The Heavy-Duty Vehicle Emissions Calculator (HDVEC) was developed to estimate the vehicle operation nitrogen oxide (NOx) and particulate matter (PM2.5), as well as the well-to-wheel greenhouse gas emissions (GHGs) of commercially available alternative fuel medium- and heavy-duty vehicles. This tool is ideally suited to aid fleets and decision makers compare vehicle technologies for emission reductions and consider allocation of funding.

The tool can calculate results for 3 project types:

  • Environmental Mitigation w/ Scrappage

    – New alternative fuel versus new diesel, plus additional benefit from early retirement of scrapped vehicle.
  • Environmental Mitigation w/ Repower

    – Vehicle after repower versus diesel vehicle before repower.
  • Clean Vehicle Replacement

    – New alternative fuel versus new diesel.

The first two are specifically for environmental mitigation projects such as those funded under the Clean Diesel Settlement or the Diesel Emission Reduction Program, while the third provides results without the scrappage benefit. The HDVEC tool was developed using the AFLEET Tool 2020, available at: https://greet.es.anl.gov/afleet. AFLEET Tool 2020 uses emissions data from both the EPA’s MOVES and Argonne’s GREET models.
