MOVES2014b: Latest Version of Motor Vehicle Emission Simulator

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.

MOVES2014b is the latest version of MOVES:
  • Compared to MOVES2014a, MOVES2014b incorporates significant improvements in calculating nonroad equipment emissions.
  • It does not significantly change the onroad criteria pollutant emissions results of MOVES2014, and therefore is not considered a new model for SIP and transportation conformity purposes.
  • MOVES2014b Questions and Answers (PDF)(4 pp, 90 K, EPA-420-F-18-014, August 2018) highlights the difference between MOVES2014b and earlier versions of MOVES and explains EPA policy on using MOVES2014b in State Implementation Plans and Transportation Conformity Analyses.
