CNG isn’t a zero emission technology, but according to the Environmental Protection Agency, it emits 80 percent fewer ozone precursors and over 95 percent fewer particulates than conventional gasoline-powered vehicles. In addition to being cleaner, compressed natural gas is also 30 to 40 percent cheaper than gasoline or diesel on a mileage basis.
Chairman of Yellow Group, Michael Levine says that “new, growing CNG taxi fleets will provide benefits not only to the drivers and passengers in the form of lower fuel costs and clean, green performance, but to the City of Chicago at large, as greenhouse gas emissions are significantly reduced.”
