On-Road Emissions Inventory Program
The on-road emissions inventory is an estimation of the population,
activity and emissions of the on-road motor vehicles in use in California. The emissions inventory models
calculate the contribution of gas, diesel, and electrically powered passenger cars, light, medium and heavy-duty
trucks, motorcycles, school and transit buses and motor homes for the years 1970 through 2040.For further questions, please contact Jeff Long, Manager of the Analysis Section of the Mobile Source Analysis Branch.
