Supply Chain and Propane 101

Propane cuts 96 percent of emissions compared with clean diesel buses, according to a separate West Virginia University study, and at a cost that’s 30 to 50 percent less to operate per mile than diesel buses. Previous studies proved that diesel exhaust contains toxic particulate matter that contributes to allergies, asthma and lung cancer — especially in children.

In a real-world study conducted by West Virginia University, propane autogas buses were found to cut 96 percent more NOx emissions compared with clean diesel buses.
