From the sunny shores of California to the chilly Nor’easters of New York, school districts all across the country are finding success with propane autogas school buses. Not only are propane autogas buses reducing emissions and improving the local environment as a result, but they’re also quiet, safe, and have the lowest total cost-of-ownership for districts. Today, more than one million students are transported safely to school and home each day on propane autogas buses and those numbers continue to grow.

Based on the most recent data from the Propane Council, since 2012, propane autogas school bus registrations have increased by more than 700 percent. Now, more than 15,600 propane autogas school buses from 850 school districts and bus contractors in 47 states are on the road every day. Ten states – Texas, California, Oregon, Pennsylvania, Wisconsin, Illinois, New York, Minnesota, Florida, and Ohio – have more than 500 propane autogas buses in operation, and districts in 22 of the 25 largest metro areas are now using propane autogas school buses.

While the numbers are impressive, they really aren’t surprising once you consider the benefits of propane autogas buses.

School districts love that propane autogas buses have lower fuel and maintenance costs, allowing them to pour that extra savings into student-based programs. Parents appreciate that students aren’t coming face-to-face with a black cloud of harmful diesel exhaust every school day, something the World Health Organization classifies as a carcinogen. And drivers notice the quieter ride, allowing them to more easily focus on the road and keep students safe.
