December 19, 2012 - California currently maintains over a dozen major programs that are intended to support the development of energy efficiency and alternative energy in the state. Over the past 10 to 15 years, the state has spent a combined total of roughly $15 billion on such efforts. In response to the Supplemental Report of the 2012-13 Budget Package, this report provides an overview of these different programs, as well as a preliminary assessment of them in terms of priority, overlap, and redundancy. We find that the state currently lacks a comprehensive framework that fully coordinates the state's energy incentive programs to help ensure that the state’s goals are being achieved in the most cost-effective manner. The absence of such a comprehensive framework (1) results in some level of program duplication, (2) results in some departments making policy choices that may not be aligned to legislative priorities, and (3) makes it difficult to compare effectiveness across programs. As a result, we recommend that the Legislature develop a comprehensive strategy for meeting the state’s energy efficiency and alternative energy objectives. In general, the comprehensive strategy should specify: (1) the state’s energy efficiency and alternative energy goals, (2) how programs should fit together to achieve the state’s goals, and (3) how program effectiveness will be measured.
January 5, 2021 - This report is intended to provide guidance for the Legislature on how to evaluate the merits of state-funded green stimulus proposals. When reviewing such proposals, the Legislature faces two basic questions to evaluate whether they are worth pursuing: (1) what effects is the proposal likely to have on certain short-term economic conditions, such as employment and economic output; and (2) what short- and long-term environmental benefits could the proposal achieve?
February 24, 2014 - In order to minimize the negative economic impact of cap-and-trade, it is important that auction revenues be invested in a way that maximizes GHG emission reductions for a given level of spending. In reviewing the Governor's proposed expenditure plan, we find that there is significant uncertainty regarding the degree to which each investment proposed for funding will achieve GHG reductions. This uncertainty is the result of several factors, including there being only limited data and analysis provided by the administration, as well as the fact that the level of emission reductions achieved would depend on the specific projects funded by departments. Given these concerns, we recommend that the Legislature direct ARB to develop metrics for departments to use in order to prospectively evaluate the potential GHG emission benefits of proposed projects, as well as direct the board to establish a set of guidelines for how departments should incorporate these metrics into their decision making processes.
January 6, 2020 - In this report, we assess the effects of the state’s major policies intended to reduce emissions from the generation of electricity.
December 15, 2021 - Chapter 135 of 2017 (AB 398, E. Garcia) requires our office to annually report on the economic impacts and benefits of California’s statutory greenhouse gas emission targets. This report provides our assessment of the effects of major programs in the agricultural sector that are aimed at reducing emissions and sequestering carbon, as well as identifies key issues for the Legislature to consider as it makes future policy and budget decisions.
February 23, 2022 - This brief provides our assessment and recommendations on the Governor's proposed 2022-23 zero-emission vehicle package.

November 14, 2017 - In this report, we provide background information on ZNE buildings as well as the administration’s approach to meeting the executive order’s goals for state‑owned ZNE buildings. Then, we assess the administration’s approach to these buildings. Finally, we recommend that the Legislature adopt its own policies related to ZNE for state buildings and take steps to ensure that it has adequate information to evaluate future administration proposals for state‑owned ZNE buildings.

December 21, 2018 - Chapter 135 of 2017 (AB 398, E. Garcia) requires our office to annually report on the economic impacts and benefits of California’s statutory greenhouse gas (GHG) emission goals—statewide emissions to 1990 levels by 2020 and to 40 percent below 1990 levels by 2030. This report provides a conceptual overview of the potential economic effects of policies intended to help meet these goals—both positive and negative—as well as identifies some key issues for the Legislature to consider when designing and evaluating state climate policies. In a companion report, Assessing California’s Climate Policies—Transportation, we provide more detailed information and comments on the state’s major policies aimed at reducing emissions from the transportation sector.
