Modeling and Inventories
MOVES (Motor Vehicle Emission Simulator)
For answers to users' questions on MOVES, see our "Frequent Questions" page.
EPA's Office of Transportation and Air Quality (OTAQ) has developed the MOtor Vehicle Emission Simulator (MOVES). This new emission modeling system estimates emissions for mobile sources covering a broad range of pollutants and allows multiple scale analysis. MOVES currently estimates emissions from cars, trucks & motorcycles. We plan to add the capability to model non-highway mobile sources in future releases.
MOVES2014 will be a major update to EPA’s official model for estimating emissions from on-road mobile sources. It will include the benefits of the Tier 3 rule, as well as the impacts of other rulemakings promulgated since the last MOVES release, new emissions data, and new features that users have requested. We are working on a release of MOVES2014 as soon as possible. At the same time, we want to ensure that MOVES2014 operates properly over the full range of different use cases, and that the transition to MOVES2014 is as smooth as possible. Based on our most recent testing of the model, we now anticipate the release of the final version of MOVES2014 sometime in July, 2014. In the meantime, MOVES2010b remains the latest approved version of the model.
MOVES2010b. MOVES2010b is the latest version of MOVES and incorporates new features and a number of performance improvements compared to previous versions. Unless substantial work with MOVES2010 and/or MOVES2010a has been done, modelers should use MOVES2010b and take advantage of the improvements incorporated in this version. The version of MOVES2010b that can be downloaded here includes an updated version of the MOVES default database (dated 10/30/2012) that corrects an error in the 4/10/2012 database that was originally included with MOVES2010b. We recommend that users who have previously downloaded MOVES2010b, install this new version. See the MOVES2010b Q&A document below for more details about the new database.

This document provides guidance on appropriate input assumptions and sources of data for the use of MOVES2010, MOVES2010a, and MOVES2010b in SIP submissions and regional emissions analyses for transportation conformity purposes.
- Federal Register Notice of Availability: Official Release of the MOVES2010a and EMFAC2007 Motor Vehicle Emissions Models for Transportation Conformity Hot-Spot Analyses and Availability of Modeling Guidance (PDF) (December 20, 2010)
This notice approves MOVES2010a official use for quantitative CO and PM hot-spot analyses outside of California, and starts a two-year grace period before MOVES2010a is required to be used in these analyses for project-level conformity determinations outside California. This notice is applicable to current and future versions of the MOVES model, unless EPA notes otherwise when approving the model for conformity purposes. This notice also announces the availability of new guidance documents for: (1) completing quantitative PM hot-spot analyses using MOVES and other models; and (2) completing project-level CO analyses using MOVES.
- Federal Register Notice of Availability: Official Release of MOVES2010 Motor Vehicle Emissions Model for Emissions Inventories in SIPs and Transportation Conformity
This notice approves the use of MOVES2010 in official SIP submissions and starts a two-year grace period before MOVES2010 is required to be used in new regional emissions analyses for transportation conformity determinations outside of California.
Note: EPA subsequently extended the grace period to March 2, 2013 before MOVES2010 and minor revisions is required for regional emissions analyses for transportation conformity determinations (“regional conformity analyses”). See February 2012 final rule that provides an additional year to the previously established two-year conformity grace period at: www.epa.gov/otaq/stateresources/transconf/conf-regs.htm.
