Heavy Duty Vehicle Emissions Calculator gauges emissions reductions on various heavy-duty vehicles

Fleet managers and state officials have a new resource as they evaluate how they will use their portion of the $2.9 billion Volkswagen Environmental Mitigation Trust Settlement money.

Argonne National Laboratory presented the Heavy-Duty Vehicle Emissions Calculator (HDVEC) during the recent FedFleet 2018 meeting in Washington, D.C. The online resources is designed to provide provide state officials and fleet managers an accurate tool to gauge and compare vehicle technologies for emissions reductions across various medium- and heavy-duty vehicles.

The HDVEC is available on the Argonne website and is linked at the NGVAmerica’s website, the HDVEC estimates the vehicle operation nitrogen oxide (NOx) and fine particulate matter (PM2.5) as well as the well-to-wheel greenhouse gas emissions (GHGs) of current commercially-available alternative fuel medium- and heavy-duty vehicles eligible for funding under the VW settlement. 

The tool can calculate results for three project types allowable under the Trust Settlement:

  • Environmental Mitigation with Scrappage – new alternative fuel versus diesel, plus additional benefit from early retirement of the scrapped vehicle.
  • Environmental Mitigation with Repower – vehicle after repower versus diesel before repower.
  • Clean Vehicle Replacement – new alternative fuel versus diesel.
  • Clean Vehicle Replacement – new alternative fuel versus diesel.

The HDVEC was developed using Argonne’s Alternative Fuel Life-Cycle Environmental and Economic Transportation Tool (AFLEET) available here.  AFLEET Tool 2017 uses emissions data from both the U.S. Environmental Protection Agency’s Motor Vehicle Emission Simulator and Argonne’s Greenhouse gases, Regulated Emissions, and Energy use in Transportation models.
