of the 2008 Summer Olympics. Knowing the levels of carbon monoxide allowed the researchers to infer that carbon dioxide emissions also dropped dramatically. The science team used satellite measurements, combined with output from a computer model like that illustrated above, to quantify the amount of reduction in this major greenhouse gas.
