Mobile Source Emissions Inventory

This page last updated on May 15, 2015

The mobile source emissions inventory is ARB's tool for assessing the population, activity, and emissions from mobile sources. These inventories are constantly being revised and updated to support the latest air quality plans and regulations. Periodically these inventories are compiled and released to the public for use in transportation and air quality assessments both internal and external to the agency. Mobile source inventories are developed by the Mobile Source Analysis Branch in the Air Quality Planning and Science Division.
