Assess Potential Agency Size Changes that Impact Greenhouse Gases from Vehicles and Mobile Equipment


Step 1

Planned changes in a Federal agency's size, missions, transportation needs, and vehicle inventory all impact the strategic portfolio planning efforts that target greenhouse gas (GHG) emissions mitigation for vehicles and mobile equipment.

Under Section 142 of the Energy Independence and Security Act (EISA) and Section 8 of Executive Order (E.O.) 13514, agencies are required to develop a plan that will reduce fleet GHG emissions to meet Federally mandated petroleum reduction and alternative fuel increase targets. Agencies can use these plans as a basis for determining potential changes in fleet size and composition and should attempt to harmonize the ongoing development for these plans with GHG strategic portfolio planning efforts. FEMP's E.O. 13514 Section 12 Federal Fleet Management Guidance for Federal Agencies describes in detail the required plan components and strategies for meeting these requirements.

For both its fleet and non-fleet vehicles, agencies should include the following considerations when assessing potential changes in mobile source emissions:

  • Transportation needs: Will the agency or specific operating units have significant increases or decreases in travel requirements as a result of new policies, changes in mission, or operating approaches?

  • Vehicle inventory changes: Are there likely to be significant changes in the number of vehicles required by the agency to fulfill its missions? Will certain vehicle applications be eliminated or created?

Based on potential changes in agency site locations, agencies may also include projected changes in vehicle usage (i.e., miles traveled) and changes in climate or terrain that might impact the vehicle inventory needs.

Next Step

After assessing potential agency size changes, the next step in GHG mitigation planning for vehicles and mobile equipment is to evaluate a GHG emissions profile.
