Data Fields

All monetary units are fractions of a whole dollar, so that a quantity of 50 cents would be entered as 0.5000 for example. The dollar year is the dollar year of the Contract.

  • Fuel Type. One of the following: Gasoline, Diesel, Electric, Aviation Fuel, Marine Fuel, or None. This field cannot be changed but shows the relevant fuel type for subsequent fields.

  • Fuel Cost. The total cost in dollars per unit of fuel. This field is prepopulated with the cost for the fuel type shown, depending on the state. It includes both state and federal fuel taxes, which are shown in their respective columns in this table. The user may change fuel costs, but if the cost changes are due to changes in federal or state fuel taxes, then those values also need to be adjusted.

  • Federal Fuel Tax. The federal fuel tax per unit of fuel. The federal fuel tax is default to the current tax per gallon (or other unit of measure as appropriate for your country) and may be changed as desired. Defaults are provided for the different Fuel Types.

  • State Fuel Tax. The state fuel tax per unit of fuel. In a similar manner to federal fuel tax, this field allows you to override the state fuel tax rates.

  • Fuel Per Mile. Units of fuel used per mile.

  • Well-to-Pump CO2 (lbs). For each unit of fuel used, the number of pounds of CO2 produced to get the fuel to the point of delivery.

  • Tailpipe CO2 (lbs). For each unit of fuel used, the number of pounds of CO2 produced by the vehicle directly (as opposed to the well-to-pump cycle).
