Alternative Fuel Vehicle
Law & Politics
Local government must develop and
implement vehicle fleet plans
At least 75% of the total local government
fleet must operate on alternative fuel
(Reference Arizona Revised Statutes 9-
500.04, 49-474.01, 49-541, and 49-571)
Energy Security

Cleaner Burning Fuel
Carbon Reduction: Diesel creates 22.4 lbs of carbon
for each gallon burned vs. Natural Gas that creates
15.1 lbs of carbon for each gallon burned.
An average garbage truck burns 40 gallons of fuel per
day/10,560 gallons per year. Switching to Natural Gas
can reduce carbon footprint by 77,088 lbs per truck
annually.
According to America’s Natural Gas Alliance ONE CNG
refuse truck = taking 325 cars off the road

National Trends
“At our current rate of conversion, we plan to have more
than 3,100 trucks … on natural gas and other alternative
fuels by the end of 2015” (source: Republic Services website)
“Waste Management … will announce it is pushing
forward on a nationwide plan to convert all of its 18,342
trucks from loud and smoky diesel engines to quieter
and cleaner compressed natural gas-powered
machines.” (source: Houston Chronicle chron.com)
