BERLIN - FEBRUARY 21: Cars, trucks and other traffic clog the A100 ring road at rush hour February 21, 2007 in Berlin, Germany. Auto emissions has become a hot political topic in Europe as the European Council has proposed legislation to cut emissions of carbon dioxide to 130 grams per kilometer for cars produced starting 2012 in an effort to slow the warming of the Earth's atmosphere. Germany's auto industry in particular is opposing the plan. (Photo by Sean Gallup/Getty Images)
