MOBILE4.1 is the latest revision to EPA's highway vehicle mobile source emission factor model. It will calculate emission factors for hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx) for eight types of highway vehicles. EPA is requiring that States and others preparing emission inventories for nonattainment areas for CO and ozone to use MOBILE4.1 in the development of the base year 1990 emission inventories required under the Clean Air Act of 1990. Relative to MOBILE4, it contains numerous revisions and provides the user with additional options for modeling highway vehicle emission factors.
