The National Mobile Inventory Model (NMIM) is a free, desktop computer application developed by EPA to assist in the development of estimates of current and future emission inventories for on-road motor vehicles and nonroad equipment. NMIM uses current versions of MOBILE6 and NONROAD to calculate emission inventories, based on multiple input scenarios that are entered into the system. NMIM can be used to calculate national, individual state, or county inventories.
