CNG Vehicles

As we move forward, purchasing “Compressed Natural Gas” (CNG) vehicles will be the first option when replacing older inefficient vehicles wherever practicable as a result of Senate Bill 13-070.  This will allow the state to take advantage of Colorado’s vast reserves of natural gas reducing our dependence on petroleum, creating new jobs, and reducing our carbon footprint.
