The USA has been called “the Saudi Arabia of natural gas.” Natural gas is the cleanest fossil fuel and a highly efficient form of energy. It is composed mainly of methane, which when burned completely converts to carbon dioxide and water vapor. The following chart compares pollutant emission levels of Natural Gas, oil, and coal. Natural Gas outperforms other fossil fuels by virtually every measure. That’s why many companies, such as Ryder and Waste Management, have begun converting their fleets to CNG. Proctor & Gamble and Wal-Mart are also in the process of making the conversion.

Local governments are reducing air pollution with CNG-powered vehicles that include:
