Many Houston-area vehicle fleets are converting to clean propane autogas to help reduce pollution and contribute to cleaner air — a significant concern for Houston, which was recently listed the seventh smoggiest U.S. city by the American Lung Association.
Houston-area propane autogas fleets include Humble, Splendora and Conroe Independent School Districts (ISD) — as well as Houston ISD, the nation’s largest school district, which operates 112 autogas vehicles.
