OP-18: Campus Fleet

UNH has operated CNG fleet vehicles since 2000. As of July 2012, it operates a fleet of 29 vehicles including 13 transit buses, bi-fuel pickup trucks and passenger cars. In FY 2012, CNG vehicles logged over 200,000 miles and used over 37,000 gas gallon equivalents of CNG (replacing primarily diesel/B20).

The use of CNG in the UNH fleet over the past 12 years has reduced an estimated 600 tons1 of CO2 emissions and 125,000 gallons of gas/diesel fuel consumption with an estimated fleet fuel savings of over $250,000
With current market price of CNG, the fuel cost savings for this CNG fleet to UNH was approximately $72,500 in FY 122.
Transit is our biggest CNG user. In FY 12, approx. 30% of UNH transit miles were being run on CNG.
FY 12 saw dramatic increases in CNG utilization – growing to 18% of overall campus fleet fuel share

UNH worked cooperatively with the New Hampshire DOT to coordinate the first ultra-low sulfur B20 fuel supply at any state operated fueling facility. In August 2006, the facility, located at the UNH campus, opened and UNH began a conversion of all of its diesel fleet to year-round B20 operation.

In FY 2007, most diesel transit vehicles switched to B20 and UNH took possession of its first dedicated B20 fueled, California Air Resource Board Certified (CARB) low emission buses. In succeeding years, UNH Transit embarked on balanced fleet procurement - half B20 and half CNG.

UNH continues a transition of all post-1990 diesel vehicles to B20. As of July 2012, UNH had migrated over 85% of its diesel fleet to year-round B20. This transition has equated to a six year petroleum diesel consumption reduction of just over 90,000 gallons and estimated emission savings of 400 tons5 of CO2 with only minor incremental fuel cost increase. (Biofuel prices have fluctuated in a +/-5% range versus ULSD in recent years. In FY 2012 B20 was at a 5-7% premium over ULSD)

CNG and B20 are the focus alternative fleet fuels at UNH. (see attached) The UNH Transit Fleet runs almost 40% on CNG fuel in terms of net miles. The remaining 60% is virtually all B20 biodiesel year round. Although the quantity of CNG vehicles is small they utilized over 23% of total fleet consumption (up 10% from year prior)

FY 2013 gge % Total Fleet gge
Total Fleet Fuel 242,101 100%
CNG 47,771 20%
B20 86,709 36%

UNH would be over 50% alternative fuel fleet vehicle miles.

AASHE should really track an institutions fleet miles – and not fleet count.
