( From C.R.S. 24-30-1104 (2) (c) (II))
Beginning on January 1, 2010, the executive director shall purchase motor vehicles that operate on compressed natural gas, subject to their availability and the availability of adequate fuel and fueling infrastructure, unless the increased base cost of such vehicle or the increased life cycle cost of such vehicle is ore than ten percent over the cost of a comparable nonflexible fuel vehicle.
In the last year there have been 2 recent studies analyzing the use of CNG as an alternative fuel:
- Experiences with Compressed Natural Gas in Colorado Vehicle Fleets, August 2012, from the Colorado Energy Office.
- The Colorado EnergySmart Transportation Initiative, March 2012, from the Colorado Department of Transportation and the Governor's Energy Office
More information on CNG vehicles can be found on the Colorado Natural Gas Vehicle Coalition website. The Greening Government Transportation Efficiency Audit report from the Colorado Department of Personnel and Administration may also be of interest. General information on natural gas in Colorado can be found on the Colorado Geological Survey website.
