Motor Vehicle Emission Simulator (MOVES)
Abstract
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. It is used to create emission factors or emission inventories for both onroad motor vehicles and nonroad equipment. MOVES2014a is the latest version of MOVES. It incorporates significant improvements in calculating onroad and nonroad equipment emissions. It does not significantly change the criteria pollutant emissions results of MOVES2014 and therefore is not considered a new model for SIP and transportation conformity purposes.
