Alternative Fuel Life-Cycle Environmental and Economic Transportation (AFLEET) Tool

Download Tools and Documentation

What is the AFLEET Tool?

The Department of Energy's Clean Cities Program has enlisted the expertise of Argonne develop a tool to examine both the environmental and economic costs and benefits of alternative fuel and advanced vehicles. Argonne has developed the Alternative Fuel Life-Cycle Environmental and Economic Transportation (AFLEET) Tool for Clean Cities stakeholders to estimate petroleum use, greenhouse gas emissions, air pollutant emissions, and cost of ownership of light-duty and heavy-duty vehicles using simple spreadsheet inputs.

The tool uses data from Argonne's Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) fuel-cycle model to generate necessary well-to-wheels petroleum use and GHG emission co-efficients for key fuel production pathways and vehicle types. In addition, Environmental Protection Agency’s Motor Vehicle Emission Simulator (MOVES) and certification data are used to estimate tailpipe air pollutant emissions. Various sources are used to provide default cost data, including the Clean Cities Alternative Fuel Price Report and American Recovery and Reinvestment Act awards.

Heavy-Duty Vehicle Emissions Calculator

The Heavy-Duty Vehicle Emissions Calculator bases its data and calculations on the AFLEET 2017 tool.  It is a simplified online tool for NOx funding projects. The calculator includes 4 fuel/vehicle types: diesel, electric, propane and natural gas. 

The GREET Fleet Footprint Calculator

The GREET (Greenhouse gases, Regulated Emissions, and Energy use in Transportation) Fleet Footprint Calculator created by Argonne National Lab was designed to assist in measuring the petroleum displacement and greenhouse gas emissions of medium- and heavy-duty vehicles and off-road equipment.

FHWA CMAQ Emissions Calculator

The Federal Highway Administration (FHWA) Office of Natural Environment has developed a series of tools to provide technical support and resources for the implementation of the Congestion Mitigation and Air Quality Improvement (CMAQ) Program. The  Alternative Fuels and Vehicles component provides estimates of emission reductions for CMAQ-funded projects where users are purchasing alternative fuel vehicles to replace a conventional fuel fleet or developing new alternative fuel infrastructure with restricted or unrestricted access. The tool uses emissions rates based on a national-scale run of the EPA MOVES model and alternative fuel factors from Argonne National Laboratory's AFLEET Tool.  Detailed use and methodology are explained in accompanying documentation provided on the FHWA website.  The entire toolkit can be accessed here

EPA Diesel Emissions Quantifier (DEQ or Quantifier)

The Quantifier is a tool to help fleet owners, state and local governments, and others to estimate emission reductions and cost effectiveness for clean diesel projects. Estimates are made using specific information about a fleet, such as miles driven, fuel mileage, et al. To access the Quantifier, click here.
