Charlotte-Mecklenburg Schools


Charlotte-Mecklenburg Schools (CMS) is no stranger to the busy schedules that come with a new school year. Racking up nearly 130,000 miles every day to pick up 127,000 students, CMS understands the importance of running an efficient transportation department. In 2019, the district chose to add 28 propane-powered Blue Bird Type C school buses to its fleet. With less downtime and lower maintenance and fuel costs than diesel, propane autogas keeps buses out on routes while providing the school district with savings they could pass on to the classroom. And thanks to a grant from the North Carolina Department of Public Instruction, there was no additional cost to CMS to upgrade the buses to propane autogas.

CMS is one of more than 930 school districts across the country integrating propane autogas school buses into its fleet. The district made the transition to propane autogas because of the benefits the fuel offers throughout the lifecycle of the buses, including a healthier ride to school for students and the lowest total cost-of-ownership.


CMS is one of the largest districts to implement propane autogas into its fleet, serving 127,000 students and driving 130,000 miles every day.


CMS drivers report that they prefer the quiet operation of the propane autogas engine compared to noisier diesel engines.


CMS works with a propane autogas supplier to conveniently schedule refueling every other day with a propane delivery truck.


Propane autogas school buses can produce up to 96 percent less nitrogen oxide (NOx) emissions than clean diesel buses.
