text: Of all the advantages of limited car usage the most attractive one would definetly have to be reduced pollution and greenhouse gas emissions. Not only will people save money on fuel in communities that forbid the usage of cars but they will save the planet as well. According to the article "In German Suburb, Life Goes On Without Cars" by Elisabeth Rosenthal "Passenger cars are responsible for 12 percent of greenhous gas emissions in Europe ... and up to 50 percent in some car-intensive areas in the United States." The information shows that a large amount of gas emissions can be produced by automobiles. Assume that there were a lot of cities that had incredibly low rates of car usage. If those city's greenhose gas emission levels were compared to those of an average car filled city then it would be logical that the car-free city produced less greenhouse gasses.
