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. This change in emissions, determined from a computer model along with satellite measurements of carbon monoxide, enabled scientists to infer that carbon dioxide emissions also dropped dramatically, an indication of the effect that reduced traffic can have on the greenhouse gas.
