ENVIRONMENTAL BENEFITS OF CNG-FUELED VEHICLES. TOPICAL REPORT NOVEMBER 1986-MAY 1987

A study was performed to identify significant environmental, safety, and economic benefits associated with CNG-fueled vehicles relative to gasoline-, methanol-, and diesel-fueled vehicles. From an environmental viewpoint, natural gas was shown to be a cleaner fuel than gasoline or diesel, and is considered to be as safe or safer than gasoline. The exhaust emissions from natural gas-fueled engines are typically lower in CO, reactive HC, particulates, metals, and aldehydes than from gasoline or diesel fuel. An opportunity to expand CNG usage into urban bus and truck fleets by replacing diesel fuel was identified.
