MOVES4.0.0

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. MOVES is available under EPA's Open-Source Software policy.

MOVES4 replaces the MOVES3 series of models as EPA’s latest model for estimating air pollution emissions from cars, trucks, motorcycles, and buses, as well as many categories of nonroad equipment. MOVES4 allows users to model the benefits from new regulations promulgated since MOVES3 was released, incorporates the latest vehicle and emissions data, and has improved functionality—especially for modeling electric vehicles. The MOVES4.0.0 milestone page contains a list of changes between MOVES3 and MOVES4. For more information, see the MOVES Overview Report.

Additional resources are available on the MOVES web page, including a detailed “Question and Answer” document, MOVES Policy Guidance, MOVES Technical Guidance, technical reports that document the data and algorithms used in MOVES4. The website also includes links to tools for use with MOVES and information on MOVES training.
