   Here are some benefits from using CNG as a fuel

   Making America less dependent on foreign oil is a national priority.
   Reduces urban smog reduction, burns cleaner and produces lower levels of harmful pollutants.
   It’s safe and lighter-than-air, CNG is nontoxic and disperses quickly. It has a higher ignition temperature than gasoline and diesel fuel, which reduces the chances of accidental ignition.
   Contains no particulates like diesel fuel and reduces emissions of carbon dioxide – the principal “greenhouse” gas.Vehicle emissions are lower with natural gas than with gasoline because ignition temperatures are higher and combustion is more efficient.
   Engine maintenance cost can be reduced by extending time between oil changes. The particulate materials that are produced during the combustion cycle cause engine oil to get dirty are not present in the CNG.
   Readily available. The United States has a huge natural gas resource base. All 50 states and all major metropolitan areas have access to natural gas.
   It’s the most practical. Any vehicle can be converted. Half of infrastructrue already exist, we have 6 million miles of underground gas piping.
   Economical – Natural gas is piped directly to the fueling station, reducing the cost of transportation.

   CNG Emissions Benefits:

   Reduction of Benzene by 97% (diesel) and 99% (gasoline)
   Reduction of Nitrogen Oxides (NOx) more than 50% (diesel) and 60%-90% (gasoline)
   Reduction of Carbon Dioxide (CO2) by 10% (diesel) and 30%-40% (gasoline)
   Reduction of Carbon Monoxide (CO) by more than 90% (gasoline and diesel)
   Reduction of Non-Methane Hydrocarbons (NMOG) by 50-75% (gasoline)
   Reduction of Lead and Sulfur by 100% (diesel and gasoline)
   Reduction of Smoke and Particulate Matter (PM10) up to 90% (diesel)

   Exposure to the levels of suspended fine particulate matter found in many U.S. cities has been shown to increase the risk of respiratory illness and other health problems. Much of the particulate matter in urban areas is due to transportation. CNG produces very tiny amounts of particulate matter.

   CNG produces far less urban emissions than diesel vehicles. For example, even when the stringent 2010 EPA heavy-duty engine emission standards become applicable, CNG will be producing only one-sixth the NOx of comparable diesel engines. NGV’s have a deserving reputation for being one of the cleanest transport fuels available, not just with respect vehicle emissions, but also for fuel production. Even when measured against other ‘clean’ fuels or methods, such as gasoline-electric hybrids, CNG emissions are frequently lower.

   CNG also poses fewer environmental hazards than other fuels. In the event of an accident, natural gas dissipates into the atmosphere rather than spilling on to the ground – a major benefit for our waterways and wildlife.
