MOVES2014a: Latest Version of MOtor Vehicle Emission Simulator (MOVES)

You will need Adobe Reader to view some of the files on this page. See EPA’s About PDF page to learn more.

EPA's MOtor Vehicle Emission Simulator (MOVES) is a state-of-the-science emission modeling system that estimates emissions for mobile sources at the national, county, and project level for criteria air pollutants, greenhouse gases, and air toxics.

MOVES2014a is the latest version of MOVES:
  • It incorporates significant improvements in calculating onroad and nonroad equipment emissions.
  • It does not significantly change the criteria pollutant emissions results of MOVES2014, and therefore is not considered a new model for SIP and transportation conformity purposes.
  • MOVES2014a Questions and Answers (PDF)(6 pp, 527 K, EPA-420-F-15-046, November 2015) highlights the differences between MOVES2014a and earlier versions of MOVES, and explains EPA policy on using MOVES2014a in State Implementation Plans and Transportation Conformity Analyses.

Downloading MOVES2014a

  • Download the November 2016 Update to MOVES2014a (EXE)(62 MB) : The November 2016 Update to MOVES2014a fixes issues with the MOVES Fuel Wizard and updates emission rates for dioxins and furans. EPA has discovered an error in the Fuel Wizard that, in some cases, can result in incorrect adjustments to fuel formulations when users change the ethanol content of the fuel. The effects of these adjustments on emissions are small, but we recommend that MOVES users who plan to use the Fuel Wizard install and use this update to MOVES2014a for all future work.
  • After downloading the setup file, run MOVES2014a-Setup-20161117.exe and follow the on-screen instructions to complete the MOVES2014a installation.
  • NOTE: More information on which fuel scenarios were affected by the error and how the fix impacts a sample county-level emissions inventory are documented in the Fuel Supply Report on the MOVES Technical Reports webpage (/moves/moves-technical-reports). Details on using the Fuel Wizard can be found in the MOVES2014a User Interface Reference Manual (PDF)(59 pp, 605 K, EPA-420-B-16-085, November 2016).
