Important Note About MOVES Versions

In general, states should use EPA’s latest model, MOVES4, to take advantage of its improved capabilities and updated default values.

Users should consult the Federal Register Notice of Availability for MOVES4 and the MOVES4 Policy Guidance (see the MOVES latest version page) before doing additional work with a version of MOVES3. The conformity grace period for the use of MOVES2014 ended on January 9, 2023. At this point, versions of MOVES2014 and MOVES2010 may not be used for any regulatory purposes.

• See MOVES Onroad Technical Reports and MOVES Nonroad Technical Reports for information on data and analysis incorporated in the MOVES versions.
