America’s School Buses are Getting Greener
School is back in session and those iconic yellow school buses are back on the road. But what’s fueling them is changing. While more than ninety percent of all school buses do still run on diesel, many have been retrofitted to run cleaner. And buses that run on alternative fuel are making inroads. The three largest school bus manufacturers, Blue Bird, IC Bus and Thomas Built all offer eco-friendly options. Blue Bird’s propane bus sales have grown from zero to 20 percent of their overall sales in seven years.
