CNG Environmental Facts

Natural Gas has long been recognized as an excellent fuel to generate electricity, heat homes and fuel industrial facilities.  In much of the world, natural gas has also been a long established alternative fuel which is only recently experiencing a "revival" in the United States due to the fact that it is domestic, one of the cleanest burning and most affordable alternative transportation fuel available - directly addressing three key issues in our country:  National  Security, Global Warming & Air Quality and the Economy,

Commercially available light, medium and heavy-duty natural gas engines have demonstrated a reduction of more than 90% in harmful particulate matter which penetrates our lungs and more than a 50% reduction in NOx (Nitrous Oxide) by comparison to commercial diesel engines.  CNG vehicles also demonstrate 15% - 30% reductions in CO2 (carbon dioxide), the principle and most harmful greenhouse gas that contributes to global warming.  Natural gas vehicles also do not contain benzene, a common component of gasoline engine exhaust and a known cancer causing carcinogen.

Dedicated natural gas vehicles are the cleanest internal combustion engines available today, with bi-fuel vehicles (CNG and Gasoline) are still far less polluting than conventional gasoline or diesel powered vehicles.

Because natural gas is lighter than air, it does not have the ability to contaminate lakes, rivers or groundwater in the way that petroleum-based fuels do.  In the event of a leak or "spill", natural gas dissipates harmlessly into the atmosphere.  The costs to build and operate spill prevention and control facilities are not generally considered in comparing traditional fuels against natural gas. As such it is a hidden, though very real cost to owners of facilities dispensing and using liquid petroleum products.

Transportation exhaust accounts for 40% of urban pollution, with commercial vehicles being the biggest offenders.  More than 99% (99.8%, to be exact) of the vehicles on the roads of America are powered by conventional liquid fuels such as gasoline.

With nearly 200 million gasoline-powered vehicles on the road in America today, this is a major area of concern.  Those vehicles can not be converted to run on hybrid-electric or biodiesel - but they can be converted to run on natural gas.  Wise Gas, Inc. continues efforts to make this an affordable transition and calls upon the public agencies to begin replacing metro buses and school buses with Compressed Natural Gas engines and recommends that the private business sector examine their fleets to determine opportunities for change.
