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.
- Using MOVES for SIP and conformity purposes
- Using MOVES for Estimating Greenhouse Gases and Fuel Consumption
- MOVES2010 Training Sessions
- MOVES Technical Background Contains technical details on MOVES design and inputs, and information on previous versions of MOVES.
A new version of MOVES is now available. MOVES2010a incorporates new car and light truck energy and greenhouse gas rates and a number of other improvements. Unless substantial work with MOVES2010 has been done, modelers should use MOVES2010a and take full advantage of the improvements incorporated in this version.

General Information about MOVES2010a
- MOVES2010a Questions and Answers (PDF) (5 pp, 525K, EPA-420-F-10-050, August 2010) This document highlights the differences between MOVES2010 and MOVES2010a and explains EPA policy on using MOVES2010a in State Implementation Plans and Transportation Conformity Analyses.
- MOVES2010 Mobile Source Emissions Model: Questions and Answers (PDF) (9 pp, 128K, EPA-420-F-09-073, December 2009) Describes the model and provides general information for model use.
Using MOVES for SIP and Conformity Purposes (also see MOVES2010a Questions & Answers)
- Direct Final Rule and Notice of Proposed Rulemaking: MOVES Regional Grace Period Extension This rulemaking extends the deadline by which MOVES must be used for conformity determinations.
- MOVES2010 Policy Guidance (PDF) (17 pp, 148K, EPA-420-B-09-046, December 2009) This document describes how and when to use the MOVES2010 emissions model for SIP development, transportation conformity determinations, and other purposes.
- 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. EPA will be publishing a separate Notice of Availability to approve MOVES2010 for project-level transportation conformity hot-spot analyses when guidance is finalized.
- MOVES2010 Technical Guidance (PDF) (48 pp, 281K, EPA-420-B-10-023, April 2010) This document, which was updated April 2010, provides guidance on appropriate input assumptions and sources of data for the use of MOVES2010 in SIP submissions and regional emissions analyses for transportation conformity purposes.

Using MOVES for Estimating Greenhouse Gases and Fuel Consumption
- Using MOVES for Estimating State and Local Inventories of On-Road Greenhouse Gas Emissions and Energy Consumption – Draft (PDF) (67 pp, 1.5MB, EPA-420-D-12-001, January 2012)
This draft technical guidance describes how to use EPA’s MOVES model to estimate greenhouse gas emissions and/or energy consumption from on-road vehicles in a state or metropolitan area. EPA is accepting comments on this draft guidance until March 31, 2012. Submit comments via email to Laura Berry, berry.laura@epa.gov. After this date, EPA may revise this guidance without further notice. Contact: Laura Berry, phone 734-214-4858, email: berry.laura@epa.gov.
