text: Paris recently (according to source two article "Paris bans driving due to smog" by Robert Duffer) came up with a brilliant idea of partial driving ban to clear the air of the city. They took days were only even or odd liscense plated cars would drive or they would suffer a fine. However public transit was free throughout the week. This promoted less congestion and smog which is much better for the enviorment by lowering the amount of pollution in the ozone layer. As well as a cheaper way to commute. "Congestion was down 60 percent in the capital of France, after five-days of intensifying smog...rivaled Beijing, China, which is known as one of the most polluted cities in the world". This shows just how out of hand the smog had gotten but with limiting the amount of cars used they managed to clear over half of it! Making the world greener than before.
