Establishing a Protocol For Conducting a Fleet Inventory


The ordinance or executive order should call for the city or county to conduct an extensive inventory of the vehicles in its fleet. This inventory should include not only the type and number of fleet vehicles, but also the amount and types of fuel used, the costs associated with their use, and the resulting pollution. This inventory is critical if goals are to be set and measured for the fleet.

Each fleet manager shall develop a 1992 fleet baseline (1994 for DIA) to facilitate the evaluation of annual Green Fleet Plans. Baseline information shall include:

1. Number of vehicles classified by year, make, model, engine size, VIN number, and drive train type (2-wheel drive or 4-wheel drive), rated vehicle weight;
2. Miles per Gallon per vehicle;
3. Type of fuel used;
4. Average cost per gallon (equivalent) of fuel;
5. Average fuel cost per mile;
6. Annual miles driven per vehicle;
7. Total fuel consumption per vehicle;
(Items 1 through 7 shall be provided by the Fleet Manager).
8. Vehicle function;
(Item 8 shall be provided to the Fleet Manager by the “user agency”).
9. Estimated emissions per mile for each pollutant by vehicle type/class (defined in 1 above) based on EPA tailpipe standards for the following:
Carbon Monoxide (CO),
Nitrogen Oxides (NOX), and
Particulate Matter (PM).
10. Carbon Dioxide (CO2) calculations based on gallons (or equivalent) of fuel consumed.
(Items 9 and 10 shall be provided to the Fleet Manager by Environmental Health Service).

Fleet Managers shall be responsible for providing this baseline data in a reliable and verifiable manner. The data will then be submitted to the Committee in conjunction with a proposed Green Fleets Plan (See section III below) for evaluation.
