Wise Gas, Inc. firmly believes that diesel school buses need to be changed.  

In addition to the dangers to the environment and the solid reliance on foreign oil, research shows that the diesel fumes and particulates are a definite danger to children's health.

Toxic chemicals in diesel emissions can increase the risk of asthma, lung and heart disease, and are responsible for as many as 125,000 cancers nationwide.

Diesel fumes can be particularly harmful to children, who face heightened exposure to diesel exhaust from the self-polluting nature of buses, and the tendency of buses to idle during loading and unloading periods. Research has shown that students on school buses are exposed to 5 to 15 times the levels of particulate pollution than at nearby monitoring sites.

Who hasn't been stuck behind a school bus and inhaled a lung full of diesel fumes? 

Have you seen the bus lines at schools when the last bell of the day rings?  A long line of idling school buses with open windows and young children sitting inside waiting for their classmates to board...breathing diesel particulates into their small airways.   

Experiments across the nation in alternative fuel school buses have led us to confirm our belief that this is one instance where the ideal alternative fuel is CNG. 

Biodiesel school buses experienced substantial issues in colder weather when the biodiesel fuel congealed in the tanks and caused early morning nightmares for school transportation.  The solution?  They discovered that the solution to this issue was to let the buses idle overnight in cold weather...

How does a bus idling overnight conserve energy, lower fuel costs or reduce emissions?  Whatever reduced emissions have been accomplished are diminished by the unnecessary idling waste.
