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)

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)
