Feebates Research Contract

Potential Design, Implementation, and Benefits of a Feebate Program for New Passenger Vehicles in California


AB 32 specifically states that if the Pavley regulations do not remain in effect, ARB shall implement alternative regulations to control mobile sources to achieve equivalent or greater reductions of greenhouse gas emissions (HSC 38590). ARB is currently evaluating the use of a feebate program as the mechanism to secure these reductions, should that be necessary. A feebate regulation would combine a rebate program for low-emitting new vehicles with a fee program for high-emitting new vehicles. This program would be designed in a way to generate equivalent or greater cumulative reductions of greenhouse gas emissions compared to what would have been achieved under the Pavley regulations.

As described in the Scoping Plan (Volume I, p. C-61), ARB is commissioning a study to analyze the benefits from the implementation of a feebate program for new vehicles in California, both in place of and in addition to the Pavley standards.  The study will assess elements of program design including fee and rebate levels, point of regulation, implementation strategy, consumer response, and interaction with other AB 32 programs.  

Based on standard research contract processes, ARB issued a research solicitation to University of California and California State University researchers for pre-proposals to analyze the potential design and benefits of a feebate program for California.  Through this solicitation process, the team from the Institute of Transportation at University of California, Davis, led by Dr. David Greene and Prof. David Bunch, in collaboration with researchers from University of California, Berkeley and Irvine campuses was selected to develop a full proposal for funding. 

The full proposal was reviewed by the Research Screening Committee (RSC) at their November 2008 meeting and approved by the Board in December 2008.  Work on the contract began in January 2009.


The research team released an Interim Statement of Findings with preliminary study highlights in May 2010.

The final report was approved by the RSC in January 2011.  An updated final report was revised in February 2012 to correct numerical errors, see Excerpts of Corrections (.pdf, 91 KB).  The new report, appendices, and detailed modeling results are available to download by viewing the project page in our Research Catalog.
