To reduce greenhouse gas emissions, California is pursuing the ambitious goal of adopting five million zero-emission vehicles (ZEVs) by 2030. Progress toward this target will affect future state-generated transportation revenues collected from vehicle owners and operators. This paper uses simple spreadsheet models to estimate how different rates of ZEV adoption will impact state-generated transportation revenues. We project future transportation revenue in California through 2040 under two scenarios. The first scenario assumes that ZEV ownership continues at its historical rate of net increase, approximately 26,000 vehicles per year. The second assumes that California reaches its goal of five million ZEVs by 2030. The projections show that the user fees levied on ZEVs by provisions of SB1 can replace and potentially even exceed the revenue to the state that will be lost because of declining gasoline sales tax revenue.
