text: One of the more serious and more recognized problems from car usage is the steady increase of greenhouse gas emissions produced from vehicles all over the world. Passenger cars are responsible for 12 percent of greenhouse gas emissions in Europe. Vauban, Germany is an example of the effort being made to reduce these greenhouse gas emissions, this experimental city is trying to remain "car-free" and in doing so the city itself has to make its own changes. This basic precept is being adopted around the world by trying to compact suburbs and make them more accessible by public transportation."When i had a car i was always tense. I'm much happier this way" said by heidrun walter(source 1). With this new experiment, people are finding ways to adapt and live the changed life while others actually feel better off.
