• Propane is clean burning. Tests conducted by the EPA show that propane
engines produce 60 percent less ozone-forming emissions than reformulated
gasoline. Recent tailpipe emissions tests performed on Orange County (California) Transit Authority's propane buses showed they emitted 87 percent less
total hydrocarbons, 50 percent less nitrogen oxides, and 40 percent less particulate matter than gasoline-fueled buses.
• More than 90% of all propane used in the US is produced domestically.
