The California Air Resources Board (CARB) invites you to participate in a workshop on Wednesday, January 17, 2024, to discuss updates to CARB’s official on-road mobile source emissions inventory model, EMFAC. At the workshop, which will be the second of a series of workshops, staff will introduce potential updates to methodologies and data sources for the next version of the model, EMFAC202Y. A subsequent workshop in 2024 will cover more updates on methodologies and updated emissions outputs relative to the current version of the model, EMFAC2021. The release of EMFAC202Y is tentatively scheduled for 2025.

Background

The EMFAC model is the primary tool that CARB uses to assess emissions from on-road motor vehicles including cars, trucks, and buses in California for regulatory and planning efforts. For example, CARB recently used EMFAC to support multiple incentive programs and regulations, and to develop planning documents including the Mobile Source Strategy and the State Strategy for the State Implementation Plan. To better estimate and evaluate the impact of various incentive programs and regulations and to support future air quality planning, CARB needs to update mobile source analysis tools with the most up-to-date data and methodologies. In addition, as the transportation sector in California is transitioning to zero-emission technologies under the direction of the Governor’s Executive Order N-79-20, the current capacity of EMFAC needs to be expanded.
