The 2025-26 Budget:
Cap-and-Trade Expenditure Plan
GABRIEL PETEK | LEGISLATIVE ANALYST | FEBRUARY 2025
SUMMARY
The Governor proposes roughly $1.8 billion in discretionary cap-and-trade expenditures in 2025-26.
The Governor’s plan funds a number of programs and activities that were initially to be supported with the
General Fund, but then were shifted to the Greenhouse Gas Reduction Fund (GGRF) through the 2024-25
budget process in order to address the multiyear budget problem. Additionally, the Governor proposes two
new fund shifts in the budget year to help reduce pressure on the Motor Vehicle Account (MVA), which faces
insolvency in 2025-26 absent corrective action.
We find that while the proposed fund shifts present trade-offs, the Governor’s GGRF proposal for 2025-26
largely adheres to the expenditure plan the Legislature agreed to as part of the 2024-25 budget package.
However, GGRF revenues are subject to substantial uncertainty and are trending lower than forecasted as
of the middle of the 2024-25 fiscal year. To the extent these somewhat lower revenue patterns persist, the
Legislature may need to make modifications to the GGRF expenditure plan for 2025-26. Should they further
weaken, modifications to 2024-25 GGRF spending may also be necessary. Moreover, to the extent that the
General Fund condition worsens, the Legislature could be faced with making ongoing reductions to base
programs. If that were to occur, the Legislature might want to consider using this fund source as a tool to
help preserve its highest-priority activities—which may differ from those in the current plan. Accordingly, we
recommend that the Legislature closely monitor GGRF and General Fund revenues and be prepared to adjust
expenditure plans as necessary.

of $1.1 billion in revenue, with annual amounts
