-The National Emissions Inventory (NEI) is a comprehensive and detailed estimate of air emissions of criteria pollutants, hazardous pollutants and greenhouse gases from 188 onroad air emission sources (mobile sources such as highway and border crossing vehicles electricity measurement), 248 nonroad air emissions sources (mobile sources such as off-highway vehicle gasoline measurement), 703 nonpoint air emissions sources (such as industrial processes, oil and gas exploration and production) and 5818 point air emissions sources (such as chemical and organic solvent evaporation measurement) at the US county level.
