Abstract:California has established itself as a leader in efforts to reduce greenhouse gas emissions from transportation. However, the state has not reflected its ambitious policies for greenhouse gas (GHG) reduction and climate action in its practices for allocating state transportation funding. This paper reviews the complex systems through which California generates and allocates state revenue for transportation investment. It finds that the state’s framework for funding transportation projects and programs is disconnected from its GHG goals, reflective more of historical political deals than of contemporary climate policy. The paper also suggests preliminary steps for revising this framework to reinforce GHG reduction goals. Such recommendations are particularly salient given the state’s recently completed study of road user charges as an alternative transportation revenue source, as well as the passage of new legislation that restructures the state’s fuel taxes (Senate Bill 1, 2017). Implementation of road charges or any other new or revised transportation revenue source would need to address the disposition of revenues generated. This paper argues that California should use any such opportunity to align the distribution of state transportation dollars with its climate objectives, not fall back on status quo allocation practices.
